Yeah, it really is. They call it the "heartbreaker" for a reason.

I'd love to get it to the track, but it wouldn't be a good judge of the car's abilities as I have never run a 1/4 mile before.

The shop owner guessed, based on his dyno, that the car put down around 360 at the crank.

Looks good, but the torque curve looks a little funky from 3200-4200, and you should be seeing peak torque (or nearly) almost 1k RPMs sooner.

Tony (the tuner) said he was surpised that the torque curve was so far to the right, but he said the numbers were all correct. He's the one who tuned the Car and Driver 09 wrx so he's pretty good at what he does.

I'm not sure what would cause the torque curve to move over like that, any ideas on what out of the ordinary might cause that?

Hella lop-sided turbo. IMHO, the TD06 is too big for the 18G, even more so with a 8cm^2 housing. Not trying to bash your setup, I'm sure its a blast to drive.

Don't worry, no offense taken. I just wanted to make sure that it didn't indicate a problem. I have learned I just have to drive it a bit different than the stock TD04 when I want to get on it.

It certainly does make getting on the freeway a ton of fun, and the amount of pull it still has in 5th gear blows me away.

IIRC stg2 '04-'07 STi puts down 240-260whp on that dyno. My '05 WRX put down 198whp/202lb-ft on an STX auto-x map. I think the tuner, Tony, put down ~350whp on his own STi and it was running somewhere in the 11's in the 1/4 mile.

When is the targeted 22psi seen? The number don't look bad when considering what a stock STI puts down on that dyno. Just an FYI, I had a blouch 18G 8cm^2 turbo on my 02 2.0 WRX and hit peak torque (20psi) at 3700rpm. Did you adjust the wastegate actuator any?

Great numbers in comparison to a stg2 sti on the same dyno, but Im with the others on your late torque curve.

I didn't do any of the adjusting. I had the setup installed completely by the shop that tuned it. The tuner did say however that the backpressure was keeping me from seeing better numbers which were possible. He said that a catless DP, and a better flowing exhause would help (I have the spt) He also mentioned an external wastegate would get me better numbers.

I do wonder what kind of differences I would see with those changes. I'm still in the learning stages with all this stuff so I will admit I don't totally understand all of it.

EDIT:

As an additional thought, what kind of difference would one expect from the 8CM^2 on my turbo vs the 7CM^2 on your turbo, would that push the torque curve to the right some?

With that turbo and the volume of air you're pushing you would probably see 10-20 whp increase just from the exhaust change. Adding an external wastegate might get you another 10-20 and it also might help get things spooled up quicker as the ewg provides better boost control.

I think DuckStu is making just over 300whp on SI's dyno with an 18g in his STi, but part of that is a built bottom end and different heads.

you're also knocking/pulling timing after peak torque, and your 7cm hotside is out of gas before 6k. 7cm vs 8cm definitely makes a difference.

Ya, up top the MAF is maxed out, stock intake, so we had to ease off the boost. Pretty drastic drop in power up top.

The TD06 is much much larger than most give it credit, its the same wheel Greddy puts on there T67(TD06-25G) which has similar capacity to a GT30R. Just think some of these turbo vendors made a TD06-16G, that turbo is joke. A TD04L-16G would be a better fit for the compressor.

All these 2.5L guys have been believing the hype for years that they 'need' the TD06 which in fact a TD05H WILL make as much power on a 2.5L & more than likely have a better powerband due to quicker boost response. Granted the TD05H boost will fall off a bit more up top, however there's other ways to make power other than just boost.

I am not trying to be a jerk but I'm going to call it as I see it. You have a 18g car making less horsepower then a vf43 car. Something is wrong.

280awhp on 18g is not good numbers. I've yet to see a single STi make less then 300awtq on a stage 2. It's about 75whp off from what it should be seeing. Is it running stupid rich or something the boost is there.

if a 265hp 09 makes 209 thats pretty damn close to what a dyno jet puts out. I would look into whats wrong with the car.

Testes1010 on a 2.5 peak hp wise the td06 will make more up top. I don't have the dyno charts in front of me but I am pretty sure that it does spool later.

I have to disagree here. A dyno jet does not put a stage 2 sti at 240-260 whp. This is a pretty low reading dyno.

Why is it every time someone has a less then expected power return its because it was such and such dyno. . You gave the benchmark and I have local 09 dynos from the dynojet at IPS and they match.

If your happy thats what matters but with that boost level you should be making allot more low dyno or not.


Thats a 2.0 with a vf39.

Stock STi 215-230
stock 2.0 165-180

But what do I know. BTW it was not tuned off the sniffer it was off the lc-1.

The results were not at all less than expected. I asked the shop owner when I was planning the build, with the specific setup I ended up using, what he expected my power levels to be. He said on his dyno between 280 and 300 whp which equates to around 360 at the crank. 285 fits right in there. He told me both before after the tune, catless DP, less restrictive exahust, and an EWG would get me past 300 on his dyno. It is precisely what I expected.

I am not trying to be combative, and am admitedly a newb at this, so correct me if I am wrong, but the dyno plot says E85, I was under the impression that yeilds significantly more power than 93oct.

35whp and over 50wtq by running e85 on my car with a vf39"Smaller then a 18"
I make 300awhp/28xawtq on 93 octane at 19lbs
I make 335awhp/333awtq on e85 at 22lbs

360 at the crank is low as hell for your setup is my point. You should be seeing closer to 360whp. To each there own. enjoy your ride. I just hope something is not majorly wrong with it.

I think people can't get around these facts...

1. low reading dyno

2. CATTED downpipe, and SPT exhaust

3. big hot side

All equals much worse spool and maybe 10% less power all over.

This argument will end as soon as the OP makes his first 1/4 mile. Trap speeds will shut people up.

Oh, and on this dyno, subaru's max out their maf's at 330whp.
