What are the best pistons to buy for nitrous application? I have a h/c car and want to spray a 100 wet shot. I have been advised against it as my stock shortblock won't handle it. Any advice is appreciated.

 

i have had great luck with dimond.
i run a dimond shelf pistion in B-Mans car with a 125 and no issues knock on wood, she is doing great.
10.4 @ 129 3700 pound car!

 

Stock pistons will work fine for that. If you are intent that you really need them, then I 2nd the Diamond name.

 

Third for the Diamonds, both off the shelf and custom N2O pistons. In all honesty you shouldn't have a problem on the stock bottom end of a H/C car and a 100 shot, as long as the fuel system is up to the task and the tune is good.

How much nitrous are the off the shelf diamonds good for? I'm hoping to do a 250 shot(total) 2 stage on them.

 

I want to say they are "good" for a 200 shot. We've and I'm sure countless others have far exceeded that with no issues, but like always your results may vary.

my old pistions where off the shelf but coated, and i wacked them with 300 for a long time!

 

This is good to hear. I have been contemplating if it is worth throwing in some forged pistons for a h/c engine with a 100-125 dry shot. Sounds like I will just leave the stock short block alone.

 

usually the stock pistions are ok, its the rings that go bad

 

At what power level do rings give out?

 

i have seen them go with stock cars all the way to 600-700 rwhp! depends on alot of things, tune, heat, mantinace ect ect
