Re: vr velocity stack It increases velocity, but reduces flow. Reducing flow = bad!
You want to flow as much air into the intake as possible, not as fast as possible.
Just like the "Tornado" or whatever it was called, it is BS.

Re: vr velocity stack all it accomplishes is covers the idle and pcv inlets in the tb mouth.. you can do this yourself with some epoxy putty, sandpaper and a drill and not decrease the size of the tb opening overall.

Re: vr velocity stack i here you all...
i really do...
but my question is have any of you seen dyno results????
i was thinking the same thing as you till i looked closer at the design....
the smallest opening in the tb stock is still the smallest part after the part....
so how can it be a restriction???
