bigtommy... to explain quickly
when you run nitrous, if the engine goes lean (not enough fuel too much air/nitrous) what happens is it will burn holes through stuff
basically, when you do a nitrous setup right, you have a 2nd fuel setup (pump, lines, etc) that feed the extra fuel when you activatie the nitrous shot. that way you are sure to not run it lean. running it lean with the nitrous is a pretty sure way to blow her up quick.
