AMG GT S — YPG9XX Package
Stage 3 Turbos · Methanol · 9XX HP Crank · Kuwait Motor Town Proven
The Mercedes-AMG GT S M178 is already one of the most capable platforms in the GCC — a 4.0L flat-plane twin-turbo V8 with DNA engineered for performance from the factory. The YPG9XX Package takes that foundation and restructures it entirely. Stage 3 turbochargers, methanol injection, and a full supporting build combine to push crank output into the 9XX HP range — while maintaining the reliability and drivability expected from a YPG-developed vehicle.
Package Components
| YPG Stage 3 Turbo Upgrade | Billet compressor wheel, upgraded turbine, ceramic-coated housing — plug-and-play fitment on the M178. 900+ HP capable. |
| Methanol Injection | High-flow methanol system with charge-cooling chargepipes — drops intake temps, raises knock threshold, enables aggressive timing and boost. |
| Catless Downpipes | Unrestricted exhaust flow to match the increased turbo output. Direct fitment for AMG GT/GTS. |
| M178 Forged Internals | Forged rods and pistons — the mandatory foundation for sustained 9XX HP output under track and street conditions. |
| Custom ECU Calibration | Full custom calibration developed on methanol — optimised boost, fuelling, timing, and torque delivery specific to this build. |
| Supporting Hardware | Blow-off valve, high-flow air filters, carbon air inlets — all optimised to feed and support the Stage 3 turbo system. |
