can my motor take it?
I might be buying a 12# p600 procharger and I would like to know if you guys think it would be safe on my motor. The thing that has me scared is my compression is already 10:1 and my pistons are hypereutic(-2 for spelling). Now I know Im not gonna see 12#s but with my mods how much boost do u think Ill see? Will it be safe? Also will my fuel system be up for it(255 lph walbro pump and 24# svo injectors)? Thanks for the help.

As far as I know it never was. It has the 12# pulley on it. I believe the best that was seen was 9 on a 350 with several mods. So what do u guys think?

I think it may still blow head gaskets without a cam that has some overlap to bleed a little cylinder pressure and at the same time at least give some scavenging affect.

That hot cam is so awsome at building cylinder pressure to an almost supercharger level on normally asperated engines, that it will most certainly when combined with the high compression ratio, and the boost, pop head gaskets. I know it is a sad deal, a 9# pulley might help alot. fuel quality and timiing will be very critical and control of them may not guarantee against failure. I would recommend premium with additive ALWAYS and a crane HI-6TR (Timing Retard). The MSD 6BTM (Boost Timing Master) seems to be the only MSD product I have encountered that has a quality control problem and may be a design defect that causes it to fail to retard timing under boost some underterminate time after installation. IF it is any consolation there are blowers on the high compression LT-1 (10.5:1?) and the LS6 and LT4 (11:1?). the intercooler is key. when considering them and if you dont daily/commute drive this car you might be able to keep the pulleys you have.
