Bio ethanol & methanol

[Grant Monkhouse]

I understand that you have to use twice as much ie 2x the size on the injectors if you are to run these fuels in an engine, obviously a premix with these aswell, KB2T would be good. Is the premix to stop bore wash?
What are the benefits to running these fuels in an engine?
   More horsepower? Cooler running temperatures?
   Is it possible to get away with using methanol on a road car? As i believe methanol is hygroscopic? so you would have to use it all or i would suck in water? Advice please. Cheers

The rule of thumb is 33% more fuel.  A premix is absolutely necessary.  Any castor oil is acceptable as normal oil isn\'t soluble.  The premix would take the place of any oil injection that\'s still in use, which I would think should be removed.  

The benefit, at least for us in the US, is cheaper fuel costs compared to running a higher octane fuel as it\'s usually less than regular fuel.

The other, though this is arguable, is that it lowers operating temps.  I haven\'t seen any evidence of this yet, but I\'m not fully tuned either so I won\'t say one way or another.  

Ethanol is also much more hygroscopic than normal fuel, but I don\'t believe it\'s caused any issues so long as your fuel system is sufficient.  

Lastly, like a higher octane fuel, you can achieve more power with ethanol than not.  It has less energy for the same volume of gasoline, but the difference in the additional quantity used gives you more power.  It also has a RON of 129 (per wikipedia) thus less susceptible to knock, therefore, crank up the boost, or timing and you will make even more.

When I have my tune finalized, I\'ll be able to compare that with other fuels.

Any progress on this, as I considering running a full methanol system for my track car and would like some info.

thanks
