dont get to caught up in a PSI number as that means nothing. my old 4.8 on 9 psi did over 500 rwhp without breaking a sweat.
if you have a power goal in mind then just do what it takes to get that number, it may be 6 psi or 15 depending on the tuneup and parts chosen
very true!!! a well setup combo will make alot more power at 5psi than a junky setup will at 15... boost doesnt make power, air flow makes powerQuote:

It's obviously not the perfect combination for boost, but it'll work. Your compression ratio is probably around 10:1(assuming you're running an LM7) and that is about the same as the L33 HO 5.3's that many people have had great success boosting.
Pick up the new Hot Rod magazine for a read, they had a junkyard stock bottom end 4.8L with heads, cam, intake, and twin turbo's lay down 1200hp at 26 psi and held it fine
That's probably my favorite article I've read. That made my mind up on doing a turbo on my truck. Now just to save up and piece it together. To the OP, you can always get a set of 317's off someone for pretty cheap and sell your heads. That would drop your cr a good bit. And really if you want you can get a ls6 cam for cheap too.Quote:
