Posaidon is a firm believer that tuning jobs should include a huge bump in power and not much else, and their upgrade kit for the Mercedes-AMG S63 Coupe follows this recipe to the letter. Priced at € 52,000 (US$ 63,048) in Germany, the ultimate stage of their 830+ tune bumps the output and torque of the twin-turbo 4.0-liter V8 from 612 PS and 900 Nm to 940 PS and 1,280 Nm.
This was achieved by using
high-performance turbos with ball bearings, downpipes with sport catalytic
converters, a sport air filter, cylinder head porting, valve seat alternations,
a water/methanol injection system with optional tank, and engine and
transmission software remap. The result is 2.8 seconds required for the 0 to
100 km/h sprint and a 350 km/h limited top speed to
preserve the tires.
The tuner also has more tamed upgrades in
store, like the one that ups the output to 880 PS and 1,200
Nm. It costs € 29,990 (US$ 36,362) and allows the luxury coupe to hit
100 km/h in 2.9 seconds, while top speed is still capped at 350 km/h. This kit makes do without the aftermarket injection system, valve
seat alterations and cylinder head porting of the previous tune.
In return for € 24,000 (US$ 29,099), the stage
2 uses upgraded turbochargers to increase power to 830 PS and
1,100 Nm, for a 0-100 km/h in 3.0 seconds. Stage 1,
which utilizes only a software upgrade for the ECU, is priced at a more
down-to-earth € 4,200 (US$ 5,092) and offers 700 PS and 950 Nm. This version has a maximum speed of 330 km/h and hits
the 100 km/h mark in 3.2 seconds from a standstill.
On a final note, Posaidon said that they
are working on the ultimate upgrade for this lump, which will exceed 1,000 PS, and just like the ones that are already available, it will
suit all Mercedes-AMG models that use the 4.0-liter bi-turbo V8.
