standard engine except power fc and commander,hard pipes and twin induction kit - before pipes/induction mapped at 225 RWHP,dont have a boost controller.
dont want to go mad but like to see around 280 RWHP whats the best route(presume fuel pump & injectors a starter) ?
pete
It depends on what you really want. You could decat and remove airpump to get more ponies but you will probably want to increase the size of your injectors and put a better fuel pump in as well. You may want to swap the stock intercooler for a bigger stock mount too if raising boost levels.
It will make the car much louder too so if you do alot of motorway miles you may want a silenced mid pipe.
280RWHP shouldn\'t be too hard to get, you\'ll have raise your boost level too to get to that figure.

Cheers Shaun,not worried about being a bit louder my exhaust is a dunke megaphone it makes a stealth bomber sound loud :rollin .
due mot july have to see how emissions come out not got decat pipe on at moment,bit of faffing about when i had an evo putting cat on and off for mot but should give another 5 ponies or so if decat fitted.what size injectors is it going to need around 850 ?
had a walbro pump on my evo was loud when just ticking over whats the bosch like do you know ?
Pete
The stock injectors are 550 and 850. Usually people upgrade to 1200 on the secondarys to get a bit more flow. Pip at WGT upgraded my pump and injectors so not really sure what im running pump wise. It isn\'t any noisier that the stock one.
You may find that it can be tuned without the injectors needing to go any bigger. I think the cutoff for the stock injectors is around 0.85bar of boost. Im running 1 bar and see about 75-80% duty max on the 550/1200 on a rich map.
I\'d say fit a bigger stock mount first and get it remapped and assess what you need to do to your fueling, any of the tuners on here will tell you want is best for the car !
Jon (hotstepper) is running about 0.9bar boost on stock intercooler and stock injectors without too much headaches !
Shaun
thanks again shaun - takes a bit of getting to grips with RX7 after evo especialy when talking of boost levels like this as my evo after ecutek done on ecu was at 1.5 bar - learning as i go along,should get a boost controller (either AVCR or Blitz ) as well as change intercooler.then looks like a trip to manchester for remap
Pete
Mine has got 280 at the wheels at the moment and all thats different from yours is its decated and been mapped well. Standard engine, intercooler and injectors, running 0.8bar :)

strange wonder why so diferent decat only adds 5 ponies or so,mine was mapped by reworx before i got it wonder if been an ultra cautious mapping ? Had a quote from "sam the dentist" for mapping was £400 which i thought was high for a remap job plus rolling time at scoobyclinic which was £75 last time i had a car done - did include 3 runs whilst ecu was flashed & mapped

Unless you have a cold air feed for that induction kit I\'d go back to standard as induction kits sucking in hot air = less power.
I\'ve got standard engine, apexi, HKS downpipe with Re-amemiya mid pipe and catback, non seq turbos and made 285 at the wheels.

Bulla was mapped before induction kit added,no cold feed yet

Pete if you don\'t want to go new intercooler you\'ve also got the water injection route.
Kevin
I\'d go for the greddy profec b spec ii for boost controller, infinately adjustable !
I\'d go to wgt for your mapping session, closest place i can think of ! Maybe the downpipe and cat bringing your figures down. If you off to manchester its only another 30 mins down road.

how are you doing?
Think intercooler is my prefered route dont know which is best to go for in my case spent a lot lately with new bonnet (spray costs to come yet GULP ),induction kit,hard pipes and suspension

Shaun - intend to go to wgt knew were manchester (ish) didnt make it clear above when on about "sam the dentist" mapping (great bloke knows evos and scoobies but not sure on RX 7\'s) want to use someone who knows the limits on mapping safely an RX7.
never thought about greddy boost controller thanks will take a look at specs had a blitz dual sbc in evo was simple 4 settings for boost
Pete
I\'m planning similar things to those above, but with teh adition of water injection, have you considered that?
Quote from: cannibalI\'m planning similar things to those above, but with teh adition of water injection, have you considered that?
to be honest dont know anything about water injection nearest was on my evo had water spray to cool it - manual version,need to do a search to find all info on it
Pete
The waters injected into the airflow before fuels added to the mixture :p
Lots of threads on the subject if you do a quick search !
Pip is very good and won\'t go too silly with the mapping.
Shaun
ordered greddy profec b spec ii boost controller today, next will be intercooler - whats a reasonably priced decent one thats not going to involve lots of hassle fitting ?
Pete
The SMIC are the easier to fit but they still suffer from heat soak off the engine. Id say that most of the front mounts aren\'t too hard to fit just more time consuming, took me a long time ! Id almost say go for the dragon v-mount because they all involve removing all the plastic and rad and repositioning it all.
Give me a shout once you get the profec fitted i\'ll pm you some settings to get you started on the right track !

