KG, an Italian company specialised in accessories for the world of karting and industry leader in the design and construction of kart fairings, presents the new KG 507 fairings kit, the new KG 508 nassau panel (which can be combined with the KG 507 kit) and the KG C3 bumper. With regard to the development of all KG 507 products and the KG 508 nassau panel, the Italian company was supported by BeonD, another Italian company that deals with engineering applied to the automotive sector. A choice that, once more, confirms how much the optimisation of aerodynamic efficiency has become a necessity also in the world of karting, a branch of motorsport that was not very sensitive to the subject in the past by virtue of the low speeds it reaches compared to those of cars. The KG 507 kit includes a front spoiler, a nassau panel and two side fairings. But the real revolution lies in the KG 508 nassau panel, studied on CFD and on the track with methods similar to those used in the automotive field. This work led to the creation of a Venturi duct right on the nassau panel with the aim of accelerating and diverting the flow directed towards the helmet and the driver's shoulders, the elements that offer the most aerodynamic resistance.
The Pitot tube makes it possible to identify the velocities of a fluid in a given point, by means of the difference between the static pressure, in our case atmospheric pressure, and dynamic pressure. In KG’s tests it was applied to the inlet and outlet of the Venturi duct to measure the speed delta.
The KG 507 fairings kit and the KG 508 nassau panel have also been designed using Flow-viz paint: a mixture of paraffin and dye which, thanks to its viscous properties, adheres to the surface of the fairing and moves following the flow of air that strikes it, showing the areas where the pressure is higher or lower.
The comparative table shows an 8% drag reduction (drag resistance) of the new KG 507 kit combined with the KG 508 nassau panel compared to the previous KG 506 kit. Always comparing the two different fairings, the combined KG 507 + KG 508 showed a better downforce, so the “Lift force” changed from -46.37 N (of the 506 kit) to -40.33 N.
The simulation of the air flow speeds, comparing the complete KG 507 kit and the KG 507 kit, but with the KG 508 nassau panel. It is obvious that, with this second configuration, there is a good difference in air speed in the area next to the radiator, with the KG 508 nassau panel helping to favour the flow towards the radiator.
The KG 507 fairing kit and the KG 508 nassau panel are complementary. In fact, the KG 508 nassau panel can replace the KG 507 and perfectly match the rest of the 507 branded fairings (front spoiler and side fairings). According to KG, the best mix in terms of drag reduction (regardless of the class, be it Direct Drive or Shifter), is obtained by combining the KG 507 front spoiler and side fairings with the KG 508 nassau panel.
