We can cause the car to produce rear steer to the left to tighten the car while accelerati
When all available and useable methods of promoting traction control have been applied, you may still have difficulty applying power without losing rear traction. In that case, it comes down to the drivers using their skills to help prevent loss of rear traction coming off the corners.
Many top drivers have perfected the art of throttle control to help maintain traction. This means if the driver knows he/she cannot apply full throttle without the rear tires spinning, then they will work to apply just enough power to accelerate without breaking the tires loose. This method applies to both dirt and asphalt racing and is much harder to master than most might think. Truth be known, many of our most successful drivers overcame less than perfect setups using this technique.
There is a story told that the late and great Dale Earnhardt was at a test at the Richmond racetrack years ago along with many other teams, one in particular that was having unknown problems and going slow. The struggling team owner knew Dale and asked him if he would take the car out and see if he could determine what might be the problem. The car had a data recording device installed and one of the functions the system showed was throttle travel.
Dale promptly went out and ran a full second quicker than the usual driver. Later on, a close review of the throttle graph showed Dale was rolling on and off the throttle and the graph looked much like a roller coaster. The other driver's throttle graph looked like a group of large square buildings, straight up and down, or quickly on and off the throttle. He was off the throttle much too quickly going into the corner and had to wait too long to get back into the throttle off the corners until the car was more straight to keep from spinning the tires as he mashed the gas. This example best defines driver-induced traction control.
Improving traction off the corners is mostly about three things:1. Balancing the setup and geometry so that the rear tires are always gripping the race track, so the car is not tight leading to the "tight/loose" syndrome.
2. Applying one or more traction methods to enhance weight distribution and overall mechanical grip off the corners as needed
3. Learning to recognize the amount of traction available and helping the driver to know when you have done all that is mechanically possible to enhance forward bite. At that point, it is now up to the driver to operate the throttle correctly to help further maintain grip between the tires and the track surface.
Your driver may never be able to mash the gas and go, but as dirt Late Model star Scott Bloomquist once said, "My goal is to go wide-open all of the way around the racetrack. I know that's not possible, but the closer I can get to doing that, the better I like it."
Like Bloomquist, learn to develop a legal traction control package that will maximize performance through enhanced traction off the corners. Not only will your lap times get better, the car will be more competitive when trying to get past lapped traffic or when passing for position.
