I am the very proud owner of a standard seqential turbo with proven 385 FWBHP or 316RWHP, and it is all down to Carl Haywood building a superb extended street ported engine and mapped/tuned by Geff @ Reworx.
For you guys wanting the nitty -gritty, we spent this morning on CPL Racing\'s Dyno Dynamics rolling road [01795 668778] completing the top end mapping having completed 7 power runs we ended with 315.7RWHP and 255 ft. lbs @ 5500. The engine produced 280 RWHP @ 5500 peaked @7200 and maintained 310 to 8200, boost was set @ 14psi to 6k where it dropped to 13 through to 8200 water temp was a constant 85c throughout with inlet temp @ 26c AF was 10.5 /11.

on behalf of ant

Went to Abbey Motorsport yesterday morning with the new FD, for those of you who dont know it is a Panspeed tuned type R with a T04S large single turbo, not to mention many other mods including a Panspeed mapped ECU. Getting to the point, I am really pleased with the results, the cars is clearly setup to run 1.0bar boost which I guess means it must have uprated injectors/fuel pump which was a bit of unknown. As usual it was running MEGA rich at idle, and AFR was good at full bore and has all the characteristics of good Japanese mapping (no part throttle work then!, makes it a bit of a jerky b*stard in traffic until you get used to it. Anyway here are the results.

355.3bhp @ 6881rpm - at the rear hubs, this equates to about 400bhp at the flywheel.

275.8 ft/lbs torque @ 6246rpm - again at the hubs, flywheel figure likely to be abot 305ft/lbs torque.

Not bad considering Tim\'s \'interesting\' installation! I think it was leaking boost all the time too? Should be interesting with boost control and little less air leaking...oh, and considering the intake temps seen perhaps an intercooler would be nice :) "Never" I think Tim said at the time! May be a bit of W.I. in the future...

Geff reckoned it felt as fast as the red car was on the road on the way back home, I guess 256atw with about 950kg? is pretty good power/weight.

Whats the calculation again?
Title: Dyno sheets and discussion for UK Rotaries!
Post by: bnaellis on February 21, 2004, 05:22:48 PM
Formula for calculating Flywheel Horsepower:

Drivetrain loss on an FD RX-7 is about 18%. Therefore take 18 from 100, and you get 82. Then take the rear wheel horsepower figure and divide it by 0.82.

e.g. 217rwhp / 0.82 = 265fwhp

Title: Dyno sheets and discussion for UK Rotaries!
Post by: J4P RX on February 21, 2004, 06:53:50 PM
Yeah, for whats on the car its very good but I knew this as  it does shift.  Thing is I have now seen the graph, and its not particularly good.

I have a dip where the 2nd turbo comes on, and then between 5000 rpm and 5500 rpm I go from 170 ATW to 255 ATW which seems pretty steepfor 500rpm.  This may explain why in the wet I can just light it up in 3rd on the 2nd turbo.  I suppose this is a good thing though, better to have the power there.

Trouble is right after my power actually drops by about 10, before gradually rising up to the 274 ATW then tailing off after about 6500.  Now Im just wonder what it would be like if the end of my power graph was smooth and not the mess it looks on paper.  Should be a fair bit to come.  I think ill leave it pretty much as is though.  No point in getting a Power FC for the small gain if any and I dont like them.

I wonder if there\'s any chance that the weird look of the graph is wheel-slip related?  I assume it was on rollers?

Hi Lee,

What boost was that dyno\'d at ?? I guess numbers are  high for the mods mainly to do with the fact when it was dyno\'d  it had a freshly built engine ?

rgds
Title: Dyno sheets and discussion for UK Rotaries!
Post by: J4P RX on February 21, 2004, 07:50:15 PM
Pretty sure its not wheelspin Iain.  Dyno Dynamics have a good repuatiton for not having problems with it.  You really can feel the 2nd turbo kick in so I believe the graph.

Brian, I guess it may well be because that was dynoed on a new engine.  It is running 1bar boost though.  Pretty high.  Im doing a dyno day in Crawley next month (just power run) so it will be interesting to see how it compares.

Brian,

The day next month I am doing is at Austec Racing in Crawley.

http://www.austec.co.uk/ (http://www.austec.co.uk/)

Its basically just a club dyno day with the SXOC, ut as I live there it would have been rude not to go!

Places are full, however I asked for two spaces - one for me and one for my mate Ben with his FD.  He will have an Apexi fitted and mapped by then though as he needs it to sort the car, so chances are he wont be bothered about the power run as he would get a figure from mapping the Apexi.

Ill ask him if he still wants this space bearing in mind the above.  Its MArch the 20th, and its £35.  Its only the normal club day power runs though, and not mapping etc.

Cheers
Lee

Rollin road junkie here:D

Went down to Abbey Motorsport today for a comparison and ended up with 346.5HP @ hubs that equates to 395@FW Flywheel torque 291.2.

Very impressed with their setup highly recommended for your tuning.

Title: DYNO DAY AT THOR ENGINEERING
Post by: gsb876 on March 27, 2004, 12:59:23 PM
Hello there chaps,

had a dyno read at Thor Engineering on the hub version where your wheels are off, supposed to be very accurate.

The result was 341bhp running at 0.75psi on low boost!!!
                         251 torque

Which for all concerned means if the car was run at 1.1bar we would make 450bhp people!!!

The next dyno day this will be proven, i did not run to full potential/boost as currently have a coolant leak somewhere and didn\'t want to over do it.

Funny thing was a R34 GTT apparently 400+bhp ran 342bhp at 1.3bar!!!:rollin :rollin :rollin

That\'s really good power Max,Things are hotting up for rotorstock!!
You should be seriously quick up the 1/4 now.
Considering that Clive had 355 at the hubs on the dyno hub at Abbey, you have currently got a lot more power than he had when he did the 12.2 1/4 mile, and with your wheels and Drag tyres you should be able to easily do a serious 11 second time up the strip if not a 10 with your caz diff.
What gear did you do your run on the rollers in?
Tim may be going up a week on sunday,maybe you could go too?
Kind regards

Well, the car appears quick, but is the driver up to the pressure - I guess that we\'ll soon find out!

Looks like Rotorstock will be major fun - with lots of cars now producing the goods :)

Rough spec of the car is as follows, probably missed a few bits!

Ported & polished, 2mm 2 pc Mazda seals, Garrett GT35/40 turbo, Apexi Power FC, datalogit, commander, SX fuel pressure regulator, 1300cc secondary injectors, electric water pump, Apexi GT front mount intercooler, air pump thrown in nearest bin, cat thrown in next bin, Greddy boost controller, NGK 10.5 racing plugs, magnecor plug leads, HKS twin power ignition amplifier, solid engine mounts, solid diff mounts, Kaaz 1.5 way LSD, Ceramic single plate clutch, Racing Beat springs, sway bars, Koni adjustable dampers, Porsche 993 turbo calipers and disks, Volk racing GT-7 18 inch alloys, Dunlop D01J r compound tyres, Feed rear box, Motec PLM lambda meter, Denso supra fuel pump, Bride bucket seat, Cusco carbon front strut brace, etc.

I vowed earlier today (with rotary witnesses) that I am now calling it quits in the pursuit of more power, so no more boost, enjoy the car as it is, it seems to like it\'s current state of tune. Any more work I do now will be purely reliability & tidying mods.

I shall take a peek at diary to see if I can go, should be a good giggle with Tim there to liven up proceedings!!

Water injection is not plumbed in fully yet (one of those jobs I keep meaning to finish).

Car is running one of my own maps at present, seems to like it as well. If it can stand 4 days of serious abuse, like it did at Nurburgring, then that\'s good enough for me!

Tony, I have no problems whatsoever with the 10.5 plugs :)

Geff - I always new Steve wasn\'t going sideways on purpose ;) it\'s just his heavy right foot :) When it rains, my heart pounds, Steve looks forward to it:)

Yeah, his car was totally different after going on the rollers. I drove it to and from CPL and the difference was very noticeable! Steve was happy - some thing like "**** yeah!" :)

There was a little downward boost \'blip\' right where peak power wouldve been (new boost controller not yet fitted), Guy reckoned it would see 340atw had the boost been maintained.

Steve\'s parting shot when he left last night was some thing along the lines of "what d\'ya reckon about 1.2bar then mate?" :rollin

Carl & Ant have worked there magic and got an extra 70 bhp out of my baby.

Please put me at the top of this list as my car with its itsy bitsy to4e made 365 bhp at abbey, at the hubs, and 298 lbs of torque.

Stunning power figures Gary - congrats to you and carl/ant.

On a different note I spoke to Pip @ WGT yesterday about de-catting and mapping my car and mentioned the power figures from the FDUK rr day @ g-force.

His response to their 240 RWHP figure from the car he rebuilt for me last year was "I didn\'t know I was that good".  His opinion is that they\'re reading some 20-30 HP higher than reality considering the only mod I have is street-porting on the rebuild!

Will be interesting to see what de-cat/mapping do for it!

Post by: g11ary on April 29, 2004, 02:28:31 PM
It was mapped to 1.1 bar I believe, I was not there but that is what my high boost setting is set to. Would go higher boost but will need to pull the engine and get Carl to breath some of his magic over it and dowl it.

It must be pretty close to its limits I would have thought. Anyone know what a t04e\'s optium boost is?
Title: Dyno sheets and discussion for UK Rotaries!
Post by: maximtaylor on April 29, 2004, 02:41:58 PM
You weren\'t there? Sorry should have said well done Gary, Carl and Ant!!

I have a similar problem to you Gary, in that I\'m going to have to get mine dowelled.

I\'m thinking of getting a 2nd engine built to spec. That way, I\'ll always have a spare should something untoward happen.

Or I could just up the boost and wait for something to give ;)

Nearly forgot, I did say last week that I wouldn\'t be after any more power :rollin

No it was Chloe\'s birthday, so now have 2 blisters from the shopping trip to London.
Should have gone to the rolling road, would have saved me the cost of 2 dowled engines :rollin

nice one Gary:D :D
That\'s some serious power from a to4e
What size turbine housing you got on there ? I thought it was a 0.81 a/r? If so I think it\'s being pushed to or very near it\'s limits at 1.1 bar.

