Sturman Industries - Engine Test Lab




DYNO LOAD & CONTROL
Motoring / Absorbing Absorbing
Sturman Industries’ engine test facility, located at 8,700 ft, is uniquely situated for high altitude testing. However, via use of a Combustion Air Supply unit, Sturman’s dynamometers are also able to perform testing down to sea level conditions. Contact Sturman to take advantage of our facility and skilled staff for your engine development and characterization needs.
