1. Poor stock oil pickup for track running - major oiling issues in high g turns
2. VQ37 heads with VVEL run very hot especially at higher RPMs. Hot heads not good. Especially when you run RPMs beyond design spec.
There have been quite a few failures due to running 8k rpm. Raising the redline is playing with fire. It's not worth it to gain a few hp.
