McLaren M840T - Stage 3 Power Package 720S

The Stage 3 Power Package by M-Engineering enhances the McLaren 720S, 765LT, 750S, GT, and Senna with a set of Pure Turbo PT1200 Turbos (McLaren GT uses PT900 Turbochargers due to a different exhaust manifold design) in addition to the Stage 2+ Power Package. This kit is capable of producing in excess of 1100WHP on race fuel for the McLaren 720S/765LT/Senna. For stock engines, the power output is recommended to be limited to 1050whp. The package includes the M-Tuner Calibration Suite, M-Tuner Motorsport Tuning Package, and Injector Dynamics ID1050x Injectors with an M-Engineering Injector Harness by Race Spec. It features live map switching, allowing users to switch between pump gas and race fuel using the cruise control stalk. Downpipes are highly recommended but not included, and custom tuning is also suggested to maximize the package's potential. A note for 720S owners: as the vehicle ages, the OEM fuel pump may require replacement or an upgrade to a twin pump setup, with brushless upgrades being heavily recommended.
