I have been reading the past threads on the under drive pullies, in particular the Batterns one. I am just wondering those who have installed them on their windsors, what type of performance gain did you achieve (any reduction in 1/4 mile times), has anyone done a b4 and after dyno run??
Also has anyone experienced any problems with overheating?? or with any voltage problems?? is the power steering ok??
I didn't do a before and after dyno, but they have been shown to give about 8rwkw difference on a stock 5.0L. I found the increase quite noticably once it was installed, revs much quicker and more pull. I did have a little drop in charging voltage, especially when idling with head lights on, but haven't had any problems with it. Overall a great mod, how else can you get 8-10kw for only $200
