Motion Lab Tuned 2004STi 357WHP/407WTQ FPGreen w/ supporting mods on 93OCT
Shop: Motion Lab Tuning
Dyno Type: DynoCom FX5000-AWD Temp: 55F Boost: 23psi Fuel: 93OCT Target AFR: 11:1 SAE Corrections: Default Corrections Peak HP at RPM: 357whp @ 5600 RPMs Peak Torque at RPM: 407wtq @ 4100 RPMs Transmission: Stock 6 speed Gear: 5th Engine Management: Opensource Engine/Power Modifications:
This was a 2004STi from a few weeks ago that we finished up rebuilding the cylinder heads. He had coolant getting in the oil, so we ripped it out and dug in. The motor had been rebuilt about 10,000miles ago, but didn't upgrade from the OEM head bolts. They only rebuilt the bottom end with OEM rods, fresh bearings, and Mahle forged pistons. We ended up doing one of our 3-angle valve jobs and re-assembling with some slightly thicker Cometic head gaskets and a ARP head stud kit. We also found the up-pipe to be COMPLETELY broken in half at the flex bellow which is how we ended up with the high quality 321SS Perrin up-pipe. That free'd up some extra torque and better spool in the mid range. Now the car is running tip top, making more power than the first visit on the dyno, and holding more power up-top with the changes that were made.

That's good spool and lots of torque for non-E85. What's your take on the top end?

What are you referring to in the top end? Its still OEM cams and valves so we anticipated power leveling off even though this turbo can keep the boost up in the top end. Thanks, Alex Goodwin [email protected] |

I had similar results with a lot less motor work. Did 420awhp and then 410tq on a fp green. Ran out of injectors.

why 5th gear?
Is the boost plot wavy or is it just me? |

I thought the same things.
More importantly I am curious about this statement in bold: Quote:

We were testing with the dyno mechanically coupled using inertia only. 5th gear is the best for this style testing due to the gear ratio.

This is an OG green which if I remember correctly were rated at 49lb/min.
