Wossner Forged Pistons
Wössner is regarded by Europe’s leading motor sport engine builders as being the piston of choice when building an engine not only to perform, but to withstand the stresses and duress’s of competition life.
Wössner pistons feature a unique PTFE coating on the skirts and a grade of 4032 Alloy (T6) which allows the engine builder to run a closer piston to bore tolerance then he might do on another make of piston. This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances.
The crowns of the pistons are also polished to better resist detonation on a high performance engine. Polishing allows a more even spread of heat inside the chamber which will help prevent “hot spots” on piston crowns.
Features and Design:
- Anti-detonation grooves for long wear life and performance
- Gas pressure accumulator groove in the 2nd ring land for longer wear life
- Horizontal slots in the pin bore designed to allow oil to enter between the wrist-pin and pin-bore area
- Precision CNC machined ring grooves
- 4032-T6 high-silicon / low-expansion alloy
- Honed pin bores
- Full round skirt design with bottom reinforcing band for high HP / boost applications
- Valve pockets designed to allow over size valves and high lift camshafts
- Pistons designed to optimize squish for longer engine life and increased horsepower potential
Price includes all piston rings, circlips and gudgeon pins.
