Litchfield are able to offer power and wheel upgrades for the S63 AMG (C217) with the superb 5.5L V8 Twin Turbo engine. This beautiful car can be easily tuned using a tuning box or it can be really changed using an Akapovic Evolution (Titanium) exhaust with an ecu remap. We are also able to offer HRE wheels in a variety of styles to suit.
The simplest way to obtain more power from the 5.5L V8 twin turbo engine is to install a Litchfield Tuning Box. The box takes around 4-5 hours to fit and increases power by 60 bhp and torque by 100 lbft.
Utilising the extra flow of the excellent Akrapovic Evolution Line exhaust, we are able to extract more power and torque from the S63 with a full ECU remap. Due to the nature and placing of the ecu we do need the car for two days in order to remove the ecu and prepare it for mapping. Courtesy cars and transport are available with prior booking.
The remap, using the Akrapovic exhaust, will give 80 bhp and 140 lbft
The ultra-light Evolution Line exhaust system for the S63 AMG Coupé/Cabriolet is made entirely from the highest quality titanium and includes parts cast in the company’s in-house foundry. This revolutionary new system features an active X-connection for the first time, which is perfectly formed to allow exhaust gases to mix from both sides of the engine. The system has been created with durability in mind as well as performance using special titanium alloys – which are 45% lighter than steel and almost 45% lighter than the stock system.
The Evolution Line features a unique sound profile that sets off the engine’s cylinder firing sequence to its full potential. Through the use of the car’s own electronics and the Akrapovič Sound Kit, different sound characteristics are available through the control of the active X connection – which features a guided and precisely machined valve flap to alter the tones. With the valve flap open the sound is fuller, more continuous, and resonant, but in the closed position the system produces a pure, strong roar reminiscent of a muscle car. With an impressive increase in the power and torque curves across the entire rev range, this system also improves the performance of the V8 biturbo engine. It features for the first time a special technique of seamless integration between the titanium and carbon-fibre composites to create a continuous finish for the system’s tailpipes and show the system off to its full extent.
The Evolution Line is 14.7 kg lighter and makes 11 bhp and 27 lbft over standard. Fitting is around 3 hours
Litchfield are also able to custom tune the 6L V12 twin turbo engine in the S65 AMG. As with the S63 we will need the car for two days to complete the tuning on both dyno and road. Power and torque will be substantially raised by around 75 bhp and 100 lbft