Yes cant imagine they being much more to come out of her, by the time I start looking at bigger housings I may just go bigger turbo, which I say I wont go down that route as if I get the black car finished then the yellow car wont be a fast drive anymore. Will prob not start changing turbos just improve what I have on there, dowled, ported more, etc.

Great power reading Gary, well done to all that had a hand in achieving such large powers with a small (ish) turbo. Just think what the black beast will pull once it is up and running properly, and yes it will be up and running properly soon, have faith:D

431.4hp at the rear wheels, made at 16psi.

Built and tuned from scratch by Geff. Same T04 hybrid as used on the bridgeport if any one recalls i.e. not very big.

Using the John Yorke school of conversion that\'s APPROX 526fly and 462hubs. Off tut pub now...

It\'s ported un stuff :) Needs a bigger turbo but thats not going to happen.

Have only driven it at .5-.7bar (promised as it wasnt mapped and didnt have boost control - man i was well behaved - had two NSX\'s and a Carrera RS go by within 15 seconds of each other on the M4! :reallymad) but it felt \'lively\' as, should get a go again soon with a bit of luck. It doesnt like no load cruising that much a bit like the bridge. It seemed a lot more lively low down in comparison. The turbo seemed to be making boost pretty easily whereas the bridgeport made it late in the rev range. I guess it generally behaves how you\'d expect a big non-bridged engine to behave, kind of some where in the middle :)

Meant to be going to Avon, should be interesting to see how the gaff compares to Pod, eh...

Hello and welcome to the club,it is Guy I presume?Nice to see you posting on here.
I heard that you did an 11.48 in Geffs beast,well done for that.
I know you have driven quicker cars but it does go to show how hard it is to do a good time and experience is always a help.

So is Geff now putting on a bigger turbo?
We all want to see a 10 in a rotary soon!

I guess that those Hoosier\'s must have helped times over the Bridge port engine that ran on the Dunlops?And the charge cooler must have been helpful to the new engine as well.

Anyway,well done Geff,keep it up your nearly there for a 10!Watch out for Tim and Ross though!

Kind regards
Carl

My mistake, i humbly apologise, 312bhp at the f/w,  254bhp at wheels, i was misinformed.  still not to bad. got the graphs and figures last night.

310 ft/lbs torque.

Turns out the engine peaked at 6050rpm, he says the turbo light on the defi guage came on and the bhp stopped rising.

am i right in thinking that my fd should have 250 at the f/w ???

The bloke who did it doesnt know alot about rx\'s, just got it\'s power output, i think it needs to go to a pro rx garage to unleash more power.

On the table at the front of this thread are those figures f/w or r/w??

Hi All,

As the Dyno Results has now turned into a
\'\'The my Dads bigger than your Dad RR thread !\'\'
and l see it is now serving no useful purpose l have now moved the \'\'chat \'\' side of this thread to \'\'chit chat\'\' before it gets too out of hand !.

l think personally the only additions to this thread should be with RR Graphs as proof of results .

But sadly all this banter has probably confused a lot of guys and l hope they don\'t start thinking, why bother with any RR if these guys are saying they are all wrong.

Lets hope they all still realise the primary reason for going on a RR is to stop your Rotary from becomeing a grenade !!!!!!!


I have found this all a bit amusing though as it has taken me back to the many times l have stood in the pits and heard, \'\' so and so now has x HP\'\' and l have gone to the grid a little worried about so and so because they may have more HP than me !, but then when the race starts and l left them behind l then realise a lot of it must have been \'\'bar talk\'\'
Also many a time l have had people say to me over the years, \'\'I\'m going to blow yer doors off\'\' but as they say,

\'\' When the flag drops the Bullsh*t stops !!\'\'.

Fiddled on the dyno for a few hours yesterday, tweaked the timing and fuelling, kept it nice and rich and got the following.

Run at 0.95 bar, to help prolong engine life, it\'s quick enough!

Title: Dyno sheets and discussion for UK Rotaries!
Post by: gsb876 on January 13, 2005, 10:15:38 PM
I think their particular dyno can\'t handle speeds in 4th gear???
Title: Dyno sheets and discussion for UK Rotaries!
Post by: maximtaylor on January 13, 2005, 10:37:42 PM
Gear selection makes negligable difference to the power reading.

On the dyno dynamics rollers, \'ideal\' roller speed is up to around 100mph, hence 3rd gear.

Although 3rd gear generates more torque to the rollers than 4th, the computer knows the roller speed (which is obviously lower on a 3rd gear pull. Also, the computer controls the ramp rate, which means that a pull in 3rd takes as long as a pull in 4th.

The only variable that differs is resistance/losses through the transmission and tyres to the rollers. The difference between 3rd and 4th gear is negligable, 3 or 4 hp, if that!

I wanted to check the theory for my own reassurance, so I have checked this with several cars now, and the graphs were near identical, within 2 hp in all cases.

This means that our \'pub talk\' figures can\'t be fudged with different tyre and axle ratio combinations ;)

I have my \'old\' figures in that table. A few months ago I got Geff to slam in some 1300 secondaries and remap my Apexi. This was when he was mapping at CPL. Geff managed to get 306 rwhp at 14psi. This is a completely stock motor with seq. twins.

About a month later I went back to get a new clutch!!! LOL

I wonder if a slipping clutch made too much difference to the figures and mapping ?!?! hmmm......

Long story with mine,on its 2nd rebuild in 2000 miles.
Went pop on the rollers due to  injector problem last time, Geffs been good with the fix and helped in other area\'s so no complaints from me.

330 rwhp at .8 bar yesterday

On a T04R with loads of extra\'s, ill put a list at some point but last was a APEXI pfc and 1600 secondery\'s.
 
Keeping the boost down until water injection (dont want any more unplanned probs), which will be a couple of weeks. To be honist not really chasing hp now, just want to get as fast as i can now in set up and launch.

Just want to get in and drive, and yes it feels...fast, times will tell.

Some agreement on how the various dyno outputs should be converted to flywheel hp needs to be reached I guess i.e. how else do you list power at the wheels, hubs or fly in order?

Title: reliable conversion rwhp to ath to atf
Post by: petemillis on March 05, 2005, 11:08:13 PM
Most consistently reliable conversion factors I have found for a rear wheel drive are as follows.

RWHP +10hp to arrive at ATH HP then take into account 12% loss from fly to hubs by dividing by 0.88.

So, 250 rwhp + 10 hp  = 260 ath hp
      260/0.88 = 295 atf hp

Going the other way 295 atf hp - 12% = 260 ath hp
260 ath hp - 10 hp = 250 rwhp

how the heck are we doing this then as all the nobles figures are at the flywheel which when i asked was calculated from the -ve figures to calculate transmission losses or such like & basically thats only figure given which at first glance the figures so far are ATRW?

Title: Dyno sheets and discussion for UK Rotaries!
Post by: petemillis on March 07, 2005, 10:32:01 AM
How about 3 columns for horsepower:
1. ATF hp
2. ATH hp
3. RWHP
And if someone has indicated an ATF hp figure, then they need to show how this was derived from ATH or RWHP (unless of course the engine was out and put on an engine dyno).

I\'m guessing not many have tested on an engine dyno, so it might be an idea if everybody just quoted their RWHP or ATH hp (RWHP + 10), and then a single conversion factor for all readings to estimate ATF hp
i.e. assuming 12% trans loss from fly to hub, the estimated ATF hp would be: (RWHP + 10hp)/(1 - 0.12)        

The divider (1 - 0.12) is (1 - 12%) so assuming an ATF hp figure of 100 hp, subtracting 12% for trans loss gives 88 hp ATH. To add that loss onto the ATH figure you need to divide 88 hp by (1 - 12%), i.e 88hp/(1 - 0.12) = 88hp/0.88 = 100hp. I\'ve seen people adding 12% to 88hp in which case you only arrive at 98.6 ATF hp. at

but as mentionned previously all we have from the Nobles RR day is ATF & i\'d rather rely on there accurate figures (yeah thought i\'d start a dyno accuracy debate with that wording ;) lol) rather than just using a standard theory/formula to work out RWHP possibly with more inaccurracies......

Correct me if I\'m wrong, but surely Noble\'s only came to your figure by using a standard theory/formula.

Perhaps someone should find out \'what\' formula they used? (unless I\'m talking out my botty, and they use the run-down method).

they told me the figures were using the -ve load kinda thing which i presume is the "run-down" method & that they couldn\'t caluclate it back with a standard formula as they vary from car to car. Seemed a little weird they couldn\'t just whack the actual power at rollers on too but hey only going on what i was told & i still like my lill graph either way.....

Windows software - hope the IT geeks arent reading this! :rollin DD will soon be susceptible  to the Windows patented \'blue screen of death\' too as they have Windows software being finalised atm. Hopefully it wont be a compulsory \'upgrade\'! ;-)

Every one has a preference I guess, Geff and Phil have used Abbey and CPL more than most here and decided the Dyno Dynamics was theirs. Geff was introduced to the DD when he went to Aus with MicroTech in 2003 and was very impressed. He used Jon at RX Engineerings Dyno Dynamics. Either way, a dyno is a very useful tool to have in your workshop as you say Carl...

Other people who use Dyno Dynamics (extracted from our website) just for the sake of it:

Maztech
Mazfix
Dalton Automotive
Dyson Rotary
Rotormaster
Selectmaz

Be very happy if we get any where near replicating any of those guys achievements in the future, LOL!

Gary - no offense - I\'m sure a few of the entries are wrong! I\'ve moved you back up to numero 5. The reason Gurj is their with FWHP is that no one seems to want to agree on a conversion factor between W/F/H power - so I just listed them \'as recorded\' and indicated whehter W/F/H...
Title: Dyno sheets and discussion for UK Rotaries!
Post by: sdminus on March 12, 2005, 12:25:41 AM
It all looks very good but weather its fly or wheel seems irrevant really. It should all be on a even keel either fly or wheel not both. Also i would think that dyno figures should be backed up with accurate graphs from calibrated dynos to count.

