These are right from Vortech, so unless it is a custom pulley, it won't be 2.75".

Also, looking at the spec/flow of the V3 supercharger 500whp+ should be no problem at all with an air/air FMIC. I would get rid of the Stillen water/air cooling system and go back to the OEM plenum. That way you can put the MAF sensor in the proper location, and have a solid S/C kit capable of solid power.


A quick search...

Stillen uses a Vortech V3 head unit: 1150cfm (for an Si, and 1050cfm for the SCi)
GTM Stage II uses a Rotorex 38-91: 1075cfm (I think advertised as Stage II 600hp)

So an educated guess suggests that with the air/air FMIC mod, the Stillen kit would make 600hp. At least this time Stillen picked a good supercharger to start with vs. the horrible decision they made with the 350z.
