Pressurized Dyno Room
If the air coming into the dyno room is greater
than the air leaving the dyno room, the room will
become pressurized. A pressurized dyno room
would make measured power misleading. To
compensate for this you need an equalizer box.
This box is basically a vent to the outside of your
dyno room baffled to reduce noise. The size of the
equalizer box is dependent on the size of your
dyno room and the size of your fans.
