Upper Pulley Help

Was looking into upgrading from my 2.8" to a RR 2.65". What are your alls thoughts on that pulley?

Not really a problem and you better have some good belt wrap for no slip. It's a little on the small side lol.

Great fun if the fuel is there to back such a pulley.

have you all seen anyone with a 2.65" and what kind of numbers?

I actualy went back to a 3.0 upper and 2 lbs lower. Same 18-19 psi with no belt slip. Made 558,526 three weeks ago. On clayton dyno, it reads alittle low.
