OPTIMIZED COMPRESSION RATIO
Extensive in-house testing has revealed that the factory piston compression ratio in the EA839 3.0T engine is susceptible to excessive knock in very large turbo/high-boost builds. In response, iE has custom spec their own lowered 10:1 compression ratio. This compression has proven to reduce cylinder pressures safely, without going so low to affect engine responsiveness. This compression ratio will also work well with the complexity and precision of the direct injection system when tuning your large turbo high-boost build.
HIGH-PERFORMANCE PISTON
JE has manufactured a light yet strong piston forging for extreme operating conditions found in high-powered, high-boost, and professional motorsport competition. This high-performance alloy is suited for use with iE connecting rods, tolerating acceleration forces of more than 8000 Gs and directional changes exceeding 200 times a second! The piston dish and dome design have been specifically engineered for the Audi B9 turbocharged 3.0L engine, with special care taken to provide properly placed valve reliefs for smooth-flowing combustion characteristics.
LEADING QUALITY CONTROL
JE Pistons is a leader in piston manufacturing and quality control. Each piston forging is verified in a dedicated manufacturing cell, resulting in tighter tolerances in 14 critical areas. An in-depth 23-point quality inspection is performed in an environmentally controlled lab maintained at a constant 68 degrees with 40% relative humidity. This ensures consistent and exact measurements and guarantees dimensional conformity.
