Rich Posted December 3, 2006 Share Posted December 3, 2006 what is the general opinion on this crank pulley and accessory pulleys over a BL crank pulley? http://www.mvpmotorsports.com/Templates/frmTemplateP.asp?CatalogID=250&Zoom=Yes&SubFolderId=204 Quote Link to comment Share on other sites More sharing options...
Gamer Posted December 3, 2006 Share Posted December 3, 2006 You can get everything there except the crank pulley. The UR Crank pulley is not dampened. Most people go for that kit minus the crank pulley for that reason. I am running UR pulleys/cam gears and a BL crank pulley. Quote Link to comment Share on other sites More sharing options...
Jake Posted December 3, 2006 Share Posted December 3, 2006 Why would you want a slower running water pump, altenator and PAS pump? Quote Link to comment Share on other sites More sharing options...
Gamer Posted December 3, 2006 Share Posted December 3, 2006 Why would you want a slower running water pump, altenator and PAS pump? I am fairly sure it is only the crank pulley that is slightly smaller. The rest of the pulleys are normal size. Quote Link to comment Share on other sites More sharing options...
Rich Posted December 3, 2006 Author Share Posted December 3, 2006 Why would you want a slower running water pump, altenator and PAS pump? sorry just used the search facility(what I should have done in the first place) found plenty of interesting info to put me off the UR racing crank pulley. will go for a BL one due to the damping and as you say slower running accessories Quote Link to comment Share on other sites More sharing options...
Ian C Posted December 3, 2006 Share Posted December 3, 2006 The whole point of getting an underdrive pulley is to specifically slow down the accessories, and thus 'save power', i.e. less parasitic drag on the engine I had one once, noticed no great difference, got scared of my crank snapping, went back to the stocker, noticed no great difference except I could sleep at night again -Ian Quote Link to comment Share on other sites More sharing options...

The whole point of getting an underdrive pulley is to specifically slow down the accessories, and thus 'save power', i.e. less parasitic drag on the engine I know, but still - sod that!
