My Ride: ESS TS2+ ZHP
The pulleys are marked on the front face with their size.

I don't have a boost gauge in the cabin for real time monitoring of boost. IIRC, back when I had the stock exhaust manifold and stock ZHP cams it was something like 10.5 psi. Forget what it is now with cam and header changes. Probably shouldn't be comparing numbers from different kits though.
