Time for a rematch between a tuned Porsche 911 GT2 RS and a McLaren 720S.

Last time we saw these two cars go head to head was last January at DragTimes home strip, the Palm Beach International Raceway. This time they once again meet up at the Fuel Run Rally in Miami for some a good, old-fashioned rematch. Which also takes place at Palm Beach, so it’s extra fair.

It looks like the Porsche owner has spent a little more time on the dyno since now we have a more precise power figure. Thanks to a new exhaust and a full tune that involves some racing fuel, this Porsche 911 GT2 RS now makes 830 hp instead of the 690 it was born with. That’s 120 more horses coming out of its twin-turbo straight-six engine than what comes from the 720S’s big V8.

But you know what they say: never count out a McLaren, even when it’s at a power disadvantage. Those British eggheads have somehow managed to stuff some magic inside that 4.0-L twin-turbo V8 that belies its reported 710 horsepower. We’re not sure what it is, but the 720S never fails to impress.

Which is exactly what we get on this first run. The Porsche 911 gets an early lead, but soon after launch the 720S starts to crawl its way back. It’s a photo finish by the time they reach the quarter-mile, with the 720S taking the win by just 0.01 seconds.

The final slips might seem a little confusing since it says the McLaren posted a time of 10.16 seconds at 140.58 mph while the Porsche managed 10.15 seconds at 137.58 mph. Those times are calculated from when the individual car starts and stops, and not from when the tree’s light hits green. The time at the bottom of the slip determines the winner based on when the race starts and whoever crosses the finish line first.

There are two more races to in this rematch, so check out the video to see who wins.
