    New Trick flow Underdrive Pulleys

    Flippin through my newest Summit Racing book today and came across Trick Flow UDP...crank and alt for 209.95! The crank pulley is 25% underdriven and the alternator pulley is an overdrive to keep voltage up. They aren't on the site yet, but the PN is #TFS-18012. They sound like a good deal to me since you get both. What kinda gains do you guys get with UDP's?

    Damn right! That is an AWESOME price too! I really liked the power increase of my truck after I got them on. Best bang-for-the-buck mod out there...

    warlock2007, your best bet would probably be to go on the summitracing.com site and order a magazine, or their # is 1-800-230-3030 call them up and see what they say. When I get money next week I'm orderin a set for sure!

    Just no alt overdrive pulley. Cold weather for me I want my alt to turn its normal speed.
