I have a new version of the VMP 2.3L TVS blower available with interchangeable upper pulleys. This was intended to allow road-course drivers to lower boost when they need less power (and less heat) for the road course, along with allowing you to run stock fuel system with an OD lower.
I use a stainless steel 6-bolt hub so it never rusts, with black annodized aluminum pulleys. As an introductory price of $3599 the blower comes with all 3 pulley rings at no extra charge.

This blower still retains all the great features of the original VMP TVS, including a high-flow inlet elbow CNC port matched to the blower, along with a 1 year warranty. The blower is delivered to you with the hub pressed on, no gaskets or other parts are needed. It is a direct replacement for the stock blower and utilizes all factory bolts and vacuum line locations.
This table shows the approximate boost with various upper and lower pulley combos:
17psi and below does not require fuel system upgrades.
Here are some dyno results from GT500s with the VMP TVS:
