Roots style Vacuum pump booster?

I was wondering if I hooked up a roots style blower from a truck mount vacuum system in front of my vacuum pump, and powered it with an electric motor, would it work as a vacuum booster, the pump is a welch 1397, if you dont know about high vacuum systems don't answer!

I don't know much about high vacuum systems, but I am pretty confident that you are talking about two pieces of equipment that are not going to work together. The truck mounted vacuum is designed to produce a one fifth atmosphere vacuum with 1700 to 5500 cubic feet per minute of air flow or lower vacuum at higher flow. The Welch pump is designed to produce something like 1.3 X 10^-7 atmospheres at 18 CFM.
