Who might get a 552 horsepower Cadillac CTS-V and say: Damn, it ain’t fast enough! Well, guys of Hennessey Performance do! And they realize some of you out there might be just as nuts so they offer four levels of engine tuning for this small block LSA ranging from 610 to 800 hp! To achieve this figures they rip the  standard engine apart and then throw almost all of the parts away! replacing them with performance parts.

Some of changes include adding a new cold air intake system, sport stainless steel exhaust headers , high flow manifolds, totally modified cylinderhead to house a new camshaft and the Eaton supercharger with a big intercooler and of course ECU remapping. What Hennessey has done to the engine shows its great capabilities. It’s amazing how flexible is this LSA carat. Future sports cars by GM should have no worries about the engine,at least!
