M3R McLaren Package, 1700HP Complete Engine Build & Transaxle Build

The M3R was engineered as an integrated 1,700 HP vehicle, not an engine with oversized turbochargers attached to it. Achieving this level of performance requires the engine, turbo system, fuel system, cooling, thermal management, transmission, driveline, electronics, traction control, and calibration to operate together.

Every system has been developed around the demands created by the next. That's why the M3R incorporates extensive engine and cylinder-head preparation, EFR9174 turbochargers, advanced fuel delivery, reinforced driveline components, and sophisticated vehicle control strategies. The horsepower figure is the result of the engineering—not the engineering goal by itself.

Our performance packages deliver significant power increases: M1R up to 1400HP, M2R up to 1550HP, and M3R up to 1700HP. Each package includes full engine and transaxle builds, custom 3D printed parts, Syvecs ECU with map switching, and comprehensive TCU/CCU tuning.

Making 1,700 HP is one challenge. Getting a rear-wheel-drive McLaren to effectively use it is another. Mega 3 Performance utilizes an extremely advanced traction-control and torque-management strategy that continuously analyzes individual wheel-speed relationships—not simply whether the rear tires are spinning.

Our strategy evaluates wheel speeds left-to-right, front-to-rear, and diagonally across the vehicle, allowing the control system to recognize traction events and manage engine torque with exceptional precision. The result is controlled power delivery designed to maximize acceleration rather than simply cutting power whenever wheelspin occurs.

At M3R power levels, the transaxle and driveline must be engineered with the same attention as the engine. The package combines an upgraded clutch system with Mega 3 Performance billet axles, billet LSD differential, billet differential cover, reinforced gearbox components, and precision ring-and-pinion setup.

These upgrades address the enormous sustained and instantaneous loads created by 1,150 lb-ft of torque, particularly during launches and aggressive acceleration. Combined with our transmission calibration and torque-management strategies, the objective is not simply strengthening individual parts—it is creating a driveline engineered to function as a complete system at extreme power levels.

The M3R's fuel system is engineered around delivering consistent fuel volume and pressure under conditions far beyond the capabilities of the factory system. It incorporates a quad-pump fuel system, billet surge tank, upgraded fuel rails, high-flow injectors, and dedicated fuel-pressure monitoring to support the demands of the M3R engine.

The surge-tank architecture also helps maintain a consistent fuel supply during hard acceleration and other high-load conditions. At this level, fueling isn't simply about installing larger injectors or pumps—it requires engineering sufficient capacity, pressure stability, and monitoring into the complete system.

Absolutely! We provide a comprehensive 2-year/24,000-mile limited powertrain warranty with all our builds. Our confidence in the quality and reliability of our work allows us to offer warranty coverage that exceeds what any other McLaren tuning specialist provides.

We maintain inventory of our engine and M3P driveline parts, which enables us to complete McLaren builds within 3-4 months. This timeline could be subject to change based on volume increases, which would be clearly disclosed at the time of build slot reservation.

All of our calibrations are written and developed in-house and not outsourced. Our calibrator is owner/engineer Safa, who has been tuning for 15 years and is currently the only person in the world to unlock full control of the McLaren TCU. Safa's expertise extends to developing calibrations for the TCU and CPC controller for Mercedes platforms, plus ECU and TCU tuning for many of today's popular high performance European cars.

All our M3P transmission and driveline parts are designed, engineered, and manufactured in the USA. We have invested heavily in our driveline offering to ensure maximum reliability and performance for high-horsepower McLaren applications.

The McLaren TCU tuning solution is exclusively available for our client builds only. The TCU calibration is a critical component that works in conjunction with our ECU tuning to achieve the full power potential and driveability in our comprehensive powertrain programs.

Yes, we specialize in high-performance tuning for McLaren, Mercedes-AMG, Ferrari, Lamborghini, Porsche, and other exotic vehicles. Our expertise covers ECU tuning, TCU optimization, and comprehensive powertrain upgrades for various supercar platforms.
