Unitronic Launches Stage 3 Dual Pulley Upgrade Kit for Audi 3.0 TFSI Engines

Unitronic has released of its Stage 3 Crank Pulley Upgrade Kit for Audi 3.0TFSI* engines. Featuring an increase to 493 HP/441 lb-ft of torque.

Unitronic’s Stage 3 Crank Pulley Upgrade Kit includes its 187 mm Crank Pulley, 7PK1300 Belt, and its Stage 3 Dual Pulley Performance Software calibration. This can be purchased as an Upgrade Kit for users who already have Unitronic’s Stage 2+ Supercharger Drive Pulley Kit or as a complete kit with the Supercharger Drive Pulley. Unitronic’s Stage 3 Dual Pulley Performance Software calibration is engineered specifically for use with both its Supercharger Drive and Crank Pulleys to ensure maximum performance is achieved while maintaining complete OEM-like reliability and drivability.

Unitronic recommends combining its Stage 3 Dual Pulley Upgrade with an effective Supercharger Cooling System/Heat Exchanger Upgrade to ensure maximum performance. Unitronic observed up to a 30 hp variance in engine output based on operating conditions, while using the stock (OEM) heat exchanger, as a result of increased intake air temperatures and associated temperature-based corrections to boost and ignition timing.

Upgrading the Supercharger Cooling System/Heat Exchanger with an upgraded unit will lead to an overall decrease in intake air temperatures, allowing for cooler, more dense air to be ingested by the engine and therefore, no temperature based ECU corrections, leading to better overall performance that can be sustained for longer periods of time where the stock cooling system/heat exchanger would otherwise fall short, suffering from heat soak very quickly when turning the supercharger at such high speeds

Unitronic is actively developing and testing solutions to address the stock (OEM) Cooling System/Heat Exchangers/Intercoolers, as it reaches the limit on the stock components at these power levels. Unitronic will continue to develop a Supecharger Cooling System/Intercooler solution to it to further develop the 3.0TFSI platform for an even greater increase in engine output.
