the passages are a lot bigger for alcohol than E

its been done but not ideal

 

Personally I feel the main well, booster channels and boosters are too big to make a methanol carb into an E85 carb. Or at least a good working E85 carb.

 

Thank you Sir! Nix that idea... lol

 

Alcohol is alcohol. E85 is ethanol and gas mixed. We converted my son's car to e85 last year.it was a pain in the ass. The problem with carbed e85 setups is evaporation. The e85 sits in the inground tanks and the ethanol starts evaporating. Then it sits in the car for a few weeks and evaporates even more. The ethanol always evaporates faster than the gas. So now you are tuned for e85 but end up with e60 and now the car is pig rich. Also take into consideration that e85 is only the max. The store can legally sell e25 as e85.

Obviously fuel injected cars are easier to work with if they are self learning.
Another thing to consider is fuel line sizes and fuel pump compatibility.

 

Lots of incorrect info here.

 

Thanks, we might as well just run methanol cause we always have it from the sprint car.

 

Lots of incorrect info here.

i have a flex fuel sensor in my car and can tell definitively that is not the case.


my biggest complaint about carburated e85 is that when you shut the engine off hot it boils the fuel out of the carb when you shut it off and the carb heat soaks. so its flooded when you restart it.

 

Good thread. I too wondered what the difference was.

Learn something new every day.

 

Shut off the fuel pump before you shut the engine off and let it empty out the carb first. No more boil out or pig rich.

 

Op, alcohol is for drinking. Gasoline is for racing. :smt097

 

^^^^^This

 

Some e85 carb mods at this link. Just keep in mind that it's somewhat dated info but some of the basic stuff is probably applicable today!

Thanks, now if I can talk this high roller outta this carb we will be set!

 

All I can tell you about the carbs is eric from e-85 told me it was better to convert a gas carb then a alky carb, same for the guys at cornfedracing.com another good source of info is raceone-85.com good carb setup info there as well. plus they sell kits to modify the carb for e-85.

E25 seems really low to me, Im in Indiana and most use a hydrometry to determine its proof at the pump. I think some have gone as low as E70s ( ish ) but I have never been told anything below that.

 

Is it evaporating or taking on moisture?... open vents and higher humidity will act upon eth and meth, stuff is like a sponge.

I get my e85 by the drum and keep it sealed well. Costs a little more (still less than half the cost of race "gas") but it's consistent

 

Well......you drink one, and put the other one on a car or boat.
