Re: Stock Pistons

its not so much hp as detonation and runing lean that's hard on pistons.

Re: Stock Pistons

Agreed. A hypereutectic piston can live under some pretty serious conditions if treated properly (minimal detonation). Let ANY piston detonate enough and it'll come apart....I don't care if it's coated with dragon's breath and made by Zeus.

Re: Stock Pistons

If no detonation. You'll end up bending a stock rod before breaking a stock piston. Course if you are in the motor now. Try to do the pistons and rods. Save yourself some time and money in the longrun. Nice to know you got a little stronger lowered end. Plus pulling the motor on these is not the most fun thing to do.

You mean you have actually found something that is more enjoyable than pulling the motor from a sy/ty?

Re: Stock Pistons

Stock pistons are safe to 450hp. Just hope your tuning skills are sharp. Forged will give you some slack. Think about it. The cank and rod bearings usually go first.
