sounds gimickie to me. However, some of the information seems to make sense. On the other hand, with Zenith Stromberg carburetors, and probably SU's as well, I don't think it'd have too much effect. I think this because these carbs have that huge air piston in the middle of the carburetor disrupting the air flow, negating most if not all of the "swirling" action created by the "Turbonator".
Additionally, on the ZS systems, there would be no place to install the thing that would be of any benefit. I mean, the stock intake on ZS equipped Bs runs the air multiple different shaped passages and thrrough several unsmoothed 90 degree turns... You'd have to custom fabricate your own intake to be able to install that thing on a ZS carb, and if you're doing that then you might as well make your own turbonator from scratch.
Whether or not it would actually do anything for certian... well there's only one way to know for sure, now isn't there. /ubbthreads/images/graemlins/tongue.gif
