View Full Version : S52 M roadster v. Stage II Sti
MikeHsu 01-18-2006, 09:49 PM My car:
M roadster 00' S52
ECIS Intake
M50 Intake Manifold
Dynoed at 229whp/210ftlb
My friends sti:
Stage II
Close to 300 WHP/320ftlb
We did a 20 MPH roll to 80 MPH. He started at first gear and I started at second gear. Honk 1, 2 3 GO, He would pull right off the line, once he change into second gear, I would pull ever so slightly. By 80 MPH he was one car length in front of me. I was expecting to get my ass handed, but he told me that he's suffering from slight boost leak. Overall, I was impressed with the performance on my car and was shocked at the outcome. This was done in a closed course and both are great drivers. :buttrock
Stealthauto 01-18-2006, 09:53 PM Honorable death! :)
That sounds like a sweet STI
nismo skyline 01-18-2006, 09:56 PM i wonder what the outcome would of been if you guys would of taken it up into the triple digits
ugaroadster 01-18-2006, 09:59 PM This has me pretty excited lol. My friend has a 301 awhp STi. I wish you'd have gone into higher speeds, I'd be curious to see the outcome.
02ImolaM3 01-18-2006, 10:09 PM wow....im surprised that he didnt beat you much worse.
intence 01-18-2006, 10:27 PM he should of been in 2nd gear.
JBgotM 01-18-2006, 10:39 PM he should of been in 2nd gear.
yes, 1st gear at 20mph in theSTi is kinda pointless.
Remeber the STis hauling around more weight than the roadster as well. I am a big fan of them and have worked on them at least as much as I have worked on my own car. Me and some friends went to Putnam Park road course outside Indy and did a track day. I was interested to see how my car would stack up to his down the straightaway.
His '05 STi: stromung downpipe, stromung midpipe, stromungintermediary, and a stock muffler with a Cobb Stage 2 93 octane map (18 psi). The car makes about the power mentioned in the first post above.
My car: see my sig, lots of bolt-ons, stock gearing, 250rwhp.
Down the straightaway (probably ~1/2 mile) I was right there with him all the way. He put maybe a couple feet between us. He was a little surprised to see me right on him at the end of the straight. My instructor was pretty damn impressed.
He and I both wieghed our cars at the drag strip one night. He was about 3500 pounds (and he is a beanpole), and I was 3180 (I wieghed 255 then) and I had my passenger seat out (to haul my tires to the track).
giterdone 01-19-2006, 01:26 AM Nice death. I figured he would've did better, but him leaving it in 1st was kind of retarded.
v8killer2pt5 01-19-2006, 09:20 AM UMM please don't take this the wrong way but that's not typically how it should have went down. That boost leak must have hurt alot and his choice of gearing could not have been worse. I can't remember off the top but 20 mph in 1st is probably redline or close to it. I give you credit for good driving but he should have put some distance on you. But hey anything can happen , once again good show man!
streetrcrm3 01-19-2006, 09:46 AM Stage 2 STi only have 300whp on pump via dynojet? Please tell me that it puts down more.

Yep that's it unless you use water or meth injection, reason being is the IHI VF 39 "Sti Oem turbo" is maxed at that. Approx about 370 flywheel, or crank whichever way. I am for all intensive purposes Stage 2 minus a complete exhaust, I am running the stock axle back for stealth, no cats and a conservative 17.5 peak psi. But the car spools instantly and torque comes on quick. Maybe it's the weigh or he was offboost? If he did not brake boost or bring the rev's up at that roll in 1st I see how the outcome could have happened.:shifty
JBgotM 01-19-2006, 11:21 AM honestly, it seems about right to me. It both went from a 5mph roll in first then I would expect the STi to pull a little more than that.
The STi had poor gear choice (and you could argue that the roadster did too). The STi has more power, but also is heavier and has to shift more often than the roady for that race.
but yes, To get much more than 300awhp, you should swap out the VF39 for something else.
yohan7 01-19-2006, 11:58 AM I call BS on this kill! J/k I was the one driving the sti. There's few things I want to clarify;
- I was indeed suffering from a slight boost leak during the race. I've checked the hoses, resetted the ECU and the car now hits target boost. It's no excuse though, run what you brung.
- I was never in 1st gear, as it's pretty much useless during roll-on races.
- I didn't brakeboost either, as it's not necessary to do so with the vf39 being small and fast spool up.
Overall, I was suprised that his S52 M kept up pretty well, he fared better than most E46 M3's I've raced. There's one thing I might point out....he has MaD shIFting SkiLlZ that I cannot match. He shifts faster than I can so that might constitute towards his favor.

