Default Akuma Motorsports 05 STI 2.5L+GT52 332/302



We had a chance to tune one of our customers STi's today with a GT52 on it. He added a bunch of other supporting mods and wanted us to re-tune the car to make sure everything was running right and also seeking for more power. He's on the road as we speak so he will chime in later to let you guys know how it felt. Blow is the mods list and the dyno graph. Enjoy!

Looks like a good build, I don't know enough about the turbo to know whether it's putting out a good amount of power or not. What was it running previously?

Yeah please don't get caught in the numbers game.. The car is running very strong and that is pretty good power considering what our dyno reads! Keep in mind 340awhp in an evo put down an 11.9 pass with a 116mph trap!! I'm sure the owner will chime in soon... If his stock clutch held enough to get him home lol

You would cry!! We don't have any 100% stock numbers but a stage 2 Sti with an off the shelf map puts down about 220-230. If anyone is in the area we could setup pulls at a discounted rate for a bone stock vehicle

Oh I wasn't doubting the power. I just allways like stock numbers for an idea of how the dyno reads. John knows his stuff no doubt about it , 100 horse over stage 2 is pretty crazy.

I agree. All hail the heart breaker.

My buddy had similar setup, running a 50/50 windshield fluid mix and Hydra though. He made 400/400 on a Dynojet at 21psi. IIRC it was about 380/370 without alky.

Just for those that like #'s and I know Ron's got a log the size of a Webster dictionary of power made by every turbo and setup out there.

I'm really glad you are enjoying your new found power. That power band should make a very very fun street car. And yes your clutch will be in soon
