Bob, I think you will find that dragsters run on methanol, which is a different
kettle of fish.
In Australia we have E10 (10%) supposedly 94?? octane. I won?t use it in my
Healeys as it is rubbish (2c per litre cheaper than 91 unleaded). One small
fuel company makes E85 which a friend uses in a Datsun 1600 (510) race car
fitted with EFI. He had to increase the fuelling by 30% from that for 100
octane Av-gas to obtain the same hp figures. The exhaust stink is sickly and
sweet and unbearable. Might be great for the environment, not good for humans
I use 95 or 98 octane in all my cars. For the low mileage they do, the extra
expense is negligible.
I totally agree with David Nocks comments in his recent email

Ethanol has a much lower energy content than gasoline, hence the lower mileage
with gasahol. See here:
http://www.afdc.energy.gov/fuels/fuel_comparison_chart.pdf
('alternate fuels,' not 'alternate facts')
It does, however, have a higher octane rating allowing the huge compression
ratios in dragsters and other racers; which is what produces the massive power
in those engines.

The correct AFR for alcohol (ethanol) is around 8 to 1 versus gasoline at 14.7
to 1. Switching to 10% ethanol should equate to about a 5% richer mixture.
Ethanol produces more power than gasoline ? hence alcohol race engines but much
more fuel required. Your mileage will suffer.
Best regards,
Jim
