finishing getting all my stuff together for spring and have heard so many mix reviews about injector size when it comes to running e85

setup will be a simple N/A C6z ls7 . Trickflow heads. Lingenfelter GT21 cam. Tony mamo MSD intake. Full catless exhaust.

Car will be running pump 93 and e85

Had heard many differnt opnions or watched other builds and the injector choices are all over. so was looking for some more educated thoughts for my step up

All of the ID “X” line are now engineered for ethanol use, from what I’ve read. It appears the smallest injector they now offer is the 1050X, which should be plenty of injector for you on E85. The IDs are expensive but worth every penny, imho.

I’d do the 1050X’s

found a deal on id1050x for 850... thinking off pulling the plug brand new never used

IMO its not worth the $$$ on a N/A setup. Might gain 10 hp

chrisc751

yeah 15whp is the average ive seen. looking to get the most out of the n/a setup that i can and e85 pump is local to me. just dont wanna buy injectors and then have to repurchase them down the line if i wanna revist e85 again. what would you say the lsa injectors are are safe for power wise on pump?

Tech

ID1050X will be the last fuel injector you'll ever buy if you stay naturally aspirated and on either pump gas or E85.

Turbo2L

15rwhp and probably 20rwtq throughout the powerband and the ability to run 12.5:1+ compression on pump gas and double the horsepower and torque gains. Seems like a no brainer.

I'm at 12.4:1 and wish I would've gone 13.8:1. The power delivery on the car is much more enjoyable with higher compression and E85 IMHO.

Would you lose the ability to flex back to pump 93 with a CR of 13.8:1 ?

No. You would have to tune very conservatively on pump gas but you can do it.

IMO, it's worth it. The car behaves so much better on E85 compared to pump gas. The exhaust smell isn't as bad, runs cooler, cleaner, less chance for detonation, pick up noticeable power throughout the whole rev range, cheaper. The cons are very few; more fillups, less pumps available, always wanting to smash the gas.

FWIW, I run ID1000s, N/A. I have plenty of overhead for anything I plan to do, within reason. For instance, adding fuel through my injectors for a DRY shot of nitrous.

chrisc751

how are the iID1000s driveability wise and how are they taking the e85?

schpenxel

ID1000's are totally fine idle wise on 93 or E85.

Haven't had any issues with mine on E85. They basically sat with E85 in them for half the winter and have been fine. I might send them back to ID at some point and have them check them out but so far so good.

1050X's are a better option though if you know you're going to be running E85

Tech

I have 1050s and I couldn't tell a difference in idle quality from my stock injectors to 850s and now these 1050s.

as long as you aren't running mtbe fuels like q16 the non x line is fine. personally on my ls2 I went the cheaper route and got some siemens deka 80lb. makes right at 500 on motor, idle and drivability is perfect. been on e85 for two years.

ran the id10000 in my supercharged m3 on e85 and it sat all the time, no issues until my supercharger seal let go and dumped the supercharger oil into motor blowing it up. so now im putting a ls turbo into it lol

Turbo2L

The turbo four cylinder world has hammered ID injectors with e98 for the past 10 years and they haven't flinched. I wouldn't expect to have any issues with ID injectors on E fuels at all.
