Well, I got my car back today from being mapped and dynoed, and thought I\'d see if anyone wanted to play the always-fun guess the results game.
Bearing in mind it\'s on stock ports, stock twins and stock fuel system, but with 850 injectors in the primary, and thats pretty much it. Apexi PFC, Profec II boost controller holding .8 bar, Trust SMIC, straight-through ARC titanium exhaust and Apexi intakes. Stir in a little bit of Super 7 mapping trickery and serve whilst piping hot :Giggle
So, place your bets...whoever\'s nearest may or more likely may not win a totally useless and redundant prize..I think I\'ve got a penny chew lying around somewhere :D
300 at the fly:Thumbs-up
oooh, bit stingy there Lee :(
hmmm, i\'m gonna say 307.8bhp at the wheels
Gotta start somewhere :Giggle 330 atf
Any better
Quote from: Bobbit;611848hmmm, i\'m gonna say 307.8bhp at the wheels
Blimey! I wish, dude. Oooh, Lee\'s close now. :)
Forgot to say its also got a silly large HKS downpipe on it too. Soz, my bad :o
335 atf:driving
328 at fly??
tho i have no idea..
Quote from: lee mills;611857335 atf:driving
Hee hee! You\'re gonna get the penny chew just by going up in .5 hp intervals till you get the right number at this rate :rollin
340 atf i want that sweet:chat
150@flywheel :Giggle

PMSL:evillaugh...
come on time to put us out of our misery
Sounds about the same as mine, but it depends wether it\'s been rebuilt or not. If not i would say 330fly
Sorry about the wait...forgot I had me mum coming round for tea tonight, of all things :HammerDoh!
I think the penny chew has to go to Lee for getting closest, although he did pepper the target with random gunfire rather lol :Giggle. Dunno how well the scans\'ll come out with the new MRC stingy pic size thing...

To be fair, I\'m not so exited about the 336 at the fly as I am about the 268 lb/ft of torque and the shape of the curves. I\'d sacrifice a bit of top-end that I never use on the road for grunt off the midrange any day, and the car just flies out of mid revs now. We\'re chuffed with that, we are :D

Cheeky bugger :p I\'ll definitely be cheering for Liam at RS6 now :Giggle
hehehe but you should be on the FD side of the fence :Ladys-man
Hmmm. Be easier to choose if your cars weren\'t both red. We all know red ones are faster, but what happens when they\'re both red :confused: It\'s a hopeless situation :Giggle
Nice results bud, good choice on mid range power, should be a great road weapon now. Find some 350z\'s and show em who\'s boss!
I gotta say, I can\'t belive how good a result it is given the stock ports, fueling and twin tubbies. Jason worked some mapping magic there, and his super-secret trick of machining the primary rail so as to let the bigger injectors seat properly and maintain spray pattern has clearly done wonders. :chuffed :yes
good results mate and about time i won something lol:wiggle
Won\'t be long before we\'re looking enviously at your version of this thread, Lee. Feel the lurrrrve :Giggle Now all I\'ve gotta do is resist the urge to scoff your prize between now and RS :rollin
picked my car up on wednesday made 528 fwhp at 1.4 bar but noy a very smooth power curve porting is to mild. But hey good news is im keeping it now and its going to Tim,s @ RXMotors on monday:god for some nice brap brap porting and more power:wiggle:wiggle:yes:Thumbsup!
Happy days then. Thanks for plssing on my bonfire quite so quickly :(! Only kidding, 528 at the fly is plenty mucho good :yes
it is but i think it was pushing the porting to the max so would rather make the power without so much stress on the engine. And also im chasing a 10 second run
very nice. id be very happy with those results :D
how did you find austec?
I didn\'t get there. J had already gone up with the car when I turned up yesterday, so I missed the actual dyno bit. Shame, but the way my luck goes, if I\'d been there to watch it would have shlt itself on the rollers :rollin
great torque figures Nik,
But on the subject and just talking about on stock ports,
How come the torque figures vary so much between engines with similar mods, Pip got me 270odd lb\'s/ft,( Ill have to check) but i also see a lot with 220-240lb/ft always around the same 300-350fwhp.
Is it just in the tune or does it give any indication to the health of the motor??
lee.. you jus got ur 7 back.. and not its off again for a few weeks for more porting..
hope u manage to get ur 10sec car =)
nice figure nik.. i saw the graph n was squinting to read it.. then gave up.. scrolled down some more n saw an enlarged pic lol
Its got to be done mate no point raing if you aint competitive:Giggle you might see it sunday as im driving up to frome late afternoon
be nice ot hav a pokey around.. i\'ll be there 4pm onwards.
come stop round at my shop.
golden sand, 40 vallis way :)
might do if i can find it. gotta meet my inlaws then drop the car up to tims give us a post code for the sat nav and ill pop in and say hi
i pm you.....
will this be going to rotorstock6, and i would be happy so you could always put it in my 8, well done

