| Supercharger pulley advice needed
Ok i need some advice, I have 93 lightning that is for the most part stock, except for the powerdyne supercharger which has been with the truck since 94 or 95 im not sure, i didnt put it on. The truck Has 187,000 miles on it, the supercharger has a 6 pound pulley 3.13" diameter i think and 2.93" and a 2.70"
pulleys are available and each are suppose to add 2 psi to the previous one with would put it at 7psi and 9 psi. I looked at the powerdyne site and they gave some info about upgrading something like that and im sure i exactly want to believe it (they said that it isnt boost that damages an engine its the rpms that does) which is true to a certain extent. Does anyone know if i can safely run the 7psi pulley or even the 9psi? I relize that to be more sure on this i would have to do a compression check or even a cylinder leakage test. But i dont go out and race it everynight and beat the crap out of it.
Oh and the s/c has been rebuilt once since it has been put on with ceramic bearings. |
