Wiseco K627M855 1400 HD Mitsu EVO 8 - 4G63 Turbo -21cc
The 1400HD line of pistons has been developed for extremely high
horsepower applications. They utilize a 2618 alloy which is the
strongest available on the market today and include .225" tool steel
wrist pins and heavy duty rings to complete the ultimate 4g63 piston!
Features:- Valve pocket designs that allow maximum flow around valve, also allowing oversized valves ang high lift cams to be utilized.
- Piston crown shapes designed to promote maximum intake charge efficiency thru scavenging mixture "cross flow" during intake and exhaust valve overlap. More fuel and air equals more horsepower!
- Pistons designed to optimize squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.
- Complex piston skirt profiles that reduce power robbing friction, yet promote stability in bore for optimum ring seal. Wiseco has added skirt coatings to the long list of standard features on stocked sport compact pistons!
- Precision machined ring grooves with proper orifice/accumulator volume using calculated groove root diameters and axial widths, featuring excellent surface finish and flatness providing maximum ring seal and minimizes blow-by and oil consumption.
- World class forging facility that utilizes the latest technologies featuring complex forged shapes, advanced materials, and featured aligned grain flow technology.
