How are these engines holding up with all that boost against stock pistons? I'm not askin to be a smarta**, but I'm coming from the Honda world (owned an s2k) where the max psi on a stock engine is around 7 or 8 (at the most), and never heard of a stock engine that could handle that much boost without shootin a piston throught the hood.
Do they already have forged pistons or something?
