Having a goal with your racecar is a great way to keep what you do to it under control. There are some racecar projects that start out small, but then grow into a monster that the owner never intended. As a prime example, Jerry Groves originally purchased his CTS-V for his wife with the intention of just doing a few upgrades, but the car escalated quickly into the world’s first seven-second CTS-V.
Groves is the first to admit that the car started out with just a few simple changes, but when the speed bug bit, things got serious.
“We started out just by doing pulleys and bolt-ons for her on the car. Then we decided to do heads and a cam and go for the stock blower record, which at that time was 9.97. She said just leave it alone, but I couldn’t. We added a 100 shot of nitrous and ended up blowing the car up,” Groves says.
After the motor gave up the ghost, Groves purchased his wife a 2014 Z28 and claimed the CTS-V as his own. The car’s new goal was to run in the seven-second zone while still being a street car that he could pick his son up from school in. To achieve this new objective, Groves would pick some amazing parts and people to make the power needed to get where he wanted to go.
The CTS-V went to Gearhead Fabrication to get the roll cage, turbo kit, and other items added to the car. Total Engine Concepts built the monster 420 cubic-inch Chevy Performance LSX-based motor that features a sexy LME billet intake and gets boost from a pair of 76mm Precision turbos. The motor is backed by a TH400 from ATF that’s filled with the best parts to help take the 2,000 horsepower worth of abuse being dished out. Chad from D3 Performance Engineering tunes the ProEFI ECU that controls the luxury beast.
This well-designed combo was able to blast the 4,000 pound CTS-V down the track at a blistering 7.659-seconds at over 181.64 mph with a 1.19 60-foot. Check out this video from BigKleib34 that documents Groves’ record-smashing run!
