The Dodge Challenger SRT Demon is already a monster straight from the factory. With 840 hp coming from its supercharged 6.2-liter Hemi V8, it's hard to top this street-legal drag racer. Or is it? Look no further than what the folks at aftermarket tuning firm Speedkore have created: a twin-turbo, carbon fiber-bodied Dodge Demon, set to officially be unveiled at this year's SEMA show in Las Vegas. Gone is the famed supercharged, replaced by two 6875 Precision Billet ball-bearing T4 turbochargers.

All told, this Demon makes 1,400 hp at the flywheel, which translates to 1,203 ponies at the rear wheels. And yes, it does look mostly stock from the outside, but a closer examination reveals something pretty darn awesome: carbon fiber. Lots of it.

Speedkore went to great lengths to replace all of the car's body panels with carbon fiber replicates. Total weight is also down (though Speedkore didn't provide an exact figure) and, along with the power boost, performance is also improved. Compared to the stock Demon's 9.65-second quarter-mile time, this thing will do the deed in just 8.77 seconds at 62 mph – nearly a full second faster.

We've seen some of Speedkore's past crazy creations, such as a 1,650 hp 1970 Dodge Charger restomod and some Ford Mustangs, all of which featured power increases and lots of carbon fiber. The basic formula is this: shave weight, add power. That simple.

We'll get more details during SEMA in Las Vegas in a few weeks' time, but we can tell you this 1,400 Demon build isn't cheap. Those interested will have to fork over another $64,000 on top of the car's regular price tag. Be sure to also check out the included YouTube video Speedkore made showing the Demon's build and how its body panels were swapped for the carbon fiber units.

SEMA will get underway starting October 30 until November 2.
