So I was told my pulley would be at the store in three days and over a week later it finally arrived. And when I ask the guy who ordered it for me how come it took way longer then he told me, he tells me that's how long it normally takes.

I will never understand some people, why tell me three days if you know its going to be at least a week. Sorry for the little rant, its just irritating.
So after making a bunch of trips to different part stores to find a belt that fit, I finally fired it up and to make it worse there's almost no difference. I'm now up to 3psi@2000rpm and my max is 6@3000ish. So I'm at a loss, any ideas?
Thanks for all the help so far guys, I forgot to mention that earlier. I really appreciate it.
