Subject: Re: Are the Bosch III's too big? by Matatk on 2011/4/4 3:20:42 http://mustangpartstech.com/FuelInjectorMath.html http://injector-rehab.com/shop/Injector-Size-Selection.html Injector size = (HP x BSFC) / (number in injectors x duty cycle) This Size Selection Guide is intended to help in determining what size injector to use in your application. * Brake Specific Fuel Consumption: This is the amount of fuel consumed (in lbs. per hour) for each horsepower made. This should be .45 to .50 for naturally aspirated engines Supercharged engines should be between .55 to .60 Turbocharged engines.60 to .65 Rotary engines, estimate BSFC to be 0.6 to 0.7 For engines running methanol, double the appropriate gasoline BSFC (e.g. a rotary engine running methanol has a BSFC between 1.2 and 1.4) ** Maximum Injector Duty Cycle should be around 80% max for safe operation. This allows for some future horsepower increases. 32s are too large, even with tuning. Matthew |
