Does anyone know how much the Reichard ultra grip pulley is? I've e-mailed them but no response so far. I have a P1-SC with a 12 lb pulley but only making 8 lbs of boost. JMS is building a forged shortblock for me and suggests that I move to an 8 rib setup. I thought for added insurance I would use the ultra grip also and crank on up to 15 lbs of boost. Hoping for a solid 450-475 rwhp soon. Thanks.
