Stage 3 Power Package

The M-Engineering M840T Stage 3 Power Package enhances the already powerful Stage 2+ configuration by incorporating a set of Pure Turbo PT1200 turbochargers. This comprehensive kit is designed to deliver significantly increased power output, with proven performance well in excess of 1100WHP on race fuel for models such as the McLaren 720S, 765LT, and Senna. For stock engines, M-Engineering recommends limiting the power output to 1050whp to ensure longevity and reliability. This package includes the M-Tuner Calibration Suite and the M-Tuner Motorsport Tuning Package, enabling advanced features. The kit also contains Pure Turbo PT1200 Turbochargers (core exchange required) and Injector Dynamics ID1050x Injectors with an M-Engineering Injector Harness by Race Spec. A standout feature is the live map switching, allowing users to seamlessly toggle between pump gas and race fuel tunes with a simple flick of the cruise control stalk. It is important to note that this kit does not include downpipes, which are highly recommended for optimal performance. Custom tuning is also advised to fully unlock the potential of this power package. For McLaren 720S owners, M-Engineering advises that as the vehicle ages and the OEM fuel pump filter collects debris, it may be necessary to replace the pump/filters or upgrade to a twin pump setup; brushless upgrades are particularly recommended over traditional brushed pump upgrades. *Note*: The McLaren GT model utilizes PT900 Turbochargers instead of the PT1200 due to differences in its exhaust manifold design.
