JustGav Posted July 6, 2007 Share Posted July 6, 2007 It doesn't. If it took 10bhp to spin the pulley, can you imagine the rest of the ancilliaries? You'd need 200bhp just to overcome the extra mechanical friction. These pulleys often tend to be underdrive too, so the lower current from the alternator helps your ECU work better and the fuel pump shoves more under stress. Or maybe not. It won't make extra power, it may not absorbed as much power ie provide a ever so-slightly quicker pick up on the rev, however for the possible damage it can cause via harmonics to the crank, bearings, shells, tranny.. is it worth the risk (Try it, let me know..[Not directed at JohnA]) Quote Link to comment Share on other sites More sharing options...
