Subject: Dyno Time Available

I'm happy to announce that our Superflow SF-901 engine dynamometer
is (finally) operational. Our system is set up to make it easy to
install rotary engines (unlike most shops that are set up primarily
for V-8's). The dyno is equipped with computer throttle and load
servos as well as computerized data acquisition. This means that
specific test programs can be written and the dynamometer will
execute them automatically. Manual operation is of course still
possible, and is even desirable for certain types of testing.

Engine dynamometers are invaluable tools for controlled testing and
tuning of almost all performance-related engine variables -- intake
manifolds, porting, fuel and ignition calibrations, exhaust systems,
etc. "First cut" transient tuning can also be performed, but
validation requires in-vehicle testing. Likewise, application
sensitive systems (such as radiators) cannot be reasonably tested on
the dynamometer. But for basic engine development and performance
mapping, an engine dyno can't be beat.

Our normal rates for dyno time will be $90 per hour, not including
fuel and other incidentals. This includes my own time (as much as
necessary) and a technician for work that doesn't require my
expertise. I'd like to offer a special ACRE reader deal... $600
for the first 10 hours (minimum charge), additional time billed at
$70 per hour or part thereof.

Because of the nature of our current set-up, full day dyno time is
best done on Saturdays and Sundays. Installation and programming can
be done any time.

Anyone interested, please call me at 516-656-5685. Thanks, Jon

Wonderful Jon. Thanks for the offer. I hope you will be able to
provide non proprietary data on many aspects of rotary engines as they
are tested on your dyno. Right now I am mostly interested in: 

The stock water pump flow rate as a function of engine RPM.

The pressure drops throughout the cooling system such as
at the output of the block, output of the water pump and the input
to the water pump.

Water temp at the input to the block and water temp out of the block.
I assume you are using a tap city water supply to cool the engine.

Cylinder head temp near the base of the leading spark plug hole
as a function of RPM and throttle opening.

HP curves for whatever manifolds are tested.

HP curves for whatever exhaust systems that are tested.

BTW I know these questions will come up; 

Where are you located? Address phone number and email address.

Can you supply a test engine if somebody wanted to test an intake
manifold or exhaust system?
