Does anyone know where I can find some good info on proper fuel injector sizing? More specifically, how much boost can be run on a 450 injector. I realize that there are many other factors invloved, but that kind of info seems to be hard to come by.. Any help would be appreciated!

Thanks

 

I think RC engineering has a couple good calculators for HP injector requirements.
As for 450s they are good for about ~280-300 flywheel horsepower so about 250whp but thats at about 43psi fuel pressure now you can raise the fuel pressure and effectivly get more out of the injectors but as for boost your probably looking at around 10-12psi max for those
