Default Corvette Air Pump Pulley Kit

Looking at getting a Corvette Air Pump Pulley Kit for my 91. Is it worth it and what is the best price for it? I do not want plastic.

I think its worth it for the weight loss and the better look of the engine bay. It really makes it look nice without all those stupid *** hoses running all over the place.

I had my TPIS pulley installed last week and I took the car for highway driving last night and believe it or not, there was a difference in takeoff and power. Without question there was an increase in TQ & HP (for me at least).

I had March pulleys with a 90.5 inch belt. When I put the TPIS air pump pulley on, I had to go with an 89 inch Dayco. All is good here

Alternator should have no worries.

Well maybe it will help you to know that in January when you are driving the vette we will have 2 feet of snow and it will be 10 below zero. So that has to help you some.

Put it on for inspection, take it off after or get an illegal inspection, or an emission exemption...there's options.
