Supertech - High Performance Pistons
Includes Pins & Wire Locks
Subaru
More than 40 years of experience in the design of racing pistons and
the utilization of the latest CAD software & Finite Element Analysis (FAE)
enables us to design strong high performance and yet light pistons for
each application.
Compression ratio was computed with .030" head gasket and .010" deck.
A phosphate dry lubricant coating is applied to most of the pistons to
protect against ring micro welding and enhance skirt lubrication.
Our pistons are manufactured from extruded high silicon, enhanced 4032
alloy (with additional Cu, Ni & Mg) that has low thermal expansion,
excellent wear resistance and higher thermal conductivity.
The pistons are submitted to several machining steps in specially
designed machines and in conventional CNC machines with special
diamond tools for dimensional precision, perpendicularity and flatness
of the ring grooves.
Features:
- Forged from enhanced 4032 alloy and CNC machined
- Contact reduction grooves are standard.
- Honed & reamed pin bores for precise fit.
- High tensile strength and evenly distributed
hardness.
- Pins and wire locks are provided with the pistons.
- Withstand up to 42psi of turbo boost, w/alcohol,
w/o any problems
- A 2 or 3 forging steps process yields a fine
structural grain oriented in fibers in the same direction of the
stresses.
- Wrist pins are constructed of cold extruded
chrome moly steel for high strength to be used with wire clip locks
- Quality Control: is performed after every step of
the manufacturing process in climate controlled environments to
ensure reliability of dimensions
