Which belt to use with 3" upper and 10% lower on a 2.8 kb?

[jazz]

Im thinking about changing my pulley combo, right now have the 2.75 upper pulley stock lower (21-22 with headers). Boost should remain same with 3" upper and 10% lower. Just looking to add some tq with the lower...
Anyone running this pulley combo

Might want to hit Van up on this one. Are you running the 90mm idler?
