My blower is the older model P600 that uses engine oil. I have installed 2 P1SC units neither customer was to interested in dyno numbers though (spend all that money and no dyno?). The new P1sc is quieter than the P600 and the P600 is quieter than the old Vortech V-1.

I paid $2500 used for my blower with a 3-core intercooler.

All of ATI Hp claims are based on a stock motor. I did not have a stock configuration when I purchased my blower but I did have a common GT40 head/intake/E303 cam package. I think FRPP puts flywheel power at 340 for the GT40 longblock package w/E303. Correcting my GT-40 dyno for flywheel would net ~ 470 HP.

This would only be 38% gain but there are some factors to consider for this comparison. I did not have the intercooler hooked up, which requires air flow to work well anyway. The motor had a dead cylinder.[Number 8 cylinder lost its compression ring and part of the piston from an earlier incident and detonated itself] The ensuing detonation caused the head gasket to lift at 5000 RPM essentially ending power production at this point.

So in a worse than worse case scenario ~40% would be had. I think my numbers are very inconclusive except to show that I gained (theoretically) 130 HP with a lame horse.

I am about to do new dynos on the "new" motor in naturally aspirated and with the blower. There is really no good way to test the intercooler except with the marine cooler (like ATI did for their tests) so any blower dyno numbers are going to be conservative compared to real world road #'s.

The faster you go the more air flow to the intercooler the more effecient it is. So keep this in mind. Also the kits are not that hard to install and their belt tensioners are top notch. No slipping drive belts.
