YOUR DYNO ROOM
This section is not meant to imply that a dyno room is essential to repeatable results
on a Dynojet dynamometer. However, a dyno room with an engine cooling intake fan,
exhaust extraction, and noise reduction capabilities can add a new dimension to your
shop.
S ETTING U P A D YNO R OOM
A proper dyno room design will help to ensure repeatable, accurate runs. A good
dyno room should do the following:
• exhaust extraction
• minimize noise
• provide a controlled environment for testing
• provide a view window (safety glass) for customers
• be designed with safety in mind
Exhaust Extraction—Exhaust extraction is needed to remove exhaust gasses,
especially carbon monoxide, from the dyno room. Carbon monoxide is potentially
lethal to people if not removed from the room and will affect engine power when
mixed with fresh air. Plans for exhaust extraction (P/N 73429201) are available from
Dynojet.
Engine exhaust contains poisonous carbon monoxide gas. Breathing it could
cause death. Operate machine in well ventilated area.
Intake Air Fan—After building your dyno room, you will need to supply a cooling
fan. The cooling fan supplies air to cool the vehicle’s engine while supplying fresh
oxygen for you and your vehicle to breathe. It is a common misconception that you
cannot tune a vehicle without a large fan simulating exact road conditions; however, a
good cooling fan is the only requirement for consistent diagnostics and tuning. The
installed fan should be at least 5200 CFM or determined by Industrial Noise Control.
Note: If the air flow rate coming into the dyno room is greater than the air flow
rate leaving the dyno room, the room will become pressurized. A pressurized
dyno room will make measured power misleading.
Fire Suppression—Always have adequate fire suppression or fire extinguishers in
your dyno room.
