Not hardly any. My goal was 525whp and 450-475wtqish. I'm at the torque level but not HP. We did a pull at 11.8psi and it hit 518/479 but it leaned out a little up top so we dialed it back a half pound and called it a day (503/465).

Is anyone actually hitting the end or just getting close to it and stopping? Once I started nearing the end, every .01v took a lot more air and when it looked like it was going to max out, there was still a lot more power left. I did eventually max them out just before I stopped going higher anyway.

I'm maxed out. At 11.3psi I'm at 5Vs around 7200-7300 rpms. When I log it in UpRev one MAF sensor reads 5.0 and the other is like 4.95. I can't say which one is maxing because the chart in UpRev doesn't differentiate.

Phunk - I also think it's about return fuel setup time. Need to get on the phone with you and discuss a few items to determine what's the best direction.

I have the same hp/tq goal for my car, 475hp/425tq DD and 525hp/475tq drag.

Anyhoo, back to the VSR build.
