Reverse/remodell yoour cooler ducts !
You must put the smaller area at the front in order to use "vacuum" effect.

are you serious with that I bet thats just because lack of space or something other stupid thing...

I'm 100% serious, think about hi and low pressure areas with these two ways of duct design.

I don't see how that would work to be honest ?

My idea was to stop any air escaping under the intercooler, the top section is to stop it goin over the top. So it will work as a ram air system, surely, more air the better ?

A small opening like the one in your link will allow in a smaller amount of air, by the time it gets to the intercooler it will have slowed down due to it filling a larger area.

Surely you could compare blowing into a funnel, if you blew an amount of air through the small end you would hardly feel it at the large opening. If you could blow the air into the large opening, by the time its been compressed into the small pipe it would create a quicker air flow?

I know it looks weird but all that is 100% incorrect ! :wink:
When you have small opening + large area you will notise hi pressure at the front and low pressure at large area zone. This will incease speed of air --> amount ot air per minute.
If you have big opening and small area - you have low pressure ao the front and hi pressure at small area zone. I bet at some speed (hi enough) you will get some air just standing there - not moving and not cooling anything.

When i get the time i will make another cowling and test your theory my friend. I'll get a temp gauge, fasten it to the intercooler and let you know the results ...

Actually two T-sensors (ambient T and at the intercooler).
For correct measurement.

PS: This is not my theory, I just read it :wink:
