cast> 25-125h/p is considered safe ive ran 175 on a good tune for over 2 yrs on a set of cast pistons They broke on 250h/p

hypereutectic> 75-150h/p is considered safe

forged>Ive seen up to 300h/p worth of n2o on stock h.o pistons with a good tune.Good aftermarket pistons and a safe tune and supporting fuel system will make or break it.

Your fuel system will make or break it as will the tune.

Very true about the fuel sytem and check the A/F ratio. THe sytems are normal safe but I've seen them be lean.

Agreed. Get yourself an AFPR and a good guage as well.

I would try to find a dyno or read the plugs after the 1st easy pull

sounds good so i 125 shot would prolly be the best maby 150 if all checks out good and an air fuel ratio guage would be a good asset any thing else that might make this a lil more safer and reliable
