fuel economy

Just trying to gauge what kinda gas mileage I might see with my combo. 302, AFR 185's, TFS stage1 cam, Victor jr intake, single turbo, E85 blowthrough carb, 5sp, 3.55's. 92 coupe with full interior.

What engine management are you using?

Custom built (horsepower innovations)Holley 950 HP carb. MSD 6530 programmable ignition. I'm trying to size a fuel cell, there are enough E85 stations within a 100 mile radius, a 10 gallon will fit the best, and still provide me with enough range. I'm hoping for 15mpg highway.

I think 15-16 may be your high end for highway mileage. Really depends on your driving style. If you can Lean it out under light load highway driving and still keep drivability, you'll get pretty good mileage out of it.

blow thru carb on e85 your mileage is going to be awful. Most I've been around have had stalled autos, but they're all usually pretty bad.

MPG can't be super important if you want a setup like this.


If it's not dialed in perfect it may even be single digit mpg.
