Hypereutuetic pistons and nitrous??

No. The ring gap is specific to what you will be doing with the engine. The United Engine website has a chart that breaks it all down. Hypers can be used fine with a 500 HP shot from a Pro Shot Fogger as long as you follow the ring gap and piston clearance recommendations. Best thing to do is call United Engine and speak to Marco. He can splain it a lot better than certainly I or probably anyone else here. Pistons don't just "explode". They may "fail" as a result of something else. Running lean is the biggest enemy of a hyper piston, though.

Whats confusing to me is that I have seen plenty of guys who put on 100 to 150 shots of nitrous on motors as an after thought and hadn't clearanced the rings for it and had no problems. Not only that I've seen plenty who didn't have a built in retard and didn't have problems??????
