To clear up things,if I were to build an engine to run only on E85 rather than on gas and/or E85 and my target was 100HP engine output, would I be able to save weight on the car with the smaler engine and gain miles per gallon?
Octane is only useable if the compression ratio of the engine is high enough in the first place.
It appears that your santioning body is not willing to be the enforcer of the rules. If you state in your rules for the race that all cars must use the fuels as purchased from the track, then you can...
What is the highest compression ratio that E85 is able to run at without undue harm? What are the chances that the automotive manufacturers will make a car that can only run on E85, and gain power by using a lighter engine of smaller displacement?
You might check with the gasoline's supplier as many of them use an Isotrace florescent additive put in at the factory that shows if you have the real article,or if it has been adulterated. The use of the meter to check for the compliance of a sample is simple and quick,just standardize to a...
