We received the ITG air filter today, along with the C12 race gas. The car had previously been mounted onto the dyno in anticipation, so we started her up.

We got her to pull 345.9 wheel horse power at 20psi revving to 8300rpm. At that point we started to run out of resolution with the factory 2004 WRX ECU/MAF sensor, so we left it at that. Eventually I’ll use an Autronic ECU with speed/density. From there I expect to pull in the 425-450whp range.

I’m quite happy about the power levels. Double the power i had in January, with tons of potential for next season. I’m also super excited to hit the track on thursday. 345 whp is DOUBLE what my previous engine made for power. It should be interesting at the track, with my new black beast and Bills Baby Blue spaceship.
