Default How much power is my fuel system capable of?

I am going to wait a little before I build a big fuel system so I am going to run what I have now. How much power with 42lb svo w/ a 255 pump support? My guess would be mid 500s on 5 or 6lbs. Its feeding a 8.6:1 370 with ported heads and a custom cam, kytp kit.

If you are trying to get 550rwhp on a FI car, I would go bigger than 42lb injectors.

i am going for close to 800rwhp, I wil order 75lbers when I do that. I just wanna know what a 42lb (48lb on our car) is good for when performing against low boost.

Never mind I used the fuel injector calculator at rceng.com looks like 550 will be the limit of the injectors at .80 duty cycle.

Remember all the calculators are in crank/flywheel horsepower.
