It won't last 40 min IMO.

Right now, I'm just anxious to get the whole thing up and running.

Mike may be able to help you out with an adaptor of some sort if needed. Not too familiar with buggies and truggies.

Is that optimal for efficiency? Would going with the 1515 at 2200 rpm be better just for the sake of being in that rpm zone?

2200 RPM would give you better efficiency I would think.
