Mercedes-AMG C63 / C63 S (W205 · M177 4.0L Twin-Turbo V8) — Stage 3 Power Package
The same M177 turbo platform that ran the world's first sub-10-second Mercedes-AMG C63 W205 quarter mile — 9.97 seconds at 828 WHP, set at Beech Bend Raceway Park, Kentucky on April 9, 2019. This package puts that proven hardware combination in your car: 1,000 HP-rated turbos, unrestricted exhaust flow, and an ECU calibration developed on the platform that holds the record.
Performance — Stock vs Stage 3
| Spec | C63 Stock | C63 S Stock | Stage 3 (Pump Fuel) |
|---|---|---|---|
| Peak Power | 476 HP | 510 HP | 800+ WHP |
| Peak Torque | 650 Nm | 700 Nm | 950+ Nm |
| Turbo Hardware | Factory IHI | Factory IHI | YPG 1,000 HP+ Rated |
| Exhaust Flow | Catalyzed | Catalyzed | Catless Full-Flow |
On E85 or methanol supplementation with forged internals, 1,000+ WHP is achievable on this hardware.
What's Included
- YPG Stage 3 Turbo Upgrade (M177) — 1,000 HP+ rated turbochargers, drop-in fitment, factory wastegate actuation retained ($5,799 individually)
- YPG Catless Downpipes (W205 C63) — mandrel-bent stainless steel, required for Stage 3 boost targets ($1,499 individually)
- YPG Stage 3 ECU Calibration — boost, fueling, ignition timing, and torque limiters all revised for the upgraded hardware. Delivered via YPG Flash with datalog-based revisions until the car is dialed ($2,000 individually)
Package price: $8,799 — saves $500 vs buying separately ($9,298).
Who This Package Is For
Owners who have outgrown Stage 1 and Stage 2 power and want a serious jump — the kind of power that transforms the W205 from a fast sedan into a legitimate drag strip weapon or roll-race car. If you're chasing 9-second quarter miles, building a 1,000+ HP street car, or want turbo hardware with headroom to grow into a full Stage 4 build later, this is the starting point. YPG Motorsport has been building M177 platforms since 2016 and holds the world record on this exact chassis.
Why a Matched Package From One Builder
Stage 3 power depends on the turbos, exhaust flow, and calibration working as a system. The ECU calibration in this package is developed specifically for these turbos and these downpipes — not a generic file layered over mixed hardware from different vendors. One order, one shipment, one calibration file, one team responsible for the result.
Delivery & Support
Hardware ships worldwide. GCC delivery to Kuwait, UAE, Qatar, Saudi Arabia, Bahrain, and Oman via FedEx International Priority (1–3 business days). ECU calibration delivered remotely via YPG Flash — no need to ship the car. Datalog-based revisions included until the car is right. Installation available at YPG Motorsport Kuwait or through your local performance workshop.
Common Questions
Do I need forged internals for Stage 3?
For power levels up to approximately 800 WHP on the M177, the factory internals can hold — but you are near the limit. If you plan to push beyond 850 WHP, run E85, or drag the car regularly, forged rods and pistons are strongly recommended. YPG offers M177 forged internals rated for 1,500+ HP.
Can I run Stage 3 on pump fuel?
Yes. The calibration is developed for 95–98 RON (91–93 octane) pump fuel as the baseline. For maximum power beyond 900 WHP, E85 or methanol injection is recommended with a fueling upgrade.
What's the difference between Stage 2 and Stage 3?
Stage 2 maximizes power on factory turbochargers (typically 550–600 WHP on the C63). Stage 3 replaces the turbos entirely with higher-capacity units, adds catless downpipes, and includes a calibration developed for the new hardware — a significant hardware change, not just software.
Does the tune work with other modifications?
The Stage 3 calibration works alongside intake upgrades, intercooler upgrades, and exhaust modifications. If you add fueling upgrades (port injection, larger injectors) for E85 or methanol, a recalibration revision is included to match.
