I have Diamond part #11502. This is there street strip piston, I cant find what material it is made of but its either 2618 or 4032 aluminum. I think its 4032 but am not for certain. Top ring is down .250". What size nitrous shot before problems with the integrity of the piston becomes a problem? Is 250 safe?

 

I would think a 250 would be fine.

But its best to call Diamond direct.

 

ok thanx, I guess i need to change my question to "what is the highest anyone is running with this piston right now?"

 

Im sure the pistons are good for a good dose.Your tune up is what kills the pistons.

 

i agree 100% but you cant make a stock piston handle 600+.

 

why not....I have done and seen plenty of stock pistons run at 600+ rwhp with close to 300 shots. Unless you were saying a 600 shot...in which case....your absolutely right...lol.

 

what stock bottom ends over 600 hp?? where..

HEHE and thats onle with a 175 shot.. 250 to come

 

lol alright lets try to make this clearer, What will this piston take with a constant ping of 2deg knock?
