[AMC-List] E - 85 'The Cool Fuel'

["Brien Tourville" <hh7x@xxxxxxxxxxx>]

E85 may have a performance advantage in forced induction engines.  
Ethanol has ~ 2.6 times the latent heat of vaporization (Btu/gallon), 
and
the heating value of ethanol is only ~.6 of the heating value of 
gasolene
(Btu/gallon).  This means you could expect the intake air to be
significantly cooler when using E85; possibly cool enough to 
eliminate the
need for an intercooler.  Westech Performance Group measured a 
temperature
drop of ~100 degrees from the carburetor enclosure to the manifold, 
this
temperature drop was with gasolene, and E85 should cool it further.




There is a problem comparing prices however; (I think Tom Jennings
said
it) 'we buy fuel in gallons but use it in Btu/mile'.  Because E85 has 
less
Btu/gallon it has to cost less per gallon to cost the same per mile.

Guess I won't need those Aluminum Heads
when the Turbos go on.


You can bet this advantage won't be lost on
the Automotive manufacturers.



FYI > :  E-85 in Venezuela is $0.17 per gal.