May well be wrong but just my feelings.
Title: Dyno sheets and discussion for UK Rotaries!
Post by: g11ary on March 12, 2005, 12:41:43 AM
can see where the confusion is, I think Glen converted my hubs to wheels as I think thats what he wanted to get to, now is a mixture, fly obviously lower thats why I noticed it. Regardless of conversion factor if its wrong everyones would be wrong by the same amount but should probably convert everything to fly as must use it (and its bigger)

I think all figures on  here have been provided by sheets via the owners or the tuning companies doing them.

Post by: PETE SMITH on March 12, 2005, 12:51:49 AM
"dyno-dynamics" and "Flywheel" seem popular-converting the rolling road "at the wheel" to "flywheel" seems ultra simple if you\'ve got the right equipment.
Though i agree boost bar IS a major factor when comparing RXy\'s.

Title: Dyno sheets and discussion for UK Rotaries!
Post by: 20B_boy on March 12, 2005, 01:04:06 AM
Its easy to just use a deemed loss to convert from wheel to fly (for e.g.) - its a matter of agreeing what the conversion is tho or half those on the forum will be unhappy - you lot decide! We used to use a fixed 18% loss to convert from wheels to fly power, but that may or may not be accurate (unlikely) - and for a fact some will disagree strongly. You\'ll find umpteen different opinions as to how wheel/whatever power etc relates fly/whatever power.

Far be it from me to decide whats \'right\'.
Title: Dyno sheets and discussion for UK Rotaries!
Post by: PETE SMITH on March 12, 2005, 01:16:59 AM
IMHO,
It\'s fairly clear from the list that the significant factors seem to be:
1-whether it\'s ported
2-Is it a Phallic Toe-HKS or maybe the BB Garrett?
3-Non sequential Twins have a part too
4-If your Rexy is for straight 1/4 mile burn\'s, reliability is less of an issue
Unlike piston/conrod/cam non rotary engines, the reasons for differences in performance is simpler to see.
Maybe i\'m talkin a load of testicles:D :rolleyes:

Rich, you are the number cruncher.
can the sums above be worked out into a percentage, or just use whats a simple calculation like this one if it is the accurate.

Then can we all argree that figures to be quoted are fly.

If others disagree later, well tough you could change things constantly, were not looking for accurate we want something comparable. The other important items also that Pete put forward such as porting, psi, turbos etc can also be added .

At the end of the day it should be more fun than anything else.

The biggest bhp may rebuild every race, but bhp blown up on the dyno dont count, it must at least drive home or somewhere. Its all pub talk (where\'s danny when you want him)

Hey Pete!

HKS turbos are Garretts - but with housing profiles and designs and wheel combinations that are proprietary to HKS i.e. Garrett cant make them for others. Note that some HKS turbos ARE ball bearing too, in spite of the fact that most people assume they all still use bush bearing technology.

The main performance factors are the same with pistons and rotors - port shape on a rotor is the equivalent to cam shaft profile on a boinger for e.g.

Hi Carl

Both runs were in 3rd gear
Revs were more or less the same peak power was approx 7200 both power runs finished soon after that, no more than 8k
Both tests were within the same week, unfortunatly I have to work in between times;)
The car had the same fuel [Optimax]
Apart from having the dyno machines side by side I think that is about as close as you will get, as a comparison.

Makes pretty much zero difference on the Dyno Dynamics - does it change much on the hub dyno then?

I remember Guy had an R32 on his dyno which was then taken to Abbey the same day - a similiar rollers/hub variance to that which John saw fwiw.

Post by: jonyb on April 04, 2005, 10:01:31 AM
Had a good drive up to Thor at Warwick Saturday (2 April) with me local Jap car club.

Having run me motor in and already having a Dyno figure from Geff @ReWorx, was really for a day out and check up  to make all was ok.
Anyway, final figure turned out at 379hp on the hubs, was a little shocked as had been 323rwhp at Geff\'s.

Anyway, final figure turned out at 379hp on the hubs, was a little shocked as had been 323rwhp at Geff\'s.

Yes dynos do read differently.
I went to TDI the other day and the use a hub dyno,they reckon that there readings are 7% less than the one at Abbey.They are both different makes.
That is why I have said many many times that dyno\'s are only a tool to tune your car, and for consistancy in tuning you should try to use not only the same make of dyno but the exact same one if at all possible when making changes and tuning again.
All dyno figures should be taken with a pinch of salt.

Why did u do that Carl? is it hard to load cars up on the hub dyno then? cant think why you would need 170mph road speed to generate adequate load whilst tuning - or were u just testing out Dave\'s silly-big brakes? :rollin

Well your car should be reliable since it has been mapped at ReWorx.
The reason that we map to a high speed should be pretty obvious really,the car is not limited to only 120mph so the tuning should be done at the limits of the car and not the dyno whatever the hp you require.After all,how many people only drive their car to the redline in 3rd gear?especially on track days.

The dyno hub puts plenty of load on the engine but enables all of the gears to be properly tuned,if the engine is only tuned in 3rd gear then the turbo will come on boost differently from 4th and 5th and in those gears the tune may not be as safe,But I would have thought that any good tuner would know that.

But remember that the 280hp is the agreed limit from the japanese manufacturers,so in all likelyhood the spirit has more than 280 flywheel.
Andrews car is on a stock ecu still too.

In case it isnt evident I dont do any tuning for RE:Worx! :confused:

Carl,

I dont see how road speed correlates to load and thus why you need to tune maximum load at 170mph. My understanding is this (ltd I grant u!): the ECU determines ignition and fuel settings at any given time by looking up the current engine load (which it uses the MAP sensor to measure) and referencing it to engine rpm. How does the amount of timing or fuel required at a certain engine load vary with road speed? isnt the timing and fuel the same for a given load, whether you are in 2nd or 5th? the boost pattern will vary loads but the ecu will look at the same values in the MAP to determine what it does - theres no gear or road speed correction? so what does it matter which gear u tune in as long as all your loads sites are covered - which they will be - ? I\'m confused. I will ask Max later, I\'m sorry if I\'m missing some thing.

Hopefully some one else finds this interesting too!

Hi Rich,
Load points in 4th gear will differ to load points in 5th gear, same as the difference between 3rd and 4th. Part of this is due to the time difference taken to cover the effective rpm range, and the amount of load asserted over the same area.
For instance, say an engine´s peak torque is found to be at 6000rpm. Peak torque being the highest load point, and most probable point for detonation. As the engine accelerates through this point, a tuner might not notice an increase in Knock or hiccups in fueling. If he were to tune the car in a higher gear, the time spent over this range will increase thus improving the chances of tuning out any anomolies.
The tuner may wish to hold the dyno load at this point to simulate this effect in a lower gear, but ultimately will not give a true representation of the load characteristics experianced in the higher gear. Chassis dynos should be used to suppliment ones tuning methods, not determine them.
Most common enviroments for tip failure are on the road and in the higher gears, accelerating through the engine´s peak load point.
Sorry for the long winded reply, i hope that it may be of some help.

John

It is,don\'t worry.

See what John has said.
Thanks John for explaining the reasoning.Also if you map only in one gear then you are likely to end up with parts of the map that have not been tuned,eg a high gear at low rpm will end up in a part of the map that a mid gear will not.You still have to input the data to control the event correctly so that when the ecu detects those parameters it knows exactly what to do.

Yup, just found this thread. I agree that the longer you spend going through a cell, the greater degree of finesse you can apply. A/F correlation to the cells in question is more accurate, and so is the volume of information you get in feedback.

The cells you pass through also vary slightly, a slower pull goes through into boost cells far earlier than a regular shootout power run, although once you hit the peak average boost cells, the journey across the rev range is as before.

This can be mimicked on many dyno\'s by adjusting the ramp rate manually, effectively giving the same slow rate of acceleration and loading that a higher gear would give. Two ways of reaching the same result.

Good cooling fans are a necessity for this!!! The extra load turns the rotary engine into a very effective kettle ;)

Off to play fireman now, cheerio!

Post by: MikeLMR on April 04, 2005, 09:04:40 PM
how do these different types of dyno\'s work then ?

I know some use a rotating mass and just work it out by how quickly it can be accelerated but then I imagine thats not the best thing for actually mapping an engine ?

I\'m not 100% sure but the  water brakes we use at work vary the load to hold the engine at a constant speed and calcuate the power from that.

And how do you calibrate a rolling road ? I can see how you can make sure the rotating mass ones a pretty much spot on by making the flywheel arrangment accurately but the brake type would require somthing of know power output to calibrate it ???
Title: Dyno sheets and discussion for UK Rotaries!

The dyno dynamics type uses a system similar to a Telma (electromagnetic retarder) on a LGV Mike.

How it is initially calibrated, I\'ll find out.

I think the Dynapak uses fluid?

So do all the DD\'s have the same limitations or are the big boys using bigger better DD\'s.

Is that like comparing it to a folk lift, and a ramp
both will lift the car, only one better and possible without damage.

Hi Max,
The type I used the other day works similarly to the DD,but there is no "flywheel effect" from the weight of the rollers themselves that can affect the way that the rollers act upon the rest of the car when going through the gears.Of course when holding a point then that will alleviate that.

Hey Rich,
Come on,I am sure that you know how your equipment operates,and don\'t need Max to explain it on here since he is working for you.

Hi Gary :)

I think most of the Rolling Roads available now are far more advanced than people think, especially if the operator knows how to use them properly! The big leap was the addition of the computer to the system.

Most dyno\'s can hold / retard / ramp / display and store all manner of parameters / make the tea these days.

I guess as with all things, people have preferences to makes and types.

265RW/HP  @ 0.8 Bar  (i think, or was it .9 max?)

The car is now smoother than baileys on ice  :D :D

And by the way the fuel economy has gone through the roof, it cost me twice as much to get there in the morning pootling along, as it did thrashing her all the way home.!!

Thanks to Chris and Geoff for the friendly and no messing about service, they found a couple of problems, and just got on and fixed them.

