One thing to point out is that if you go as deep as P72Ford has illustrated, you're making serious power, as even a crap turbo setup on a 5.slow would satisfy most people. 500ish hp is generally accepted as block splitting territory for the 5.0. Some split them sooner, others later. I don't know how boost plays into this because even though it sends dynamic compression through the roof, the revs of a boosted engine are generally lower than a balls out N/A build and I'm reasonably certain the revs are what shake that bottom end loose.

Detonation is what kills blocks at 500HP and lower. Detonation is what will kill an Explorer engine at 4lbs of boost if you mess up. Indepth knowledge of the physics is not necessary to make 500HP from a 302. Having the common sense to pull timing and invest in proper fuel and boost management will go a long way.

I was using the 14.7 because it's atmospheric pressure


Thanks a lot. These posts have helped me immensely, and I'd love to hear any other thoughts that anybody has on either turbocharging in general or folks with experience having turbos on a 5.0

What would you say is proper fuel and boost management? A high flow system and an AFPR I would think, with the computer tuned properly. I'm more curious about the boost management.

Detonation kills ringlands and pistons, but blocks? Why would the block let go before a piston from detonation? I've never heard that before.