Cheers shaun will have to look around saturday on IC\'s and call to see mechanic get an idea of fitting costs as seem to have loads on the go for the car.waiting for paint sprayer to pick up new bonnet i want spraying/fitting,needs geometry setting up now teins on,sort rattling boot catch out drives me crackers then when IC and boost controller in remap
Pete
Make sure you get a decent FMIC with spaced out fins as your rad temps will go up if you are restricting the air to it. Not that i have one but thats what i hear .
a V-mount is the best as clean cold air goes to both... but much more expensive though.
Quote from: Sy.a V-mount is the best as clean cold air goes to both... but much more expensive though.

Both are a very big job to do, the labour cost may be cheaper on a v-mount !

No need just go straight to Radtech they will supply the rads cheaper! It was never Ross\' design so there is no need to feel guilty ;)
The rad is a great design though and would be a good investment if you ever deside to come back to this thread again saying now I want 500bhp :D

Whats always bothered me about that vmount is the pipes
(http://www.dragonperformance.co.uk/productimages/f-87c4a044-c9ce-4507-a9e7-469f159e3f46.jpg)
Because those bends are not smooth curves, thats terrible for flow. I would always go for something with totally smooth curves - you\'ll loose less pressure that way...
Ta, Paul.
You still get some pretty heavy curves with the FMIC plus the pipes are longer too so the charge has to travel much greater distances.
Shaun
I\'d love to see if the v-mount suffers more from heat soak off the radiator and engine though !
Shaun
Quote from: shaunwilYou still get some pretty heavy curves with the FMIC plus the pipes are longer too so the charge has to travel much greater distances.
Shaun
I\'m not saying Vmounts are worse than front mounts, i\'m saying that vmount is a bad design. If the pipes were smooth curves not chunky angular parts welded together, it would be a better design.
Ta, Paul.
having had a quick look at intercoolers V mount is an arm and a leg and quite an expensive job to fit i cant justify it to myself,can get an XS power SMIC for £190 and is cheaper to fit, Trust FMIC is around £430 and a fair job fitting costs wise.
only seen a couple of RX\'s on here using XS power so dont know how good they are.
with the cost of spraying new bonnet ,fitting boost controller and a remap to come think i will go down the SMIC route sure its still better than stock IC and i dont have temperature problem never goes above 94 degrees in slow traffic normal running is 82 to 83 degrees going by commander
Thanks for views given

i have now fitted my FMIC so i have a nice alloy uprated SMIC for grabs?? fitting is a 1/2 hour job.

i do have some pipes buts they go with the Gredy elbow.
im looking for £175 for the IC and £80 for the pipes.

Hi Shaun,at long last SMIC and boost controller fitted - Profec settings not done yet if you can send me them please,also booked in with wgt 21st for remap looking forward to that :mmmm
no problem, what level of boost are you hoping to run. I\'ve got mine set about 0.95bar on high and about 0.6bar on low. I\'ve got uprated fueling so 1 bar may be too high for your current setup.
I\'ll go and write down what the settings are !
Shaun

