What upper pulley do I have on this?

[CompOrange-L]

Hey guys I recently bought a 2012 GT500 last week and I know it’s got 15% lower pulley but the guy I bought it from said he doesn’t know what upper pulley it has. If you can tell me what you think by the pic then that’s awesome or if you could tell me how to measure or find the markings that would help a million because I’m about to get Lund to tune it once I figure out what upper is on it. Thanks in advanced guys!

It's a Metco pulley, most likely a 2.6". They also make a 2.8" and 3.0" for their hub. With a 2.6" and stock lower, I was at 13.5#s of boost.

Congrats on your purchase. Over in the Superduty world, when we get our trucks tuned we say the feeling it gives us is Permagrin. When I got my GT500, it definitely caused me to experience it again.

On my old Metco 2.6" pulley, the 10-rib [VVVVVVVVVV] peak-to-peak diameter is 2.6". There are no markings on mine.
