[Bradleypro]

Just added ysi onto car along with 8 rib kit but with different water pump pulley and at I 20% od balancer. And the belt keeps popping off one rib. Help please. Tuner says the belt is aligned fine when he cranks the car. But after a min or two popps off a rib

With the 20% OD balancer you have to run the JPC water pump pulley.

I have seen 1 car pop off 1 rib on the blower pulley from the belt being too loose.
