[Land-speed] alcohol

[Tom Bryant]

Tom,

Because of the distance that we run, I would not think that eliminating the
cooling system is an option, but you can somewhat control the engine temp by
jetting. You can run a lot more compression than I can get in a 300 inch
Chevy, at least 16:1, maybe more. The best I have been able to get in my
motors is a bit over 13:1. I wish I could get more!

I run a mechanical injection so I am not conversant on running alcohol in
carburetors, but I suspect you have the same issues. Alcohol must be flushed
out of the between events or problems arise. I have had to disassemble the
fuel pump and clean out the residue because of negligence in this area . The
rubber hoses will harden over time and have to be replaced, also.

I like alcohol because it runs cooler (we have always had high temps with
gasoline), cleaner and is supposed to give more HP, but so far I have not
been able to exceed our gasoline speeds by that much. Also, as I understand
from what I have read, you should use more ignition timing, but it seems
that doesn't work for us either. Maybe someone can tell me what I am doing
wrong.

What considerations do you have to make when using
alcohol fuel? Is cooling the engine an issue? what
about compression ratio, parts compatability, etc)fuel
pump, carburetor, fuel lines and such) Could I
eliminate a cooling tank/ radiator?
Thank. Tom
