Paul, A friend of mine, after managing a dyno shop some years ago,
has recently opened his own shop doing both general repairs and race
engine (not rotary) work. But he is interested in the rotary and we
often talk about it.   He intends to install an engine dyno and I
want to make a pitch to him to get one that will work with our rotary
conversions.  Do you have any recommendations?   A quick search of
the Internet found a number of  dynos that were rpm limited to 4500
-- not of use to  us.      Jerry

Mazdatrix uses a Stuska. You might find one used on Ebay.
they have added a complete computerized data acq and control
system. Don't forget the dyno water cooling system. You will
need a five hundred gallon tank minimum. Ten 55 gallon drums might
work in series.  Racing beat has a small concrete room
buried under the dyno that holds a least 1000 gallons or so.
Otherwise be prepared for using a lot of city water to keep
the dyno cool. We are not just talking about keeping the engine
cool. You need to do that too.


Paul Lamar ...No rotor no motor.

A source for the water tank are old propane tanks that are no longer
serviceable.  Check with your propane gas supplier.

He has decided to purchase an eddy current dyno,  Not water brake.
I am going to build the adaptors for the rotary.   Jerry
