A 560-whp Corvette should make a pretty serious first impression at the Nürburgring. Misha Charoudin’s did, just not in the way anyone wanted.

The heavily modified C6 Corvette had barely started its first track run when the engine cut out, leaving Misha stranded at the side of the circuit. A car built for the Nürburgring had somehow managed to turn its first few moments on track into a tow-truck job.

And that was only the beginning. After the team fixed the problem, Misha got back out, completed a full lap and decided to hear what the Corvette could really do with its exhaust valves open. That worked out too, although the Nürburgring officials were not nearly as impressed by the soundtrack.

The 560-whp Corvette had a lot going on

This was no ordinary C6. The Corvette had a built engine featuring Katech performance parts, NG Motorsport ported and built heads, oversized valves and a Katech everyday camshaft. On the dyno, it produced 560 whp with the exhaust valves open and around 545 whp with them closed.

The rest of the car had been built with the same sort of purpose. It had a custom RPM Transmissions TR6060 with Corvette ZR1 gear ratios, a 3.9 final drive and an OS Giken differential. JRZ RS Pro three-way suspension, Apex wheels, an AP Racing big-brake kit and Endless MA45B pads were also along for the ride.

Cooling was clearly a priority too. The Corvette had a PWR radiator, LGR engine oil coolers, separate transmission coolers and an upgraded high-flow water pump. Misha was not simply throwing a powerful engine into an old Corvette and hoping for the best. There was, however, one rather important mismatch hiding under the hood. The car was still running its original 2006 ECU with a much larger 103 mm throttle body.

The first Nürburgring run lasted about as long as the warm-up

Misha’s plan was not to chase a lap record. The Corvette did not yet have its planned Vallon Alpha aerodynamic package, so this was supposed to be a baseline run to get a feel for the car before making it faster. Instead, the engine cut out almost immediately after he got onto the circuit. That meant the first Nürburgring outing for this 560-whp Corvette involved Misha pulling over and waiting for a flatbed. Not exactly the kind of first lap anyone puts on the highlight reel.

The problem eventually came back to the 103 mm throttle body and the original ECU. The older 2006 unit was struggling to understand the amount of airflow coming into the engine, throwing the car into a situation where the hardware was ready for the track but the software had not caught up. HP Tuners helped connect Misha with RR Speed Performance, which applied a custom ECU calibration to work with the larger throttle body. With that sorted, the Corvette finally got another shot.

This time, Misha went into a Touristenfahrten public session with the exhaust valves closed. The car completed a full lap, although temperatures climbed enough to get his attention. Thankfully, the upgraded cooling system appeared to be doing its job, and the temperatures started coming back down.

The Corvette did manage to pick up one small problem along the way. A cable from the rear fog light came loose and started dragging underneath the car. Luckily, a few people in the car park helped secure it with some gaffer tape. So, after a tow truck and a roadside cable repair, the Corvette was finally ready for another go.

Then Misha opened the exhaust and got banned

For the next lap, Misha wanted to experience the car with the exhaust valves fully open. The first full lap had been completed quietly enough, but there was only one way to find out what the Corvette’s full 560-whp setup sounded like around the Nürburgring.

He opened the valves and went back out.

The Corvette was quick, loud and clearly doing what it was built to do. Misha later described the car as genuinely intimidating without its planned aerodynamic package, saying the lack of aero made it tricky to drive.

Then, near the end of the lap, the Nürburgring had something to say about the noise.

“Too loud.”

That was the end of the Corvette’s day. Track officials pulled Misha over and banned the car from continuing the public session because it exceeded the circuit’s noise limits. Misha took it in good humor, later saying he would keep the valves closed for future runs. He also admitted that the noise was a bit much inside the car anyway.

It was a pretty memorable first outing. The Corvette stalled on its first attempt because its original ECU could not properly deal with the 103 mm throttle body. It needed a tow and a custom ECU calibration, then completed a full lap before a loose cable had to be taped up in the car park.

And after all that, the final problem was not mechanical at all. The Corvette was simply too loud. Misha was still happy to be back on track, and the day gave him a much clearer idea of what the car needed next. The plan was to work on the suspension and add the aerodynamic package before returning to the Nürburgring.

For a first test, it was messy, noisy and slightly ridiculous. But at least the Corvette made it around the track before getting kicked off it.
