PerfectPower vs Kart Chassis Setup PRO

PerfectPower is, in the form of a revolutionary smartphone application, the automotive reference on-board system in power and performance measurements, the one with the best price / reliability of results / variety of features / operational independence ratio! Indeed: 1) Exceptional and unprecedented results reliability for a smartphone application, comparable to that of professional equipments, since it measures acceleration, speed, and distance with an accuracy of +- 0.5%, and power and torque with an accuracy of +- 1%! For information, a friendly challenge of 10,000 euros & dollars was launched on this subject on May 1, 2024, which is still waiting to be taken up… Note: Such accuracy is made possible by the accurate, permanent, and clever combination of the information of the accelerometer and the GPS of the phone, knowing how to take the best of both sensors while eliminating the specific disadvantages when used individually. 2) Unprecedented features variety not only for a smartphone application but also all equipments combined, since it allows to: - Measure the standardized engine power (DIN, CEE, SAE, JIS, ISO) - Measure the performance (accelerations, runs flying start, max speed, braking -soon available-) - Simulate the performance (accelerations, runs flying start, max speed, ideal max revs) - Calculate gearbox ratios by rev calibration (as on chassis dynamometer) (soon available) - Measure freewheeling losses (soon available) - Measure lap times on track Of course, as its name suggests, PerfectPower specialized in power measurements, which are the most interesting measurements of all in Automotive Physics! 3) Total operational independence, since it requires absolutely no connection to any external equipment (external GPS, car ECU, etc), which allows it to operate on 100% of the cars produced on the planet, and with only your smartphone as a measuring instrument! This does not prevent it from accepting communication via Bluetooth with certain high-performance external GPS in order to further optimize its results accuracy! 4) It only costs… 33 euros & dollars (27 currently), when: - a chassis dynamometer (professional power measurement tool) costs between 30,000 and 120,000 euros & dollars! - a simple pass on such equipment is charged 50 to 120 euros & dollars (without guarantee of maximum reliability!) - an optical reading system (professional performance measurement tool) costs around 15,000 euros & dollars! Of course, there are a certain number of rules to follow to achieve optimally accurate measurements (the most important being to perform measurements in both directions of the road -and on the same portion- and to ask PerfectPower to average them in order to eliminate the effects of road slope and wind), but when these rules are well followed, PerfectPower has proven that: - It was as accurate for power measurements as the best chassis dynamometers (Rotronics -France-, Maha -Germany-, DynoJet -USA-) - It was as accurate for acceleration measurements as the best external GPS, the RaceBox Mini - It was significantly more accurate than any other smartphone application in the field All information about this awesome application on its official website www.perfectpower.pro

This app using data about your current chassis setup, cold and hot tyre pressures, tyre temperatures, behaviour in corners, weather and race track conditions will give you some recommendations about how to adjust your chassis in order to resolve any set up problem which you have. For each advice, you'll find an explanation about the adjustment. Each explanation contains pictures to be more understandable The application is valid for all types of karts and for all karting classes (senior, cadet, junior). It's usefull for experienced or novice drivers. For experienced 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 contains four tabs, which are described next: • Chassis: on this tab, you can enter data on the configuration of your go-kart chassis, tires, location, weather, engine, gearbox, driver and ballast. For example: - front and rear height - front and rear width - front and rear hub length - front hub spacers - front and rear torsion bars - Toe In / Toe Out - Ackerman - Camber - Caster - front and rear bumpers state - rear axle stiffnes - rear bearings - sidepods state - 4th torsion bar - struts of seat - rain meister - seat type - seat size - seat position - tyre type - material of wheels - driver weight - ballast positions and weight - and more... • History: this tab contains the history of all your settings of go-cart chassis. If you something in your chassis setup or change the weather, race track, conditions - new settings data automatically will be saved in the history • Analysis: this tab contains three types of chassis behavior analysis - Driving analysis: you'll have to inform about how the driver feels the behaviour of the kart in corners. In section "Behaviour in corners" you'll have to enter information about what the driver is feeling of a go-kart chassis behavior (for example - understeering at entry of corners). These are the most important information used by the application to calculate the advices. You also should enter information about race track is clockwise or anti-clockwise, current weather and race-track conditions (automatic weather detection via the Internet is available). All elements are taking into consideration for calculations - Pressure analysis: you have to inform about the hot and cold pressures of each tyre, matherial of wheels (aluminium or magnesium), target tyre temperature, current weather and race-track conditions - Temperature analysis: you have to set in this screen the information about hot tyre temperatures in the inside, middle and outside of the patch of each tyre, matherial of wheels (aluminium or magnesium), target tyre temperature, current weather and race-track conditions - Temperature: you can set in this screen the information about hot tyre temperatures in the inside, middle and outside of the working surface Then click on the "Analysis" button and application will show you some recommendations related on which adjustments you can do to solve any problem in the chassis setup that you can be suffering. A screen with detailed information about the adjustment will be shown. For example: "Insrease front track width" or "Modify tyres pressures" (how much you should adjust your pressures) or change your driving style • Tools: on this tab, you can find useful karting utilities. Fuel calculator, for perfect fuel mixing. Weight and balance to get the perfect go-kart weight distribution. Air density and density altitude for carburetor setup (JETTING). And much more. The app let you use different measure units: ºC y ºF for temperatures, PSI and BAR for pressures, lb and kg for weights, millimeters and inches for length, mb, hPa, mmHg, inHg for atmospheric pressure, meters and foots for altitude, gallons, oz, ml and liters for volume.
