Summary
It is possible to belt drive and turn the 36 blower up to 3600 rpm to turn it faster than a gasoline engine.
This could take the vacuum pump up to 370 cfm at sea level and drive the performance up to 76,590 vacuum units.
So far to date I always seen all brands turn the vacuum pump to 3400 rpm for longer pump life.

Goliath Quad 6.6 vacuum is the 1st electric portable to exceed the vacuum performance of a 20 hp 36 blower truckmount.
Its smaller brother SBM-GO-A was the first to exceed the performance of a 33 blower truckmount at 42,500 vacuum units.

If you look at the Sapphire Scientific 370 Truck mount is not really 370 cfm as they only turn this unit at a 1 to 1 ratio with the engine.
When you look at the performance chart of the Ti406 http://www.steam-brite.com/gardner-d...c-p-12462.html blower and then scroll down the vacuum side of the chart and look at the performance of the blower at 3387 rpm, we are at 317 cfm open flow.
The 370 owner's manual states it turn at 3387 RPM

This makes the Goliath Quad 6.6 beat the Sapphire Scientific 370 in vacuum performance in both inches of lift and cfm.
