68846, What is the formula (Fuel injectors)
Posted by spoolinfoo, Apr-12-04 08:16 AM
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.

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.
