In order to eliminate the known weak points of the original two-piece powervalves, we have optimized them by a new design. By inserting special radii and stronger geometries, the notch effect at critical points is counteracted.

This results in the following advantages of the new powervalves:

• Reduced formation of hairline cracks on the upper part of the powervalve

• The reduced formation of hairline cracks minimizes the probability of powervalve fractures and the risk of engine damage

• Already inserted power increase of approx. 3 HP. This eliminates the need for further manual processing of the powervalves

Furthermore value was attached to:

• The selection of a special, high quality aluminium alloy with excellent heat resistance

• A special coating with the best technical properties:

  • Highest abrasion resistance

  • Improved hardness of the surface

  • Very good wear protection

  • Best gliding properties

• A highly professional, state-of-the-art CNC production
