Yes, 92 octane. We plan on turning it up to the 25-26psi range, it should be close to the 600awhp goal we had, as it is averaging 20hp per psi without being very agressive with the timing. I just have to put some mileage on the setup before I really try to push it.
At 482awhp, it really really scoots! I imagine last time I had the car on the road, it was making 225awhp tops. That got me a 13.0@104
