hypereutectic pistons

mee_doo · 01-29-2002, 08:03 AM

I was wondering how well a hypereutectic piston is when running 10 lbs of boost from a turbocharger. any input on these types of pistons would be appreciated

A friend's stock bottom end 93' made 411 rwhp from 10 lbs of boost. I wouldn't recommend 10 unless it was intercooled and had a professional tune though.

i'm running 490rwhp @ 10psi with the stock pistons. i did get it tuned on a dyno with a a/f guage.

I would like to add too that unless you run a set of aftermarket heads I doubt you would be able to run 10 lbs all the time unless you had a mixture of race gas. Unported stock heads could handle about 8 lbs for everyday pump gas, but you still might see a little detonation unless it was professionaly tuned.

i know a guy running a turbo technologies kit on a bone stock motor(downs intake) and he runs alot more boost than 8psi..how much boost do you need to get a 225hp into the 10's???btw the car is DFI
