Nitrous Question

4.7L-stang · 03-19-2003, 03:07 PM

I have new cast pistions that I just put in (the brake in period is killing me!). I really don't want to tear the blook down and go through the brake in again to install forged pistons. Will I have a problem running a 50-75 shot of NOS (modified NOS Sniper kit), or should I just forget it till I get the forged pistions.

With a proper tune, cast pistons will hold up fine all the way up to 150 or so. After that is gettin a little too close to the edge. After all, its not really the amount of NITROUS or how much boost you are running on why cast pistons aren't good, but when you start running higher boost and more nitrous the tune has to be alot better to keep detonation away, which is what kills the cast pistons.
