E85 ?

My DD race car has been on e85 for the last few summers. It let me add 7* of timing at the peak im my junk.
But it is a S/C 3800, so I don't run any impressive times compared to the real race cars around here. You may not have the same gains.
P.S. If you're NA, e85 won't net you much unless you built the motor for it or race gas.

A 55 gallon drum of 110 leaded from Sunoco is $525.08. That's about $9.55/gallon. Where are you getting $6.99 from? Are you buying swimming pools of it to get a bulk discount?
104 unleaded is even more.
E85 is a bargain even if you burn twice as much

Because nothing out if a pump is pure. Gas stations don't close down after a fuel truck refills like they should. Who knows how much water and sediment is sitting at the bottom of those tanks. If I'm going to run something through a 10k dollar motor, its gonna come out of a sealed drum
After a few years on Corn with my own car, as well as making the switch for a few friends, I can truly say anyone running forced induction is a fool to not consider Ethanol.
Using me as an example, my setup's par is 310whp and 325 lb-ft out of the box. My car, on an INCREDIBLY mild E85 tune, with low boost and timing, produces roughly 100 WHP/TQ more. Meanwhile, I lost a pretty negligible amount for mileage. Pump I see around 30 HWY, 25 City. On Ethanol, 25/17-20 (because I suck at staying out of the throttle some days.)
Daily driven too, fuckers. No excuses!

E85 is a fantastic choice for a Forced induction engine. It is a good choice for a NA engine too, although the gains will not be as big compared to FI.
You will use about 30-35% more fuel with E85, so you will most likely need a larger pump and injectors.
When we had my car on the dyno it made 547whp @30psi on 93 octane on very little timing. we put E85 in it and only tuned the boost up 2psi to 32 (and added only 2 or 3 degrees of timing) and the car made 639whp.
92whp is a pretty damn big jump considering the car was about maxed out on 93 and nowhere near the limit on E85 (could add a good amount of timing and turn the boost up 6-8 more psi)
To me it's a no-brainer
