E85 Conversion adapters...

[31_bandits]

to convert an engine to E85 means computer changes and internal engine changes as well.

pumps and lines and different things have to be made resistant to E85... my understanding is that it cannot be done to a 6 liter (an E85 conversion).

There are a few other things about E85 to consider; it is electrically conductive which could present a hazard in a non compliant fuel system.

It's BTU yield is less than gasoline so any savings in purchase price is usually negated by lower mileage. It's also hygroscopic meaning it attracts water, again this is a problem for non E85 flex fuel vehicles.

The higher octane rating while attractive to prevent detonation (engine knock) won't be realized without a change in the compression ratio (major engine modification) or timing advance (minor output increase).

I'm not knocking E85, our Town & Country is equipped for it and I just finished a 1750 hp motor design for an ethanol plant in Kansas last week.

Depending on who's math you agree with, Ethanol production currently uses more energy than it produces and could not exist without subsidies. Sugar Beets actually provide more yield but are not in widespread production.

I'm all for developing alternate fuels, but heavy reliance on the food supply for fuel production has high risk. It reminds me of being broke in college, do you want to eat or drive this week?
