ilikerice · 10-14-2010, 08:35 AM

quick question. about to purchace underdrive pulley kit. but whats the difference in the 10% pulleys and the ct-lite pulleys? are the 10% actually lighter than the cheaper one?

Being smaller the 10% underdrive is likely slightly lighter. But the main purpose of the 10% underdrive version is to reduce the accessory load on the engine (turn the alternator and AC pump slower) thus freeing up a engine power for increased performance.

you should not get an under drive pulley if you have a system. Get the lightweight pulley instead.

An under drive pulley and any type of system will lead to a constantly dead battery, even with upgraded alternators and the like.

Well yea, but I am sure you did it the right way. I remember one of those audio guys in the forums was complaining about the dead battery and he had all sorts of crazy stuff going on as well.