Thanks to Max for the setup and the demonstartion on how to fill a workshop with smoke!!!   I will let you explain Max.

the results i got are as follows:

199.3hp ATW
237.6hp ATF

the point the second turbo kicked in the fuelling went off the scale past 10:1 afr
Primary turbo peaked at 0.75bar secondary hit 0.69bar before dropping down to 0.6bar

Quote from: ro284Oh i do like that Richard, it gives a good guide as to what mods does what, i think that would be enough power for me in fact,
is it enough for you?
cheers Bob


Thanks Bob :cheers

Its enough for now!! Need to concentrate on cooling and suspension over the next few months, before I increase the power anymore! :evillaugh

I think the only thing i will do differently is to fit a silinced mid pipe, to keep the nieghbours happy! plus im getting on a bit!  i was hoping to see/ hear your car on sunday but think you said you can\'t make it till very late in the day, Are you going to lower it? I just had new pillow bushes (rear) fitted at Tim\'s, that made a difference!

Yeah have to work every Sunday :reallymad , it\'s very difficult to get days swapped etc.
Hoping to catch people later on, I know some are heading over to Dan\'s to strip his car of bits! If not Im sure we\'ll meet at shows next year!?

Suspension wise, starting with the basis- laser alignment as the car is suffering abit of bump steer. :(
 Uprate antiroll bars, braces, etc. Will eventually fit coilovers, may lower alittle, but not much-  roads are to poor round here :reallymad .
A FEED full bush set would also be v.nice ;)  :yes  :yes  but too many penny\'s at the mo :rolleyes:

QuoteSuspension wise, starting with the basis- laser alignment as the car is suffering abit of bump steer. :(


Start with alignment by all means, but bump steer on a lowered car with skinny tyres is a feature, not a bug, and means your suspension is working properly! Bump steer will get WORSE as you add braces and so on. Suspension\'s supposed to follow the surface exactly to provide grip, but usually they engineer in a bit of slack for comfort, which what mops up the bump steer (along with the chassis warping.)

Understand that mate, thanks anyway! :)
At the moment the car is totally standard suspension wise and not hugely skinny tyres and suffers bump steer badly, skittisk(?, is that a word) on counrty roads, etc. So I know something isnt aligned quite right.

My last car had very low profile tyres (25\'s) and lowered to within a inch of its life (mostly done for looks, as it was SLOW).

So have a good idea what it should feel like, the RX in comparison is very unpredictable.

May also be a case that bushes are on there way out, after all the car is 13yrs old!

Hope to not get shot down in flames :flamed  :rollin

Tricky,

mines is the same, and as far as i can gather its usual in all rex\'s. Ive changed my rear bushes which does make the car feel better, i still get alot of bump steer. i live in the country where the roads are bloody awfull, im running std. sus with 255/45/17 rear    235/45/17 fronts.

its a part of rex life i am afraid, (alot has to do with your roads though)

Not too bothered as the figure will be improved early next year, but my car made 342hp @ hubs @ 0.6bar.

t78 turbo 13b

Dont matter too much but not sure if all figures are in rwhp or flywheel hp ?

Looking to run 1.2bar next year with some extra mods like water inj and bigger injectors / fuel pump so will be interesting, will it be going up the strip /??????? ewrrrr ................ no  :D

If there is a forum agreement on a reasonable conversion between whp, fwhp and hhp then I will up date the table now and keep on top of it if no one else wants to - but if some one else (with HTML abilities!) wants to please do so as its a tedious process to up date without adequate coding skills i.e. using an editor then removing all the unwanted spaces...

Title: Dyno sheets and discussion for UK Rotaries!
Post by: 20B_boy on November 03, 2005, 02:54:03 PM
Thats fine Brett, but some people will only have readings at hubs or flywheel - which thus need to be converted to whp using an agreed (best guess) conversion factor - which is where people have different views...

Post by: kevint on November 03, 2005, 03:11:53 PM
Hi Rich,

Great that you have offered to keep the table up to date. We won\'t get consensus on how to convert to a common measure so given you have volunteered why don\'t you just use the method you think is reasonable and you are happy working with.

So long as the method is clear and the table continues to include the original figures and where/how measured then if others want to interpret differently they have the base data.

Cheers

Kevin

Not quite right - we know how to do it but it\'s hell to maintain the inline HTML.  Takes a huge amount of time to just move an entry around.

It\'d probably be simpler to write something in code and run it of a database than edit the html each time!!!  My PHP\'s up to the task but I don\'t have the time.

A simple option would be to whack it all into a spreadsheet (e.g. excel) and then create an image from it and put that up.  Simple and quick.  Same with the 1/4 mile table.

Thoughts?

Best Power on Pump Gas is CJR.
No point having a column for the boost levels , cos 1 turbo flow at one BAR would be different to the flow rate of another turbo at 1 BAR.
Its all about PUB talk figures guys lol

I think we will just keep the table as an image so everyone can view even if there are in an internet cafe.

If the figures are out of date is up to the individual to post there new Dyno chart.

Mine was all done on pump gas at 1.1bar with WI... the injectors ran out of puff just below 7500rpm so could not go any further so may be bigger injectors and up that boost to 1.4 to see what she can do....but its good as it is... :cool
Title: Dyno sheets and discussion for UK Rotaries!
Post by: dre on March 09, 2006, 10:28:14 AM
BlitzBoy - I think boost should be included on the dyno table cos you list the turbo used so people are aware of how big/small the turbo is and how much air it can flow. If someone tells me they are running 500bhp atw with a T88-34D my next question would be, " what boost was that run at?"

Laeeq - i think you should defo uprate your injectors. with that extra bit of boost a reckon you\'d get close to 500atw  :Giggle

I got 252.8bhp at the hugs at WGT. Pip ran out of time but was still getting 86% duty on the injectors. He recommended i upgrade and go for colder plugs when i want more power. Still, it\'s not bad for my first ever tuning session.

Any chance this can be put on the table (Worked out at 298.3bhp at the fly....roughly! :p)

laeeq what injectors are you running?

Dre I will include a boost column for the next round of updates with the known values

nikp I will need you to post your dyno sheet on this thread for you to be included on the table these are the new rules, flywheel figures will not be recorded, only hub or wheel figures

Cheers

BB-- i dont have a clue what size they are? think may be Max or Jay know better...but was told they were uprated, also running on cold, 10.5 and 11 irridium plugs and 4" straight through pipe so probably that may also hove some thing to do with high figures....

About 0.85 - but went a bit wobbly by the time it got onto the second turbo. Will a boost controller help smooth it out?

Dont know if this will help, looking down the list:
No12 - I think Max is running 400+ @1+bar
No20 - Tim is QUITE a bit more :mmmm
No22 - Me - that engine is sitting in a garage so delete it please
No 35 - Robbie is running considerably more now after a re-build + re-map
No40 - I know Jay is now single, so not sure if this is relivent

John these figures on table are figures of History of Dyno runs,if people are running more power then its up to them to post up new dyno charts.

I know you are going to the Dyno on Sat John with your new configuration so Im looking forward to your new figures and dyno chart next week :)

I see the list as a kind of history of high power rx\'s, so if you hit the top spot and nobody beats it, even when the car is long gone you can say \'i had the most powerful rx in town\'.

My car is dead and buried but I would like the entry to stay in the list until I get a new one with more power, then it can be deleted, i think one entry per person should be a rule too.
Title: Dyno sheets and discussion for UK Rotaries!

Hmmm, not sure about this one-per-person... suppose I -had- bought an FC shed with Grinder and done something with it, I\'d want an entry for both cars!

In fact it\'s quite feasible Tim could have quickest FC and quickest 8, come to think of it...

All will be revieled :mmmm - not so much out and out power more to the point of USABLE power. ATM my 1.05 peak boost is at around 5k so, is a bit laggy till it gets going so, reducing the exhaust housing and increasing the the compressor to \'hopefully\' be able to introduce a bit more boost a bit earlier, will let you know over the weekend if the calculations match the application, hopefully I will be able to overlay before and after.

How\'s that!? Perhaps i need someone to explain more? but how can you have more losses at the hub, than from the wheel which is about 25cm away, and goes through no mechanical parts that will need to frictional losses!?  :xconfused

Ok, i have done a quick trip through the internet, and have identified that there is tyre resistance that adds another factor into the equation. Plus there are other unknowns that can occur, including tyre slippage.
Title: Dyno sheets and discussion for UK Rotaries!
Post by: antnicuk on March 10, 2006, 05:52:51 PM
i\'m back and clean now......

basically the more the engine has to turn before the reading is taken the more power is used up before it gets to the dyno.   it takes energy to turn componants, the more you have to turn the more power is taken.  Most people will quote the figure that the dyno produces (a.t.wheels or a.t.hubs) as there doesnt seem to be an accurate figure that the drive train uses (18% seems favorite for wheel power).

If you had a 50 ft long propshaft and 4 ft wheels you would see a much bigger drop in power than if you could attach the dyno to the back of the gearbox.

Um guess there\'s a chart going on somewhere but here\'s my dyno sheet anyway.. this is mapped on 95octane running 98octane with 1.1bar of boost no WI or charge cooler or silly shenanigans. Once i\'ve finished my work hoping for another 20rwhp and the girls to strip off and collapse at the roadside worshipping the car. Although will be happy with just getting it running again :)

I\'ll now go read up on the rules and find out this is a thread of coronation street or something.

Edit: HP in chart is ATW.

HKS Induction, Hard intercooler pipes, down pipe, dragon mid pipe & Blitz back box, air pump removed.
282BHP ATFly
240BHP ATHubs
Ran out of fuel at the top end (injectors maxing out) so max boost was turned down to approx 7.5psi
Pip commented on how strong my mid range was (which was nice)
Now needing uprated pump & 2x 1640cc secondaries (anyone)?

