Frequently Asked Questions

When preparing your vehicle for dynamometer testing, please ensure that:

1. Vehicle is not leaking. This includes: gasoline, coolant, oil, brake fluid etc
2. Vehicle is not visibly burning oil
3. Tires should be broken in (not brand new)
4. You notify us in advance if you are running open exhaust
5. Vehicles exceeding 400 hp have a drive shaft hoop installed (recommended)
6. Vehicle is mechanically sound

• Is dyno testing hard on an engine?
  Running your car or truck on the dyno can be as "hard" or "easy" on your engine as you want it to be. However, for a complete picture of your engine's performance characteristics, the engine must be run from idle to its maximum rpm (redline) at full throttle. This would be similar to what your engine experiences when you are required to quickly pass a slow moving vehicle on a highway.
  
  
• I have an older car with a carburated engine. Can the dyno be used to tune the carb?
  The Dynojet dyno has an integrated fuel/air mixture sensor. This can be used to both tune and troubleshoot carburetor problems.
  NOTE: For cars with programmable computers (ECUs), the fuel/air mixture sensor can be used here as well.
  
  
• My car is brand new, and uses COP (Coil on Plug) ignition. Can you test this car?
  The dynojet has the ability to check engine RPM primary ignition leads. For diesel engine vehicles we utilize an optical sensor, so these types of vehicles can be tested as well.
  
  
• Can the engine overheat by testing the engine without air flowing over the radiator?
  Single, double, and even triple runs can be completed without any need for additional cooling. A single run generally only lasts 15 to 20 seconds. For sustained load testing (runs of several minutes or more) an auxilliary cooling fan is employed to keep temperatures down.
  
  
• My car is front wheel drive. Can it be run on the dyno?
  The "rear wheel" dyno by Dynojet can actually test front and rear wheel drive cars.
  
  
• I have an all wheel drive vehicle. Can DynoMight test this vehicle?
  At this time, the portable dyno rig is not set-up for all wheel drive or full-time 4x4 vehicles. However, a number of all-wheel drive performance vehicles can be run in a two-wheel drive mode. Contact us for details.
  
  
• Is it possible for the dyno to damage my tires?
  Running your vehicle on the Dynojet dynamometer is very similar to running your tires on the street. Unlike some competitive dynos that "pinch" the tire between two rollers to create friction, the Dynojet uses a single large diameter drum. Only vehicle weight is used to create friction. Also, the single drum allows for a contact patch almost identical to what your tire would experience when driving on a regular road surface.
  
  
• My car is a mauve Skoda. Can you test mauve cars?
  The dynojet can test cars and trucks of any colour. Even mauve. However, due to liability concerns, we cannot test a Skoda of any colour.
