You won't notice an impact on the quickness of revving through the power band. What you will notice is that the RPMs jump from mid-range to redline VERY quickly. Lower down in the RPM range, you won't experience lag, but you will feel a very slight 'bog'. At least, this was my experience with the Vortech blower. With the roots type blowers, I notice zero lag and no real difference in RPM building even up top.

Easy to make a roots blower drop off high also - just push it beyond its efficiency range. I pushed the old M112 to its limits and beyond years ago before swapping to a Kenne Bell.

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:
