simple, for those making 750-ish on E85.
what size injectors and duty cycle you're running? go

What do you want to spend? You would need 80-100 lbs or so. I have FIClinic 1100's which at our 58-60psi base (4 bar) are pretty much like the other 127lb injectors. Mine work perfect and at that power would only be ~70% DC without checking my logs.

thanks, more focused on the ideal injectors, than budget. Don't want to do it again, currently maxing out my ID850s, which I thought would of made it.

Really? What AFR are you targeting? Pure E85 or is it a lower concentration like e70, etc. I guess knowing the dyno you are on helps also if it's a stingy one.

haven't gathered enough data yet, stopped dyno tuning at 91% IDC @6000rpm , at 10.9afr, on the street, saw 115% @7200RPM, yea I can lean it out to 11.7ish, but still won't be in a comfy range and still looking for more power. this is on pure E85, so Just trying to get an idea where everyone else is.

Right, my number above were based on something less pure like E70-75 which will stretch the injector.

Are you running a full return style (boost referenced) fuel system and whats is your base fuel psi?

I am running bosch 127's in my car.

I ran ID1000 cc injectors at that power level with e85 and an a&a secondary fuel system. I was in the mid to low 80% range at peak IDC

FourG63 97GST

yes, return style 1:1, base pressure 58psi

I was going to suggest Bosch 127s or 160s. Be glad to help if you want to shoot me a PM.

If your fuel pump can flow enough at higher pressures raise base pressure to 70ish. It'll make a difference. Unless you just wanna buy bigger injectors. Idk my power level exactly but I'm trapping 125+in the 1/8 and my injectors are 105lb at 65 base psi and running e85. I'm running the Deatschwerks 90lb LS3 injectors and I'm at 95% duty cycle!

Have you watched fuel psi during a pull?
