Using an online calculator, the 42# injectors are good for close to 450 hp max at 80% injector pulse width, any higher than that the injector isn't as efficient.

According to a calculator that won't let me get the link to post, max recommended HP for the 24 and 30# injectors at 80% duty cycle is:

24# = 256 hp
30# = 320 hp

Oh, and I believe that is flywheel hp.

ive herd the stock rails can support up to 450hp,,the math on the on stock 19lbs is 243 hp at 80% duty cycle 30 pounders are used for a little more then 350hp...as for the stock fuel pump its a 110lph rated at 38 psi,,used for 250hp engines

cant even attempt to answer this question unless we establish whether we are talking forced induction, nitrous or n/a. Any FI car will require more fuel to make the same amount of power as a n/a car.

I need details.

 

[TBapp3]

I know he is N/A thats for sure!

They are 19psi and they are done around 285ish the pump is done around 300hp. The Mach fuel pump is maxed out from the factory all the way up top.
