Hi, I'm just planning my high boost build, and was wondering what the best pistons for 25+ PSI are.

Thank you.

25+, if your serious call up any of the big manufacturers and they can set you up. Diamond, Manley, etc.
You better have 6 bolt block/heads, studs everywhere, etc.

Remember psi is just a number and efficiency of the setup is more important. What are the power and et goals?

i use custom JE's for that kind of power-shelf pistons aren't made to withstand that kind of abuse

I would like to get into the 8's, maybe 7's. and it would be a strip car, but will be street legal if possible.

JE with some stout wrist pins. Our previous custom made diamond pistons were crying.

what do you mean by crying? Also, what would be the ideal CR with this much boost? it will have meth injected, 93 pump gas.

The pistons just weren't happy and we will leave it at that. As far as compression maybe 8.75 to 9.2:1, pump gas + a ton of methanol.

This will be somewhat unrealistic considering your goals.

E85 and LOTs of injector and pump capacity will help.
