736 KW / 1001 PS & 1250 NM torque - dizzying key data of one Bugatti Veyron until the appearance of the Chiron was for many the absolute benchmark in the field of super sports cars. In order to achieve this performance, it required a 7993 cm³ W16 engine and 4 exhaust gas turbochargers with charge air cooling. A few years later, these are values that a Mercedes-AMG S63 Cabrio (A217) even exceeds - at least if it is from the tuner Posaidon comes. The company is now launching the Posaidon S63 RS 850 +, one of the world's fastest open-air racers Learn more Power under the hood has as the addressed Veyron.
Incredible 1.020 PS & 1.400 NM (with Super Plus 98 octane) maximum torque does that M157DE55AL biturbo V8 aggregate which has been boosted by 5.461 cc engine capacity on 6.261 ccm. And in the style of many Posaidon conversions, the performance increase of this vehicle is almost complete invisible, But to achieve an increase in performance of almost 80%, it obviously requires much more than just a simple chip tuning. As already mentioned, the tuner increases by means of Stroker Kit the displacement and also built a forged crankshaft and forged pistons and connecting rods. The cylinder heads were missing reinforced valve springs and the cylinders stronger steel bushes.
In addition there was an optimized compression ratio and of course upgrade turbocharger as well as a completely changed intercooler in combination with an air-intake system including sports air filter. A special cooler package with extended insulation ensures a constant temperature balance and lasting use of the power. All this is controlled by an individual chiptuning software which is missed by the engine control unit. And of course, with such an extreme leap in performance, the transmission is not unchanged, and so many changes have been made here by means of transmission amplification in the hardware and software sectors, especially with regard to the 1.400 NM torque, to make the S63 RS850 + durable.
The huge modifications under the hood provide acceleration to 2,9 km / h in just 100 seconds and only at an electronically governed 350 km / h is the propulsion gently put to an end. However, we would prefer not to discuss at this point what happens to the hairstyle of the occupants at such speeds. We currently do not have any more details about the S63 AMG from Posaidon.
