FAQs About DNA Filters

The DNA Air Flow Tests

For the air flow tests, we use the most advanced flow bench available today. The ROTRONICS FlowScan, is a totally computerized flow bench that measures:

Mass of the air
Flow of the air
Temperature of the air
Absolute air pressure
Differential air pressure
Speed of the air at various points (Pit ot tubes)
Absolute humidity of the air

The complete procedure is automated and computer controlled, eliminating human errors.

The DNA Dyno Tests

For the Dyno Tests, we use the industry standard Dynojet chassis dyno equipped with eddy current load control, Dynojet 250LC. Our dyno cell is equipped with a variable flow air cooling system, designed to precisely simulate real world conditions.