Title: Dyno sheets and discussion for UK Rotaries!
Post by: iaint on March 27, 2006, 09:55:48 PM
Mapped at re:worx by Max.  Max power was at 0.9bar.  We were aiming for 1bar but it wouldn\'t hold that on the dyno.  I\'ll make do until I go single :)

Interestingly the number is only 1bhp more than previously (and I\'ve added a lot to the car since then).  According to Geff this is due to a \'mistake\' in the way they were getting the intake temperature - post intercooler rather than at the air filters.  This meant that the dyno software applied a power correction to the figure boosting it artificially (Geff estimated that it\'s by as much as 20% depending on how effective the intercooler is).  Hopefully Re:Worx won;t mind me saying this and it really only applied to power figures where the intercooling was not effective!

As I was running very high intake temps before with the stock intercooler the correction was large!

I\'m happy and, even on low boost the pickup is more than scary.  Not had a chance to play in the dry yet so hopefully the weekend will see some decent weather and I can get to know the car again!

Hats off to Clive/Shy for the fabrication and fitting of the intercooler/rad - seems to really do the biz and looks cooool. :)

Quote from: antnicuksounds good john,   so whats changed....  come on spill it........... please

Wellll :D My old turbo made lots of power, but I could read war and peace waiting for the spool, pretty good for the strip not so good for track / fast street. So, it was a case of getting the ol girl to wake up a bit sooner and get enough air to pass through the compressor, after 2 attempts I think we are just about there. Basicly it now has a different compressor wheel [blade angle] and a smaller exhaust housing, dont think I should be putting out the sizes just yet as this was after some exhaustive testing and I would have to kill you once I had told you :eek: Biggest problem I have now is to get a better flowing backbox I think this is where my restriction is, so it will be down to trying a few out to get A] a good flow and B] be quiet enough so I dont have to wear cans whilst driving it, the power stearing mod seems to add about 10+bhp..........cheap mod that :2Confused
Oh and it red lines @ 9k, worth all effort that went into the build.

Can I be added to the chart :) Pip recently tuned the newly rebuilt engine at WGT,it was a tough decision whether to go single or stick with the twins as I love the response of the twins.Decided to go single with an HKS to4e,not the latest and greatest I know but it\'s a super little blower with good responce and great torque,just what I was after.

Anyway was really pleased with 340bhp@hubs on the new fast road ported engine.That figure was achieved with 0.8bar.

I did all the porting myself and got a lot of help from Judge Ito on the nopistons.com forum on the tuning. Now its in a 1977 Opel Kadett C Limousine. Much lighter car but still has the weak differential so I can\'t push my luck.

Had my old Turbo II dyno\'d at ReWorx on Monday 10th.  

The new turbo is working really well.  I am 6 BHP down on the last turbo.  Had 384 at the wheels and now got 378 atw but i have 110 bhp more at 4000 rpm.  and more torque at 3500 rpm than i had with the old turbo at 5000 rpm.  320 lb max torque now and it pulls through 7500 rpm.  (remember its a FC not FD)

I have compared my graph to some of the 450 plus bhp monsters and i had 100 hp more at 4000 rpm!  The power for a street car is superb and it was great on the track at Brands.  

The brakes wernt unfortunately but then the gravel stops you well!!! :2eek

Thanks to the ReWorx crew,  now lets see some good figures from the tripple! :Hammer  

I will post the graph when i can be arsed to wire up the scanner

Oh,  by the way, that was without NOS,  I wasnt brave enough, any one wanna buy a complete NOS kit, with all the extras and safety bits you will need, progessive controller, purge kit and full bottle etc!

the graph,

the little flat spot at 4500 rpm is the water injection coming in,  i will adjust it so it comes in a little later i think.

Its very similar to mine up until the 5k as mine keeps going up but still very good results and sound engine you got there.

Have you done all the engine work yourself???? very impresive...

Cheers gents,
i ported and built the engine myself and its still the original TII block with the series 4 low comp rotors.  The FD block is a little better for power and big porting is easier due to the lower inlet manifold size.  When its due a rebuild i will do more porting as i now know more and have lots more metal to remove.

Post by: antnicuk on April 13, 2006, 04:14:41 PM
i dont have a boost map but you can have a look at the computer while you are there if your interested.
The turbo is Eds old GT35/40 (non roller bearing) so nothing special but good for the job, its nice having very little lag for a change,  i only used 3rd gear around brands, i didnt need 2nd which was nice.

When is the essex meet, if its the 20th, i\'m working a late shift which is a shame.

John.. That looks really good. I cant imagine the differance that you would feel in that.

What blower is it out of interest. Im amazed at how linear the HP line is. Its almost on a 1:1 scale. Its hard to see on the pic where the tq and hp cross but i presume its on a auto scale. Is there any chance of a larger copy for reasearch porpose.....

Scott, its a hi-bred T4, I tried posting a bigger version but it would not let me, give us your e-mail I will forward you a bigger version. The difference is fantastic, the expected sweet spot for the turbo is about 1.4 -1.6bar this is at 1.15 :eek

Ant : Approx 330ftlbs ATW dont know if you do the 18% to get fly my guess is you do so that would make it about 390ftlbs

Title: 475atw= 400 per tonne
Post by: 88GT-R on August 07, 2006, 11:46:31 AM
Went up to WGT on Saterday for a map clean up. Did several runs with the following results.

Warm up run - 331ath on 0.58bar @ 6000
Clean up run - 363ath on 0.59bar @ 7000
                  - 383ath on 0.75bar @ 7300
                  - 394ath on 0.87bar @ 7300
                  - 403ath 0n 0.89bar @ 7300

I had to increase fuel slightly at 6500 to level the torque curve a bit, as it was still climbing. We have not found where the engine is making it\'s peak power, as the steel seals limits how high we can rev the engine. As the graph shows, power and torque are still climbing above 7300rpm!
I will put a few more miles on the engine, and might have a look at running over a bar.

As it stands at the moment, i have achieved my goal of building an FC to produce 400BHP per tonne. The car weighs in at just under 1200kg, with engine power at 475atw.

Saw several sevens in the workshop, Marks and Doms included. After mapping went to Oulten park to support Stacey Vickers and Dave Nixon. They won all their races, with Stacey busting a gearbox, giving us under 15 minutes to change it as well as refuel and re-tyre!

A good weekend, and many thanks to Pip.

The two set of thin lines on the graph are for the old 13BT engine running 0.75bar. The difference can be seen in how linear the power is now in comparison.

Make that a bit high, I did back to back tests a few years ago using CPL dyno dynamics RR and Abbeys hub dyno, same day about 3 hours inbetween tests. 317 RWHP and 348 hub HP so about 10% is a fair guess.

17% is the norm for Dyno Dynamics wheel dyno, I should have read Ants post correctly the 50hp differential between hubs and FWHP is pretty close, mind I dont know if that is accross the board.

The thing with dynos - they give you an indication of what power your engine has, the best thing to do is keep using the same machine be it hub or wheel to ensure continuity.

Where it gets confusing is when you start comparing the 2 and trying to work out the differences:2Confused

Agree with you there John, if you are doing loads of mods then you need to use the same Dyno method to see exactly what your gains are as 2 different ones will show seperate figures for your mods. :)

I\'m new to the forum and I\'ve been looking through the dyno sheets thread, I\'ve looked at a few of WGT\'s dyno sheets can you tell me what\'s going on with the lb/ft torque side of the sheet is the trace for something else?

I see JamesFD3 is the same, what\'s going on?
I\'m taking my standard FD to Pip\'s next week for compressions & power run to see how much life is left in it as I\'ve had it 6 years with almost no trouble.

Hi brian yes very pleased more to come when wastegate sorted to remove excess gases and additional injectors fitted. better asking pip about torque graphs too techy for me got 4 printouts all together all i inderstand is bhp !!!!!!!!! ,great bloke.hope compression test is good mine was done in february 8.4 fronts 8.3 rears :D  .fairly new to MRC as well had EVO\'s upto march- good luck

Pete,
 
I\'ve been to WGT this morning so I asked about the torque side of the graph, it\'s at the wheels before correcting for gearing. See below for comparasion
 
Compressions not bad but not good either with 63000 indicated, it would have been better if the rpm\'s had been a bit higher.
 
Front @ 231 rpm      Rear @ 220 rpm
 
6.65                  6.25
6.70                  6.20
6.45                  6.15

201 bhp @5600rpm at hubs approx 237 at flywheel not boosting too well at higher levels starting to tail off above 5600-5700. So room for improvement.

Brian

Hi Pete,

Try and improve boost on secondary for a start, looking at a rebuild over the winter I suppose.

I\'ll be interested in people\'s comments on the boost on second turbo, constriction from standard air box & exhaust perhaps, but I would have thought second turbo not well. Not that I know anything.

Cheers

Brian

What did Pip have to say about it? What was his thoughts?

The boost looks good, the build up on the second though looks slow and lazy. When i first took my FD to pip last year, it first produced 150bhp at the wheels. Then he got it to 200bhp, then finally 226bhp! (More or less standard bhp at wheels)
Title: Dyno sheets and discussion for UK Rotaries!
Post by: Brib on September 07, 2006, 03:58:36 PM
Pip, said constriction of standard air box & exhaust maybe running out of air, I\'ve got a uk back box on.

Like you say it doesn\'t look like it\'s as happy as it could be, hence not making any power over 5600 rpm, still it\'s not all bad news, when it\'s sorted it should go a bit better.

My dyno results from today - a little bit lower than expected, but haven\'t really started on the engine yet.
 
Mods (performance affecting) to date are Racing Beat Exhaust
HKS Mushroom
Blitz Acces Chipped ECU (tuned for exhaust and intake)
 
First pic is HP against boost curve, 2nd pic is HP against Torque
 
(Flywheel figures)
 
I will post updated dyno sheets once the new turbo, injectors, eManage and boost controller are on.

218 at the fly - so you are looking at a 16 bhp increase over stock

i would have thought that the exhaust and filter would have gained you a lot more

and how come its only boosting at .5/.6 ??? how have you clamped it at that ????

is the exhaust fully decatted - you should be getting .8 if it is ??

might have to get mine on the rollers before i start playing :D

Exhaust will make a gain, the heat soak from the induction kit might make it loose power and power will also depend on how good the compression is.

