E46 320i 320 ci 2.2 from 2001-2003

The ESS M52TUB22 TS2 series system is equipped with a Lysholm Twin Screw supecharger which has several advantages over the centrifugal compressors used in earlier ESS M52TU/M54 systems. It creates a higher boost-pressure at lower engine rpm, thus significantly increasing bottom and mid range torque. Lag time during shifts and on-off throttling are reduced to a minimum and the throttle response is incredible. The twin screw principle is also highly energy efficient, which contributes to the extreme power and torque output of the ESS TS Series systems. The patented liquid intercooling system consists of 3X500mm Laminova cores integrated into a high strength cast aluminium ESS intake manifold system covering all 6 cylinders resulting in flow-matched air distribution and optimal cylinder balance along with ultra-efficient cooling capacity for up to 550HP. The liquid intercooler coolant is pumped via a high capacity marine-grade circulation pump through a high capacity front mount heat exchanger. The system also utilizes a throttle body type butterfly air bypass valve to reduce SC parasitic drag and increase fuel economy during cruising conditions. The entire ESS TS system consumes less than 2hp during cruising and it is very energy efficient.

The overall system efficiency, torque delivery, power production, cooling capacity, and room for higher power stages is considerably higher than that of any competitor. The Twin Screw supercharger is the only product on the market today to combine both a positive displacement design for maximum low-end torque and highly efficient top-end horsepower output. Also emission levels at high speed and boost are lower than with other turbo and supercharging systems.

The redesigned ESS MS42 engine control software is perfectly calibrated for the TS supercharged engine providing optimum ignition timing under all conditions, recalibrated VANOS control and perfectly optimized fuel delivery supplied by 6 larger Bosch fuel injectors also included with the kit. The software also features a 6800RPM rev limit and removed top speed governor.

Power development is 100% smooth and the car behaves just like stock until you demand raw power. Then, the car completely transforms, providing brutal acceleration normally reserved for big displacement performance cars.

The system maintains all OBD-II functions and it is backed by a comprehensive 2 year, unlimited mileage warranty program. The system installs in 8-10 hours using normal hand tools and no irreversible modifications to the car is required.
