I have the Procharger and it is going on a newish 383 (350 with a 3.75" stroke). I am guessing compression will be around 8.2 - 8.5.

Iron heads (993's) and an aftermarket TPI (large runners).

There are two cams (flat hydraulic tappet) from Crower. One is rated at 5-10 psi boost. The other is 10+ psi boost.

I'm not sure where the boost levels will be at, but I want to run as much as possible. I'll stop at 15 psi, maybe.....LOL

This is going on a boat and I'll be adding a intercooler (air to water) soon after.

What have you guys run? I also need a descent idle from the engine.

Thanks

 

i run a fairly large cam on mine and i run
14 psi.
you can find it on my web page.