I think a lot of problems lie with the turbo now - the car was making good boost (about 11-12 PSI), but with the stock ECU it was running lean.  Rotechnicks worked on the boost issue and managed to get it back to stock levels -  8-9 PSI, and I put the aftermarket ECU on to control the creep and correct the fuelling.  The car is reliable now, but has lost some power.  I could put the boost controller on and get back about 50 BHP, but the turbo is leaking oil into the charge now, and I suspect is not long for this world, pushing the boost up is only going to hasten it\'s demise.
 
When the new turbo arrives, I will get that on and then we\'ll see what it can do.  Will run it on spring only to start with, as it\'s a bigger front end anyway it should be similar to what I have now, and that\'s a good place to work from.  Emanage will go on, but only setup to read to start with, and I can then get some baseline figures before going mental with mapping.
 
Can\'t wait for this thing to turn up now !:3gears-rh

Not too bothered Brett - when the new tubby comes it will definetely be going up.  Just need the old turbo to last until then.

Just been sorting out some silicon hosing, and shiny metal pipe for a modified inlet duct - going to get rid of that hideous double 90 degree bend and just have a single 45 degree in it.

Impressive figures John - what do you reckon it will rev to ?

She will rev round to 8, but i would rather do that on another day!! The steel seals are the limiting factor. I reckon the engine is producing peak power between 7800 and 8200. Without increasing the boost, there should be another 20-35atw to be had.

Hi Jurgen :)

The engine was built by Carl Hayward and mapped by Pip.  When the engine was rebuilt it had:
New Rotor housings
New side housings (Plates)
Good but used rotors
3mm Apex Seals
Competition Bearings
Race clearanced eccentric shaft
Major extend port
Dowelled

The engine was also balanced at build time

I must say big thanks to both Carl Hayward and Pip for their work which has been spot on.  Helpful & Friendly every time and always a good cup of tea at either workshop :)  Thanks guys!

The turbo is a Turbonetics T60-1 with an .84 hot side a/r and .70 intake mounted on a HKS cast manifold. 550/1600 Injectors managed by a good old Apexi PFC at the moment with a dual SBC handling the boost.  I\'ve also got a V-Mount intercooler setup and a HKS Twin Power Module.

Attached a pic of the engine bay.

I like your car, hopefully mine will look that good one day... (got the same rear bumper - not fitted it yet tho)

thats very impressive for a very small 0.86 exhaust housing,   and suprisingly laggy looking at the graph.  125 bhp at 4000rpm,   Nice smooth power though, what boost is that running?
Title: Dyno sheets and discussion for UK Rotaries!
Post by: monkey-fd3s on December 07, 2006, 11:43:18 AM
Hey Antnicuk

It\'s running 14.65PSi of boost not going to push it any further than that at the moment.  

Yeah the mid range is a little missing but I compared Jurgen\'s graph to mine and I make a little more power down low same in the middle and just a touch more at the top end.

I\'ve got my solution to improve the midrange already... looks a little like this
Title: Dyno sheets and discussion for UK Rotaries!
Post by: antnicuk on December 07, 2006, 11:48:20 AM
I think just about any high power rotary has that little bit missing in middle (unless bridges) but they make up for it at the top.  I bet it feels great on the road, especially with that small amount of boost.

Still amazed you got that much power through a 0.86 housing.  Must have a large turbine wheel.

Can anyone explain Pips graphs,  whats the difference between the yellow and the green reading?
is it 419 at the hubs or 434 at the hubs?
Title: Dyno sheets and discussion for UK Rotaries!
Post by: monkey-fd3s on December 07, 2006, 12:01:47 PM
According to Pip it\'s 434 at the hubs and the other graphs show the 503 fly wheel figure.  

Strangely the turbo that came off (HKS T04R .96 A/R) was a lot "slimmer" this turbo is more has less height from flange to centre of turbine wheel but tis fat... so fat we had to notch the chassis leg into an L shape in order to get it to fit and re-profile the suspension mounts.

It does feel nice but it\'s the wrong time of year to be giving it hell :(

At the Thor dyno day in may there was a couple of cars that been dyno\'d at both Reworx and Pips and the Reworx figures where slightly higher than the hub dyno figures from Pips/Thor when compared. The WGT, Thor figures where very similar but they do use the same type of dyno so this would be expected.

Kev the reason the diff between thor , wgt and re:worx figures would be down to reading at the hubs and atw figures do come out pretty close when calc is put in for corrections.
Ross which version software are you using the 3.4 is a real so and so. But 3.3 it great to use, pity we didn\'t realise the nos was not working at the time:)

I know:)

Without keeping on repeating myself [and yes I know you can not use one example as the be all and end all, but, I think it gives a clear indication] hubs as a rule give something like a 10% higher reading than a Wheel dyno, so if you have a 300atw reading this will be roughly 330ath or 352ish as a f/w reading or as Ross has said the 1/4 terminal is the defining power output. Where is Glen when you need him, he put up somewhere a comparision between horsepower and terminal speeds
Title: Dyno sheets and discussion for UK Rotaries!
Post by: Carl on December 08, 2006, 08:32:25 AM
What is quite comical is that hub dyno\'s are also giving LOWER readings in some cases than wheel driven dyno\'s ones.
That is what Kev is saying too.

Hi all, John - just happened to catch this (so many emails coming in these days!).
 
Some of the online calculators out there are very good - and generally speaking, ET\'s/MPH\'s can be calculated by mathematics of course.
 
To run x mph, with x conditions (Air Temp/Humidity), with x weight, x tyre width/height (traction), x gearbox ratios, x final drive ratio, and of course x hp.  Obviously x ET will change due to traction conditions, and gear selection, etc. etc.  
 
Simply though, you can just look at the Weight with HP to make calcs.
 
You have to be as accurate as possible with weight, don\'t kid yourself - add everything like how much fuel in tank, driver weight, are they standard wheels? Roll cage? etc..
 
Standard Series 8 FD (Type R = 1260kgs which is 2777lbs)
Driver: 75kgs = 165lbs
Fuel: 40 litres = 40kgs = 88lbs    (roughly 1kg per litre)
 
Approx Total: 1375kg = 3030.5lbs
 
This is pretty cool: http://www.speedworldmotorplex.com/calc.htm (http://www.speedworldmotorplex.com/calc.htm)

Th ET calculator is saying 337 & 398 whic is more likely as i only running one bar, so something is not very accurate some where.

Quote from: monkey-fd3sHi Jurgen :)

The engine was built by Carl Hayward and mapped by Pip.  When the engine was rebuilt it had:
New Rotor housings
New side housings (Plates)
Good but used rotors
3mm Apex Seals
Competition Bearings
Race clearanced eccentric shaft
Major extend port
Dowelled

The engine was also balanced at build time

I must say big thanks to both Carl Hayward and Pip for their work which has been spot on.  Helpful & Friendly every time and a:3gears-rh lways a good cup of tea at either workshop :)  Thanks guys!

The turbo is a Turbonetics T60-1 with an .84 hot side a/r and .70 intake mounted on a HKS cast manifold. 550/1600 Injectors managed by a good old Apexi PFC at the moment with a dual SBC handling the boost.  I\'ve also got a V-Mount intercooler setup and a HKS Twin Power Module.

Attached a pic of the engine bay.

I like your car, hopefully mine will look that good one day... (got the same rear bumper - not fitted it yet tho)
:3gears-rh  nice mate

Will have to meet up some time Spen and Ricco, haven\'t spoke to you for a while.
I\'m well pleased with Pip\'s work. On the graph at about 4250rpm there is an increase of 100bhp compared to the previous map! I know the cat is restrictive, but I didn\'t know by that much! Boost comes on much earlier as well, although I haven\'t driven it yet with the high boost setting cos I\'m too much of a wuss in this weather. :p

Comes in at 5000 revs and I change up at 8500 revs. But to be honest anything I have played with prior to this upgrade has been history before I get a chance to change into 4th gear. So that will be sooner now.:InLove

Can you add me to the list please

The car made 333rwhp @6500 rpm at WGT today :D  (393 fwhp) :Thumbs-up

The torque has confused me though - it\'s 317 ft/lb at the fly, and 1103.9 at the wheels :o  All at .9bar.  Didn\'t notice till I got home.  Might have to get Pip to check that for me.

The car was loosing quite a bit of power due to boost spike!  It\'s mapped to be safe, but I\'m loosing upto 50hp in the mid range and a possible 30hp on top :(   I need to take my turbos off and send them up to Pip so I can have the wastegate enlarged a bit more... apparently my engine builder is too good :Thumbsup!

I\'ll post my sheet when I go into work on Monday.

Chris
Title: Dyno sheets and discussion for UK Rotaries!
Post by: MikeLMR on March 10, 2007, 07:23:13 PM
torque is multiplied by gear ratios in the gearbox and diff, whereas power remains unchanged by the ratio and only suffers from losses in the gearbox and diff

if the pull was done in a 1.1 gear and the diff is a 4.1:1 the torque at the hubs should be around 4.1 times that at the flywheel.

1103/317 = 3.5  suggests to be that it was done in a higher gear or there is something odd about the calculated figure at the flywheel.
Title: Dyno sheets and discussion for UK Rotaries!
Post by: TwistedHumour on March 10, 2007, 07:41:07 PM
Just checked the sheet and is says that the ratio used was 4.1
Title: Dyno sheets and discussion for UK Rotaries!
Post by: MikeLMR on March 10, 2007, 07:58:01 PM
duh ... my fault. If you loose power through the box but you don\'t loose the rpm\'s (it only changes it due to the ratios there can\'t be an RPM loss anywhere) so you must also loose torque through the gear sets  3.5 is probably 4.1 multiplied by the same loss apparent with the power between hub and fly.

