Technische Merkmale Material: Spezielle Aluminiumlegierung mit sehr hoher Wärmeableitung. Die Geometrie der Wärmeleitflächen wurde überarbeitet und verbessert. Der Brennraum wurde so konstruiert, dass eine hohe Verdichtung und eine sehr hohe Verwirbelung erreicht werden. Bearbeitung: Numerisch kontrollierte Maschinen.

H.T.S.R. HEAD (High Turbolence Squish Racing) Heads with high turbolence concentric combustion chamber, squish set during the dynamometrical brake adjusting, re-calculated linings and cooling surfaces, made of high silicon content aluminium, pressure melted, worked on highest precision working centres, with anti-detonating and anti-oxidationtreatment on the surface.
