So, Jackfish here again. Been reading through alot of the older threads on the site and i keep reading alot about an ASP Pulley. What is that? I clicked a link to the site and it said something about 900RPM full run.... NO IDEA what that means. Would love to know though. Thanks.
It has performance gains since the engine doesn't have to work so hard to turn all the accessory's. The engine winds up quicker too supposedly. I actually had one arrive at my house this morning, I'll be trying it out on one of the cars.
problem with smaller pulleys. once it starts to slip, it's a never ending problem.
got a 300zx that just burned through 2 new belts when it came to us with this problem. looking for a factory replacement right now. i've seen dozens through my years of wrenching that go back to factory.
