guess i didnt make my point clear,
A good tuner will know how far to push it and if you want to go more its time to go forged
and his set up will make a lot more once it is forged

5.0L push-rod motors were built with lower tolerances than modern motors. With 13+ lbs of boost on a stock motor he's going to have all sorts of issues.

A good tuner can get the most out of a setup. They can't change the fact that the engine wasn't designed for forced induction.

Relying on the turbo to bring the power to where he wants it is going to be pushing it past the limits of the engine. What I'm saying is there's not a safe way to get a constant and reliable 500hp out of an entirely stock 5.0L long block by relying simply on power adders.

Think about it. You're getting over a 300hp gain by cramming tons of air through a small, restricted and inefficient induction system never meant to be pressurized. There's going to be tons of blow by. Failed gaskets. And, eventually something's going to happen where a little pre-ignition occurs and the non-forged pistons are going to shatter.

Also, I'm speaking as someone who has a sn-95 with ~9.5lbs of pressure at maximum, who went to a great tuner. I wish I had gone more conservative on it because of the issues I just mentioned.

throw the 13psi spring in, pull a couple degrees of timing to drop the hp and drive it. done deal
