Theory of Operation
A Dynamometer is used to measure engine power. Dynos
are either crankshaft dynaos or chassis dynamos.
Crankshaft dynos require the motor to be removed from the vehicle
and the power is measured
directly at the crankshaft. Chassis dynos
test the power delivered to
the wheelst. As such, the power figures measured are always less than with a
The PDA-Dyno™ is a newly developed device that uses the OBD II
data on all 1996 and newer automobiles to compute engine power,
acceleration times, fuel economy, and more.
The PDA-Dyno™ tests the vehicle in a completely real world situation that includes powertrain losses,
drag from disk brakes and wheel bearings, rolling resistance of
tires and aerodynamic drag. So, whether you drive a Truck or a
Ferrari, the power calculations will correct for wind drag.
The PDA-Dyno™ will
also correct for weather conditions and altitude. So, a vehicle dyno'd in Denver on a hot day will give the same results as a chilly day in San Diego.
Measurements generated are comparable with one another around the world.
Extensive comparison testing on the Dynojet chassis dynamometer has shown that the
PDA-Dyno™ is extremely accurate.
