Dodge is gearing up for a full reveal of the hotly anticipated Challenger SRT Demon this evening, but it looks like one of the biggest question marks just got spoiled a few hours before the big debut. According to a rash of leaks on social media, the Demon will produce upwards of 1,023 horsepower in its most potent drive configuration.

According to a variety of sources, including Instagram account @thedarkestride, the Demon will come with three separate power modes, each offering progressively greater levels of output. Mode 1 will be good for 757 horses, Mode 2 will be good for 815 horses, and the top Mode 3 will make that jaw-dropping 1,023-horse figure already mentioned.

The leaks go on to specify that Mode 3 requires a tank filled with fuel with at least a 100-octane rating, a new Power Control Module (PCM) tuned for the ultra-high-test juice (a $3,000 option), and the appropriate “Drag Mode” setting selected in the cockpit.

Whether or not the leaks are accurate remains to be seen, but either way, the Demon should manage to post numbers above and beyond those of the already insane 707-horsepower Challenger Hellcat.

We’re very excited to see what happens this evening when Dodge SRT spills the beans with the official debut. For now, read on for a little last-minute speculation.

Over 1,000 Horsepower? Seriously?

Oh yeah, baby. This is where things start getting really wild. As if the Hellcat wasn’t outrageous enough, the Demon is looking to take things to a whole new level of crazy. If @thedarkestride is to be believed, a rock-stock Demon will make more horsepower than the multi-million-dollar LaFerrari hybrid hypercar, but for a fraction of the cost. It’ll run the quarter mile in the 9-second range, and with just a few mods, break into the 8’s.

Without a doubt, this is the biggest salvo in the new-and-improved horsepower wars launched in recent memory. But getting all that power to the ground reliably will be a trick in and of itself. Initially it was believed the Demon might swap RWD with AWD, but recent teasers seem to disprove that theory with big RWD burnouts, not to mention an allusion to fitting skinny tires to the front corners in traditional drag racer fashion.

@thedarkestride also contends that the internals were beefed up to handle all the extra output, and the driveshaft was fortified. Makes sense, if you ask us.

The next question is what kind of tunability should we expect? Where will the quest for speed end? Can 1,023 horses really be nothing more than a starting point?

It’s all pretty insane to think about. Check back tonight for the answers.
