Dont Half the Companys selling n20 say stock internals (with fuel system up grades ie. pump, injectors, regulator, and stuff like that oh yeah and a air/fuel ratio gauge) will be ok just do it smart???
my dad has a 250 shot of n20 on a 700 hp with dyno sheets and a 10.11 time slip from Rock falls WI. and I have a 10.77 slipmalibu and I dont think he's even ran it with n20 yet and that beast is built
and that thing is really safe just built up right...
