if your gonna run 15psi on a stock bottom end 2v without a dyno say by by motor. even with just 10psi and no dyno tune its just a matter of time
good luck

p1sc cannot reach 32 psi!!!!!!! Go ahead and call procharger and ask. the most ur gettin out of that is 12 psi. it has a cut down impeller. the website stats says it can create 32 psi, in an enclosed environment, not in amotor. sorry, but u WILL have to upgrade to a d1sc. go ahead and call procharger if u dont believe me.

Your a fool running around on an unchecked 10 PSI tune from ATI. You simply must get on a dyno/ af meter to make sure the tune is ok or your just playing russian roullette.

I would never run a tune that came from ATI/Paxton/Vortech/KB or any other company that does not specialise in 2v in particular and offers a custom tune for your mods. These engines are simply too weak detonation wise... one det and your done.

The PS1C will tap out in the 4xx range.

true, but he's going to need to boost at least 20 lbs for 650 rwhp
I don't agree at all... MPH has stock heads/intake cars making almost that on alot less than 20 PSI... forget itwith a H/I package....

With a H/I package the car above probably would make close to 700 WHP (if notmore)at the same PSI on that novi 2000 setup.

DONT AGREE AT ALL, HUH?? well, that saleen didnt make 650 rwhp, it made 600 with 17.5 psi!! Thats close to 20 already! And with the the general concensus that for every pound of boost = 20 hp, then it would have taken 20 psi excactly to get 650rwhp, which is what i was saying!! but 20 psi is just above the efficiency range of that supercharger, meaning, that the air at being compressed to 20 psi, is very high in temperature, so it would have probably taken over 20 psi on that car to get 650 rwhp! Now im sure that u will find another lil thing to prove me wrong, but i really don't care. And since when is "17.5" a lot less 20?????? On a side note, however, that car was cammed.

Guys, were getting away from his ?. You can run 10lb of boost at around 400 rwhp only with a VERY GOOD TUNE or it won't last very long. The bottom end of the motor, mainly pistons and rods won't hold together with anything more. Don't know if you have access to a dyno where you are but its probably the most important piece of the puzzle to do this correctly, good luck.
