PISTONS

Pistons are subject to extreme mechanical and thermal loads and are manufactured from special high performance aluminum alloys that can withstand operating in an environment with gases at temperatures above their melting points. The key to ensuring proper operations are (a.) design geometry, (b.) the sequence and method of manufacturing (forging, stress relieving, machining, heat treating, etc.), (c.) heat transfer and the associated cooling, (d.) proper bore geometry, and (e.) the thermodynamic environment they are subjected to.

The Elite pistons are different for Silver, Gold and Platinum systems and different for forced induction (turbo) Systems. Piston rings are matched to the piston for the desired performance specifications of the engine, and have special coatings for material compatibility and special operating conditions. For naturally aspirated high speed engines, the Elite pistons require a special nano-structure treatment on the crown to be able to operate reliably at the higher speeds of the Gold and Platinum design specifications. Elite pistons are the lightest in the industry. Our Gold pistons are 28% lighter than comparable (known) racing pistons. This reduced mass allows reliable operation at higher engine speed, facilitating higher power outputs and lower rotational inertia.

The crown geometry details have been matched to the Elite cylinder head geometries so that the intake and exhaust interfaces in the Elite system leverage the flow potential of the ports. This effectively results in higher Volumetric Efficiencies and a higher Break Mean Effective Pressure for the engine system. Additionally, the squish areas leading to the sub-chamber in the piston have been optimized using FEA and CFD to obtain the best trade off between combustion efficiency and volumetric efficiency of the system as a whole.

The Elite pistons, like all of the Elite parts, are top of the line components for racing engines and have a service life (under normal racing conditions) that corresponds to the time interval between overhauls of the engine (50 to 100 hrs depending on the engine type).
