Theoretical volumetric efficiency numbers:
LS1 at 5,000 RPM: 501 cubic feet per minute
LS1 at 6,000 RPM: 601 cubic feet per minute
VQ37 at 7,500 RPM: 490 cubic feet per minute
2JZ at 6,800 RPM: 360 cubic feet per minute
So assuming even a slight bump in volumetric efficiency for the VQ over the LS1, you are in the upper operating ranges of an LS1 and 25% more than a 2JZ
