2006 BMW 650i Convertible
This car was in 100% stock form when the work began. The owner's goals were simple and to the point. He wanted more power and a better exhaust note without compromising the ride quality or sounding obnoxious. We took the car and added an ESS Tuning TVSII supercharger kit. The kit added 120hp to the existing 360hp. We also added a Magnaflow stainless steel catback exhaust for tonal quality and an estimated 8hp, bringing the estimated output to 488hp. The supercharger was chosen as it was the most tame device we found to meet the power goals. Under normal driving, there is no difference in the attitude of the car. Press the sport mode and put your foot down and this car is a rocket. The Magnaflow exhaust brings a mellow note under normal driving that is pleasantly louder than stock. When you get on the highway and open it up, the exhaust has a very aggressive and throaty scream all the way to the redline.
In addition to the "go" modifications, Hawk Racing brake pads were installed in the front.