Cheers shaun playing safe go for .90 max .6 low then let Pip sort week monday
good advise guys as im also thinking of more bhp but just with add on`s
looks lkike the bussiness bank accounts going to get hit hard soon.lol
Right, I\'d go for about 0.8 till pip sees the car, don\'t go too crazy until you know that it can fuel what you want.
My current settings are :
LOW (about 0.65bar)
Set - 10%
Gain - 13%
Set gain - 0.55
Warning - 0.80
Lower - 10%
Peak - ON
HI (About 0.98bar)
Set - 39%
Gain - 22%
set gain - 0.76
Hi - 1.15
Lower - 15%
Peak - ON
Start with the low setting on both and then find a nice straight road with a roundabout both ends, get the car in 3rd and do a Power run from about 3k to 7.5k watching the boost (or get a passenger along) rise. It should be stable and shouldn\'t spike at the beginning. If it does spike the set gain may be set too high.
Do it in very small jumps and then find what you want.
Don\'t overdo it, keep a very close eye on injector dutys on your pfc too and don\'t go over 85% anywahere in the rev range, more likely to be in the higher rpm points.
PLEASE DON\'T GO TOO FAR AND POP YOUR ENGINE DUE TO TOO MUCH BOOST. THIS IS ONLY A GUIDE AND MAY BE DIFFERENT FOR EACH CAR.
Hope it helps and you will have fun finding the settings :3gears-rh
Shaun
Thanks Shaun
spent today with the wife we took front wheels off for a good cleaning took ages to get some of the brake dust off painting the grey parts of them (BBS wheels) gold,may only get fronts done today 2 or 3 coats she says will do 1 rear monday other tuesday when home from work as in long before me :InLove cracking woman
Agree on the greddy profec b spec II, was recommended also to me.
I\'ve got HKS RS induction (have a headlamp air duct feed for colder air), HKS 76mm downpipe, KnightSport hiflow cat midsection and HKS Hiper cat back box, SARD 280ltr fuel pump and 850cc secondary injectors, all mapped by a Apexi PowerFC.
Haven\'t had it dyno\'d but I\'d expect about 350bhp ?
Not sure if this figure is correct or what to expect figures-wise for at the wheels ?
IC is probably the next thing on my list, apart from better brakes !
Are the HKS or KnightSport V-mount kits not any good ??
Quote from: Devil\'s RefugeeAre the HKS or KnightSport V-mount kits not any good ??
Dont know about those 2 but not happy with fit on the XS SMIC i got sure that pipes & IC were for another model,pipes have been cut/welded to fit,bonnet only just shuts,induction kit is squeezed in,strut brace touches the pipe at left side, right side has washers under fastening bolt on brace to lift off pipes as was pushing it down and had to use HKS pipe i had on before to get it something like square.expect Pip at WGT to say its an abortion or laugh - very disappointed :reallymad suppose i got what i paid for a false economy
Don\'t know how to post pics. I can give you a pic of an engine with the KnightSport V-Mount. Very nice, and the pipe work is infinitely better than the look of the Dragon unit
Ah, here we go
http://i112.photobucket.com/albums/n175/Devils_Refugee/VU1S9850.jpg
Nice, I had to lift my strut brace up with the greddy elbow to get it to fit, just one of those things. Will help to stop the engine rocking under heavy throttle ! Devil ref i\'d expect about 290-300 at the wheels. I\'ve got slightly bigger scondarys (1200\'s) and run happy on 1 bar and get about 320 at the hubs and 380 at the Flywheel !
Shaun
Shaun settings for boost controller were massive help thanks a load
No problem, happy to help ! I know I had alot of spikes due to setting the set gain too high !
Have fun :)
Shaun
Shaun will have fun after Pip trip,having a steady run to silverstone sunday morning then upto WGT at night ready for mapping session monday morning :)
Will be nice to see what it gets on pips dyno, I saw 300bhp at the hubs last time i was on pips dyno.
Enjoy

so long as better than 225 rwhp by a fair bit will be happy - 300 is a good result shaun :burnout
2nd stage started got trust IC from nurspec coming to replace xs power one,booked in with Pip for modifying wastegate,uprated fuel pump,additional injectors and remapping - looking forward to rollers figures last time was 287.5 ATW
trust fmic?? or smic??
So whats the score with wastegate boring out jobby whats the price?
Quote from: rmagictastictrust fmic?? or smic??
smic going on

Give us a buzz when that needs to get done.
picking car up from wgt wednesday wastegate modified, power is now 305 at wheels, 360 flywheel, fuel pump fitted is a Walboro 255lit/min, additional injectors are 2 x 550 cc plus trust greddy smic fitted pip says goes well boost straight line
whats the next stage to up the power,staying with twins
good figures there with twins....WI may help also to up the boost a bit with Ignition Amp and some good plugs...:Thumbsup!

Cheers trouble is we are never satisfied always want more like oliver twist :D
Got NGK 9\'s all round,looked at WMI before deciding on greddy SMIC instead,Pip mapped and is known for being safe - not a bad thing
Greddy SMIC is the best...what boost are you running at present...

Pete,
I made 322 atw on stock twins, with WI and the rest @ 1 bar boost. Blew the tubs shortly after. Now I have gone single and it is infinitely better
The stock tubs don\'t like being runover stock boost levels for too long, as I found out
Not only this but because they are so small (in comparison to a nice fat single) they heat the air up a lot more which can\'t be good for the engine
If you want MORE power, I would with the benefit of experince recommend you think about going single. IMHO the stock twins are not work much more than 320 atw.
And when you go single, trust me you don\'t feel like you need more.. I have been running on the low setting of 0.8 bar and it is more than enough infinitely better than the stock twins

You can get a HKS twin spark for less than that (pm me). Im making 320atw running at 0.95bar. I\'ve topped out the turbos, but they seem to be ok for the minute. Insurance is usually a bigger headache with a big single.

only want short bursts for drag strip, sure i read someone on here runs stock twins and pulls something like 380 rwhp ,must be in a table here - i would be happy (for now LOL ) with 340rwhp.Have a desire to stay twins, dont know why just got it in my mind - engines nice & strong year ago it got 8.4 fronts and 8.3 rears on compression test at reworx
Thanks for input mate,appreciated - maybe in the future will consider singles but dont want to throw a shed load of £££££££££ just now at car
380rwhp was John\'s "Warthog" car and he had extensive work done to get it at to stage! e.g using cosmo engine parts etc
And he still gets overtaken by a golf diesel! ;)
