star stage 2

[t-dogg10]

ok, since ner is out of business, or raoping people, not so much a good idea huh? well, anyways, im lookin into a star stage 2 kit now, and it says 9-10 psi, im assuming that that is on stock internals, i hope or is that the max possible. . .and if it is with stock internals, what would be a rough estimate that i can run with aftermarket internals?

as always thanks

To be honest Hahn Racecraft knows there shit when it comes to numbers (psi and fuel) you can run on these motors and still br relilable. Now that I've sad that, it is possible to run more, it's just recommended at all. To much can go wrong, bad gas, boost spike, BOOM! Kiss your motor good bye. Check out there website, they are a good example to follow!

That is for stockers, for forged parts you can go as high as you want, until those parts may fail. Prolly somewhere around 700-800 HP.

Yeah on nitro methane...........if you want to build a decent street car, on pump gas I'd personally estimate around 350 to 375whp. Granted that depends on a million factors, but that's what I'm building my car to.

How much power will depond on alot of things what compression,what bore,pump gas, what turbo, what support mods, but hahn has a 420a whit a 20g on 116octane doing 475 to the wheels at about 25psi I think thats right but just check out the site but who knows what compression they have and its not bored!

Basicly, unless your rich, you prolly won't come close to max power for those forged internals.
