Really, never heard anyone having problems at 8k. Only heard them explode at 8.5k+. Anyway there is a host of other issues with higher revs that an improved oil pump will not help with.
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.
