I've been playing with E85 for a few years now and have been wanting to run in in my ITB Volvo, but the current rules do not allow for E85 usage.
After several test with the race car I have found that E85 is +-5 hp of a blend of 100 octane and 92 pump gas.
Due to being able to run more timing the E85 has more torque down low but doesnt have as much up top due to its slower flame front speed. Plus traditional gasoline has a very fast flame front that mean a high peak cylinder pressure.
So you gain some and lose some by using E85 in a NA car.
I would like to propose a rule change allowing the use of up to 85% ethanol in conference races.
The cheapness and availability of E85 in the northwest as well as its octane could be of use as opposed to a true race fuel.
Thoughts?
