David I have an EVGlide in my own S10. I originally built this conversion several years ago with a clutchless manual tranny. When we developed the EVGlide, I used my truck for testing purposes. It was hard to tell any difference in range. What I did notice was the control. With the manual tranny, you had to pause at neutral to allow the syncro's to control the gear speed before engaging. There was a tendency to wear out syncro's after a short time. With the planetary and hydraulic clutches, shifts were quicker, smoother and no clashing. With the manual tranny, getting on the on ramp and trying to blend with traffic was dicey. That pause to shift while going down the on ramp made you pucker up. With the EVGlide, you floored the throttle and shifted at 40 to 45 without letting up on the throttle. Much more comfortable in traffic. If you build with a manual tranny and clutch, you will need a flywheel. That will temper your acceleration and deceleration. The HPEV motors have the same mounting configuration as the WarP9 and the WarP11 and fit our adapter plates. I have a customer who is mounting our EVGlide to HPEVs tandem motor which should make things exciting. He is just starting his build, so I don't know how it will work out. I have another customer who is mating the EVGlide to a special built eleven inch GE motor. This is going in a Cobra kit car which weighs less than 3000 lbs. with batteries. You'll probably see him at the drags. Try our web site for more information, kansasev.com.
