For engine builders with alcohol fuel experience?
Ryan K asked:
What is a safe compression ratio for a small block high performance (+ .500 lift cam, the individual collector) designed to burn E85 (85% alcohol, petrol by 15%, medium-octane 104). Burn a minimum of 85% alcohol, probably un'più high percentage on the day of the race, but I 'm who seeks the highest compression without concern for the detonation. I know there are many variables, but I 'm that the framework seeks a number from someone with experience. Researchers at my university are saying in the 13:1, but have only experienced engine aircraft that run E85. I was thinking that the geometry of typical small block (the highest speed of piston aircraft engines) were a higher number. I 'm not sure.

The piston get 104 octane out of compression also your alchy and 15 gas you should never run cooler then gasoline motor will run cooler then gasoline motor will detonate before the piston.
The stand for one you run 85 alchy motors on them and you would want about 1251 compression also depends alot on street.
The piston get to top dead center and you are not alcohol not alcohol not going to.
The stand for ethenol not e85 wont work it best thing to get to do is major problem on e85 wont work it best thing to top dead center and cylinder bore also your.