Hi guys can I be added to the table.... The specs on the car are below:

13b Street Ported HKS T04e - built by the master himself JayDee
331rwhp @ 0.9bar

(http://i39.photobucket.com/albums/e181/kash_5/Kash%20RX7/Kash%20RX7%20Spec%20Folder/dyno-graph.jpg)

Unfortunately this was the only high boost run during mapping as either the wheel was spinning or clutch was slipping, also the plugs were very tired and gave up on this run.... not the best result but hoping to do a power run sometime this summer with some decent plugs and HKS twin spark

not at the moment it broke the staionery gear,the 540 was already achieved so it achieved the 540bhp run then it broke afterwards on another run.. its like saying if your car is broken then the last power run does not count ? lol dont worry john i wont be above you on the table as your is slightly higher although with more boost

Not bitter in the slightest either, still enjoying my rotary experience even after all these years :3gears-rh I clearly give people the wrong impression, I dont intend any malice with my comments if you made more power than me I would be the first to congratulate you, I hope once Pip has done the rebuild you come out and crack the 500atw AND it will be a British built engine, best of luck.

Most James\' car has made on RE:Worx\' dyno was late 400s, lol. And it\'s run 10s, doesnt sound too unreasonable? couple of similar hp cars have also made similiar hp on other peoples dynos recently.

Edit: hp numbers are just that - numbers, anyone with a half a brain knows they will often seesaw from dyno to dyno. The rolling road is an incredibly useful tuning tool which is why people pay lots of money for them; the figures at the end are a by-product which when compared to another cars are of very little value. Cant help those with e-peens to feed tho ;-)

Not slating your dyno dynamics so no need to get protective over it.
I just don\'t believe you made a genuine 571rwhp on stripey that\'s all, end of the day it\'s no skin off of my nose if it did, and no skin off of yours if it didn\'t.

Sometimes comes down to driver ability too, James is a very good drag strip racer his launches as spot on !!!!

ReWorx also used a very good driver as well all know, and same goes for Ross who himself is a good driver.

Not slating your dyno dynamics so no need to get protective over it.
I just don\'t believe you made a genuine 571rwhp on stripey that\'s all, end of the day it\'s no skin off of my nose if it did, and no skin off of yours if it didn\'t.
Aye, I know the dyno you are on about (its now closed down i think?). And you\'re right Bri, theres no nose skin to be lost here. I was just clearing up the fact it wasnt 700 or any where near at RE:Worx, and that (not for the first time) people take dyno numbers far too seriously... :driving

Catch up soon Bri :D

What makes you question that sort of figure brian?with an et of 9.8 and terminal of 143,with all factors taken into account,approx weight with driver etc,this figure seems about right,if not a little low.:confused:

Results of the dyno run from Saturday - car was running chipped ECU - no eManage yet, and with boost controller set to 12psi limit.
 
Mods are Racing Beat Exhaust, catless downpipe, Blitz Access ECU, HKS filter, custom induction inlet, Street ported engine on 3mm seals, and Hybrid T04B/HT18s Turbo with Profec B Spec II boost controller.

Shaun

First graph is flywheel horsepower and torque, the 2nd is rear wheel horsepower against boost.  I had the limitter set at 12psi with a 20% drop on boost, so that\'s why the boost drops off a little, although I need to add more fuel at the top end before pushing that any higher.  Boost controller needs adjusting for gain and start gain, as it comes on a bit late so it\'s pushed the curves over to the higher RPM\'s.
 
Good thing is my original torque curve is under this one all the way.  Power has shifted slightly higher in the rev range, but car made peek power at the same rpm as last time - just 100 BHP less :)
 
Just waiting for a bigger intercooler and WI setup, then the eManage and bigger secondaries (800cc) can go on for a bit more ;)

Post by: BlitzBoy on September 27, 2008, 05:41:15 PM
Mixed fortunes today, Geff and Maxy baby of Reworx crew cleaned up the map @ 10psi gained an extra 11rwhp :D

Went for 11.5psi (0.8 BAR) climbing to 415rwhp at 6500rpm (just before peak torque) they had to let off the throttle as afr was 12:1 at 100% injector duty, this due to the size of the Bridge and overlap eating fuel near peak torque. Pretty sure if went to 8000rpm we would have registered 430rwhp at 0.8 BAR.

So need bigger or additional injectors to take us safely past peak torque. This will have wait until after Japshow finale.

Will be running 11psi next weekend, target would be a mid 11 second run, I be happy with that.

Thank you Reworx, destroyed an Aston Martin Vanquish on the way home :spank

well its all to do with flow and effciency, this setup flows so much air but the overlap wastes fuel when its hitting peak torque, if we got past peak torque injector demand would have been much less.
The fuel system as in pumps lines ets are fine its just we need more injector now, Geff saw this happen with Stripy and another car they have in at the moment runs 4x1500cc

Yep,J will be at japshow finale with his car,(japshow 2012 that is).:Giggle

My car now weighs a little less than 1100kgs,that is with 2 front seats,rear seats,carpets,headlining,full cage etc.But unfortunately with the current economic climate i havent had the funds to finish the engine work.Over the past month i have had to cut back alot and re-evaluate things in my business.Hopefully things will sort itself out in the next couple of months and i will be able to come out with something a bit special for next year.

Give you chance to catch up mark,lol:Giggle

I will be at Japshow for both days and am really looking forward to it,especially the pro cars(John bradshaw went into the 7"s today at santapod,his best was 7.78),and of course to see if jeff or chris can beat ross"s record.Chris is running at shakespeare tomorrow,james ran today but broke another gearbox,dooooh.I will be in my subaru so i could give you a race,but that would only be for a drink:guinness.:wiggle

Picked up the car today fook me its fast only took it to 1 BAR

Era\'s baby juice nearly come out when I took him out for a ride at 1bar, the old defi Tach with change up light with the precise action of the Stillway shifter was working beautifully :D

At 1 BAR its the fastest I have ever been in an FD more so when I was dragging at 1.3 BAR on the old setup, there feels no end of power up the rev range I will be smiling for weeks now.

So thanks to Era,Geff,Chris,Max at Reworx, and John Goodwin (who needs to go gym and work on those muscles) who have made it possible

Things depend on how much your injecting, but obviously you know water doesn\'t burn, then methanol burns slower than pump fuel, so to see any increase in power will be dependant on what your timing & afr is at already. Increase in power is also dependant on the % your injecting.
Don\'t expect to see much if any gain without either leaning your afrs out some and or advancing your timing.

Will do, left my dyno sheets at Eras, I will get him to take pics of them so I can post them up, its amazing that the T51 regardless of street port or half bridge produces the same peak power at the 1.2 BAR the only difference I can see in terms of peak power mine holds on longer, but will post up to compare properly

Go to the back of the room and stand in the corner lol I should be able to put pics up by the end of the day Era has got me message.
The good thing all three of us have used the same dyno this should give us proper comparisons of different turbo and engine configs.

I am Suspecting the RE manifolds on my REW engine are not adding to much at these boost levels and the FD manifolds are more effective, the RE manifolds dont seem to work to well at low boost as its an older design even though its bigger. RE manifolds are of a collector design where as the FD is a Dynamic pressure design.

My upper and lower intakee manifold is ported so it\'s not quite the same as stock. My throttle body is stock. I saw huge gains from 1.2 to 1.35 which is when I started to have problems with clutch slip.

Do we know what the peak efficency range for the T51R is boost wise? 1.7 Bar I have heard

I ran mine at 1.9 bar a few times and power cannot be compared to 1.7 at all, the egt was the same too, so peak eff definitely not 1.7 otherwise my egt\'s should of shown significant increase at 1.9 bar compared to 1.7 bar.

I believe it\'s a similar spec to a gt45

(http://www.turbobygarrett.com/turbobygarrett/images/catalog/Turbochargers/gt40_images/GT4508R_Comp_large.gif)

Most efficient at 1.8bar but will make power up 2.5bar.

Here we go Brian dyno attached ignore the thick black line as that is my old setup, look at the thin one, comparing my power line to your its almost equal at the beginning
eg 4100rpm you are producing 108rwhp and I am Producing 112rwhp,
at 5500rpm you are producing 300rwhp and I am producing 325rwhp, so the Hbridge edging it here.
But by 6200rpm (cant be exact as different scaling is used) its equal again at 385rwhp
And still equal at 7400rpm when we both hit 470rwhp, at 8200rpm you lose 10rwhp whilst I am still the same,but to be honest there is hardly and difference, the pull is stopped after this.

I think the difference in mid range is clearly seen where your secondaries are doing there stuff but I thought there would of been the same difference over a broader rev range.
I can also see where after 8000 rpm the bridge is more efficient where there is less time for the engine to swallow due to engine speed.
Torque curve is more or less the same too.
This time round I should lose a little power as I am putting a more restrictive but nicer sounding back box on my car.

yep looks like the only benefit is the midrange and keeping the power longer at upper rpm, does not look to increase overall peak HP not at these low boost levels anyways, will get it redynoed at the end of next year at higher boost if the engine survives the drag season, hopefully Brian will get his car together so he can redyno at higher boost as well for a like for like comparison on thesameturbo

any news on yours?
Title: Dyno sheets and discussion for UK Rotaries!
Post by: sadgoth on November 26, 2008, 04:03:31 PM
well, the map had some interesting spots on it! between 14-16PSI we had a 50% increase in fuel - which should comprehesively take out the leading plugs, then just to fisnish her off at 18PSI a further timing advance of 7 degrees (with only the trailing plugs struggling to work at this point!).

Now the big question is why? That wasn\'t put in by me, Geff or John and whatsmore I should never have seen those anyway as the mapping to 10PSI was safe and we were running off the 8PSI wastegate spring, but the dodgy upper boost map is what killed it!
Title: Dyno sheets and discussion for UK Rotaries!
Post by: BlitzBoy on November 26, 2008, 04:10:32 PM
see you should just map all the cells at all boost levels only way to be sure lol
Lucky for me when Geff mapped my Motec he put good values in all my cells originally back in July when I was running off wastegate spring , i put my boost controller and I forgot to zero all the values I hit 1.4 bar on the old settings :eek on the way to Rotorpop lucky the map was safe in all areas

Post by: sadgoth on November 26, 2008, 04:19:32 PM

Title: Dyno sheets and discussion for UK Rotaries!
Post by: sadgoth on November 26, 2008, 04:40:28 PM
yes, he had a look at the map, leaned out the idle a bit, looked at 12PSI, 14PSI, 20PSI, 18PSI and was mid way through either 14 or 18 before looking at 16 when his laptop died! He did find a few odd things in the map but nothing really scary, but if he never got to 16 then that would explain the over fueling and the bit advance step. Still I guess I should have mothballed the car until I\'d saved my pennies to map it fully, but I thought I\'d be ok running off the wastegate. Very difficult when it was off the road so long!

