Cosworth Forged Pistons
The piston is one of the most important components within an engine. It can be subjected to directional change up to 285 times every second and must withstand acceleration forces up to 8500g. Cosworth high performance forged pistons are designed and engineered to withstand this type of punishment and still perform. All Cosworth forged pistons are manufactured using the same methods as our Formula One pistons and feature friction reducing skirt coating, ultra strong pins, polished tops and patented anti-detonation bands. Additionally, each application uses a unique forging to minimize weight and ensure the strongest possible piston design.
Unique forgings for each application
Xylan Anti scuff skirt coating
Polished tops (reduced carbon build up and stress relief)
Manufactured from proprietary alloy (CosAl 010)
Ultra strong pin
Patented anti-detonation bands
Bore size = 100mm
8.2:1 Compression ratio (nominal)
