why are people, specifically in the hot rod world swapping to e85 gas. I see the slight cost difference but the energy released is not as much. so i see it as you need more fuel to do what gas does.. just wanna know why. i do get the lines ( gas is more corrosive for regular fuel lines ) and such and a few things have to be changed and adjusted .. I just don't see why swapping to it when you need more fuel to do what gas does ..

14.7:1-15:1 static compression and 12.5:1 dynamic compression,
is generally considered about ideal for ethanol powered e85 engines
if you run e85 in an engine with low enough compression that the engine can be run on pump gas you'll see very little benefit from e85 fuel use.
ethanol or E85 is very corrosive to many plastics, synthetics and even aluminum over time.
boost the mechanical compression to about 15:1 and get the cam timing
to produce about a 12.5:1 dynamic compression and the engines characteristics and power potential increases remarkably
if you use a low compression engine ethanol fuel provides less mileage per gallon and less power,
but ethanol and METHANOL both potentially can provide a significant boost in power if the engines built with a high enough compression ratio to take full advantage of the higher octane,or knock resistance the alcohol provides, yes it will require about 25%-30% more fuel , but the power potential is certainly available if the engines built with high mechanical compression, gains of 5%-10% or more in peak torque and horse power are rather easily made if the proper components and compression ratio are used to take advantage of the alcohols different burn characteristics and potential.
the problem is that most engines are not exclusively designed to run ethanol.
any engine designed to use both race octane gas and alcohol interchangeably is not designed to maximize the alcohol characteristics,

heres a good example of an engine designed to run both e85 and race octane gas, in my opinion the potential corrosion issues make the use of the slightly cheaper e85 , just not worth the hassle.
