Underdrive pulleys will turn both the water pump and the alternator slower. Bad idea. That used to be the hot ticket for beginners 10 years ago. We know better today.88 Lx 50 said:im going to install underdrive pulleys and from what i hear every1 on this forum says not to unless ur gonna follow up with and electric fan and its also a cleaner look
Did I miss something? 6G alts? Where was I? :eyepoppinFoxChassis said:If you insist on underdrive pulleys and an electric fan, a higher output alternator is not optional, it's mandatory. And not an upgraded stock (2G) alternator. That'll still give you crap output at idle. Go 3G, 4G, or 6G.
