luckily the aquariums have me in ownership of some big pumps, got a few to choose from, up to a 6000gph monster, but they're not so speed adjustable, so guess a NEMA 17 steppers going to have to get adapted to a knife valve for flow rate control...

Andy,I found what I was thinking about
:
SAE Paper# 860091,"Aerodynamic Drag Studies on Rolling Vehicles by Underwater Tow Testing," by Mark L. Vorwaller and Geoff J. Germane,Brigham Young University.
They pulled a 9.5" long,and 2" tall model under 2-feet of water,in a 42-inch wide trough,at 11.761 mph.
--------------------------------------------------------------------------
They also cite:
SAE Paper # 760189,"A Parametric Investigation of the Validity of 1/25 Scale Automobile Aerodynamic Testing," by M.E.Doberenz and B.P.Selberg.

SAE is online and you could probably order the papers or facsimiles, or download them.They might save you a ton of time.
