Answers to the questions on running E85:
Car - 1972 Mustang Mach 1, 351c (cleveland) stroked to 408 with alloy heads and roller cam, and now fuel injected. 500hp rear wheels, 490 ft lbs torque peak. Best 11.64 @ 115.5 mph in the 1/4 mile.
Hoses, etc. - It is NOT true that E85 is "harder" on hoses than gas, or if it is, its such a slight amount that I have yet to notice it. What it will do - clean out your gas tank and/or fuel lines. I noticed that on the first tank or two it really cleared out that gas varnish that gets deposited everywhere. It wasn't until my 2nd tank that it ran well, and I did, because it was easy, remove my fuel filter and clean it (reusable filter) between tank 1 and tank 2. Really wasn't very dirty. It WILL clean your plugs, your exhaust, etc. because it runs THAT clean!
