found this on the net, quite expensive, but different, i would imagine it would be hard on the crank.... http://www.alphamaleperformance.com/pages/1/index.htm
i donno about it working to well or being good for the relyabulity(sp) of the car. the website doesnt explain well enough how it works well enough just that it gives you 100lbs/ft on demand...
Looks alot like an electric kart motor to me. So, what does this thing do exactly? Add extra twist to the crank? How does it keep up? One of two things will happen, the motor will out accelerate the electric motor, or the other way around, how to they compliment each other? Total bullshit.
