Re: better gas mileage with acetone?
That's kind of what I was thinking. I wouldn't do it for an exclusive daily driver, but just for a toy I think it would be fun. You could build a low 11 or even 10 second Honda that runs those times in street trim.... hmmm...
Are you still in Denver or somewhere like that?

Re: better gas mileage with acetone?
i went to advance auto parts and in the paint isle they have 100% acetone 32oz for like 5 bux. i then went to 711 and bought one of those 2oz bottles of 5 hour energy, chugged it, then after i was done gagging i poured the acetone into the bottle. i filled up about 13 gallons and dumped 4oz of acetone in my 01 chevy extreme with 4.3L m/t. i'm getting ready to drive to greenville NC for the Slamsession car show. i will let everyone know if i have to get towed home.

Re: better gas mileage with acetone?
I'm just gonna measure the gallons I used and keep track of the miles with the trip meter. It might be too late for you to get any before mileage since you're already using the acetone. I've been waiting to run down my tank so I can try it. Next tank will be "before" mileage. Then I'll probably get new plugs and change the air filter on the next tank. So I'm at least three and a half tanks away from seeing if the acetone does anything.

It's easy to do, all you need is correctly sized injectors, seals that you know are ethanol safe, and you're set. However, an E85 tune won't work on pump gas, so you're stuck with E85.
All my engine management development this spring and summer with our 13.5:1 comp setup will be with E85, you can't beat 105 octane pump gas.

I believe there's a bit more to it than sizing injectors and choosing seals. E85 corrodes aluminum, so the injectors, pump, fuel rail, etc would need to be anodized or specified for E85. It's definitely doable but needs to be well thought out.

Most all of the Al parts should already be anodized or otherwise protected, there aren't many fuel system parts that should be affected.