I thought about this too. Mines at 320 bhp fly, 278 Ibft
mine did 324.1 at the fly and 268.0 at the wheels at reworx, similar rwhp but less fwhp for some reason - similar mods but no airpump
Quote from: RobbieRX-7;612086I thought about this too. Mines at 320 bhp fly, 278 Ibft
Pretty much identical figures to mine, But most dyno sheets ive seen show something more like, 320fwhp 236 lb/ft.
What is the standard 255hp rx7\'s torque figure ?
good figure for .8bar tho, how does it compare to before??
lee, your car is going to make some nice power at 1.4bar with a bridge :D you going full or half??
probably full but will speak to Tim first
Nice to see your Car going well Nik & some good Figures there :yes
Its alright for some,I been Banned from Driving by my Doctor:eek:,as had a Accident with my Left Knee!! My RX8 been parked on my Drive,since last Tuesday Afternnoon:eek

Pah! My fd has sat on my drive for 2 years :(
Hi Nik,
Great results :Thumbsup! Be interested to see how it compares to mine in terms of driveability. Are you coming up to rotorpop - will see you there for a beer if so :guinness
Chris.
nice results on a stock engine, interesting how they calculated 20% losses (drag) most people say 18%, good for pub torque i spose :)
Lee, did they find out what the issue with your car was?

Yep was the race fuel:mad:
Haha pub torque, very good. I wondered about the 18% thing, too. Can\'t answer that one, I\'m afraid. :3Confused
Cheers, Mr Beast! Sorry your \'8s out of action atm, dude, but at least it\'s better to be banned by your doctor than by the Courts :)
Karl, it\'s bloody excellent mate. Especially since I had it with the boost held back to .6 bar before because of the injectors maxing out, so it was well slow. She\'s a goer now :D. I still think it\'d be faster if you let me have my shopping list back though lol, that\'d be worth another good 10 bhp
Chris, yeah, I\'ll be at RS mate, I\'ve got to prove to Adam that red ones are faster than black (although I can\'t shout too much about that or Lee will prove yellow ones are fasterer still). See you at the bar, dude :cheers
Thanks Nik:)
If only I had a Auto RX8:2Rolleyes,then I could still be out driving my car & not worry about the Clutch Pedal:Giggle
Tip for you,Next time you go for a Tune Buy a Rise rate Fuel reg and a Bosch 044 Pump then have the Fuel pressure turned up, Then hey presto you will have a car capable of 310-320 at the hubs.
528 is enough power for late 10s if everything else like launch and traction is good.
Good result Nick, thats enough power for mid 12s
D\'you reckon? Better brush up on my technique then, and I may stand a chance of making Ada kiss my rosy red butt :D (*ahem* metaphorically :o).
Only annoyance is the pops and bangs you get at 2,200 rpm on a trailing throttle. I wouldn\'t mind, it never goes that low on the road, but in 30mph-ish town traffic it\'s impossible to avoid. Soon as I decelerate at 2500 revs it just goes pop-pop-pop-POP-BANG!, guaranteed. Fun for a bit, but it\'s a bit embarassing at times.
Wonder if it may be a dry join in the exhaust? My old Akrapovic used to do it on my FireBlade cos it was all held together with springs, and it used to draw air in through the joins slightly on the overrun. Any ideas, anyone?
Its not exactly a smooth 528 though mark was pushing the porting to the limits and then some:Laugh

Mines just started this after spending the entire weekend under the bonnet tracing the rats nest and sorting out loose pipes etc. I\'d be interested in anyone response becasue as Nik\'s said it is fun but driving through our quite little village i do feel a bit of a pillock.