I am not a big fan of water/alky/meth injection b/c if the system fails at WOT then you have some serious problems. Does stage2 get some sort of off the shelf base map thru some form of engine management? My friend claims his car is a monster after he got his utec stage 2 map in his car but I don't see him making more than 300 whp on 93.
I can only think of one piggyback that should have fuel cut abilites once it detects something wrong with the alky/meth/etc. injection and its still being developed.
MikeHsu 01-19-2006, 12:51 PM we are going to run again and also on the highway. Hopefully I can get some mods in by then

JB, I would say the roady's gear choice was bad, unless the driver knew he was not very good at shifting.
Yohan, cool to see you chime in. Since you say he has M4d $#!ft!nG $k!ll$ I don't see why he was in 2nd, that bogs the hell outta 2nd, 20mph is where I shift to 2nd if I am just cruising around town and not trying to go AT ALL. But either which way, both people had alibies, but at least all in all it was a good, fun race.
JBgotM 01-19-2006, 01:20 PM ....he has MaD shIFting SkiLlZ that I cannot match. He shifts faster than I can so that might constitute towards his favor.
go see www.turninconcepts.com and get the Super Shifter Set and welcome to shifting heaven. Seriously, it makes a huge difference.

If he is running a utec (piggyback), then yes you can get a stage 2 map from TurboXS, but most guys with a Utec will change out some other parts and get a custom dyno tune. My buddy has a Cobb Accessport (reflash) at stage 2 and it is off the shelf and you are indded leaving power on the table. The Ecutek like v8killer2pt5 is a custom reflash system.

Ecutek great tuning tool and even though the initial license fee of $350 sucks its well worth it b/c of its setup and tuning advantages vs. techtom reflashes.
Any ideas what a stage 2 via ecutek will trap in the 1/4? I honestly don't see a stage two with pump gas going faster than 12.5, but I could be wrong.

Stage 2 should run around 105-107 traps. I have heard people dipping down to mid 12's but high 12's and low 13 seems what everybody's getting consistently.

thanks that should be mid to high 12's

Yes the vf39 does spool fast but building boost would help alot. I was thinking the same thing a few E46's I have met up with did not do nearly as well as he did > good driver!"

I agree, will never use any kind of injection, drug or other wise..lol- Off the shelf maps or ok but not comparable or safe as a dyno/road tune. Anything using the VF 39 besides injection will at best yield 300 awhp give or take.
v8killer2pt5 01-19-2006, 02:52 PM Oh sorry to add so quickly but the best a stage 2 could muster is a mid 12, high 12's are the norm at the aforementioned 105-107 trap.
MikeHsu 01-19-2006, 02:55 PM My shifting isnt tht great...
When I drove his sti, it feels like its so hard to shift fast. Although the throw on his gearbox is much shorter than mine, his RPM drops so slow in comparison with my car.
JBgotM 01-19-2006, 03:10 PM When I drove his sti, it feels like its so hard to shift fast.
yes, and alot of STi owners are hitting the 3-5 gate when trying to shift into 3rd quickly. That's one thing the STi needs is a good dhifting kit, it makes a world of difference.

Thanks for the heads up....I shouldn't have a problem come track season :)
1BMW2VWs 01-19-2006, 11:15 PM Sounds reasonable. An STi got me by a car length or two a few months ago.. all I could see he had was an exhaust.
yohan7 01-19-2006, 11:37 PM we are going to run again and also on the highway. Hopefully I can get some mods in by then
By then, you'll have your turbo done right? lol
edit: Anyone know why I can't put smilies? I always get this msg saying that I don't have permission to use URL's.

I like your style. If I had an STI I'd do the same thing. I never really considered brake boosting during a roll on. Maybe I'm a noob:rolleyes ? I think I'm going to try it. The only downside is simply warming your engine and intercooler ever-so-slightly before its time to flog it. The lag really doesnt hurt me though. My turbo is hitting full boost by 3800 anyways. I can easily drive around the lag.
streetrcrm3 01-20-2006, 05:43 PM Brake boost when you a gt series snail. :)
JBgotM 01-20-2006, 06:03 PM Brake boost when you a gt series snail. :)
GT30R will spool in an STi at about 3700-3800 rpm and is capable of supporting over 400awhp with no problem.
for auto-x, a 18g with some good lovin' from Deadolt will spool under 3k and support over 300whp, its a nice compromise.

