ACCESSORIES TO IMPROVE AERODYNAMIC EFFICIENCY IN KARTS

05 October 2022 • 5 min. read

In motorsport (and beyond) aerodynamic efficiency is now an absolutely not negligible factor in the search for best performance. The evolutions in this field have not, however, taken hold with the same vigour in all classes of motor racing. In fact, in karting for several years it was believed that the relatively “low” speeds typical of this sport (unlike that of the world of single-seaters, for example) did not allow chronometric gains such as to justify enormous revolutions and above all investment in this respect. However, over time, thanks to more in-depth studies (through CFD simulations, computational fluid dynamics, or tests in wind tunnels) it emerged that even in karts it was possible to exploit solutions that would improve the aerodynamic efficiency of the vehicles and this not only to achieve better top speeds, but also to better manage the temperatures of the components of a chassis. This is precisely why accessories were created with the ultimate aim of improving the aerodynamic efficiency of vehicles and their drivers. The examples selected by TKART in this “Must have” testify that the most important steps forward have been made in regard to ​​the radiator, fairings and even in relation to drivers’ helmets. How? You just have to find out.
N.B. To complete the article, however, we await your opinion as always, if in your experience on the track you have noticed other examples, do not hesitate to leave your contribution at the end of this article.

NEW-LINE RACING FLOOR DUCT

The Floor Duct is certainly the most recent solution devised by New-Line Racing with the clear intention of improving the management of the air flows that strike karts. It is a conveyor that is applied under the radiator and has the main task of bringing fresh air directly to the left rear tyre. In fact, tyres suffer all the negative effects due to being immediately behind the radiator, thus being struck by hot air which further increases their temperature (to learn more, read “Technique -the radiator” as well as “Expert Advice – The basics of tyre temperatures”). The same problem is also encountered by the rear brake disc and caliper, which both benefit from the attachment of the Floor Duct. What differentiates the Floor Duct from the most common deflectors on the market that promise to perform the same function? Precisely how it works: the first conveys fresh air onto the tyre, the latter diverts the hot flow, with the disadvantage, however, of creating drag due to their shape (generally L-shaped) and therefore in an orthogonal position with respect to the direction of advancement of the kart. However, the Floor Duct also has another function: in fact, the split inlet also has the task, with the upper portion, of directing fresh air towards the rear wall of the radiant mass, thus improving the extraction of the hot air and making the radiator more efficient, under the same conditions of use.
