Injectors needed for E85.... Size matters
Need some opinions guys. Please post your injector size if you are running E85. I need a setup in my Evo 9 that can switch between Cal grade 91 and E85. I travel commonly between Cali and Vegas and E85 is not available in the 4 1/2 to 5hr drive. My setup is vast but for running 91 oct I have been told that 2150cc injectors will have an issue with idle. The power I'm looking to hit is 600whp "550whp MINIMUM". My mods list is at the bottom but I also have a new 450lph fuel pump I need to install. Let me know what you think. I'm thinking either 1300cc or 1450cc but is that enough???

https://www.evolutionm.net/forums/sh...3#post10533943 if u end up getting 1450, I have no idea on what you will need. I'm sure a call to an EVO shop would get the answer, evasive motorsports, road race engineering etc

ask your tuner how good he is at scaling injectors. if he's good you can go as big as you want and the good tune will idle just fine after the car warms up. if your tuner isnt the best, i would suggest 1450's-1650's
im on fic 1450's making 430 uncorrected hp on e85 with a single walbro

I have this exact same question. I've spoken to one tuner and they said that the FIC blue max 1450 and 1680 we no good. Another tuner told me ID2000 for sure. I want to run e85 and am looking to get to 600HP. ID2000 are just SO expensive for fuel injectors. Oh well, gotta pay to play I guess.

Be advised that regardless of what you do, how your car runs is reflective of the time and attention a qualified individual is willing to invest in developing a proper, comprehensive tune.

I agree with this. It sounded to me like the tuner was unable to tune that injector as opposed to it not being a good injector. I was also told by someone else though that anjectors larger than 1250 are troublesome on pump gas. do you have the high impedence or low impedence?
I have FIC Bluemax 1450s running nicely both on pump gasoline and E85 with the BIG Crane cams. This simple fact indicates whatever was 'no good' had little to do with the injectors.

The FIC 1450s are Low-Z, peak and hold type.
I'm fine with the Bosch EV14 saturated type Hi-Z injectors, but there is a bit of a sizing void where the 600whp w/E85 requirements are concerned. Speaking personally, I'd go with a high-pressure fuel supply and 1100s as opposed to spending for a set of comfortably oversized 2000cc/min units with a conventional fuel setup.
