Larger Crank Pulley

[getdowngranny]

Im looking to buy one of those larger crank pulleys that spin your accesories at a faster speed. I need my alternator to spin a bit faster at idle to keep up with the stereo equipment demands. I really dont want to put a smaller alternator pulley since I have a RJC billet pulley on it.

Larger?
Don't you mean smaller

he means larger but its not going to happen , there isnt a matchbook cover between the stock crank pulley and the waterpump pulley

go with the smaller alternator pulley (will also need a smaller belt too)
or a higher output alternator
dual batteries
or just have your idle raised while you play

Looks like ill have to look for a smaller alternator pulley. I already have dual optima batteries, 200 amp alternator, and a battery isolator. My issues are only present at idle, Once i get around 1000 rpm all is good.

put a dime in the throttle while you play

I have a back billet under drive crank pulley and matching alternator pulley-$75. Shipped
