The shenanigan took pace at the Atco Raceway yesterday and put an end to the 8s race, which had been going on for quite some months.
Perhaps the most impressive part of the feat is that the British supercar still used street tires, albeit not the factory rubber, as it ran on 20-inch Toyo R888Rs. Note that a set of tire warmers was used on the day of the run, but things didn't exactly come easy.
As you'll get to see in the piece of footage below, which documents the shenanigan, it took multiple runs to achieve the said feat.
When it comes to the gym visit of the Macca, this involves Pure Turbos, a Velocity custom exhaust with a decatted setup, as well as a DME tune. And, according to a recent dyno trip's results, the twin-turbo 4.0-liter V8 of the toy jumps from around 750 hp (this is the actual factory output, as the official 720 hp is an understatement) to about 1,050 hp - we're talking about 943 horses at the rear wheels.
So it seems that the transmission and the rear differential are still the factory units, while there's no talk of any weight reduction, which means you can still use the climate control.
Of course, the next step will be to see what the 720S can do on drag radials, so you shouldn't imagine that the sprinting efforts stop here.
Oh, and in case you're wondering, a factory McLaren 720S can play the quarter-mile game in as little as 9.7s, albeit on the same Toyo rubber, with this allowing it to one-up the P1.
