McLaren 765LT enjoys a boost to 1,000 HP

Hennessey Performance measured the performance of the McLaren 765LT on a dyno in early February, concluding that the supercar delivers more punch than its paper specs care to mention. Even so, the tuner resolved to raise the output to 1,000 horsepower at the crank and cut the sprint time down to just 2.1 seconds.

The previously measured brake horsepower at the rear wheels was 765 PS (755 hp / 563 kW), which we would be tempted to call in line with the specs if it hadn’t been for the fact that the specs are supposed to reflect ‘pure’ engine hp. With 765 PS reaching the wheels, the engine has to put out at least 865 PS (853 hp / 636 kW). At any rate, the 765LT is a wild beast to drive straight from the factory, being able to accelerate 0-100 km/h (0-62 mph) in 2.8 seconds and complete a quarter-mile run in 9.37 seconds.

Installing the full HPE1000 kit should reduce the launch time to 2.1 seconds and raise the top speed beyond 346 km/h (215 mph). The kit costs U.S. $24,950 with installation and also includes high-flow air filters, a stainless-steel downpipe, an ECU remap, and more. Those who feel they must have something to show for all the tuning may opt for special badges and plaques.
