prodirt, The short answer is a motor with a single wind will have more torque and slightly less rpm than a motor with 2 or 4 winds, given the same number of turns. The more winds the more rpm but it will take longer to "spool" up and not have the pull off the cornners. This is all relative to proper gearing.

I don't know of any production motor below a 6 turn. A 6 turn pulls alot of amps, so much that many sport speedo's can't handle the current.
