Ethanol - Pros & Cons

HELLO EVERY ONE!!!!!!! if you want to corrode the shit out of your cars keep using e85. Our cars are NOT designed to run E85

HI ROBBO!!!!!!

HELLO EVERY ONE!!!!!!! if you want to corrode the sh*t out of your cars keep using e85. Our cars are NOT designed to run E85

There are alot of myths flying around about E85 and pretty much all of them are false.

Except the one about making butt loads of power.

But they are designed to run with 10% ethanol aren't they???

I have used United's "Boost" (10% ethanol) and it HAS increased power and bettered fuel economy.......

Ethanol has a higher octane rating than the same equivalant petrol. This is why people are getting more power out of their cars when running the E10 or 85.

As for the fuel economy, the ethanol is less dense than equivalant petrol, thus more is needed to produce the same amount of power as before.

As for being corrosive, my 27 year old Fiat has been running E10 ever since it came out, mainly using shell E10 or united. I didn't modify the motor at all, nor the fuel system. Not one item has become soft, broken, etc. the motor is still fine internally (head gasket blew for a different reason so I checked all that crap) with no corrosion. Plugs don't seem to last as long though. Make of this what you will.

Another big PRO is that if they ever release E100 (pure ethanol) then we can all get pissed when ever we want by the side of the road or where ever we want, just by syphoning the fuel tank. ethanol is MOONSHINE!

Bet the big brother ba$tards decide to put enough petrol in it to make it undrinkable

Does you 27 year old fiat have a fuel injection system with a high pressure pump,silicone seals, silcione rubber fuel pressure reg diaphram and injectors with composite components inside them?

Are you saying you got 20-25 % more power just by using E85 or was that with of combination of tune, injectors & E85.

Cause I really couldnt see that much increase just by changing fuels.

You have to change the tune - E85 has a different stoichiometric ratio (more fuel per litre of air). Hence the comments about upping jet size. In a carb you would need about 30-50% more jet AREA (not diameter) I would say.

With no changes and a flat across the board 20% fuel increase on the maps, it made about 35 more rwkw. We added a little more fuel, boost and timing (about 4 degrees), and got great results. See attached dyno graphs. Whats important to note is in the top end we're running approx 2-3 more psi, and gain about 60-80 more rwhp. Note the torque increase in the 2nd graph (ignore the AFR we were still playing with that at the time).

nope, but my fathers 21yr old Fiat does, as does my mums 25yr old ex fiat, as do MANY of my customers cars.

To this day haven't seen any problem of corrosion, either engine internally or in the fuel system.

E85 will not harm those components.
