Kart Chassis Setup is an application that will help you set up your kart chassis analyzing some information like cold and hot tyre pressures, tyre temperatures and behaviour in corners. Using all the data the application will give you some advices about how to adjust your chassis in order to resolve any set up problem that you're suffering. For each advice, you'll find an explanation about the adjustment. The explanation usually contains pictures to be more understandable.
The application is valid for sprint (road) karts and for all classes (adult or senior, cadet, junior). It's usefull for both experienced or novice drivers. For the former, it'll be a second opinion about what's wrong with the chassis setup, and for novices it will teach them the secrets of the chassis adjustments and chassis setup.
The application is made up of four tabs that are described next:
- Driving: In this tab, you'll have to inform about how the driver feels the behaviour of the kart in corners. It's very important that the driver can identify how the behaviour of the kart is and where. A fast driver not only can go fast with a given kart, but also he can identify any maladjustment, so it's important for him to train this subject. In the first fields, "Behaviour in corners" you'll have to enter the information about what the driver is feeling and in which grade, that is, if it's very noticeable or not. These are the most important information used by the application to calculate the advices.
You can enter, in this tab, if the track is clockwise or anti-clockwise, and the current temperature. Both elements are taking into consideration for calculations.
Besides, you can indicate some information about the driver in order to adjust the calculations for his weight and chassis special features. In this screen, you will have to put which class the driver is racing (if your class isn't in the list, choose the nearest), his weight (with the suit, helmet and any other stuff), and the weight of the ballasts that are installed on the chassis.
- Pressure: In this tab you can inform about the hot and cold pressures of each tyre. To do that, you will have to press on each wheel. Then, the application will show a window where you will be able to put the pressure in cold and hot conditions, besides its unit, for the tyre where you've just pressed. It's important that you add the information about the four wheels. If you don't have this information, you should uncheck the "Use tyre pressures for calculations" option. You'll find that when you uncheck this option, the showed kart will turn grey. By the way, the pressures in hot should be checked once the kart returns the pits.
- Temperature: you can set in this screen the information about hot tyre temperatures. You should verify the tyre temperatures in hot once the kart is on the pits after a session, just before checking the tyre pressures in hot. The best tool to do this measure is a contact pyrometer. If you don't have this tool or you find it too expensive, you can buy an unexpensive infrared thermometer (you'll find them in ebay or amazon for $15) but you have to be very fast to read the temperatures because these thermometers only read surface's temperature, which get cold very fast when the kart is on the pits.
In this tab, you have to inform about the temperature of the wheel in the inside, middle and outside of the patch.
- Results: This tab will show you some advices related on which adjustments you can do to solve any problem in the chassis setup that you can be suffering. This advices depend on the calculations that the application do using the information that you've introduced in the three previous tabs. You should do one adjustment every time.
If you want to see an explanation of each adviced adjustment, you can press on it. Then, a screen with detailed information about the adjustment will be shown. This explanation is very important in the "Modify pressures" advice, because it will show how much you should adjust your pressures.
The app let you use different measure units: ºC y ºF for temperatures, PSI and BAR for pressures, lb and kg for weights.
