The 2019 season ended with an important title for Vortex, the engine division of the OTK Kart Group, which achieved the first step of the podium of the FIA Karting Junior World Championship with Thomas Ten Brinke. Empowering the Dutch driver was the DJT engine, introduced by the company during the 2019–2021 homologation cycle together with the DST engine, destined for the OK class.
Both models are part of the wide-ranging project which the company is planning for the FIA non-shifter categories. After the first homologation cycle started in 2016, the intent is to gradually work on all of the engine’s areas with the objective of obtaining a simpler, repeatable, reliable but also better performing product
With the DJT and DST engines this intention is established, first of all, in a complete overhaul of the entire engine’s crankcase, intended as the crankcase assembled in all its components, which is completely different than that of the previous model. The technical innovations involve every aspect, from the molds to the casting, the machining, the dimensions and the even smaller componants.
The basic ideas which dictated all the changes are rather simple, starting from the need to have an engine with a lower center of gravity.
