All day...

They should be fine with a 100hp shot. Hyper pistons aren't nessicarly that much weaker then forged pistons. Forged slugs are just much more resistant to detonation.

I wouldn't be scared to put a 150hp shot on my notch which is a 93 (aka hyper pistons). I actully plan on doing just that before too much longer.
