Whats an effective but safe amount of nitrous to inject into an 98' H22 with the following mods: i/h/e fuel rail, fuel pressure regulator, 255 gph fuel pump, MSD (ignition, coil, cap and rotor, and spark plugs)? Im just lookin to run around low 13s but i dont want to mess up the engine. So what would be a good shot of nitrous to inject without puttin the engine in too much danger.

This is the most recent one that nitrous was talked about.......

 

Quick answer: 75 shot.....you can run more, but reliability gets sketchy......And you will most likely run mid 13s with that.....assuming your running street tires
