I have a 95 Cobra and was thinking about adding a set of underdrive pullies. Now I know this question has probably been asked before but do the underdrive pullies really have any big disadvantages? I heard they decrease the speed of the accessories, which worries me because I have an amp and subs installed. Any help is appreciated.
You should be okay, the slow down isn't that much unless you have several large amps.. some folks with boom stangs need 2 batteries
I don't know..I installed steeda's and I can definately notice the dimness of my headlights when at idle compared to >1k...The interior lights are also much dimmer...
