Default Built 2008 STi on E85 462hp | 496ft/lb

A big thanks to Joe Morrel and everyone else at Goodspeed Performance Lab for putting together a strong car! Dyno chart shows a comparison of our crappy 91 here in AZ versus E85, what a difference!

Car: 2008 STi
Tuner: Clark Turner|Joe Morrel-Goodspeed Performance Lab
Tune type: Speed Density
Dyno: Maha Dyno
Transmission: 6sp
Gear: 4th
Peak HP: 462
Peak Torque: 496
Target Boost: 25 psi
Fuel: E85

Engine/Power Modifications:

Subaru OEM 2.5L Block
Cosworth 100mm Pistons/Eagle Rods/ACL Race Main bearing
Cosworth Stage 2 Cams/Cosworth Ultra Race Dual Valve Springs
Cosworth High Volume Oil Pump
Dominator 2.5r Turbo
Tomei Xpreme UEL Header/uppipe
Invidia Q300 Catback
Ceramic coated ERZ catless downpipe
Tial 38mm EWG
AMR Big MAF intake
Gimmick turbo inlet
Perrin TMIC
TGV's Deleted/Ported
DW 1300cc Injectors
DW 300lph Fuel Pump
Equal Split Fuel Rail Modification


I think that's it for power mods, I'm sure I'm forgetting something here or there as far as power modifications go. I'm maxed out on my air intake, and my IDC is sitting pretty at 82%. Overall, I'm very pleased with the results, especially in our extremely hot summers here in Phoenix.

Is that the 91 octane tune down at 300HP? That looks terrible, haha. The E85 numbers and curves look nearly identical to mine. Within 5 for both HP and TQ with similar powerband. Looks like a lot of fun!

first off congrats on the power, Can you find out what correction factor was used? Im assuming there must be cause a maha dyno is supposed to be one of the lowest reading dynos around. very curious...

The plot says 0% correction factor, other than SAE corrections. It looks like the SAE correction took the number from 406.8HP to 462.5HP. That's 13.7%.

13.7% CF at 99F ambient temp seems really high.

Whatever the correction factor that step function of a torque "curve" has to be one hell of a rush. E85 never fails to amaze.

Could something with how the car was strapped to the dyno cause that steep torque rise? Like it was slipping and then really hooked up? Just curious.

That's what I figured, but was just making sure haha. I am curious to see what these numbers would turn out to be on a dynoqueen, I mean...dynojet.

Yes, the torque certainly throws you back in the seat once you ramp up past 3500rpm, feels so strong it's unreal. And with the EWG screaming, I can't imagine what people must think when I get on it and drive past them, haha

I wouldn't think the strapping methods would affect the outcome. If anything, having it properly strapped down would only show even truer results in the end since all the power is being put down and not lost through tire spinning, wouldn't you also think?

This dyno uses the inlet air temp for correction, not ambient. It conects to the car through the diagnostic port.

You have listed Dom2.5 but the dyno sheet shows Dom3.
