anyone using the 2.55 pulley for an ati p600b?
i know ati used to offer a 2.55 pulley but is anyone using one and....if so..do you have any problems with it... is there any upgrades that can be done to the supercharger like a 10 or 12 rib pulley.. setup. does anyone make a kit or..have pullies that would work on a p600b..i just want to get the most out of that blower.

There 12 and 15# pullies are 12 rib and the 8# is 8 rib.
The biggest advantage for the 600B is through more airflow and not necesarrily more blower rpms. Get a good 3.5 or 4" intake on the blower and there will be a big difference in blower performance.

ok here is the scoop. I am running the 2.55" pulley (15# pulley). I make a solid 12 pounds due to opening the air flow ie headers. It is an 8 rib set-up and it runs great!! The only thing to watch is to make sure locktite is used when installing the pulley. I had my s/c rebuilt last summer, because that pulley came off, so ATI advised locktite. They sent the s/c back with a loose pulley, so I put locktite on and tighened it up to around 75 ft pounds as ATI wouldn't give me a torque spec, but it has stayed put now for a couple thousand miles - like everything else just keep a close eye on it.

That's interesting..... when I had mine rebuilt they called me and asked me about the 2.55" pulley. They had to replace the pulley and wanted to know if I really wanted the 2.55". I said yes and they put a new one on. I confirmed it by measuring it when I got it back
