10% underdrive pulley

[ilikerice]

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?

[MUSKOKA800]

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.

Mine never did, I have 1200 watt system in the Yaris and a 2400 watt system in the tC.

1200 watt rms system? because i couldnt even get a 1900 watt rms to work in my impala and if that works in a tc thats pretty damn impressive lol

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.
