Dual Dyno Tests Suggest McLaren 765LT Is Seriously Underrated
Two dynos at different locations reveal massive numbers, but there's a catch.
We were ready to be skeptical about this report. Here's why – Dragtimes put a McLaren 765LT on a chassis dyno and pulled 770 horsepower at the wheels. Remember, wheel power is less than crankshaft power, which is where automakers get their official ratings. In this case, the rating for the 765LT is 755 hp, so either McLaren underrates its engine by over 100 hp, or there's something goofy with the numbers. More on that in a bit.
We were ready to question everything from the dyno setup to whether the car was stock, but here's why we aren't nearly as skeptical as we were at the beginning of this saga. We came upon another 765LT dyno test, coincidentally posted today from Hennessey Performance. And you know what? Their pull was even higher, 780 to the rear wheels to be exact. Yes, 780.
