Most HP/TQ on Stock turbo?

trhoppe · 04-06-2005, 01:03 PM

So we're tuning the STX map at TopSpeed last night. We get done with the STX tune (thats for another thread

) and Doug says "Lets see what this bitch can do with some boost, now is my time to play"

K&N intake
GPMoto inlet pipe
Unorthodox Racing pulleys
Stone Racing header
BPM downpipe into high flow cat into straightpipe
TopSpeed tuned ECUtek
stock, non ported turbo

253hp/271tq

More torque and the same HP as a stock STi with 400 less lbs weight

Unfortunately, we had to pull the map back off the car (back to STX map), but damn the car made some torque.

That sounds about the limit. I remember the company with the downpipe with the cut-out boasted the fastest stock turbo wrx. I think it's horsepower was in the 245-250~ range.

So that's been bested by a good amount then.

Your stx map looks like it's got a little trouble at around 3200 rpm. The boosted plot looks nice.

STX map only allows stock boost control and with stock boost values in all the wastegate tables, it cannot control the spike that comes on from the quick turbo spool. Nothing you can do about that at all.

I am teh confused.You have a Wrx? I thought you (had a Sti )sold the blue wrx to Biggs...

trhoppe · 04-06-2005, 01:38 PM

This is biggly's blue WRX. I'm codriving it this year and have it in atlanta right now getting it ready for the season

I never had an STi, I built one that wasn't mine, but it has now gone away.

Oh ok..Topspeed seems to have their stuff together...You didn't ever happen to dyno the inlet hose before and after did you?

Not w/o doing tuning and other stuff at the same time.

Cool, It just looked like timing was being pulled...

CMJ · 04-06-2005, 01:56 PM

What octane fuel was used for that?

93; just regular ol' pump gas.

Dynos are tuning tools, not phallus measuring devices.

250hp on one dyno may be 220 hp on another.

trhoppe · 04-06-2005, 02:23 PM

Well this is a dynojet which does a stock STi at ~250/250.

Actually for the "boost" run we had the 100 octane, the lower map was on 93 octane.

The dip is because we are not allowed to change or modify any parameters that control boost, so they are left completely stock. Now with them remaining stock the ecu has a hard time controling the boost spikes from an open exhaust and intake. You can clearly see that with the boost control modified the spike is now gone. It was quite fun actually tuning the STX map because of the fact we could not change or raise the boost all power had to be made the old school way with AFR's and timing, a true test for the skills of your tuner.

It's just to bad you never got to drive it with the boost turned up ..

.. I still have the map if you ever decide to run SM instead.

1CLNWRX · 04-06-2005, 05:44 PM

Question for you guys, do you feel that the header played in any part with delivering more torque? Reason I ask is b/c when my car was dyno tuned it was maxed out on one run with 242whp/tq. At the time my car was running a little lean so the tuner stopped there. Do you think that with a stock turbo I would benefit from a header if I went back to get the car tuned? I have ecutek and my runs were done on 94oct. The dyno was dynojet @TurboTrix. I already sold a Vishnu pulley I was going to throw on there so pretty much besides a new fuel pump(already changed my fuel filter after the dyno tune), there is not all that much left to put on the car besides a "CAI" which I am not going to do and some type of header which I am still debating. Any input would be appreciated. Thanks Nice numbers by the way, it does indeed show the tuning aspect of throwing a car on a dyno. I was looking for a little more once my car put down the numbers it did but I would rather play it safe than look for instant improvement.

My opinion is that some of it is definetly the header. Now that is purely my opinion as I have not tested this car w/o a header or have tested a different header on this car. BUT, every car I have seen with this header, has made a great amount of midrange torque. The car also picked up a ton of torque once Doug started playing with stuff. After just turning the boost up it was making like 20wtq less then the final #s until Doug started messing with it more.

-Tom

1CLNWRX · 04-06-2005, 05:52 PM

Yeah, I am still debating on wether or not I should run one. So far the price tag and facts do not make it an easy decision. 1/2 of the people say yes, the other 1/2 say don't bother. I guess it is just one of those things to test out for myself. There was another car there that day though that put a good 10wtq on me and I am almost positive that he told me he had a header on there. Not sure though. Thanks So, time to take the car to the track huh? I plan on taking mine in the coming weeks. As soon as I can find the time away from school and work before it gets too hot. Later

What header is on that car? I feel like I should already know this for some reason.

SINthetic · 04-07-2005, 10:49 AM

QTP put down 249hp and 276tq. But they also backed it up with a 12.7@106 pass at the track. But good numbers, now get to the track and lay down some ETs!

This is an autocross car so it's not going down to the dragstrip. Otherwise, I'd do just that. Besides, we can't leave that boost-happy map on it, only the lower line that you see above. Good job for QTP running the 12.7@106; that's very quick.

Just FYI Biggles....if you ever had the hankerin'....there IS an 1/8th mile strip within an hour of you. Piedmont over in Guilford....right on the Alamance county line....40 West to Burlington, 7 miles from the interstate.
They have "Test & Tune" blocks on Thursday nights and Sunday afternoons. $15 and you can run all evening/afternoon.
Might be fun to get a Subie contengient out there sometime. Let me know if you ever want to go, I'll meet ya there and we'll have some straight-line fun.
