Hi Dwain, Do you have any data on the efficiency difference between the EVGlide and a manual transmission? I'm looking to do an S-10 conversion in a year or two and am looking at one of the HPEVS AC motors. I'm planning a 100+ mile range so wonder if you know of or have seen any differences between the two setups, all other things being equal.
I assume you can adapt to most any motor?
