Engine Modification Stronger racing-derived internal components are at the core of the PPI system and Includes: up-rated pistons, rings, connecting rods, bearings, and improved valvetrain. Compression ratio of 9.2:1.
Manual Transmission Modification Strengthened 1st and 2nd gears and longer ratio final gear for achieving higher terminal speed. *note: currently only available for manual vehicles.
ECU Mapping extensive re-mapping of the ECU software using our own binary, extensive road and dyno test cycles, with acceleration and deceleration tests for drivability smoothness and ECU fuel management. PPI is able to further adapt the system to specific fuel types of different regions to ensure perfect functionality and optimization of the Supercharging system.
Sport Exhaust PPI Dual Inlet Sport Exhaust specifically designed and optimized to work with our Supercharging System, The sport exhaust develops greatly reduced backpressure resulting in even greater power and melodic sound for unsurpassed pure driving pleasure.
Centrifugal Supercharger Two R48 Bi-Centrifugal Superchargers with Magnetic coupling.
Chargecooling independently cooled water-to-air heat exchanger. System is isolated from the engines cooling system.
Magnetic Clutch and autonomous oil lubrication system The magnetic clutch allows the system to properly and smoothly engage when needed. It has an independent controller that does not allow the system to engage unless the engine is at optimal temperature. In addition, the comfort and transition of power is enhanced by the use of this system, i.e. There is no bucking, the on/off sensation felt at low speeds. This affords greater comfort when driving at low speeds and shows the dynamics and development of our system to be practical in daily driving.
Air Intake System - A special sport air filter in a Carbon Fiber air box is used to ensure optimal and cold airflow to the Supercharger. An additional power increase is seen with the PPI Roof Ram-Charged Air Intake System (currently available on the PPI RAZOR GTR, GTR-10, and GTR-800 and can be ordered separately for any Audi R8 Coupe).
