Litchfield Motors Stage 2 McLaren 720S M840T tuning package produces 847 horsepower

[Sticky]

The McLaren 720S really is a marvel of a machine. Not only is the car stupid fast in stock form and responsible for raising the performance bar to absurd levels McLaren left plenty on the table for those who want more. Kudos to McLaren there.

What the Stage 2 package consists of is catless downpipes from Milltek plus a Litchfield tune on 93 octane fuel.

It would be nice to see the baseline but getting MAHA dyno figures is also good to see for those of us in the US where Dynojet and Mustang dynamometers are prevalent:

847 horsepower at the crank with a conservative 726 horsepower at the rear wheels. The MAHA is very stings with wheel output.

Regardless, the 720S shows absurd power with minimal modifications.
