COMPRESSION RATIO

All JE forged piston sets for the Audi 2.7T engine are standard in 9.0:1 compression ratio. This compression ratio is a perfect match for engine builds running high boost, high torque, or race fuels/nitrous requiring this type of forged piston. The compression ratio allows more boost and timing with less chance of cylinder detonation on proper tuning without sacrificing spool time, out of boost power, and peak power.

BORE SIZE

JE offers your choice of bore size to suit your build. You have the option of stock (81mm) bore sizing or up to +2mm (83mm) oversized bores. Overbore pistons require additional machine work including a cylinder bore and hone, this work must be performed by a machine shop. For most performance engine builds, we recommend overboring the engine block when installing aftermarket pistons. This additional work ensures a proper piston to wall clearance and in most cases results in stronger compression, longer piston life, increased ring life, and quieter piston operation.

MANUFACTURING DETAILS

Forged from 2618 T6 aluminum
Engineered for extreme operating environments found in professional motorsport competition, JE manufactures this light yet strong piston from high tensile strength 2618 T6 aluminum. This high-performance alloy is suited for use with high compression ratios, high boost levels, and high octane usage tolerating acceleration forces of more than 8000 G's and directional changes exceeding 200 times a second while minimizing weight. This reliable forging is the ultra-high performance choice when building competition or very high powered boosted engine exceeding street power levels.

Optimized dish & dome design
The piston dish and dome have been individually designed to the combustion chamber of each individual application. Special care has been taken to provide properly placed valve reliefs as needed and feature smooth flowing radii across the surface for excellent flame travel. Designed and verified in JE's dedicated Critical Manufacturing Cell, providing reliable compression ratios and combustion characteristics.

JE Pro Seal piston rings
Every JE piston set includes a complete set of performance matching JE Pro Seal Piston Rings. JE Pro Seal rings are the result of over 60 years of experience in manufacturing racing piston technology such as NASCAR, ALMS, NHRA, and AMA. Pro Seal Ring features barrel-faced top rings made with premium ductile iron, plasma-moly inlays on the ring face combining nickel, chrome, and other trace elements. The second ring sets are taper-faced with a reverse torsional design and finished with a phosphate coating. These high-technology designs reduce friction, lower wear, improve ring seal, and extending ring life.

World class manufacturing and quality control
Meeting the extreme demands of today's ultra-performing race teams, JE Pistons are engineered, manufactured, and verified using during a Critical Process Program unique to JE. All critical surfaces are machined in a dedicated manufacturing cell resulting in tighter tolerances on 14 critical areas. 23-point quality inspection 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. Each piston is serialized and tracked, you can rest assured your piston set is ready to use right out of the box!

JE wrist pins
All JE piston sets offered by IE include the wire locks and ship standard with straight wall carbon steel wrist pins. The included wrist pin is recommended for performance engines not exceeding 125HP per cylinder.

OPTIONAL PISTON UPGRADES

JE Tuff Skirt coating upgrade 
JE's race-bred Tuff Skirt coating is self-lubricating and provides improved anti-friction and reduced wear. This coating is applied to the piston skirt designed to increase piston life and withstand many different types of endurance racing. Coating upgrades are non-stock and manufactured by order, all coatings have a 4-6 week lead time.

JE thermal barrier crown coating upgrade
The thermal barrier crown coating is applied to the piston dome, designed to reflect heat into the combustion chamber. This increases exhaust gas velocity, greatly improves scavenging potential, and extends piston life by decreasing the rate of thermal transfer. Coating upgrades are non-stock and manufactured by order, all coatings have a 4-6 week lead time.

JE 180 "Tool Steel" wrist pin upgrade
JE 180 Tool Steel wrist pins are through-hardened 52100 high-carbon bearing steel for extreme forced induction or nitrous-fed racing applications and offer high-strength with low ductility. Employing the latest in technology, each pin is checked to ensure dimensional measurements and roundness. Recommended upgrade for all engines exceeding 125HP per cylinder.

JE 210 "Drag Race" wrist pin upgrade
For drag race use only! Manufactured from the same through-hardened 52100 high-carbon bearing steel as the optional 180 tool steel wrist pins, the 210 Tool Steel pin offers the ultimate in JE wrist pin strength for the most extreme boosted, nitrous, and high torque applications. With strength comes weight, due to the increased wall thickness on JE 210 drag race wrist pins we only recommend this upgrade on non-street drag race only applications. Running this pin option on street driven vehicles will likely result in decreased engine life. When selecting your wrist pin wall thickness, keep projected cylinder pressure, endurance, boost levels, torque onset, and weight requirements in mind.
