Thread: Would like some feedback on Pistons...

I believe the FM's are considered OEM replacements. While I'm not running them specifically, they'd likely be a good stock quality replacement.

:-/ Hummm... so they are not exactly something I want if I am planning on running a lot of boost through my motor... I wonder that kind of HP humbers they can support without going kamakazi...

Well.. most guys run stock pistons for a long time w/o issues. Guys like Todd Allen from Intense had a stock bottom end with around 460hp w/o issues. Killing pistons is more about the tune than it is about the amount of boost.

IIRC Darkhorizon is pushing some healthy amounts of turbo boostage through a stock bottom. (At least I think he's running a stocker). But then turbo boost is typically cooler in it's charge than SC boost.
