Pulley ?

[OneSlowV]

My dad just bought a 2008 GT500 anybody know who makes a purple pulley ? It's running stock boost levels 9.5 lbs

Pretty sure that is an older Metco pulley which may be discolored. They came in 2.6, 2.8, and 3.0". I would not assume you are only making 9.5#s of boost just by reading inferred boost on the cluster gauge. The 2.6" would generate 13.5# with stock TB and exhaust.

Does not appear to be a stock pulley... looks much smaller than the 3.0.

Any way to Measure the pulley that's on it ? Only reason I ask it feels like stock power to me before and I just got through putting a diablo intune on the car for him which made it run a lot better .

You should be able to measure with a caliper. http://a.co/9mbf21P
