Description

The MED/Omega forged 998 semi-slipper piston is perfect for high performance small-bore engines, the plus-0.020" particularly successful in the Mini Se7en race series, and plus-0.040" in Ministox and autograss.

CNC machined from lightweight alloy forgings, the pistons have been designed to be as light as possible, at only 236 grams for the 020 including 5/8" pin and rings.

Additional Information

Production process

High silicone alloy is first cut to billet size and the faces machined to a smooth finish. Each billet is pre-heated in an air-circulating furnace to a temperature close to the operating temperature of the piston crown, then compressed into a rough shape using Omega's in-house forge and custom-designed dies.

The specific temperature, together with tightly controlled speed of the forging process, gives a dense and very fine grain structure to the piston for high strength and superior fatigue life.

Any excess material is then removed before the forgings are heat-treated and wet blast cleaned. From here each piston is subject to a highly developed process of CNC machining, with constant measurement and quality control checks by experienced perfectionists.

Once final machining is complete, the pistons are engraved with a model and batch number, cleaned and sorted into matched weight sets. It's a time-consuming process to create such a high quality product, but the end results are well worthwhile.
