How much horsepower are you making? Do you think you need 50lb injectors? I've got built 540s with vortec chargers running 43 lb injectors that make 800 hp. And I'm good up to 950 with them.

Curious how you are making that power with a 43 lb injector.

43x8 = 344lb per hr x 2 IF at .50 bsfc =688 hp mwxed right at 100% duty cycle, if turned fuel press up and forced injectors to flow 50lbs your still only talking 800 hp and thats w pw maxed to 100% which is a nono, im interested too as math doesnt work out!

That's what I was thinking. I'm running 42 lb injectors on a small block.
