Mike, I probably didn't do a very good job explaining how this system works. So here is some info direct from the manufacturer's website:
"One of the simplest, and often overlooked components in the power industry is the tapered split collet. The significance of collets is seen through their widespread use in a variety of industries. The TRI-COLLET pulley system creates compressive forces that clamps a collet onto a shaft securing it in place. These collets are removable and re-positionable. When the clamp screws are tightened, the screws close the collet onto the shaft creating a nearly uniform distribution of forces around the shaft, resulting in effective holding power.
The TRI-COLLET pulley system is an ideal way to attach pulleys to shafts for high torque applications where press-fits and keyways are not desired. "

INSTRUCTIONS FOR TRI-COLLET PULLEY SYSTEM
Installation:
Refer to Figure 1: Exploded View of TRI-COLLET Pulley System
1 Remove the breather nut from the end of the supercharger shaft. When reinstalling breather nut use sealing tape or compound.
2 Remove factory pulley with suitable pulley remover. [Figure 2]
3 Slide split collet on shaft approximate 0.330" from end using the included measuring strip. (Note: Collet is pre-strained for your convenience, if collet is too tight on shaft to slide, pry gently at split to loosen). [Figure 3,4,5]
4 Apply "never seize" or similar anti seizure product on outside of collet (do not apply "never seize to shaft). No compound is included, this is an optional step.
5 Slide pulley over shaft and collet until it seats with collet. Rotate pulley to align through holes with threaded holes in collet.
6 Place lock washers on (3) 10-32 socket head cap screws and apply an appropriate amount of the included thread locker to threads. Insert screws through clearance holes in pulley and thread into collet [Figure 6]
7 Tighten cap screws evenly to 60-70 inch/lbs NOT ft/lbs. Use caution, 65 in-lbs is approximately 5 ft-lbs! [Figure 7]
8 Ensure that front of pulley is flush with shaft (Note: if pulley is not flush with shaft restart installation adjusting the 0.330" dimension accordingly. See page 2 for pulley removal instructions) [Figure 8]
Removal:
Refer to Figure 1: Exploded View of TRI-COLLET Pulley System 1 Remove the previously installed (3) 10-32 socket head cap screws.
2 Insert the supplied 1/4-28 socket head cap screws in the threaded holes on the pulley and apply even torque among screws until pulley is free from collet.[Figure 9]
(Note: Collet removal is not required for pulley swap. If collet removal is necessary, remove breather nut and slide off shaft. If collet is too tight on shaft to slide, pry at split.)

There you go Rob.
They only go down to a 2.8" because you need to have your snout machined for anything smaller than that. I did speak with a rep from their company about 1-1/2 years ago about custom pulley sizes. They basically told me that they can do it, but the cost will be around $20 more then they currently are.
