Bridgeport Boss Second Z Axis?

I also do not have a GIANT air compressor, most I see run on air.

I think you misunderstand what is meant by a "spindle speeder". These are purely mechanical device (usually an epicyclic stage) that implements a step up gear ratio of around 3 or 4 to 1. The tool then rotates at 3 or 4 times the spindle speed. However, if you have a separate high speed spindle, it's not relevant.

So this speeder uses the original spindle motor as a power source and speeds up the output? If so I have yet yp find one for a QC30 tool holder. If you can point me in the right direction I would be much appreciative.
