I have mahle pistons and rings what is the biggest shot i could do. The rings are gapped for nitrous. And the crank and rods are forged callies and compstar with 4 bolt mains. It is a 12:1 383 that is built great. i put down 434 rwhp on stock heads and a smaller cam.

Don't see why you couldn't run a 200 shot all day.

Why don't you call the piston manufacturer and ask them? We'd all just be speculating.

Don't know if it was the same exact piston, but a buddy of mine used mahle pistons in a LS1 engine and he said they reccomended nothing more than a 200-250 Which generally means you have a small window to go a little bigger but not much. Like if somethings rated at 500lbs tq, then it will probably hold 550 or so.

That's called the Factor of Safety. FS is used all the time in engineering, but you usually don't want to exceed it. Let us know what Mahle says about it.
