So you are saying 6psi on a stock 5.3 motor is only worth 60 rwhp?

 

I average 20 rwhp per psi w my stock 5.3. I've dynoed NA, 4, 6, 8, 11 and 12psi.

 

Exactly, but according to some, you can clearly see that I'm an idiot and have no effing clue...

Like I mentioned before, from import 4cyl cars to highly modified anything engines...when you add forced induction, results will vary. The op was asking about a blower, someone mentioned long tubes, so I simply gave him an idea of what to expect when having both.

I stand by my claims. To the op, if your stock 5.3 pulls 300ish rwhp stock, then you add a blower and long tubes (at the same time), set at say 6 psi you will be making 420ish rwhp.

 

Im just going with a blower only, im fine with 17.65 hp per pound of boost.
