This one is for all the clever people....
I have a basic understanding of the venturi effect. I liken it to squeezing the end of a hose pipe.
My query relates to is there a specific amount of "squeeze" that you put into an air intake pipe.
Also, the positioning of the "squeeze" - I feel it would make a difference (Not to BHP I shouldn't think) as to how close to the throttle body it is.
If it makes a difference the engine in question is a (And don't laugh!!) 1.4 105BHP K-Series.
Thanks in advance
