5.3, boost cam, w/MP70, 10psi, 6-speed. Will I see 500Hp at the wheels? My goal is modest, I would like to see 500hp at the wheels. What PSI do I need to run to see that number. BTW, all aluminum 5.3, 243 heads, LS9 injectors, dual 255 pumps, LS6 intake, 85mm TB, 2003 Z06 exhaust manifolds, small baby cam (212/216 on a 114 lsa if my memory serves right). All running through a 6 speed. Will 10psi get me there?

40hp cam ??
10hp LS6 intake
10hp cat deletes
5hp better flow Z06 exhaust manifolds
5hp PS delete
So long story short, even though the numbers above are higher, I would say 370-375 crank would be close.

I think it would be close, 10psi im going to guess 450-475whp. My friends 5.3 w/ a MP70 on it , stock 99 LS1 cam, 317 heads, stock LS1 intake, custom headers, 6-speed, I was guessing 550whp on 15psi on 93 octane.
We switched it over to E85 and then the new RAM powergrip HD couldnt hold it after that.
But I was tuning it and we started off at 5psi, then 10, and then 15. It was quite a noticeable difference going from 10 to 15psi.

boost and power It made about 1400 HP with about 20 pounds of boost...GT4788 will do that.
Its really about cfm of air the device will put out......that dictates the power

Here's my dyno runs with my old LQ4 with stock 317 heads, mild cam with a mpt76 turbo custom front mount...
6speed, 4.10's, 10 Bolt, 28x13.5 Tires, Spec 3+ Clutch
9psi - 565rwhp/556rwtq
15psi - 786rwhp / 7xxrwtq (don't have dyno sheet)
I was TOLD by the new owner of my SS..
20psi - 866rwhp ??? I havent confirmed that yet tho.

Not to hijack the thread but if a PT-88 will make that much HP with a 290 CID motor wonder what a would a F1-A pullied at 8-12 psi do on a stock 5.3L?

BTW, no offense to the guy that posted that, but I doubt it made that kind of power on 20psi, maybe 30+.

To a degree that is true but its all about the variables. I had a 252 Cubic inch six cyl that made about 290 HP...in NA trim
It made about 1400 HP with about 20 pounds of boost...GT4788 will do that.
Its really about cfm of air the device will put out......that dictates the power
