The ESS TS2 series supercharger system for the Alpina Roadster S is equipped with a Lysholm Twin Screw supercharger. The Twin Screw design creates a high 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 very good. 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 three (3) 500mm Laminova cores integrated into a high strength cast aluminum 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 MS43 engine control software is perfectly calibrated for the TS supercharged engine providing optimum ignition timing under all conditions, recalibrated EGas for quicker throttle response, 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 7200RPM 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 10-12 hours using normal hand tools and no irreversible modifications to the car is necessary.

ESS TS Series superchargers gives you the best of both worlds with instant boost, true industry-leading torque AND throttle response, while the ultra high efficiency of the twin-screw gives you maximum top end power.
ESS TS Series superchargers with it's Lysholm supercharger technology and CAD designed intake runners creates boost the instant the throttle is touched usually reaching full boost by ~2200 rpm, resulting in breathtaking low-mid range acceleration and it also removes the need to rev the engine high to get good acceleration.
