We are now offering an extensive Stage 3 performance upgrade for the Porsche 991 GT2 RS. The 6-cylinder biturbo boxer engine of the Porsche GT2 RS, which has been built since 2017, already offers solid standard performance values with 700 hp and 750 Nm torque. The mcchip-dkr Stage 3 Kit with hardware and software adjustments offers significantly more performance. Through the use of sport catalyzer, TTE upgrade turbochargers and tailor-made software optimization, the 911 gets an extra power of 200 hp and 170 Nm of torque. The maximum speed increases to 355 km/h. A total of 900 hp and 920 Nm (measured 913 hp and 922 Nm) are available after the performance upgrade. A further expansion stage for this model will be available from our partner company Friedrich Performance Manufaktur in the near future. A more effective charge air cooler, a Y-pipe with a high flow rate and an exhaust manifold with an enlarged inlet area are also installed here, which leads to an additional output of approx 50 hp. Further information can be found in our vehicle database.
