The only experience I have with the roots is with the Stillen SC kit on the Pathfinder. I don't think the blower was out of its efficiency range up top, but I could be wrong. The Pathfinder didn't have a high RPM redline, so it shifted around 6k. I just didn't notice it jetting the RPMs from 4500-6000 nearly as quickly as the Vortech blower did on my G35. Maybe the TVS was running out of steam up there? :shrugs:
