One of the finest cars built by General Motors, the Cadillac CTS-V has been improved by the tuning firm Hennessey Performance. There’s always room for improvement when you get to work with a factory supercharged 6.2-liter V8 engine. Hennessey Performance has developed the V700 upgrade package to squeeze an extra 150 horses out of the Cadillac CTS-V LSA V8, giving it more than 700 horsepower. It was accomplished with the addition of a cold air induction system, smaller supercharger pulley, new engine management system, longer headers, 3-inch exhaust system, high-flow cats, upgraded intercooler, and more aggressive camshafts. The end result?
