How do you calculate injector flow rate?
New Flow Rate:
- The formula to find the new FUEL FLOW rate after a fuel pressure change:
- Example 1: A 240 CC injector tested at 43.5 PSI is run at 50 PSI.
- So, the resultant change in pressure would yield the following: 240 cc/Min X 1.0721 = 257 cc/Min. 22.86 Lb/Hr X 1.0721 = 24.51 Lb/Hr. 36.58 Hp X 1.0721 = 39.22 Hp.
How do you measure a fuel injector?
Fuel Injectors are sized by their flow rate. Flow rate is a measurement of how much fuel can be delivered over time. It is listed in pounds per hour (lbs./hr.) or cubic centimeters per minute (cc/min.). The right size injector can supply enough fuel under full load conditions at an 80% duty cycle.
What is the flow rate of a fuel injector?
Most injectors are flow rated at 43.5 psi. (Motorcraft rates their injectors at 39.15 psi.) If you are running a different pressure, your actual flow rate will be different than the advertised rate. For example, what happens to the output of a 24 lbs./hr.
How much power can 1000cc injectors make?
The 1000cc Injectors can support 650+whp.
How do you adjust the flow rate of a fuel injector?
Hold the throttle steady at 3,000 rpm and adjust the “injector size” setting higher or lower until you reach the same air/fuel ratio that you wrote down in step 3 above. Adjust the injector size lower to richen/increase fuel. Adjust the injector size higher to lean/decrease fuel.
How do you measure fuel pump output?
An often overlooked, final test is pump volume. The simplest volume test involves opening the fuel supply line at the injector rail, then measuring fuel volume during a timed, power-on fuel pump test. This involves pumping gasoline into an open container at a high rate, which poses obvious safety risks.
How much HP can 1000cc injectors handle?
How much HP can 550cc injectors handle?
Typically, 550cc injectors are good for 350whp. You can get 350whp from 15psi from a GT30R or 10-12psi using a GT35R. I always make sure i run larger injectors than i need.
How do you check cc injectors?
thanks a lot guys! you need to make a rig to apply +12V across the pins on the injector, and also have a fuel feed with pressure. once you apply the 12V, you measure how much fuel comes out in 1 minute. the volume that comes out of the injector cc’s is the cc/min of the injector @ the psi of the fuel pressure.
How to calculate the flow rate of a fuel injector?
Use the flow rate (Bar) listed on this site as the “old” pressure, and the pressure you would like to know as the “New” pressure. To convert Bar to psi, multiply the Bar number by 14.7 and this is the number you would use. Enter the flow rate on this page as the “Old Flow Rate” and press “Calculate”.
Why do I need a higher flow injector?
Through tuning or a pulley upgrade on any engine factory-equipped with a turbo- or super-charger, or installing a larger turbo- or more powerful super-charger, higher flow fuel injectors should be considered as part of this upgrade. More air to the engine necessitates an increase in fuel to maintain desired Air/fuel ratio (AFR).
How big is the duty cycle fuel injector?
Duty Cycle(? 80%85%90%95%100% Injector Size Required: Fuel Type cc/min lb/hr Gasoline E85 * Consult your engine builder for more accurate estimates.
What should my fuel injector pressure be for 4 wheel drive?
Because of the variable percentages lost with; front and rear, 4-wheel or all-wheel drive, we can make slight adjustments when needed. Also note that the our flow-rate calculator assumes a base fuel pressure of 3 Bar (43.5 psi) and a maximum injector duty cycle (IDC) of 80%.
