80lb/hr minimum, two 340 L/hr would do plenty. you would also likely be fine with a 255 in tank and a 340 external. I would honestly recommend a 90# or larger injector for breathing room.

I'm running 90# injectors (equivalent at my pressure) and I'm at 71% duty cycle on my setup making 650rwhp and 680rwtq, somewhere around 75~80LB/min airflow up to 6400 rpm

What type of fuel, how much boost pressure,fuel psi, and estimate flywheel hp? Probally 1000cc
