I don't know much about pulling tractors, but some of these sounded like they were turning alot more RPMs than normal.

Afterall an engine is nothing more than an air pump and adding more fuel without more air would be no help. I could see packing it tighter with more boost from a turbo, but how about non-turbo motors? Thanks,jim
