Supercharger Pulley Upgrade Help Please?

[SgtAbn]

Hi Guys, I have a 3rd gen T4R with a factory Supercharger in it. I want to upgrade the pulley for more boost; I know others have done this, but I have a couple questions please:
1) Does anyone know the part number and a source for an upgraded pulley please?
2) I've heard that upgrading the fuel injectors is a good idea if you do this; does anyone know the part number / source for the upgraded fuel injectors I need please?

I know some guys go with the 7th injector and methanol boost, but that is a little over the top for me. I just want to upgrade pulley and fuel injectors please.

I would highly recommend reading the megathread on all things supercharger. I'm on my second read through as I plan on adding one in the Fall.

Does anyone still make them new or you’re only able to buy used ?

The supercharger or the pulley? You can buy both new. Magnusson makes the SC and a few places make the pulley.

I recall reading a little while back that Magnusson had switched from the bolt-on pulley to a press-on pulley and URD does not make a press-on compatible pulley. I'm still waiting to see if they follow through with the newer style blower mentioned in the Supercharger thread.

I am curious to know whether that is vaporware or not as well.

You can find new superchargers for the 3rd gen T4r's at "Underdog Racing Development" 's (URD) website.
