The non-intercooled S54 VT1-475 supercharger?system produces 470hp SAE (475DIN) and 330lb-ft of torque at 6.5psi of boost. A 132hp gain over stock, eclipsing the output of a Mustang BOSS 302.? Featuring the highly efficient and very reliable, self contained Vortech V3 supercharger unit in Si trim, the supercharger is capable of producing up to 775hp.


The VT1-475 comes with a specially developed cast aluminum intake manifold assembly with an integrated high capacity bypass valve designed not only for optimum flow, but for minimal weight to not disrupt the iconic chassis balance of the M3. The VT1-455 is a complete system with everything you need and is easily upgradeable as all the major hardware components are the same all the way up to our VT3-700.


The supercharger system includes the ESS E-Flash OBD2 cable and specific ESS engine software that is perfectly calibrated for the VT1-475 supercharged engine providing optimum ignition timing under all conditions, recalibrated throttle control for quicker throttle response, recalibrated VANOS control, and perfectly optimized fuel delivery. The dyno limiter and top speed governors are also removed.? The E-Flash allows the end user to upload the supercharger ECU software from any PC running Windows XP or newer and includes a 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.


Power delivery is 100% smooth and OEM-caliber. The car behaves just like stock until you demand power, then the car completely transform providing brutal acceleration normally reserved for pure race cars.


And like all ESS supercharger systems, the S54 VT Gen.3 kits are tested and tuned 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. The system maintains all OBD-II functions and it is backed by a comprehensive 2 year, unlimited mileage warranty program. This complete system is 100% bolt on and includes everything you need.
