German tuning company Posaidon has managed to take one of Mercedes-AMG’s most impressive models and make it even faster. It’s known as the Posaidon GT 63 RS 830+ and is based around the Mercedes-AMG GT 63 S 4Matic+.
Ordinarily, the 4.0-liter
twin-turbocharged V8 engine of the GT 63 S 4Matic+ pumps out 639 hp, making it
one of the most powerful and fastest vehicles in its segment. Not satisfied
with that figure, the tuner has fitted a pair of new ball-bearing turbochargers
while also overhauling the intake system, intercooler system, and cylinder
heads.
In its unrelenting pursuit of power,
Posaidon has also optimized and expanded the intake and exhaust ports, added
water/methanol injection, and fitted a new exhaust system with unique downpipes
and high-flow cats. The ECU has also been tuned and the upgraded sedan now
delivers 940 hp and 1,278 Nm of torque. Those are some serious
figures and the water/methanol injection system is a unique touch, enhancing
boost pressures without subjecting the engine to higher thermal loads and
running off a tank beneath the floor of the trunk.
In a straight line, the GT 63 RS 830+
dispatches of the sprint to 100 km/h in a mere 2.8 seconds and needs
just 5.9 seconds to accelerate from 62 mph to 200 km/h. It will also
top out at over 350 km/h. Posaidon will only sell its 830+ package to
customers outside of Germany. Those who live in Germany will need to settle
with 830 hp and 1,100 Nm.
