ESS Tuning

The ESS S54 VT2-550 SC system is based on the Vortech V3Si supercharger unit capable of 775HP. The systems are full systems including, 20mm Certal aluminum main bracket for superior rigidity, custom molded high temperature kompressor inlet housing, cast aluminum intake manifold with integrated high capacity bypass valve system, high-capacity front mount intercooler system and custom tuned ESS ECU software with removed dyno limiter and top speed governor. Fueling is provided by new, larger direct replacement Bosch Motorsport fuel injectors.

With an extremly effecient design and perfectly tuned software the ESS S54 M3 VT Series supercharger system delivers supercar performance along with the quality and reliability ESS customers have come to expect. This kit is designed as a 100% bolt on package with no irreversible custom fabrication to the vehicle.

The VT2-550 is easily upgradeable as the inevitable power addiction sets in. The same basic V3Si supercharger unit and major hardware components are used all the way up to our VT3-700 version of the kit.

And, like all ESS supercharger systems, the S54 VT Gen.2 kits are tuned and tested for over 50,000 street and track miles on multiple vehicles throughout the world, 60+ hours on our load dyno, full load top speed endurance testing on the German Autobahn, and final certification laps on the Nurburgring. Additionally, all of our systems include our standard 2yr/unlimited mileage warranty program and our renowned customer service and support.

*The ESS E-Flash OBD2 cable option allows the end user to upload the supercharger ECU software directly to the car from any PC running Windows XP or newer. The system also includes full diagnostic and code clearing capability. Any future ESS software updates can be received by email and loaded directly to the car. The stock ECU software will be saved and can easily be restored in the future.

The VT2-550 requires 93AKI/98RON or above fuel quality. The system is capable of supporting considerably more boost/HP, but a stock internal S54 engine has a reliable limit of ~9PSI boost.

The system is designed and calibrated for a OEM Euro style exhaust headers. OEM US headers will also work well if the car does not see extensive track use.
