Anyone know how big a factory pulley measures? My truck goes past the stock boost gauge in the dash but I herd they did that from the factory. I would like to measure mine tonight just haven't had time.

Did you check the crank pulley? is it the stock caged crank pulley? the stock boost gauges are crap, my truck with stock pulleys would show past 10 psi.

I was getting ready to buy it a blower pulley, but I was curious about it going past 10psi. It really isn't fast so I assume its stock I was going to measure it.
