Re: Larger crank pulley in, testing begins... (g60vwr)

I said this about the larger crank pulley before. It does get higher PSI but it does take a little longer to build up. Its kind of like putting 18s on a car Highway power but off the line http://****************.com/smile/emthdown.gif think of a larger crank pulley like shifting to a larger front crank gear on a bicycle its harder to push up to speed but once its in its proper RPMs it rolls really fast. http://****************.com/smile/emthup.gif

I would think that I larger crank pulley would actually rob power since it has to work harder to spin the alternator and a/c compressor. Sure you are spinning the charger faster, but you are also spinning the alternator and a/c compressor to higher speeds as well which causes more parasitic drag on the whole engine. If you want your charger to spin faster, just get a smaller pulley and save yourself the effort.

Re: Larger crank pulley in, testing begins... (joeZX6)

well i did peg 15lbs for a quick second last night...so i guess the slight loss of low end plus high end improvement is good. too much damn wheel spin in the first two gears to begin with anyway
