Underdrive pulley questions
I got the 2010 4.6 2v and want to try out the under drive pulleys. I can't find them for my specific truck but can find a ton for the 4.6 mustangs. are they able to go on my truck? Any help or links to ones that will work would be great.

Why do you want underdrive pulleys?
You wont notice any difference other than your butt dyno telling you to believe they actually work or help so you can justify the wasted money. Saving that little bit of rotating mass on a 6000lb truck will net you nothing. Invest in some smaller wheels and tires instead

A underdrive pulley system will let the engine spin up faster (not much difference from stock imo), so if you notice anything it might be a slight improvement in throttle response. With a custom tune to help eliminate the electronic throttle lag, the undrive pulley system should take up most any mechanical lag left.

Those things are used for high speed road racing. I had a friend who participated in that sport. You under drive the alternator and power steering pump so you don't ruin the battery or boil the ps fluid. You just need to ensure your cooling is ok. Unless you do this sort of sport, don't under drive the belts.
