120 lbs (1260cc)
160 lbs (1680cc)
200 lbs (2100cc)
For high impedance applications.
Uses EV6 / USCAR type connector.
Measuring only 1.480" o ring to o ring in height.
How to choose the correct size EFI injector.
1. Take your target peak horsepower and multiply by
* 0.5 for naturally aspirated
* 0.6 for supercharged
* 0.625 for turbocharged
2. Take that figure and divide by the number of injectors being used.
3. Divide by .9 (for 90% duty cycle).
This will give you the lb./hr you will need for each injector.
Example: 800 horsepower, supercharged V8 with 8 injectors.
( 800 x .6 = 480 ), ( 480 / 8 = 60 ), ( 60 / .9 = 66.666 )
This application would require 66.666 pound per hr Fuel injectors.
If the formula give you a number that is not available then the general rule is to move up to the next larger size.
NOTE: This formula is for 98 octane fuel.
