Yeah, at IMSCC all the e85 guys were in the low to mid teens. The Evo guy was able to get 21mpg tho.

Quoting prove_it:
Really? I lean burn the crap out of my E85 and get about 14-16mpg.... at 85mph.
Otherwise, I average about 12-22 mixed pending on how heavy my foot is. At WOT it drops to around 1-2.....(just guessing)
The other things playing in my favor for better mpg are the evo III 5th gear, I spent a ton of time with the timing maps in the cruising cells. Its amazing how much more torque you can get out of these engines when you get those worked out. I'm not sure what else would create the difference. I also have a twin scroll manifold that might net me a little more efficiency. I would make sure everything in your driveline is rolling smoothly/no drag. I had a caliper that was sticky and I was struggling to get 20mpg highway.

You missed the part about going 85.... at 75 it goes up. I'm proud of those numbers, again at 85 in a brick on ethanol with 235/45R17s.
Yes, all wheel bearings new, driveline rebuilt. The rear diff needs rebuilding, and the axles are 22yrs old.

For fuel economy I am sure it has benefits but you would need to be drafting really close to get the full benefit and doing it long term is really tempting fate in my opinion. I never concentrate only on the brake lights of the car in front, I'm constantly checking two or three cars ahead and you can't do that tucked in behind the rear bumper of a semi.

12mpg on E85 mixed driving ie. spirited boosting, little highway and a lot of city driving. I drove it to MO (700 mile round trip) last month and I did about 320 miles to the tank. That's about 19mpg....pretty shitty IMO. This was on pump gas though with an untouched tune. Speeds averaged 75-85mph.
In my old Talon I got much better gas mileage but I ran that car in forced open loop all the time and my highway tune (15-16AFR) was dramatically leaned out for fuel economy.
