4.6 Udp

[fyrfyter612]

Anyone with a 4.6 running an UDP setup? Summit Racing sells their own brand setup for 4.6 Mustangs and I'm gonna check if they'll work on the Explorers. I can't find any specifically made for the Explorer. Anyone have one made for the Explorers...and if so any problems running with it?

I have the ASP UD pulleys. I was told the Mustang ones will not fit. I do not know why. The part number for the ASP's is ASP527374. It did seem to free up some hp, but I haven't really seen any gain in mpg's. I have had them on for a couple thousand miles or so with no major problems. You may notice a dimming of the headlights at idle if you are running other accessories (i.e. ac/heater fan) and the ac/heater fan will run a little slower at idle if it is on high. Those problems are so minor that I don't regret getting them. You will be able to use the stock belt with them also.
