Whats the biggest and then whats the largest thats guaranteed safe shot of nitro that you all have experienced? I have seen up to a 200shot but am thinking that 150 might be the safe but powerful bet.

Lemme know its a stock engine so no special components.

 

125 is as big as I would go, but you need to make sure you have all the right parts and the right tune.

 

Thought you were building a motor and going s/c. Why use nitrous?
