Gasoline cars get 6x ID2000s. We're building one that will be running E85 that will be running two sets of injectors, likely 1000s and 2000s. Fuel supply has not be a problem thus far.

What is the fuel pressure you're running after boost? Maybe running a weldon in line makes it Ok to run higher pressure.
Hmm just noticed you said mechanical. I want to run one, but think it might be too complicated at the present time.
I stand corrected, the pump we run is not mechanical. Electrically driven.
I talked to John Bray, our engine builder and mastermind of all the race cars here. He generally runs 43.5psi if he doesn't have to run any higher (if he has enough injector). With the Weldon pump on a short run to the rails, and with the rails returning to the surge tank, he could get away with a single 044 tank pump feeding a good sized surge tank. We run 2-3 gal surge tanks like I said, and he said a single 044 would not let that tank run close to dry over a standing mile run with the main pump returning back. Something like Bonneville would be a different story, but two 044s would be sufficient then.
