Ok, the plan is getting a little more solid. I'm grabbing a second Etek and going to use two for the project. That means 12hp continuous, and 40hp peak at 48 volts. Going to mount the motors right to the rearend with a gear reduction, and then create a whole "regeneration rig" with a small 15-20hp engine and 48V alternator designed for windmills. Seems a lot more complex than just doing a small 20hp engine alone, but I think this setup will give a lot better city mileage, and better overall power than just a small gas or diesel engine alone. I'm also looking at having the motors be mounted on the ends of plates that look like traction bars, so the whole setup can be transferred from vehicle to vehicle with ease. Here's a few pics of the Etek, for those who've never seen one. They're incredibly powerful for how small they are. Only about 20lb.
