E85 in my area is 2.85 and 116 is 16.00 per gallon. I think the benefits of e85 are awesome. My local dyno shop has found that around e60 full ethanol power timing can be used with the anything more helping with intercooling and spool. I mix down with pump 92 and end up close to 8 gallons when 5 gallons of e85 is used
Well, I doubt switching to gasoline is suddenly going to convert your 1500 hp car into an economy car. You might get a couple mpg.
When you are getting 10 mpg, is 12-13 really going to make a difference?
Since you have to travel a bit to buy C16, why not get a drum or two and travel a bit further and get E85?
My buddies here in Portland do. We only have one source at present. Last time it was $2.19.
I've never tried to calculate mileage. All I know is it's better than my rat motor, and the car is way faster.

So your probably getting around 10 mpg without racing it? 15 gallon tank with 1/4 tank left would be around 11 gallons used. You are probably using around a gallon a pass at the track. That would put you around 5-6 gallons for the 60 mile trip. That doesn't seem too bad for a car with power to need a chute with 3.90's and t400.
Something is wrong with the setup as a whole getting that kind of mileage IMO. I was right around 25mpg on E85 (closer to e70 here local) cruising 55. 2950lbs 3.10 gear 29" tire.
Also leaving E85 in the system for a few weeks shouldn't cost you a set of injectors? I leave mine in the tank all year and all winter... Using racetronix 160's. What type of filter are you running? pre/post pump?
I'd suggest running e50-e60 as mentioned. It should eliminate any fuel tar/goo/clogging issues with the higher gasoline content, improve mileage, and lower the fuel system requirements for big power. Then use water/meth on top for added insurance. Cheapest and biggest bang for the buck around 1000hp IMO.
All that said, 1500hp is pretty serious. I'd consider having 2 seperate fuel cells and running it on C16 when at the track pushing it. Then cruise around town on the E50.

Right... no one said it couldn't be done. But if I'm running a big dollar 1500hp setup, running a fuel meant for the task that is strictly monitored is a better idea in general. "E85" and whats blended with it changes region to region and all throughout the season. With C16 you know you are getting the same fuel/octane every time. There is absolutely no doubt c16 is a better "race" fuel and capable of more power with a higher octane. But you are paying quite a bit for that assurity. So IMO not worth it on the low buck stuff, but well worth it on the big $ builds.

Verdad Gallardo This is one of the guys I'm referring to: That was quite a few years ago and since then he's done a TT 632 that makes enough to go mid to low 4's it was on E98 though. We go buy it (E98) by the drum at Davis oil company.
I lost a set of injectors from e85 which is why I'm contemplating c16, the big drums require a pressurizing system to keep the fuel fresh, I'm not going that crazy. I'll have to buy it in 5 gallon drums if I go that route
I always add this to my pump E-85: http://lucasoil.com/products/fuel-tr...th-stabilizers
In my experience it did little to nothing. What did help was running a gallon of straight toluene through the system every 6 months or so. (also kicks up octane a ton so it's a win/win) I had the tar build up on the injectors, and that seemed to do away with most it... the lucas stuff didn't do a thing to it in my specific case. Lots of folks don't have issues at all.

Ever look at the MSDS on that stuff? It looks like it's just a small amount petroleum distillate (5-10%) and (60-100%) naphtha. Basically a little mineral spirits and lantern fuel. Super cheap stuff anyway... I don't see how it "stabilizes" anything with those ingredients.

That's how it was in my area as well. Very nice alternative...until the only local station to me quit carrying it a few weeks ago. Now the closet one to me is probably 45min to an hr away. At least I have the flex fuel sensor operational so I can run on pump around town. I'll just keep some on hand at my house for when I have a race coming up.
Launching!

"There is absolutely no doubt c16 is a better "race" fuel and capable of more power with a higher octane."
this was what I always wondered. I don't really care about the cost personally and would run either depending on which one made more power.
seems like E85 has its own issues and is cheaper but then I need 30% more fuel system which is big $$ in a c6 platform, or can pay more for C16 and my current fuel system is fine (saves money) but have to pay a ton more per gallon but then also no potential fuel moisture issues.
