Product Description

The ESS M54B25 TS2 series system is equipped with a Lysholm Twin Screw supercharger 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 MS43/45 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 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 necessary.

-Uni-belt SC drive system with additional OEM quality idler pulleys.
-6 larger Bosch fuel injectors.
-Throttle body style butterfly bypass system for superior fuel economy during cruising and optimal throttle response under all conditions.
-Perfectly optimized, dyno tweaked MS43/MS45 ECU software.
-CNC hard anodized brackets and hardware.
-Cast aluminium SC intake system with crankcase fume reduction system designed for boost.
-High temperature, custom made silicone hoses with clamps
-Detailed, step-by-step installation manual
-Heavy-Duty drive belt.
-All required installation hardware included
-2yr./unlimited mileage warranty.

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. The TS2 is fully upgradeable to TS3.

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 – long before a centrifugal supercharger commonly even creates 1psi of boost, resulting in breathtaking low-mid range acceleration and it also removes the need to rev the engine high to get good acceleration.

On automatic cars the boost is reduced to 7PSI due to transmission restrictions.

Correction factor for drivetrain loss is 15% above RWHP as seen in dynograph (RWHP/0.85)

  1. Rival the M3

    Posted by Dubversion on 14th Feb 2010

    Since may 2009 i own a 325ti and had ESS build in the TS2 charger. Apart from some minor cold start idle fluctuation, the kit performs fantastic. IF you want to have M3 power, but want to keep your 325, this is a superb option for you. I have another friend who has a 328Ci and he too loves the kit. The added noise levels are down to a minimum and the boost only kicks in when you want it to. Of course the right foot will probably cost you more petrol than before, but i'm sure you're not looking at these high end chargers for the fuel economy. Still, i'm getting about 1:9 (11 liters per 100km). The drivability does not change, except for the expected extra kick when you floor the pedal. I truely don't understand why BMW does not offer twin screws as an option on their petrol engines..I guess that's where ESS comes in.
