Well I have a centrifugal compressor on another vehicle, and although it makes 12 psi right before it shifts, at near redline. When it upshifts and the rpms come back down, I'm back around 5 psi, so yes my max boost and threfore max power is around redline and yes at that point the vehicle rips, but after the upshift, slug.

And comparing this Procharged 12 psi to my 11 psi eaton on my Lightning, wich covers a much, much broader rpm range, the Lightnings average power is much higher, and the Procharger is on a stock N/A motor with more compression as well, and there is no comparison.

Now if the op mentiones a positive displacement blower with the same boost, I would have guessed the Mach 1 would pull away with no problem.

I'm just basing this from my experience from centrifugal superchargers, they're great at redline but how much time is spent at redline even at full throttle?

Her's one more scenario, I floor my procharged 5.4 liter at say 35 and it downshifts into second gear, my rpms are at 3500- 4K and my boost is at 6 psi at best. I floor either my Lightning or 04 Cobra in any gear besides a complete bog rpm and I'm at full boost either vehicle, who wins this war???
