When the rumors of the C8 Corvette Z06 using a Flat-Plane Crank V8 engine were officially confirmed, the naysayers came out in force with all sorts of predictions about the 5.5L engine not being able to handle the vibrations inherent in the FPC design.

Chevy’s powertrain engineers led by Jordan Lee and Dustin Gardner were undaunted despite the problems they saw that Ford was having with their own 5.2L Voodoo V8’s flat-plane crank design. Early on in the program, they bought a used FPC engine from a Ferrari 458 and did a complete tear-down to learn the secrets of one of the most powerful naturally aspirated engines made.

The first real-world test came with an engine variant dubbed the LT6R that would power the Corvette C8.R race cars. These engines provided thousands of hours of real-time feedback for the engineers and while also putting to bed the fears that vibrations from the flat-plane crank would tear the engine apart. Engineers spent countless hours working to incorporate lightweight components for their moving parts to better manage or reduce vibrations.

Having said all that, we know that GM has said that the LT6 vibrations are part of the experience of driving America’s newest sportscar, but the question was how much of these vibrations remained now that the street versions are in customer’s hands? Well, not too much, according to this quick test performed by a member of the MidEngineCorvetteForum.com.

John006 took delivery of his 2023 Corvette Z06 Convertible last week and did a simple test with a glass of water to show us what kinds of vibrations we can see with some engine revs. Raising his HTC top into the service position, John006 placed a glass of water on his engine cover and then gave it some revs. He didn’t get close to the 8600 RPM redline with these revs, but as you can see, the vibrations were minimal.
