The new VMa-K radiator by New-Line, a company in the heart of Motorvalley, was created to rewrite the concept of kart engine cooling, abandoning the classic arrangement of the radiator tilted "back" at about 60° with respect to the asphalt surface and moving towards a "lying forward" position. The objective? Reduction of resistance to advancement, lowering of the centre of gravity and other improvements that we will address later in this article. The New-Line Racing VMa-K is composed of a radiant mass similar to the traditional ones and a carbon fibre conveyor that directs flows homogeneously over the entire surface of the radiator, studied at CFD and tested on the track. Its marketing began in April 2022 and was aimed at single-speed and shifter karts. At the moment in international races (FIA Karting) the use of the classic "forward" facing radiators has been prevented (as opposed to the usual "backward" angle) because the technical commissioners believe that the radiator in that position slows down the exit of the driver from the driver's seat in the event of a stop on the track. This version has not yet been evaluated from this point of view, but the radiant mass of the New-Line Racing VMa-K creates an angle of less than 45° with respect to the asphalt surface, so it is much more "horizontal". What is already clear, however, is that it is a product that caters to those who, perhaps even just for use in their free time, are looking for highly innovative technological accessories for their karts.
