55,000rpm is maximum efficient impeller speed .
They have a 1.54 step-up.
I'm using a 3" and a 8", I'm spinning almost 57,000rpm. (14lbs)

If you have the single belt version, you will need a F-150 pulley.
I have 1 I will sell for $20.oo
If you have the twin belt version, you will need a 8" pulley.
The single belt comes with a 3" blower and the twin belt comes with a 3.3" blower pulley.
