We have ran more than a 250 shot on forged pistons,stock crank and rods and be reliable, but the tune up has to be right. On my race team we use Cold Fusion Nitrous stuff. They are very affordable and knowledgeable. I haven't ever tried it but I've been told if you run the automotive grade Nitrous threw water it will get the sulfur out.Also most race stuff or street cars only run one pump and fuel line to the front. We also run the push lock fuel lines for there cost,reliability, and ease of use.
