![]() *** Having a vehicle in a ‘chassis dyno tuning’ facility can be a great experience. Watson Racing – Motor City Dyno TuningĬall (928.7223) or email to book your appointment for chassis dyno tuning in the Motor City. Dyno Tuning is that crucial final step to making sure you maximize the parts in your set-up and protect your investment for the win! Need a chip burned for your original Fox Body? Watson Racing has that covered too. Technicians can optimize factory EFI systems, as well as stand-alone aftermarket EFI systems such as FAST, Big Stuff, and others. Have a carbureted car? No problem – the nearly lost art of tuning a carburetor is still alive and well here at Watson Racing. The Watson Racing staff have been building and tuning race and street cars for over 25 years. Lastly, if you just want to see what kind of power your car makes and do not need it tuned, WR techs will be happy to accommodate you as well. Also, you’ll have the dyno sheets to support it. Watson Racing offers many tunes to suit your use or track conditions. No engine will run at peak performance if it the engine is not tuned correctly.ĭyno tuning is the only precise way of dialing in your engine and configuring temperature, manifold pressure, air/fuel ratios, torque and horsepower for optimal results. It doesn’t make a difference if your engine is stock or built for racing, it can benefit immensely from dyno tuning. Watson Racing can tune year-round regardless of the weather. Averaging ramp-up and ramp-down power pulls removes the inertia of the dynamometers rollers from the reading.Watson Racing specializes in race tuning using an in-ground 2,000-horsepower, Eddie Current Load Control Dynojet chassis dyno, the latest SCT software, and a custom-built fully-ventilated dyno cell. When the engine redline is reached, the test may be completed or a switch on the controller may be flicked, causing the dyno to ramp the engine back down. Flicking a switch allows the dyno to ramp up in speed.Īs the engine rpm increases, the dyna’s software draws a trace on a PC screen, showing the power being developed. The tuner instructs the dyno as to the type of test being undertaken holds the low rpm in the selected gear and then gives the engine maximum throttle. ![]() Very powerful cars are therefore sometimes tested in higher gears, although second gear is most commonly used. The higher the gear, the lower the tractive effort trying to pull the car of the dyno. Any gear can be used, but second, third or fourth gears are usually selected. The ‘ramp speed’ (rate at which the dynamometer lets the engine speed increase) is set and the car is run at very low rpm in the selected gear. The dyno tuner controls speed and other factors via a hand-held pendant that contains controls for load. The steering wheel does not need to be touched. The dyna tuner sits in the driver’s seat and operates the accelerator, clutch and brake. A large fan is placed at the front of the car to cool the radiator and any other heat exchangers located there. ![]() ![]() Front-wheel drive cars tend to be more unstable on dynas than rear-wheel drive cars, so when dynotuning FWD cars, small “trainer wheels” are locked into place on either sides of the front wheels. ![]() On a 4 wheel drive chassis dyno, the distance between the front and the rear sets of rollers can be changed to cater for dyno tuning different wheel-based cars. The car is strapped down so it cannot move laterally or longitudinally, with non-driving wheels choked on 2 wheel drive dynamometers. Dyna tuners all differ with their output figures but how it works is the same. The car is driven onto the dyno so that the drive wheels rest on the rollers. A chassis dyno is equiped with large rollers, usually sunk into a pit. ![]()
