I've built 3 now. All made between 220 and 235 hp. With NOS, I pushed one to 295 hp. I can't wait to see what the '05 will do - preliminary numbers out of TTS are saying about 250-260.
Also, I think I posted this in the turbo forum, but we didn't blow the engine like we thought we had - we had put a fitting on the oil cooler for the supercharger that didn't allow enough oil flow, and thus caused it to not make power. Once we swapped out the fittings, all was right in the world.
