A gasoline version of this car weighs about 2200-2300 lbs, 300 lbs heavier than mine is today. When I add the other battery packs it will be almost the same weight as gas.

Yes, it's "all about the batteries" as Bill Dube (owner of the Killacycle) would say. Not all battery choices can deliver high current. The motor can only deliver to the wheels what the batteries can put out. The battery packs in the Cobra are the same chemistry that Bill is using, nanophosphate lithium ion.

The eMotor is more like a gas transmission.
So its more like you put in an extra 200lb 10-speed transmission in your gas car to make it faster, which actually makes it slower because its heavier.

The power in an electric car comes primarily from the batteries and the controller.
