The Lamborghini Countach was produced from 1974 to 1990. The Countach Turbo S was only made in 1984. There were only 2 Turbo S models ever built as prototypes.
When Lamborghini installed the twin-turbo system they also beefed up the chassis to handle the extra power. The engine is a 4.8L V-12 that includes six carburetors. This car can do 0-60 mph in 3.6 seconds with an impressive 208 mph top speed.
One of the most incredible features of the Turbo S is the boost adjustable dial switch. On the lowest turbo setting the car makes around 510 hp at 10.2 psi of boost. The max turbo boost setting produces a monster 747 hp with 646 ft-lbs of torque at 21.8 psi.
