Big power upgrades for McLaren LT
Hennessey admits 765 makes more power than claimed
Texas tuner Hennessey Performance has just announced a plan to turn the McLaren 765LT into something more like a 1000LT. The car will be the quickest and most powerful McLaren Hennessey has offered yet, though the tuner himself revealed it’s not quite the accomplishment it looks to be.
The 765LT is a factory long-tail special. The longer rear adds downforce for stability at top speed, and the 765 figure means that the car is said to mark 755 hp and 590 lb-ft of torque – that’s 765 PS if you’re confused – and it can run the quarter-mile in 9.9 seconds.
With the help of engine tweaks large and small, Hennessey has upped the power figure significantly. The changes include high-flow air filters and the pre-requisite ECU recalibration as well as stainless steel downpipes. Then there are the most important parts of any car like this, loads of HPE1000 badges and a serialised plaque for the dash and engine.
It’s enough to push the Macca from 0-100 km/h in 2.1 seconds, making it one of the quickest-accelerating cars in the world. A surprise, though, comes in the price, just US $24,950 for the upgrades to the car including installation and fluids.
The power increase is also not what you might expect, though John Hennessey is upfront about it. “The new 765LT is underrated from the factory. We tested it on our in-house dyno and it delivered about 765 HP – at the rear wheels. This means it’s producing closer to 865 bhp in bone stock form,” he said. So while the completed car makes 1,000 hp, it’s a 135 hp upgrade, not a 235 one. We’re not sure you’ll care, though, once you achieve that 0-100 km/h run.
