Our chassis dyno is based on the DynoJet Model 248 single drum dyno. This dyno features a 48-inch diameter drum and 1200 whp capability. DynoJet’s are known for their durability and repeatability. The repeatability is due to the simple fact there is only one moving part- the drum. Wheel horsepower is determined by how quickly your vehicle can accelerate the drum. By sampling the rotational speed of the drum the acceleration rate is determined. Once the acceleration rate known, wheel horsepower is calculated. No special absorbers or brakes are attached to your vehicle and you don’t need to know the weight or gear ratios of your car. The vehicle is strapped into position on the dyno, an ignition lead is connected to your vehicle and you’re ready for testing. For advanced engine tuning, additional engine parameters can be monitored and logged. We can provide Wideband 02, fuel pressure and manifold vacuum or boost.

If you would like to test your car at our shop, please contact us to set an appointment. Baseline testing (for three test runs) is $75.00 (no air/fuel) $100 (with air/fuel). Three test runs are accomplished to ensure the vehicle has stabilized. Vehicles that are not run at WOT often see an increase in power from the first to second run and the third run will usually overlay the second confirming the power has stabilized.
If you’re interested in extended tuning and testing, the Dyno may be rented for longer blocks of time.

Engine dynamometer testing is an important and integral part of an engine development program. The ability to accurately and repeatedly measure, control, and monitor the engine is the hallmark of the engine dyno. No other piece of shop equipment can match the overall test capabilities of the engine dyno.

Our facility is equipped with a Stuska Model 800 water brake dynamometer. Data acquisition and processing is handled by a Depac data logger. Recorded data is stored and displayed on a PC running Depac software. The Stuska Model 800 water brake is capable of absorbing 800 hp at 8,000 rpm.

With the rise in popularity of the chassis dyno, many people consider engine dyno testing expensive, unnecessary or redundant. A comparison of engine and chassis dyno capabilities can help determine which dyno will meet your objectives. Our engine dyno test package includes free chassis dyno testing to verify “installed” engine performance expectations.
