Doug has raced several interesting cars over the years. In 1991 he was the
UDRA nitrous pro stock rookie of the year. In 1993 he was credited with
being the first UDRA car to run a 6 second pass at 200 MPH. Bill Kuhlmann
and Animal Jim had run either one before him but not both. His current
house R&D car is a 6.40 Outlaw ProMod Mustang. The car features a 773
Ford Shotgun with 4 stages of nitrous. Naturally, as is so often the case, it
was only a matter of time before his work and his recreation would result in
a product for racing.

Today I would like to show you my results of testing and doing my
best to kill these Airnoids.
The Airnoids are beautiful
in their simplicity and
operation. A complete
system works like this.
100 to 150 lbs of co2 or
plain old shop air from a
10oz bottle is feed
through 1/4" tubing to the
Actuator which is a baby
electric solenoid. From the
Actuator the co2 is feed
to the Airnoids via 5/32"
