Champion R15B Air pump specs?

[slackdaddy1]

I have a champion R15B pump on a 80 gal tank but no motor.

I have not been able to locate specific specs for this Pump.

I am looking for CFM at pressure with specific HP motors and/or specific CFM (at pressure) for specific RPM.

I found specs on a few distributors sites, but they just list a range (3-7.5 HP and 9.7 - 23 CFM)
They also list CFM "displacement" but not CFM "at pressure"

I want to spin the compressor with a 1750 rpm 5HP motor, but don't know the RPM it should be and what CFM @ 90psi it will give me.

It takes a 7" motor sheave on a 5HP 1750 RPM motor. Pump spins at 734 RPM and will make 17.3 CFM @ 175 PSI. Dual stage pumps are not typically rated at 90 PSI since they pump pretty linear through their operational range.
