I know this question as probably be asked before, but I'm having trouble find anything with the search function. So, assuming that I have a stock B16 in good running condition, How much NOS can I safely run ? 65 shot...75 shot..???

 

you can probably get a way running a 75shot but i would stick with more of a 65 shot. Remember you also got to increase fuel that is going into the engine. the more fuel mixed with adequate amount of nos is = to more pwer