I guess I should have specified gt35-42 :evil2 A barrel of c16 is only 300 bucks.
400 whp is hopefully what the IX will do...time will tell...

you can get 400whp on the Evo on the stock turbo with pump gas.
a GT35-42 is way more than needed to get 400, especially with race gas. You are nocking more on the 500 whp range.

You will not get 400 whp on pump gas with the evo8 turbo unless you use alky or race gas via AEM on a not so conservative tune. Most guys with alky on the evo8 turbo get in the high 300's but the magic 400whp on pump (93) on a 16g has not been done yet.
500+ whp with a reflash + alky + motor does sound good though. :)
giterdone 01-21-2006, 06:20 AM You will not get 400 whp on pump gas with the evo8 turbo unless you use alky or race gas
Sorry that just made me laugh. You can't get 400whp on pump gas, unless you use race gas. :stickoutt
Mr.Stiff0 01-21-2006, 10:36 AM what would u guys say if I told u I killed one on the hiway comming back from english town race track in NJ, with my 325is with a SC 2.8 motor/s52 cams track pipe/Borla cat back exhaust running 10psi. The guy had just ran a high 12sec at the track while i ran a 13.6@ 100+ bad launch 2.5 sixty foot. I thought I couldnt take him until my friend egged me on. He was the onlyone inthe car looking like he wayed about 150lbs wet, and my friend and I about 450combined but after 115 up wards it was a rap

Interesting. I helped my buddy mod his Evo 8 with full exhaust with O2 housing, injen intake, upper and lower intercooler hoses, hks 264 cams (IIRC, and those are pretty mild), MBC at 21psi, and dynoflash and is putting down about 340whp. Supposedly its over 400 with race gas at 25psi. This is al stock turbo. With header, FMIC, and a few other little tweaks, I would have expected 400whp to be achievable on pump gas and the stock turbo.
Mr.Stiff0 01-21-2006, 11:39 AM Sound like a beast. I hoped to do some mods this winter, but there is a little set back because of a slight fender bender, but Im looking for about 380 to 400hp to the crank
Mr.Stiff0 01-21-2006, 12:06 PM I also added a 13lbs flywheel, ignition solution coils, 97 m3 gearbox,m3 rear,m coup shifter,stock clutch ect I have to step up on my power & my driving skills because right now i have a big bulls eye on my back due to how my car is running. here are some of my competition. a turbo charged toyota celica race 1&1, mustag cobra 2&0,Evo 1&0,Sti 1&0, E46 323 sc undefeated and the list goes on but all I know this season is going to be crazy
v8killer2pt5 01-21-2006, 09:12 PM I like your style. If I had an STI I'd do the same thing. I never really considered brake boosting during a roll on. Maybe I'm a noob:rolleyes ?

LOL, thanks it's tough modding since there are way too many options. So I have a clear goal, try and be as stealth as possible "LOL IN A STI?" while maintaining a reliable car. Alot of guys in the two Suby clubs I am in have gone above and beyond in the hp department but it just becomes a vicious circle. People claim in many car forums how they are turbo'ed and reliable making a billion hp but that's a contradiction. So far I am over 2 years with nothing but oil changes while making a good bump in power. The only thing I have left to do is some 850 cc injectors to keep the idc's down and tmic with a sensible street turbo. Nothing more in boost and if that at a max of 19 psi. Oh I would'nt kill myself about the brake boost technique, we are not trying to set records. I baby my car, no awd launches and use more finesse than ego when driving. I love the fact that everywhere I go I meet enthusiasts who despite a difference is vehicle choices are always open to a friendly chat. Be safe and enjoy the ride!
JBgotM 01-21-2006, 09:23 PM LOL, thanks it's tough modding since there are way too many options. So I have a clear goal, try and be as stealth as possible "LOL IN A STI?"
a couple friends locally have de-winged, de-badged and swapped just about every panel/visual sign that its an STi (one guy even doing a full interior swap) while putting alot of reasonable upgrades to make over 300awhp and still spool before 3k rpm.
