Group Buy Question - UDP/Balancer

[Heather inOC]

What is that thing? 16 hp seems like a pretty decent gain, but I don't know what a 'balancer' is.

It's the main pulley that drives the belt that drives pwr steering pump, altenator etc. Do a search and you will find a detailed explanation on it.



This is from the web...



Underdrive pulleys do just that, they underdrive engine driven accesories by changing the diameter of the pulleys. Smaller pulleys on the crank and/or larger pulleys on the accesories(power steering pump, alternator, etc). This makes the accesories spin slower, thus consuming less power. Beware however, underdriving your accessories too much can cause problems like not having enough power to keep your battery charged or run a large stereo system. If you drive relatively slow these are not for you. Only aggressive drivers should really consider these.
