E85 does make more power some where 10-15 HP more, that being said it also uses about 30-35% more fuel. So not the greatest option for long races. As far as wear on the engine, no difference, however it will wreak havoc on your fuel cell if you leave it sitting in there. Running VP 110 or any higher octane will net you very little as far as power being that the CL10 engine does not have the compression ratio to take advantage of the higher octane. In some cases it hinders performance as the burn of the higher octane is slower. A fuel like VP110 will how ever act as a safety net to detonation and vapor locking in a race like V2R that has extremely high temps and elevation changes.Here’s a question for you fellow class 10 racers. Who runs e85 and what are you seeing in differences, wear on the motor, gas mileage, power differences? Can that sane power gap be bridged by running like say vp110 or a higher octane?
