E85 corrosion.
Im thinking of using E85 with my new motor. Being an alcohol based fuel, will it corrode a magneisum case like methonal will?

I wont use it for that reason
I contacted Caltex a few years ago as I wanted to use the E10 fuel.
They told me I shouldnt use it with anything with rubber fuel lines and steel tanks.

I think that E85 is overrated,
the V8s supercars use it , but I think they forced to 
Ask bigrudi
I think he uses it in his track car and he lives @ sydney.

Got this off wiki: If a retailer chooses to post octane, they should be aware that the often cited 105 octane is incorrect. This number was derived by
using ethanol’s blending octane value in gasoline. This is not the proper way to calculate the octane of E85. Ethanol’s true octane value should
be used to calculate E85’s octane value. This results in an octane range of 94-96 (R+M)/2. These calculations have been confirmed by actual octane
engine tests." [6]
I read it on samba, so it must be correct.

and its what engine were first invented to run in the first place.
stupid greedy oil companies feed people crap and control the industry.
Nothing wrong with ethanol, just need the right setup to run it. seems easier than a gas conversion setup to me ???

yeah gas convertion is stupid unless you go for full gas injection system which then it is worth it.
the brazilians have been running there whole country on blends from 85-100% ethanol and occationally on imported petrol when enthanol is short supply
since the late 80s-early 90s
vw actually helped to devalop the flex fuel techology way back then when they had a bad an enthanol shortage.
A nearlly fuel self sustanable country over 2 decades with nothing more than a few basic mods and an ECU upgrade (most times standard factoy
equipment) 
omg! amazing! (insert sarcasum)
dam it! I have run a car on prepwash with no differance in the way it ran. So whats this bad thing about enthanol?

We have two 2.3 litre EFi engines ready to go into 356 Speedster Replica's that will be running E85.
There are some good reasons to run it, it runs cooler, it runs cleaner, and it makes better power... The only reason I don't run it in my 1916 is
that I work fly in fly out and Leaving E85 in the tank for extended periods can cause the fuel to turn to crap, ruin fuel pumps, and clog lines. If it
is used in foam filled tanks, like race cars use, it can destroy the foam as well.

watched a back to back test with 98 octane and e85 in a vtec honda, IIRC made 10 more hp with a change to timing and fattend the mixture up. It was at
superlap at oran park a couple of years ago.

Higher fuel consumption as it has a lower calorific value like LPG.

Hotter than what?
It probably would run hotter than other race fuels.

yeah so what? you don't hear petrol people complaining about petrol having less energy per L than diesel.
the price difference between petrol and ethanol when buying at the pump vs the mileage you get out is about the same.
A mate of mine has a friend from his previous work as a spray painter at a mustang restro place, this guy has an xr6 which runs exclusively on E85 and
E100.
that car is insane! runs very well and actually runs more cost effectively than normal petrol.
he runs something like 12:1 or 13:1 ? cr though.
I seen the car, well done to that dude.

Pro ma sell a additive to stop jelling and i belive corrosion etc but for magnesium i'm not sure. i know guys that dont drain the system at all.I
also coated Gary Phillips blower roters as they were showing some signes of corrosion but that coating don,t like magnesium!There may be some coating
that will work ill look into it may be the oil drainback coating.With the A/FD i worked on we simply blew the fuel system out plugs out spin motor
over spray GIBBS/WD40 or the like in fuel lines and into the motor a bit of a pain but when your setting world records you do what you have to do.Ask
Pommie Steve Reed what coriosion can do to a barrelvalve/carb cross shaft it can destroy your car when the throttle hangs open due to corrosion!

Could be viable then as it would work out around $1.30 with the increased fuel consumption as long as the car purchase price was the same.

Methanol is very often tuned quite rich for several reasons and makes its way past the rings and into the oil, from memory it settles out of
separation and eats a hole in your sump in the off season! Something like that anyway

Enthanol has actually a netrual PH so its non corosive. The problem lies with sertain blends I think? between 25-70% enthanol to petrol blend it can
have a phase seperation between the water content of the enthanol and petrol blend. Therefore the water can seperate and sit inside the tank or the
main problem is in the bowl of the carby which then it can corrode the carby alloy.
Typically above or below thses %s of blend this doesn't occour so corrotion isn't a problem.
Makes sence to why they only sell E10 and E85.
E100 isn't normally available in climates where temp can get below I think 11oC because of problems at low temp and fuel vaporazation. In other words
when its cold E100 can be hard to start.

I wouldnt be worried about the magnesium but I would have a little concerned about the long term health of rubber fuel lines. I wouldnt be using
supercheap auto hose at all but especially with e85. If you went to specialist hose places they would surely be able to get you something e85 proof.
Its not just v8supercars that are using it. I would say 1/2 of amatuer club motorsport running turbos use it. If their times were slower they wouldnt
be.
