Because too much power, is never enough. "Jet" brand centifugal at approx 8 psi, E85 and( 2) 2bbl, GM tbi's. Can the factory injectors be up-graded with aftermarket,Accel, Venom,Bosch etc ? Re-flashed GM ,ecm with (4) injector drivers. Suggestions ? Thanks, roverman.

Dear Jim N., I don' t suppose your suggestion has anything to do with your recent stock purchase,ie. "Fast" ? 1,800 cfm....Really ? The idea of using as much oem. equipment, as practical, so as not to sell a kidney, appeals to me. It's jus a lil' hemi, and a smaller budget. lol, roverman.

I've just been informed, I'll need approx 140 lbs/hr, X (4), on E85, 70% duty cycle @ 600 hp. Will any injector that huge ,even retrofit into GM tbi ?? Help ! roverman.

Hey Art,

Talk to a good injector rebuilding shop. Motor Man and R/C come to mind first.
They should be able to rebuild and recalibrate your injectors for you.
Or you can just leave the injectors out for the same effect!

Cheers

Fred and clan, "Xtreme EFI" says GM tbi's not compatible with E85/alcohols. Accel "port" injectors are, with up to 160lbs/hr,(low impedence).Where get/make tb/tbi's to take port injectors ? I like concept of injectors"under" the slide plate/butterfly.How bout' oem. tb's mounted vertically ? Thanks, roverman.

Just a "little" more, please ? Evidently NOT. Why ? It's looking like Megasquirt III might be better controller, ie. cop.,E85 and supercharged ? Thanks, in advance, roverman.
