Suggestions for Velocity Stacks?

SouthArk370Z

I just don't see velocity stacks doing much good. The longer/bigger the intake/manifold system is, the less good velocity stacks do. If they were mounted mani->TB->MAF->VS, without all the duct work, it might do some good; on a modified factory setup, not so much. While the bell of a VS can give some very small gains, the VS's main function is to tune the intake/manifold. By the time you get from the heads to the air intake, there's not a lot you can do to affect the tuning significantly (without major mods).

Velocity stacks are great for small carbs/TBs with short ducts/plenums/manis but aren't going to do much for a more-or-less stock 370Z setup.

But I'm no Engineer, so YMMV.
