A guy I know put a vortex on his GTP and I just laughed because when you think about it, the air is all going the same place through one port, so whether its smooth or not I wouldn't think would matter.
Turbulence does matter. You want as much air available for the Blower to compress, right? Is the pressure higher or lower if the air is turbulent? The more laminar the flow is, the more can move in the same direction. Turbulence is bad, no matter how you look at it.

Exactly, you definately don't want any turbulance. You know those tornado things that are supposed to "give the engine a better air-fuel mixture." Well Zooomer installed one of those on a GTP on a dyno and it dynoed a 1/2 horsepower loss from it. So that right there shows the that turbulance doesn't help it any at least.

Right on the money, Shawn.

The tornado (or Vornado) actually works in the right application......by that I mean a Carbureted engine with a traditional intake manifold. The swirling air tends to turn corners better, especially in an engine with unequal intake runner lengths (V8'* being the worst for those that are following this).

The runner design and fuel injected technology built into our engines precludes everything in the paragraph above.

We all know the L27 and L36 love laminar flow, but some are under the impression that since the rotors of the Eatons disturb the air anyway, it doesn't matter. The whole point is that you have to get the air TO the Eaton in the most efficient manner possible. The most efficient is the least, or most gradual bend possible, in as straight a pipe as possible. A cone filter is the best thing to go with this.
