Matt Farah just got his hands on this brute from the folks at Weistec Engineering. They took an E63 AMG and managed to get 850 hp and nearly 900 lb/ft of torque from a 5.5L Twin-Turbo V8. That’s a big improvement over the stock 557 hp. This thing sounds mean as hell of and of course Matt managed to smoke the hell out of the tires all over So Cal. Check it out after the jump!
