The Porsche 911 Turbo S is a phenomenal sports car that borders on the super. It's a delight to drive and handles beautifully, which is what Porsches have always been about, but recent iterations of the icon have been proving their potential in a straight line too, as we've seen from numerous drag races. Add some tuning to the mix, and these cars really wake up. More proof of this can be seen in the video below, where modified 991.2 and 992 variants of the Turbo S are pitted against each other in a drag race. The newer model is a cabriolet, but both are damn quick.

The 991.2 version is a 2018 model running a Champion/GIAC 100-octane tune and a Tubi Race catback exhaust system with stock manifolds. As a result, the coupe has been boosted from 580 horsepower to 620 hp at the wheels, which equated to a 100-hp increase on the wheels.

The convertible 992, on the other hand, is running a DME tune and catback exhaust, and has been upped to approximately 630 hp at the wheels, which is claimed to be around 730 hp on the crank - more than you get in a McLaren 720S.

Interestingly, it's the less powerful 991.2 that takes the win in a head-to-head race, but closer inspection reveals that the coupe is running semi-slick tires while the convertible is on road tires. The convertible is also heavier, but both post respectable times. The 991.2 managed a 9.85-second pass at 137 mph while the 992 achieved 10.08 at 138 mph. Later in the day, both cars run their best times yet, with the coupe managing an astonishing 9.78 seconds and the 'vert crossing the line after 9.91 seconds. For such basic modifications, these are astonishing times. We'd love to see it come up against the Dodge Demon.
