I just finished doing a base breakin tune on JDM-STI'S car. Again we are amazed by what a flat tq curve we were able to achieve with our new motor package.

Peak boost was set at 20psi falling to around 18.5psi at redline. Run was made on straight 93oct. No other octane booster or adder was used. This car clearly has a high 400hp run on just pumpgas in it once some more miles are racked up, and we up the tune to something a bit more aggressive.

Doug did an outstanding job on the motor build. I have no doubts that it will have stock like reliablity. Not many with built motors can say that from all that I've read over the years.
And what can I say about Scott's tuning. Not only is he a great friend of mine, but he is an absolute top notch tuner.
As far as my car goes, I couldn't be happier with it right now. My old set up, FP Red on pump/meth made 435whp on this same dyno running 27psi. And on the street, spool is close to the same and pulls much harder now than before. I mean 455whp on pump gas only with minimal timing and no AVCS tuning is INSANE. I can't wait to break this motor in and run our planned 30+psi. Then the fun will begin.

With a build and tune by TopSpeed I would not expect any less

Great to hear JDM-STi!

Great job! I am extremely impressed at the work put out by Top Speed and when it comes time for a race motor, this is the place for the job!

RR2 Race Block in the works as we speak!!!

***UPDATE***

520WHP/462WTQ at 26.5lbs of boost tapering to 23 at redline.(93 octane and 75/25 meth water/mix) Hydra boost control SUCKS!!! More to come after the AVCR install.

awesome numbers, were you able to tune the AVCS?

Not much at all. For some reason, the Hydra and AVCS don't want to play with each other very well.

Here's a plot with some "highlighting" to show the gap from the .82 hotside to the .63

if im readingf that right thats a big difference.
how did those 850 cc injecters hold up with the gt35r?

IDC's were at about 95% at 450whp range on straight pump gas. If I remember correctly, IDC's were in the mid 70's at 520whp with pump gas and meth.
