building a flowbench is next on the plans

I think I am leaning toward this setup

I was thinking about this

http://www.performancetrends.com/ez_flow_system.htm

But to be accurate with a orifice from what I have read about flow benches, combined with my 22 years measuring gas flow and pressure on semiconductor equipment you need to change the orfice when you change ranges.

I also found one of thies on e-bay but it is the 2.0" and that would not handle enough flow. see www.audietech.com


For vacuum pumps I was thinking about starting with 6 2 stage pumps that flow over 100 CFM so the flow should not drop off as fast @ 28"water I will build it to hold 8

Anyone here use a flowbench? I have ported heads w/o using templets but I want to move up a notch

I picked up 10 of the motors I wanted on e-bay for 179.50 for all 10 when I made the last post I was planing on spending from this site http://www.centralvacuumfactory.com/lamb-ametek-11603613-2stage-vacuum-motor-volt-p-448.html
169.00 each but I wanted this 2 stage pump so that I could maintain the same pressure drop at higher flow rates I did a cost benefit analysis and to get accuracy at higher flow rate was worth the 1014 ( plus shipping ) for the first 6 pumps because I could add more of the same later.
Hows that for luck I decide what I want then find it cheep ( I wish that had happened with my Warn OD for my jeep LOL )

Never seen anything like that before...couldn't you pick up a used superflow 120...I've seen them for $250...great bench

I looked for a used flowbench here in Co no luck so I will just build one blowers just came in today.

On a related note I have the air compressor setup in the shop had to use the cherry picker to unload it but I got it to the shop. First progress in a few weeks but I have been busy....
