Carbon Fiber Demon by Speedkore is a Lightweight and Hardcore Beast
The crew at Speedkore subtracted weight and added a lot of power to make the Dodge Demon more diabolical than ever before.
There are two main ways to make a car faster: reduce its weight or give it more power. Some people swap out their stock wheels for lighter replacements and throw out their rear seats to cut some pounds. Others make tweaks under the hood to increase the figures on their dyno readings. As this YouTube video from AutotopiaLA shows, the gang over at Speedkore did both with this 2018 Dodge Demon.
According to the Grafton, Wisconsin-based shop’s website, they built “Big Machine” for Scott Borchetta, president and CEO of the Big Machine Label Group. Instead of removing certain parts to save a few pounds here and there, Speedkore replaced the steel body, top to bottom, with lightweight carbon fiber. They also threw in a cool bonus feature on the front fenders. The regular Demon badges look cool enough, but on Big Machine, they light up – in red, of course. Unfortunately, Speedkore didn’t say how much weight the carbon fiber panels saved. Whatever Big Machine tips the scales at, it’s bound to be significantly lighter – even with its 14-point roll cage – than it was in its 4,280-pound stock form.
David definitely knows how much power Big Machine has. Aside from a new Whipple supercharger, it’s equipped with “a custom cold air intake, … bigger throttle bodies, … [and] bigger injectors.” All of those mods give Big Machine 980 horsepower – at the wheels. Assuming a 15-percent parasitic drivetrain loss from the crankshaft to the back end, that means Big Machine has got roughly 1,153 horsepower under its glossy hood.
It routes its insane amount of net horsepower through 305s at all four corners (the stock Demon used 315s). Do the math and you’ll see a huge potential problem for Big Machine. Davis does. “In my opinion, this should have a 345 on the rear to at least do its best to try to get some grip. With traction control on and 50, 60, maybe 70 percent input at the accelerator, this car’s breaking loose.”
You can see exactly what Davis is talking about at the 5:32 mark. He gets into the throttle and has to correct the steering with both hands as the tires chirp and the back end squirms. Big Machine was built to go forward quickly, but it clearly wants to go a little sideways before it does. Davis uses an appropriate word to describe the power he just experienced: “brutal.”
A little later, he wields that against his buddies who are traveling in a built Cadillac CTS-V wagon with 750 crank horsepower. Even flat out, it’s no match for Big Machine at half throttle. Who knows how much Davis would’ve gapped them if he floored it? Given that Big Machine isn’t his car, he isn’t willing to go 10 10ths in it. We respect his restraint…and hope that Borchetta has fully indulged in his privileges as Big Machine’s owner.
