Yeah. Try to run E85 in a sled. That should be a good time. 

Not ideal for a trail sled for sure unless you had a short range and a good supply

Without seriously pre-heating the engine, specific cold start only tune or blending down the ethanol content, that bitch ain’t gonna light. I’ve seen it in the automotive world plenty. Sled engine management, fuel delivery, etc isn’t gonna pull it off any better. 
 

All the big Cat turbo guys I knew back in the day were on race fuel for hotter tunes and spray meth (washer solvent) if trying to run hard on the trail.
