The high-performance luxury market changed dramatically in 2003 when the
General Motors Performance Division was interwoven with the Cadillac brand. The collaboration was designed to bring the fight to the European performance brands, and it succeeded with the V-series package. A factory racing program was simultaneously launched to showcase the team’s engineering prowess on the racetrack. Over 20 years later, Vengeance Racing is continuing the V-series motorsport excitement—except we don’t think their version lines up with the original corporate business plan.
If you aren’t familiar with Vengeance Racing, let us give you the quick, high-level overview—the *******, Georgia-based motorsport facility is one of the leading late-model performance shops in the country.
Ron Mowen opened its doors in 2006, first catering to GM platforms. Over time, the shop has grown to include all domestic performance brands. Around six years ago, Ron came across a deal that was too good to be true: a chance to get a customer’s 2011 Cadillac CTS-V coupe for his wife as a Mother’s Day gift. Through a little horse-trading of services and parts, the Caddy came into the Mowen family as Misty Mowen’s street car. This wasn’t just any V-series; this one arrived with a supercharged LS-stroker engine that at one time pushed the luxury coupe into the 8s at around 160 mph.

A Diamond in the Rough
We won’t call it a barn find like what we normally come across, but the Caddy had seen cleaner days considering it was less than 10 years old. The problem was that the car had broken a few years earlier and the previous owner parked it in storage. Misty wasted no time getting her new whip ready for action by removing the dust, grime, and cobwebs that had formed. A short time and many cans of cleaning solvent later, she was doing burnouts and having fun at the dragstrip.
The family business is selling speed, so in those six years of ownership, the car has seen an evolution from a supercharged combination to its current twin-turbo setup. The formerly black-colored V-series had also been painted white, a traditional vehicle color in the Mowen household.

Get Out and Race!
It isn’t every day that you see luxury sedans throwing down 8- and 9-second performances at the dragstrip, but that is a common sight at Street Car Braggin’ Rights, an annual shootout held at Carolina Dragway in Aiken, South Carolina. The event brings together a wide range of late-model vehicles and muscle cars through various heads-up eliminators. Misty’s
CTS-V fits right in with that crowd, and she was entered in the Heavy Weight and No Time Overdrive Shootout categories. The Heavy Weight class requires vehicles to be a minimum of 4,200-pounds, have functioning A/C, and roll on DOT-legal tires. She qualified second with a stout 8.75 at 157 mph—not her quickest run, but certainly not slow. She knocked off an even quicker 8.68 at 157 mph during a test hit prior to qualifying, which is slightly off the car’s best run of 8.44 at 165 mph.

The Caddy is currently powered by a
427ci LSX complete with an LME billet intake manifold, MAST cylinder heads, Vengeance custom camshaft, and a Huron Speed twin-turbo kit. Ron had Huron build a custom air-to-water intercooler for the package to keep the inlet air temps down at high boost. Recently, Misty turned to a FuelTech FT600 engine management system to control the engine and handle power management. She manually shifts the RPM-built 4L80 transmission.
Ron recently surprised his wife with more go-fast gifts, first a set of upgraded Precision 6875 turbochargers, and then a new set of RC Components wheels to complete the car’s new look and mid-8-second capabilities. The combination of these parts and the FuelTech’s power management capabilities has the Mowen family looking to run harder than their best of 8.44. Misty didn’t get a chance to do that at Street Car Braggin’ Rights; she went a few rounds in the classes she entered but exited before improving on her elapsed time.
Misty has polished her Cadillac’s classy appearance and is keeping the model’s motorsport heritage intact, thus staying true to the art and science of speed as intended.
