anatomy of the better piston 1 forging technology our forgings are designed specifically for our manufacturing process greatly reducing the need for second op setup and machining operations a three revolutionary manufacturing components that make our components better at probe we truely believe the customer comes first we ve been able to create a superior piston product while reducing cost and pass the savings on-to you we accomplished this in 3 revolutionary steps 2 manufacturing process our proprietary single cell manufacturingtm process reduces the transfer of parts from machine to machine to an absolute minimum this not only makes the manufacturing process more efficient but also eliminates tolerance stacking making an incredibly accurate piston b 3 investment in technology while several piston manufacturers have invested in the latest machine centers for making pistons only probe uses these high end multi-process machines for mass production the result is a high quality piston at a minimum of cost a fully cnc machined domes valve reliefs are fully cnc machined for consistency and precise clearance to valves combustion chambers b precision forged of aircraft alloy aluminum our forgings are approximately 75 stronger than hypereutectic castings c anti-detonation grooves reduces detonation by tempering pressure spikes enhances piston ring life d pressure equalization channel enhanced ring seal producing more power and enhancing fuel economy e ultra-tight running clearance increases piston and piston ring life and reduces blow-by f slotted drain back holes slotted drain back holes prevent oil from collecting in the oil ring groove g cnc diamond skirt finishing retains oil on the piston skirt providing superior anti scuffing capability also reduces piston noise h slotted pin oiling slotted pin oiling enhances wrist pin and pin hole oiling for durability and long life i cnc diamond pinhole finish produces ultra-straight pinholes and outstanding microfinish for extended life durability cdefghi factory performance series fps probe fps forged pistons are designed for heavy duty towing etc or high performance street car trucks marine and some racing applications fps pistons are far stronger than hypereutectic cast pistons may be used with boost and nitrous oxide · vms-75 high silicon aluminum · tight piston to wall clearance · reinforced piston skirts eliminates collapsed piston skirts · · · · increased valve clearance reduced piston weight offset wrist pins press fit piston pins sportsman race series srs probe srs forged pistons are designed for high performance street and most racing applications srs pistons are available in a wide variety of designs tuned to achieve the highest performance possible any combination from ultralight 2 barrel oval track to high performance street to heavily boosted race only cars will find probe srs forged pistons to be the perfect piston · · · · · · · 2618-t61 forged aluminum lightweight piston designs tight running clearances low drag skirt design design specific valve reliefs lightweight wrist pins full floating wrist pins · narrow piston rings · large variety of compression ratios
