That's an activity best left to experts in my opinion. It's certainly not for an amateur like me. I'd think you would certainly void any warranty you had left and take the chance of overstressing or over-revving your engine. If I need more power in a tractor, I'll buy a bigger tractor.
But that's just my answer and what makes me feel comfortable. That doesn't mean it can't be safely done by an expert. /forums/images/graemlins/cool.gif
