Nitrous and Fuel Question - please help!
Ok so i currently have a stock in-tank pump and am spraying 100. I'm looking to spray around 200. Which pump is best for me? I'm kind of lost here as far as choosing the right pump.. any help is greatly appreciated

You need x amount of fuel to support y amount of HP at what ever BSFC for a N2O shot.
So you have to size the pump to support your current engine hp plus the n2o hit. The 255lph intank pumps will flow 67 gph. 6.2 lbs/gal makes for 415 lbs/hr.
A guess of BSFC of .6 lbs/hphr so 415/.6= 692 hp max w/o any reserve for reduced voltage, used fuel filter, or weak pump.
