What numbers are you guys getting mpg wise in the city and highway driving? Please include driving conditions, i.e. cruising around hitting light boost doing a pull every so often, or just full boost at every stoplight.

My setup is almost done and will be back on the road shortly. this will be my 1st time trying out E85.

Car: 93 Integra RS
Weight: 2400lbs without driver 1/2 tank of gas
2584lbs with driver 1/2 tank of gas
motor: 11:1 compression b16 turbo 60 trim, ramhorn, b16 trans 4.7FD
type of Ethanol: E85,E70 E98 etc.
currently running E70 (due to winter time here in NC right around the corner)
If u want post up AFR's while cruising.

I have one question how LEAN can you run your AFR's with E85 at cruising speeds before it starts to get too hot? I would imagine tuning the car super lean would offset the loss in gas mileage people claim with E85 over 93 octane.

 

At light cruising you can tune a car on 91/93 fairly lean as well, so really there's no offsetting the loss.

 

This has 3 pages worth of mileage info if you want to go through it and add it to this.
