There are tuning packages, custom builds, and then there is this SpeedKore Performance "Tantrum." While you may have not heard of the Wisconsin-based shop, you've seen their work before in Furious 7 with the 1970 Plymouth Barracuda. Next, the shop turned their focus on a 1970 Dodge Charger, lowering its carbon fiber body treated with a gleaming finish, fitted with an intricate grille, and LED headlamps with mirrors, handles, and accents in a matching aluminum. Under the hood, there's a DOHC 9.0-liter twin-turbocharged Mercury Racing - as in Mercury Marine boat engines - V-8 crate engine with a massive 1650 HP. Currently, the Tantrum isn't for sale, but its power, inspiration, and beauty is free for the masses to admire.