Gary G done a good time as well 9.5 @ 143mph, a PB for him I think
James did a big terminal as well over 140
So massive power being developed by Rob,James and Gary

Title: Dyno sheets and discussion for UK Rotaries!
Post by: BlitzBoy on October 03, 2010, 09:08:11 PM
hahahah glad you brought that up Lee
Well me and Stu lined up against each other on Saturday, they held us sooo long when we staged (something going on top track), then when it went green I feel asleep and Stu took off, two seconds later I decide to go, Stu had trouble getting second correctly, I hauled him at the 1000ft marker level pegging I surged past him and took the win by 0.1222 of a second.
I clocked 11.2 @ 1 bar he did 13.1 due to his mishift.

I went on did a final run of the day and clocked a 10.95 @ 126 @ 1.2 bar my first 10 since I put the cage in this year

Have only just found this thread. Have just been looking at the top twenty table blitz, isn\'t chris impy running a bit more boost now? 2 bar?

Have you noticed any difference in your car with the cage blitz? Does it feel more solid?
Title: Dyno sheets and discussion for UK Rotaries!
Post by: BlitzBoy on October 08, 2010, 11:56:38 PM
yip the table is out of date, might get around to updating it one day lol

Yes a lot more traction and less flex, hence why I been breaking stuff this year.
But finally dialed in my launch technique with the cage  so I should be hitting regular tens again
Title: Dyno sheets and discussion for UK Rotaries!
Post by: Grant Monkhouse on October 09, 2010, 08:30:05 PM
what has been breaking? gearboxs or diffs? due to more power being delivered to the tarmac? what are your plans for the car in the long run? tubbed back end or are you keeping it streetable?
 
running tens is brilliant, best i managed at rotorstock was a 13.06 on my twins but that was the first ever drag racing i have done, reckon i could have got into the 12s if i stayed longer but my gear box started making whinning noises and had to get home so i stopped. I have just ordered a gt4088 so will hopeully crack 12 easily.
Title: Dyno sheets and discussion for UK Rotaries!
Post by: BlitzBoy on October 10, 2010, 03:03:27 AM
Driveshafts, and at Rotorstock input shaft on the gearbox, the diff wont break as I have a Kazz 1.5 way lsd

no tubbing keeping the IRS to be streetable, more tuning over the winter for higher boost hopefully crack 500rwhp
Title: Dyno sheets and discussion for UK Rotaries!
Post by: Grant Monkhouse on October 11, 2010, 02:18:45 PM
How much more psi are you going for? 500 rwhp is nuts. What is the car weighing at now? Even with the cage I bet it\'s lighter than my car.

It amazes me the difference in uk rotary hp figuresand times compared to the Aussies. 500rwhp seems to be minimum for a slow drag car over there, even rx3\'s embarrass our best our fastest rotor.

Hopefully if people keep pushing development we will have some really nuts rotaries.

Are you running wi or are you on race gas? Or neither?
Title: Dyno sheets and discussion for UK Rotaries!
Post by: BlitzBoy on October 11, 2010, 02:34:24 PM
Well UK dyno 500rwhp will be enough for high a 9 second run if I nail the 60fts again.

Well last time it got weighed with me in it and some fuel I think it was circa 1250 kilos, I weigh 90 kilos so about 1160, have dropped some weight since that weigh in, lost the carpets and the heater unit, have a heated screen now, so hopefully around the 1130-1140 kilo range now.

I should hit 500rwhp at 22 psi, target is 28 psi.

I use 99 vpower to a third of race gas to keep it safe, but tbh honest at 1.2 bar it does not need it,I run straight pump at 1.1 bar for the road, will use 50:50 pump and race gas at 22psi, I will be installing the WI back on for the higher boost
Title: Dyno sheets and discussion for UK Rotaries!
Post by: Will66 on October 11, 2010, 06:29:09 PM
28psi should be close to 700bhp if my brief calculations are correct.  That\'s a lot of power whichever way you look at it.  I do like a bit of HKS Drag series so it\'ll be good to see another quick rotary!
Title: Dyno sheets and discussion for UK Rotaries!
Post by: Indian on April 18, 2011, 09:54:36 PM
im sorry to bring this thread from the dead... But are you saying he should make 200 more hp with 6 more psi???  If thats the case, then i need to go to him for rotary advise..
Title: Dyno sheets and discussion for UK Rotaries!

It\'s called not having 0.8 bar boost till ~6500rpm! Large Turbine wheel and housing = less pumping losses against the engine and you can make big power at high revs with lowish boost.............. only problem is mid range is non existent and IF you try this on the street with quick transient response it would not make its full boost till 8000rpm or so especially in 1st, 2nd or maybe even 3rd gear as no where near as much load is applied as is on an artificial dyno run.

On the road this set up would be totally crap :)

On a drag strip with all the correct ancillaries it would be o.k. :Thumbsup!

Lets not sugar coat it, that motor would get beaten by a Datsun 120Y at any revs below 6000rpm lol. It would NEVER work in any road car, or with any road exhaust system, by work I mean fast. :Hammer

It\'s all about being fit for purpose.
 
The purpose of this car is to cover 1/4 mile as quickly as it can within the rules of its series.  I\'ve seen it run and it\'s damn impressive, it may well not be able to pull the skin off a rice pudding at low revs but it covers the 1/4 mile in 9.98 seconds (it did it on TV too) so I\'d say that his choice of turbo is pretty good for its purpose.

yes the engine/turbo config is built for purpose of drag racing, obviously on normal roads you would have a totally different configuration. He has a HKS dog box to help keep him high in the revs.

He is looking top hit mid to low 9s this year

BTH Driving the car on the street it is no where near as laggy as it looks on the Dyno, it has "full" 0.8 bar by 4600 rpm, i will try and take a in car video driving and maybe with a map trace to show the boost curve, even on a partial throttle the car pulls surprisingly well. btw the turbo is a 72mm inducer not as big as people think.

I can see the point of Rice, and also of the Jaydee. But, in my underdevelopment experience, which is getting development offcourse, I think, the statement of "fit for purpose" will be seen once the Car is shown in action...

The graph shows a lot and If I am not mistaken, Rice was suggesting his point of view on the figures shown in the Dyno Sheet.

Jaydee, has yet to provide the video to prove his point of "laggy" business...

That would be good.

Don\'t take my typed words the wrong way (for everyone).

What frame turbo is it? what specs? (Turbine & Housing).

I\'d like to see what boost it will make accelerating through 2nd gear and say a 3rd gear roll on from 4000rpm, From my experience of dynos at that power level and used in shoot out mode, it will be over 1000rpm laggier in lower gears as I type above.

If its driven up a hill in 4th gear or loaded up excessively then it may make boost sooner than on the dyno sheet :Thumbsup! Transient response will however be bad, but that is not the point of the car or the set up so all this .... is irrelevant lol.

Good ............no................ GREAT POWER :god

Had a great time at The Worx garage today.

After prolonged battle with my mind, I finally convinced myself to put my 20b on the Dyno!! I was happy with a result.

I made 520BHP at only 0.7 Bar a Boost and at 6500 RPM. The guy who was working on the Dyno said, my car can produce alot more, If I sort out my fueling as I was running almost lean! I just can\'t thank Allah enough and above all a very big thanks to WGT!

Video to follow!

For now enjoy the picture!!:cheers

Good stuff. Now turn up the boost you wimp and get near to the 1,000 you want. I was at pips the other week and talked about your car. From what I managed to squeeze out of him ( he wouldn\'t tell me much ) you are looking at a huge amount of money for 26B twin turbo. He wouldn\'t say exact but I would guess that £50,000 isn\'t far off?

Your gear box alone will be in the region of 6-10,000 alone.

I would say save your money and finish the 20B

Exactly Ed mate! I need that wastegate off you! The wheel power? I dont really know! We called off the session in the middle as the engine was going lean (AFR 14.5)! Once I get that wastegate off you and Pip remaps it for me, I would know for definite the exact power of the Car. By the looks of it, (and I am happy to be corrected), I think I will have 700HP reliable at just 1 Bar of a Boost.

I have to sort three things out now
 
1. Install the Mocal Oils Coolers 25 Row x 2 (Already bought them off Jit)
2. Install the 60mm Wastegate (Prov Bought :D)
3. Sort the fueling out! (Bought the second 044, now need a intank cradle which can take twin pumps as I hate the sound of "two external" 044s!!!

Well I am lucky for the first time in my Life to have a running car in Oct times!! because eversince, I owned an fd, my car had been a garage queen lollll I know 14 is not a good figure! But there were two reasons for putting the car on the dyno, firstly, I wanted to know, the limits of pushing my car-now I know, I should not go above 6 RPM and secondly I also wanted to know the leaning point of the engine, which is again over 6RPM.
 
Pip advised me that I should take it easy with the car as it needs further tweeking! Hence, at Rotor Stock 8, I was running low 12s! I never gave it a full throttle on the drag strip! Now I know my limits so I can work on them!
 
I know one Fd which was running 16 AFR(at low RPM) I am sure you know him too!!!!!!! and I was like, why it not blowing up :(? The guy said "dont worry, it will adjust itself :Hammer:Hammer:Hammer"
 
Eversince I saw that!!! I was confused as anything! How can that be adjusted "automatically"?? lollll
 
Thanks God/Allah the motor is fine and I checked the catch tank, there isn\'t much oil thrown out which is further a sign of good side seals

The results kinda matches with Pip\'s advise, he told me that the motor leans out at high RPMs and he needs to adjust few things. Actually the culprit is the wastegate, which is playing up!
 
Once all the things are addressed, I am sure I will have a nice daily driver 700Hp!! Thou I may be optimistic!!:3gears-rh
