#68846, "What is the formula (Fuel injectors)"


          

I need to know what size injectors to run. I read the formula for it (comp. ratio/boost= cc injec. or something) somewhere on this site a long time ago but now I cant find it. That was also before I cracked the ring lands on 2 of my pistons. I just need to know because I am having custom pistons made right now by atomic speedware and I want to make sure there is plenty of fuel. Any info will be useful to me. Thanks.

http://www.mindspring.com/~steveflyer/fuel_injector_size.htm

this link is an injectior sizing calculator.
make sure and put .55 for the BSFC and 80 for the duty cycle

remember that with a rising rate fuel pressure regulator you can use smaller injectors because the flow rate increases with fuel pressure.
