RaceTronix 160lb injectors

I have 120's from Eric , 75% duty cycle @ 30 psi boost on E85 , base fuel pressure @ 50psi . Racetronix 680lph double pumper , -8 feed & -6 return lines .
You probably will need more pump than the one you have now on E85 .
Is your Fast system a sportsman or standard XFI ? Because the sportsman will not support low Z injectors without a resistor box .

The resistor box works great. 120's from Eric, couldn't beat his price. He now has 160's listed on his site.
 
160's and reg pump gas gets pretty dam low on teh PW at idle and can have idle/tip in, etc issues. With E fuels they work great. The 120's are the biggest with reg pump gas and still have good driveability IME
 
I got some 160s from a friend and I think they are Bosch if I remember correctly....they are gray and yellow...
can be found all over the internet , so no Racetronix isn't the only option...

Whats high psi?
I think I have those..
A couple sets were in outlaw 10.5 cars, operating at 70psi base pressure, on methanol. I put them on the bench, and when I turned the pump on, I got a face full of flow fluid.
AIRC, I could twist the shell halves, by hand.
Once 1 in a set fails, we break all of them, w/ a hammer.
The Racetronix injs are not the old design, LP units.
