JOE BLO SPEED SHOP Injectors All of our kits are designed to fit the LS3 / LS7 type Injector. We can supply these EFI injectors in the following sizes. 39 lbs (409.5cc) 50 lbs (525cc) 65 lbs (682.5cc) 85 lbs (892.5cc) 100 lbs (1050cc) all rated @ 58 PSI 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. |
