This sinister-looking C7 Corvette Z06 features sequential gears, gigantic turbo, and spits flames like an active volcanoby Dim Angelov, on
When it comes to modified cars, the main goal seems to be high horsepower. However, having a well-sorted car means building it to send that power to the ground, as efficiently as possible. With this in mind, That Racing Channel (TRC) is giving us a YouTube video of one such car – a sinister-looking C7 Corvette, which may be one of the most well-sorted high-horsepower builds, you will ever see.
The car in question is Matt’s (@MKAV24) 2015 Chevrolet Corvette Z06 that, under the hood, has nothing in common with your average C7 Z06. That’s because under the stock-looking car is a 427 cubic-inch LS-based V-8, built by Borowski. This was done because, at the time of the build, there were no kits available that would allow the LT4 engine to handle the power, Matt was after.
The LS dart block is rated for 2,300 horsepower and has crankshaft and connecting rods by Callies, as well as Diamond pistons, Bosch 210 fuel injectors, Motec M150 ECU, a custom harness, and a lot more. More importantly, it has a Precision 94mm single turbo, which at 40 pounds of boost makes 1,800 horsepower at the rear wheels. However, Matt says they haven’t pushed it past 24 pounds, but they will eventually.
Matt says he’s planning to upgrade the turbo for the Texas 2K (TX2K) event, but even now, his C7 Z06 runs in the low 10 seconds at the quarter-mile. More importantly, it’s capable of beating some highly-modified Nissan GT-R builds and we all know how fast those are. A big credit for the Corvette’s speed must go to the six-speed sequential gearbox from Samsonas, the RPS quad-plate carbon clutch, and the Wavetrac differential.
Matt says it took a lot of trial and error, as well as some broken parts, including a few burnt clutches until the “Vette” got to where it is. Even more impressive is the fact the car is fully streetable and Matt is using it regularly, even though it’s set up for E85 and doesn’t even have a pump gas tune. There is a C16 tune on the car, but Matt only uses it on the track.
Around the 5:07 minute mark, Matt starts up the highly modified Corvette, and, after some fireworks, courtesy of the two-step launch control, he takes us for a ride. Under acceleration, the exhaust, which sticks out the front hood looks more like an active volcano.
Being a streetcar, the C7 Corvette features a full interior. The only notable difference is the sequential shifter and the Motec rotating knob, which allows Matt to alternate between the different maps. Matt explains that setting one is around 16 pounds of boost, which is good for around 1,200 horsepower while setting two is 20 pounds and approximately 1,275 horsepower. The last setting (for now) is at 24 pounds of boost, which is good for close to 1,400 horsepower unless you put C16 race fuel. Then, the ECU automatically cranks up the boost to 40 pounds, which is good for around 1,800 horsepower.
The main issue with the C7 Z06 is cooling. Because of the turbo setup, the radiator couldn’t be mounted properly, so it was relocated to the back. That didn’t work, so eventually, the small team managed to find a way to mount the radiator at the front, in a way that would allow for efficient cooling, regardless of driving conditions.
The pulls, made during the video speak loud enough for the car’s capabilities. Matt says, the car still has more in it and they continue to work on it. As they say “a project car is never finished” and his next goal is 2,300 horsepower. An LS-swap may be common in the world of modified cars, but an LS-swapped Corvette C7 Z06 is not something you see every day.
