The tornado is NOT a venturi. It's a bunch of fins stuffed inside the intake tube and is more restriction than anything else. The way i did it there is nothing in the normal path of air flow (well almost nothing, just a very little on the edges) So In this application I have the benefit of the venturi which if nothing else will get rid of the turbualnce as well as the benefit of causing the air to twist. which IMHO works. Others would disagree.
First I opened up the venturi and drove for a couple weeks and noticed an expected difference.
Then after a couple weeks I installed the fins which is when I really noticed the difference in the 3-5000 rpm range.
So what Joe said about losing a little in the low end and gaining in the high end by opening up that venturi makes sense. But according to his schooling (which I do trust) what doesn't make sense is the power gain with the fins.
I don't know, maybe someday I'll get another venturi and open it up like this one but without the fins and then compare the 2.
