I'm thinking we're having a terminology problem here. A "roots blower" in my industry (semiconductor) is a high speed rotary type vacuum pump used in conjunction (usually mounted atop) of a more efficient (lower base pressure) vacuum pump attached to the low side. These are used to create a vacuum in whatever is attached to the high side of the blower. These blowers are meant to speed the evacuation of a large chamber and should not be run stand-alone. They are not meant to be compressors so perhaps our terminology is different.

Touche'. See what happens when you get pigeon holed in an industry and take a name for a generic description? "laughs"

The gold standard for performance tests is the ASME power test code... that may be overkill for what you are doing. Is it a shop test or a field test?
Basic parameters you will need to measure include:
Suction pressure and temp
Discharge pressure and temp
Flow
Gas composition
Pressure and temperature measurments should be made close to the machine. Temp needs to be taken in a thermowell that reads the temp in the main part of the flow.
What is wrong with the original equipment manufacturer's published performance curve?
