Earlier this month we featured a video of a Cadillac CTS-V Coupe on the dyno which produced a stratospheric 1,444 horsepower at the wheels, making it the most powerful recorded CTS-V in existence. Now the builders of the car, LStuner.com and SNL Performance, have sent over some additional information on the manic CTS-V along with a new video of the car driving.
To help produce those insane power numbers, SNL Performance swapped out the stock 6.2-liter LSA engine in favor of a 7.1-liter LSX iron-block. They then added a pair of 62 mm turbochargers, an air-to-water intercooler, Mast Black Label cylinder heads and a Wilson intake manifold. The result was an engine which produces more than 1,600 horsepower at the crank and 1,444 horsepower at the wheels. All that power is being sent through a 4-speed automatic transmission which LStuner says has been repurposed from an old heavy-duty truck.
The builders of the car say it is not a race car and it still possesses its easy-going Cadillac qualities. That means it retains the original engine management computer as well as the air conditioning, power steering, back up cameras, parking assist, heated seats and cruise control. It might not make the best daily driver though, as it gets 10-12 mpg, and that’s when you’re not unleashing all 1,600 tire-shredding ponies on the rear tires. Scroll below to see the car in action.
