What makes more power: C85 or pump E85?

0:10 C85 vs Regular Pump E85
0:30 What is C85?
1:05 Ethanol content should be 70% which we confirmed
1:30 We had to cut ethanol content because we were out of fuel pump
1:50 So we technically have both fuels with 40% ethanol content-this will make for an even apples to apples comparison
2:00 Over 40/50% ethanol you don't see any more power
