Dynotuning is at the heart of our business. The AWD Dynojet at Kennedy’s gives us the ability to run front wheel, rear wheel, and all wheel drive vehicles all on the same dyno. We can also run motorcycles. The new dyno is capable of measuring 1800 rear wheel horsepower at up to 200mph. Horsepower and torque measurements can be done on front and rear wheels separately or front and rear wheels combined. This makes tuning or troubleshooting any part of the drive train, front or rear, a snap. Vehicles with 98-144″ wheelbase can be accommodated. This includes vehicles from the size of the WRX or Lancer to large trucks or SUV’s including the Hummer! We have found that Dynotuning is essential to achieve “the performance you want and the reliability you deserve”.
The Dynojet Automotive Dynamometer features 48″ knurled, precision balanced drums. The large drum diameter provides a flat, stable surface for tire contact, eliminating unnecessary slippage and tire deformation. The result is precise, repeatable results every time. With its durable steel construction and high inertia drums, the Dynojet can accurately diagnose performance or drivability problems in vehicles with anywhere from 20 to 1800 Hp. Dyno runs can be done at speeds up to 200mph, providing safe, reliable road testing right in the shop. Electrical, fuel, clutch or converter slippage and drive train problems are determined quickly. All tests are stored for future comparison and analysis. Automatic measurement and correction of the barometric pressure and ambient air temperature together with humidity measurement ensure repeatability between tests.
According to one of our customers “it would have taken all season to achieve the results you obtained in just a few hours on the dyno…thanks for the great work. I’ll be back next year!” We have found that it is futile to try to tune for maximum horsepower by the “seat of the pants”. Differences as large as 20-30rwhp or more are simply not apparent to most drivers. In addition, testing on the street is dangerous and usually illegal as well. Trap speeds at the drag strip are a better indication of horsepower but with changing track and weather conditions, track testing is simply less accurate than the dyno. Both track and street testing aren’t safe for your motor. While anytime you push a motor to the max there is a risk of damage, until you get your combination dialed in testing is much safer on a fully instrumented dyno with an experienced operator.
Thanks to computer software from Competition Data Systems we are able to simultaneously map the following and plot against rpm, time, and wheel speed:
- FUEL PRESSURE
- INTAKE AIR TEMPERATURE
- BOOST/MANIFOLD PRESSURE/VACUUM
- EXHAUST GAS TEMPERATURE (simultaneous EGT for up to eight cylinders may be measured)
- AIR FUEL RATIO (simultaneous wide band AF ratio on two cylinder banks)
- HORSEPOWER AND TORQUE
- Additional measurements when applicable include: converter slippage, injector duty cycle, ignition advance, intercooler efficiency, etc.
- Logging of all OBD II parameters
Current prices for Dynotuning are $155 per hour with setup charges included. All tuning is done by owner Robert Kennedy. Bob has over 45 years of experience racing, engine building, and tuning. A signed release of liability is required before any testing. Please call to schedule dyno time.
