Ethanol is a weak choice as a fuel for internal combustion engines..
it does a good job fueling drunk people at bars tho??
Expensive to create competitively in Neat form..
essentially it becomes like a mime when mixed with Gasoline up to 10%
E10 has many combustion characteristics very similar to Neat Gasoline,
Vapor form Characteristics tend to be slightly different tho..
Stronger blends will pull more alcohol Characteristics.
which can be both a good & bad thing!
its a weak alcohol to use because you end up blending in a large% of alcohol to get small gains in alcohol characteristics you'd like in a *fuel*
unfortunately that same Larger % of ethanol will attack the fuel storage/delivery system even quicker than E10 does..
for the guy with the Turbo Evo wanting to run E85
you should worry more about your fuel lines turning to mush and clogging your fuel filter,
opposed to whether you have enough injector or if yer ignition timing is too advanced..
in general ethanol turns rubber fuel lines soft & sludgy..
Methanol will dry out & crack the rubber(like aromatic components of gasoline)
The alcohol guyz usually switch out to PTFE type lines (teflon/steelbraided is the usual choice)
u can also use Flourine enhanced rubber lines but they are SUPER expensive like $20/foot
and don't like Cold tempatures..
also oil changes are needed Much more frequently with E85
(alcohol use tends to turn the oil watery instead of dirty and dark)
i personally think you may be able to get away with slightly stronger blends with Ethanol
i'm assuming your engine was tuned on E10 close to MBT w/some cushion
Using a slightly higher% blend, MBT ignition timing may no longer be knock limited as it was on E10.. mostly due to the blended fuel's New chemical composition of more "alcohol"
but since you're Living in L.A.
you should analyze what your Goals are?
whether its MPG's, 20Psi boost / Power, or regulated Emissions
if you're just wanting to play Dr.Jekyll / Mr.Hyde with the car on weekends..
i'd suggest small% Meth blends into E10 pumpCrap
& just read the plugs real quick to check your ECU Tune's High blend tolerance.
BTW: i'm willing to bet a M20 style fuel destroys E85 on the Dyno & on the street..
i specifically had my stock internal SR20DET tuned on a M20 blend
we Spool'd a GT35R by 4800rpm on a DynoJet248
400lb/ft Torque
the Full-race website has dyno charts of GT30's that need their hyped up divided manifolds to spool that Quickly!!
(we used their old undivided type)
