A.Rozell Posted February 14, 2012 Author Report Share Posted February 14, 2012 Just the normal front engine pulleys. I have a stock motor and just want to know what people are talking about lol. Quote Link to comment Share on other sites More sharing options...
feece08 Posted February 14, 2012 Report Share Posted February 14, 2012 The only thing I can think is you heard someone one talking about pulleys for a SC (supercharger) , when u change a pulley on a SC to a smaller one you get more rotations, therefore creating more boost. Other than that you can change your tensioner pulley to a HD one Which will hold up better.(usually used in boosted applications) also many upgrade to a 8 rib setup which helps with belt slip. Hope his answers your question.. Quote Link to comment Share on other sites More sharing options...

The_aSSet Posted February 14, 2012 Report Share Posted February 14, 2012 You shouldn't be worried about pullies unless you're supercharged Quote Link to comment Share on other sites More sharing options...
chpspecial Posted February 14, 2012 Report Share Posted February 14, 2012 (edited) Underdrive pulleys slow down all of your accessories like alternator, water pump and a/c compressor. This creates less parasitic power loss and in turn releases a few HP at the crank. Anywhere from 5 to 15. However, there is a draw back, slower accessories can lead to inproper electrical voltage at idle, or in adequate cooling due to a slower running water pump. You definitely do not want them if your supercharged. sent from my thunderbolt Edited February 14, 2012 by chpspecial (see edit history) Quote Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted February 15, 2012 Report Share Posted February 15, 2012 I've been running the underdrive pulley as long as i can remember owning the truck. On my stock set up they made very little or no difference at the track. Spend the money else where Quote Link to comment Share on other sites More sharing options...
