Need higher octane? Ok I've decided to go the nitrous route. Question is I want to spray a 150shot. Now on a stock motor I know that I need to change injectors and fuel pump and get colder plugs. How much power would be needed in order to run race gas? I want to run pump gas all the way especially when I do stage 2 heads and cam later on. Will I be able to use pump gas with heads, cam and the 150 shot? Maybe even increase displacement when I forge the internals. Can race gas be avoided for all this power? This is for an A4 daily driver. Thanks in advance.

1. You can spray a 150 dry shot on a stock motor by changing to 28-30# injectors and bigger fuel pump, and run 91-93 u/l octane.
2. You can spray a 150 wet shot on a stock motor by changing to 28-30# injectors and adding a second fuel pump, and run 91-93 octane.
3. You can run 91-93 u/l octane safely on the street on a 11:1 motor. Call your local VP Fuels distributor about matching higher octanes to higher c/r.
