whipple pulley?
Does anyone know what size pulley I should run to obtain 8 or 9 PSI? And does anyone know of anywhere that makes an aftermarket pulley like Reichard Racing Pulleys?

my 5.3 kit came with a 4 3/8" pulley. a 4" pulley makes 9-10 pounds on my truck so i'd say a a 4 1/8" would put you about right. measure the O.D. of your current pulley though just to be sure. every 1/8" smaller is good for about 1 pound.
