Stroker MPG

[Cheromaniac]

Not sure. Check back next year. I'm estimating 325-350 hp... if it doesn't detonate itself to death first. The stock cam maybe a bad choice here.

Nice, that must be crank hp. Any idea what the rear wheel hp might be?

325 crank HP is a reasonable estimate for a modified poor man's stroker with a 6psi supercharger. Detonation shouldn't be an issue with a modest 9.2:1 CR, good quality gas, colder plugs, a fuel pump upgrade, a good cooling system, and a proper tune.
Rear wheel HP will vary depending on which tranny (auto or manual) you have and whether you're running bigger, heavier wheels.

The other was some clown on NAXJA.. but he was such that you couldn't believe a work out of his mouth. It has since been proven that the supercharger he was using would not make 12psi on 4.0L.

Yeah I think I know which clown you're referring to.

We also did 18 psi through a stock 2.5....which is heavily based on the 4.0 .

I recall reading someplace that the 4.0L wasn't actually based on the 4.2L, but mostly the 2.5L. The 2.5L was releases prior to the 4.0L.

I know ryan has done a bunch of boosted ones.No failures that i know of with head gaskets.Arp hardware would definitely help if youre going to push the limits.Pretty sure hes done a bunch over 10lbs with no failures.

I think ARP hardware would definitely be a necessity. Eitehr bolts or studs. After that I don't see why the engine wouldn't be able to see higher numbers with the MLS gasket.

a fuel pump upgrade,

This is something I have been considering for my build.

Yeah I think I know which clown you're referring to.

LOL.
