Default Low impedance converter box & 72# injectors.....

I consider this another option for fuel, would this setup work well with a stock PCM setup?

I think this would be plenty of fuel with a 420L inline or twin 340's in the tank?

Anyone running something like this?

y2khawk and speed inc. have made them before for the stock computer.

at our stock fuel pressure (4 bar)
42's are good for 700 flywheel
57's or 60's for 900
72's for 1150 flywheel
83's for 1300 horsepower.

for your trans/converter/rear i would multiply all these by .75 to give you a rear wheel capability.

many of us, including myself run a rising rate regulator at 1psi per pound boost.... which can get you even more flow.. but i wouldnt go over 80psi or so fuel pressure for any reason.. time to move up to a larger injector then.

the 410 pump is right at as much as you want to use the stock lines for.
