850 HP Challenger Hellcat Drag Races Tuned Porsche 911 Turbo S with Oil on Track

You can never fully trust the output of a modded street car until the thing gets put through its paces in the real world. For instance, using two such machines in a drag strip battle is a brilliant way to check out their abilities.

And when the cars in question happen to be a Dodge Challenger Hellcat and a 991.1 Porsche 911 Turbo S, the good times are guaranteed, even when an oil spill stands in the way of the mph work.

This is exactly what happened in the race delivered by the piece of footage at the bottom of the page, which saw the rear-engined coupe experiencing wheelspin while going from first to second gear – given the kind of seamless shifts the PDK double-clutch transmission delivers, such issues rarely affect Neunelfers.

We can only imagine the frustration experienced by the guy behind the wheel of the Porsche, especially since, as you’ll be able to see in the video, the man delivered a brilliant reaction time.

In terms of the aftermarket approach used by these speed demons, the Porsche only packs a Tubi cat back exhaust, as well as a GIAC-supplied ECUremap. The driver of the supercar, which delivers 560 hp and 553 lb-ft of twist in factory stock form, wouldn’t mention the new output of the beast.

As for the Hellcat, the blown 6.2-liter heart of the thing has been gifted with a custom pulley, a cold air intake, long tube headers and an ECU remap, with the car running on race fuel. The power chain equation of this Dodge also involves a modded rear end with a 3.09 final drive.

While the video talks about the Hellcat now delivering 850 hp at the wheels, which would mean its crank output has jumped to over 950 ponies, we’re not really sure about this value.

The rubber battle? The Porsche’s all-wheel-drive means the owner could stick (no pun intended) to the factory setup, while the clip below will allow you to see the Hellcat roasting its 18-inch slicks.
