JWT managed to use softer springs because its cams are designed, tested and ground to provide the desired flow characteristics, and accommodate the harmonics of the VQ valvetrain to eliminate miniscule profile changes. These changes are often overlooked by cam manufacturers and can induce spring surge, causing valve float at specific frequencies. Next time, we'll bolt on the turbos and install the engine, along with the additional hardware to keep Project Z running on the track. We'll see how close we come to the 500 wheel-hp needed for a fighting chance against the Z06.
