On a MINI it would be more like. a "Nodder".
This is what I have been playing with.
IC: FORGE
Background: if you look back at historical posts a critizism was that they sit up rather high.
A local Forge vendor (Minspeed) asked me what I would change about it. So I had them angle the IC (Low infront/high in back). The objective here was to enhance the exit space underneath. All hood materials had to be removed.
I then had this scoop made up, the objective was to create more of a funnel effect. The side pic shows how the scoop tapers towards the rear. The thought process was that this will pressurize the air above the IC sooner or faster thus going thru the IC sooner/faster. It also eliminates dealing with seal leakage.
As you can see it is just tack welded for now, but once I confirm that there are no rubbing issues I will have it welded up.
I don't have tools to produce discussable data but I am finding noticeable differences between left/right horn to the touch. I am also finding that the scoop itself is cool to the touch.
Any way it was fun to make.

Now I have to get my azz going on mine.
it is the WALL you might say . if i had a crashed cooper s with a good hood i wouldn't think twice . i'd just start small and work my way out . the real issue is a design that would work with the cooper . it's not a muscle car . so it'd have to have a european flavor .
I will most likely add a damper but th edesign needs to allow for un damper if this is ever to be produced.

Pretty much what Phil said. The bias is in the forward throw since that is the direction of torque motion. Back is just rebound. I'd lean more to a 65/35 split
