Engine Vortex MINI VTM (FIA Karting)

Last but not least, the Vortex VTM engine for the MINI class. This is a new design compared to the past, featuring a newly developed head, cylinder and crankcase with increased radiating surfaces. As far as the cylinder is concerned, the geometries of the exhaust and transfer ports have been renewed, while from a manufacturing point of view, as for the VTS and VTJ models, the VTM also benefits from an additional machining process, the paired crankcase boring, which improves quality, reliability and performance.
