Note: This app does not contain any advertising.This fuel injector calculation app consist of four parts.1. Based on injector size the calculator will calculate power output in HP or KW.Calculate the estimated horsepower and KW a fuel injector of a specific size can support to the crankshaft and wheels based on whether the engine use normal gasoline, E85, E98 and or Methanol and whether the engine is normal aspirated, super charged or turbo charged.The calculator also allows you to calculate the above perimeters based on a change in the fuel pressure.Calculation output will provide horsepower and KW per injector, Total HP or KW, Injector flow in lb./hr. and cc/min total fuel flow in lb./hr. and cc/min, and Flow in gallons/hr. and litters/hr.2. Calculate injector size based on power demand.Calculate the estimated injector size required based on crankshaft horsepower or KW input. This calculation is based on whether the engine use normal gasoline, E85, E98 and or Methanol and whether the engine is normal aspirated, super charged or turbo charged.Calculation output will provide injector size in lb. /hr. and cc/min, Total fuel flow in lb. /hr. and cc/min, and Total flow in gallons/hr. and litters/hr.3. Calculate new injector size when fuel pressure changeThis calculator will calculate the new fuel flow for a specific injector when the fuel pressure change.4.Convert lb/hr to cc/min to g/s plus other helpful conversionsThis is a multi function conversion calculator that allows you to convert lb. /hr. to cc/min and grams/s or cc/min to lb. /her and g/s or grams/s to lb. /hr. and cc/min.It also has other helpful conversions such as Lambda to AFR to Lambda, Injector Duty Cycle, HP to KW to HP, MPH to KMH to MPH and more.Note to end user:The calculations is there to guide the user to a starting point and not as an absolute recommendation. The user must always confirm that what has been calculated will work with his or her application.
