Supercharger pulley

[fenda]

Hi guys have recently got a charged 99 vt, want to do the boost upgrade so went n had a look at the pulley, its the only shiny one on the engine and measures roughly 8.5 in diameter( using a scabby ruler that is). Which leads me to the assumption that already has the 10psi pulley added. It also has the 5 allen key bolts like iv seen i all the mace/fit sites. Im unsure as to what the standard pulley looks like,if anybody could confirm that it is already upgraded and i dun need ta spend another $400 that would be great, im just confused coz the previose owner didnt mention anything about the pulley. Cheers guys

sounds like it. the "10psi pulley" measures ~87mm. the MACE style pulleys are a modular system, which has a hub that the pulleys mount to, thus the 5 allen bolts.

standard one is one piece, usually grey in colour.

Yep you def have the upgraded pulley. Standard one is pressed on without any bolts.
