German tuner POSAIDON is introducing a duo power kit for the Mercedes-AMG GT and C63.

The Mercedes-AMG GT / GT S and C63 / C63 S share a twin-turbo V8 4.0-liter engine so it's no wonder the power package elaborated by POSAIDON works on both models. In the AMG GT, the newly developed engine produces 462 PS (339 kW) and 600 Nm (442 lb-ft) while in the AMG GT S it packs a 510 PS (375 kW) and 650 Nm (479 lb-ft) punch. Regardless of the engine version, output can be bumped to 630 PS (463 kW) and 725 Nm (535 lb-ft) which will increase top speed to 209 mph (337 km/h).

As for the C63 and C63 S, POSAIDON can work on the engine and increase its output to 610 PS (449 kW) and 800 Nm (591 lb-ft). They will also remove the 155 mph (250 km/h) electronic top speed limiter, thus enabling the high-performance sedan hit a maximum speed of 204 mph (328 km/h).

The tuner says additional upgrades are in the works as both cars are bound to receive modified turbochargers, free-flow exhaust systems and other tweaks which will lift output even further.
