The CTS-V will inevitably go down in automotive history as one of General Motors’ best efforts at offering a luxe high-performance sedan. Even its first attempt that hit the pavement in 2004, was an impressive car for its time. But as the years wore on, and Cadillac raised the bar with each new generation.
The final generation, was the 2016-2019 third-gen, that V enthusiasts refer to as the “V3.” It packs the same LT5 as the current CT5-V Blacking, the CTS successor, with slightly less horsepower. Even today, 650hp at the crank from the factory is nothing to scoff at, but let’s not forget that we’re talking about a modern GM LT-series engine, with a supercharger, here.
These engines love mods, and Erik at Florida High Performance is a master at his craft. Coaxing out four-digit power is certainly doable, when he’s manning the wrenching, and the keyboard. Of course, it helps if you have the right ingredients for the recipe, and Erik knows how topcike them as well.
A Roto-Fab Big Gulp cold-air intake has gone into the mix, as did a Magnuson supercharger — replacing the OEM unit. More air flow for better efficiency, creating more power and torque is the idea here. Another note-worthy add-on, relatively new to the industry, are the Too High PSI port plates that install between the exit ports of the supercharger base, and the cylinder heads
Brian Tooley Racing set the car up with a set of Haltech 950cc injectors and ECU, while Fore Innovations takes the fuel system to the next level with their dual-pump system harness, relays, pumps, etc., keep the fuel flow on point with the rest of the combination. A WeaponX Motorsports heat exchanger keeps blower intake temps in check, too.
There’s more than went into the car, but to get ALL of the nitty gritty details, you’ll have to see what they are in the video clip above. However, we will tell you that the car made 980 horsepower, and 852-lb ft of torque to the rear tires on 19-lb of boost.
