But yeah, I did a quick eyeball of the pulley alignment a few days ago. I centered the belt line of the griptec pulley/hub over where the belt currently sits, and it sure looks like the hub and shaft should be about even. Not exactly scientific, I know.

I’m waiting to do this swap until after I get back from the drag strip this weekend. I want to see what it’ll do with stock boost first.

By the way, which belt did you use?

Here are some pic's of the pulley installed with some measurements.

I used the factory belt since it still had plenty of tension left. I would say another thing that helped is the grip tech pulley grips the belt a lot better than the factory pulley because the boost seems to be more consistent then it was before.

I went from a rough 9 psi to a strong 11 maybe 12 psi. of boost now.
