Basic info: 305 cu in chevy[actually 312 cu in] 100% methanol fuel. Rear mounted tank. Most are using a K/W 400 pump. Using your calculator, It shows approx 46% of the fuel going to the Engine. 8 nozzles with .025 or .024 dia. The main is shown to be approx .085. When I enter a KW300 pump, the numbers show a .062 main. and a fuel pressure drop of approx 20 psi. The amount of fuel to the engine also increases to well over 50%. These engines due to restrictions produce approx 520 hp max. Also how much do you think a Fuel filter between the tank and pump affects the ability of the pump/system to function as calculated? Thanks Al
