Default Getting a SuperCharger, but how much psi?

Based on the few mods below, how much psi do you recommend getting. I plan to get some trickflow heads and a b303 cam soon. Any comments welcome. I'm getting a Procharger w/ intercooler. Also injectors and a fuel pump.

Thanks.

I've seen post that say don't go any higher than 9 on stock internals but I can't verify how accurate that is.

the tranny will probably go before the internals, i'd start out with 6-7 and work your way up. one of my buddies crapped the tranny with similar mods puishing 8 psi, then swapped over to a gforce and upped the boost to 9psi, he blew that one too, had it rebuilt and blew it again ...he then swapped over to a TKO600 and has been running 10psi with no problems, he's planning on doing the internals soon though, doesn't feel safe.

I had a friend with a 94gt.. with h/c/i and a procharger at 12-13psi for over 20k with no probs. He got a good tune which i think helped him out tremendously..

8-9psi is a good place to start. thats what i did when i got my sc. for fuel im running 42# injectors, 255lph in tank pump and the t-rex inline pump that came with the kit. i think the e-cam would be better for a sc but some one else should comment on that cause im not sure. if your going intercooled, you can run a little bit more boost but not a whole lot. couple more pounds

The b303 cam isn't blower friendly, the F303 is however.
