In simple terms of horsepower and miles driven per hour, you can instantly see just how well your vehicle is performing. Furthermore, the service technician can determine what must be done to upgrade your vehicle's performance.

Steep grades can be duplicated on our dynamometer. To create a hill, the operator presses a switch on the remote control computer in his hand and immediately the hydraulic power absorber grips the rollers making it more difficult for the vehicle's power train to rotate them. Naturally, the engine begins to work as it would in pulling the vehicle up hill. The roller resistance may be varied to any degree. The response of the vehicle engine to every road driving condition can be observed in minutes. To do the same by a conventional road test would require at least an hour and up to forty miles of driving.

Years ago, engines were simple, as was tune-up equipment. The mechanic's tool box contained feeler gauges, a spark plug gaping tool, and a timing light; later, dwell meters and RPM gauges. In recent years, electronic engine analyzers, or "scopes", and infrared exhaust gas analyzers have made their appearance. Engines have become ever more complex, along with fuel injection and emission control devices. It is no longer possible to "listen" to an engine and simply make basic adjustments. Today, more sophisticated tools and procedures are required to perform a tune-up. Using these sophisticated tools with the dynamometer gives the mechanic what he needs to find the problem under a variety of driving conditions.

A typical dynamometer operation will have instruments to read the speed and horsepower of your vehicle while it is being run on the dyno. The speed meter shows the exact speed the vehicle travels on the road, irrespective of the tire size, wheel size, or make of vehicle. It tells you the accuracy of your speedometer. The power meter shows whether or not the vehicle has reached the horsepower figures set by the manufacturer.

Before the days of the service dynamometer the mechanic had no way to tell exactly how much horsepower a vehicle had when it came into the shop, nor any way to prove that the lost horsepower had been restored by the work performed. With our dynamometer, you can see what you buy in the way of service to your vehicle. Horsepower and better performance are actually weighed out and measured before your eyes.

In short, our dynamometer can mean as much to you in buying automotive service as an accurate-reading service station fuel pump does in the purchase of gasoline. You see what you pay for in terms you can understand...horsepower and miles per . That's because the mechanic, working with the dynamometer, actually performs the miraculous feat of taking your vehicle out on the road with all his modern test equipment flying with him. The vehicle trouble you may have experienced shows up on the dynamometer just as it did when you were driving at highway speeds.
