Re: Underdrive pulleys for ba xr8
Some of the underrive pulleys available, use no apparant harmonic balancer weight which has been blamed for some of the problems and they are meant for 4.6 motors not our 5.4, powerbond make a underive pulley that still retains a full balancer and I have not heard of any problems with these ones, but not to say there has been no problems.
If you beleive everything ford try to tell you, we would all leave our cars dead stock knowing that is the best power we will get and they will never be a problem.
There is no substitute for cubic inches but my pursuit sure closes the gap
*UPDATE * Pursuit has just run 11.763 and 116.18 mph making it Australias Quickest and fastest unopened boss as well as Australias Quickest and fastest naturally aspirated Boss
