Originally posted by fingas: ok i slept through this part in physics but it is easy to see where you can free up power using a udp. Here is an experiment for you, get a round wooden rod and get a moderately heavy pulley shaped object that you can put on the end of the rod and try to spin it. Now put a similar sized but much lighter pulley like object on the rod and try to spin it see which one is easier to get started.
Yep, that shows how your engine will rev much faster with a lighter pulley. When you're in neutral!
