Paul,

   The "brain trust" had proceeded quite a ways toward defining an
   inexpensive package of hardware for recording intake and exhaust
   pressure pulses. Could this be finished to the point of defining model
   and part numbers with suppliers and prices for all the items needed for
   a complete system - including the PC software?

   I'd like to see if it would be practical to assemble a package in time
   for your next dyno run. Perhaps we could share the cost if it's fairly
   affordable.

   My dyno run is coming up soon. I'll be out of the country starting
   on the
   9th of Nov for ten days so it will have to be in December.

   We need at least two pressure transducers. I have one of Tracy's systems
   with the dual transducers so I can set that up. All one needs now is
   a data
   acq system that samples the sensors once every millisecond or so. I have
   a Tektronix storage scope that can do that. A battery powered
   digital data acq
   system with a USB output would be more convenient.

   What I really need is a body to take charge of this part of the project.
   Where are you and what are you doing around the first of December?
   Do we have any other electronic types that will volunteer?

November and December are out for me.  January and February should open
up.

It looks like you have the pressure transducer detail solved.  What
would make a good data acquisition board with a USB output, and what
software would we have to use with it?

I'd like to find something that's more solid numerically than snapping
pictures of an oscilloscope screen.

If you get a recent copy of Nuts & Volts Magazine or Circuit Cellar there are some adds
for data acquisition systems. http://www.nutsvolts.com/
