Boost Fuel Question
I would like to go to a 3.25 inch blower pulley, I currently have 42# injectors with GT500 fuel pumps. Should I have enough fuel to handle the upgrade? I will run on Dyno checking air fuel ratio. I know by upgrading injectors all would be fine, but if it isn't necessary, I do not want to at this time.

Brenspeed uses 41# injectors with their 3.25 pulley. You will be okay with fuel, but I would worry about your bottom end blowing with that much horsepower.

It also depends on what your current pump system is. INjector and fuel pump duty cycle would give the real story.
