I'm getting a lot of questions about the cooling of the engine. When I had the idea, I did some good thinking first. I worked out my plans, and asked the advice of some people.
A friend of mine, who worked at a BMW Dealership for over 14 years, told me (without hesitating) I shouldn't be worried about that.
Another friend who audits and revises engines for over 35 years also said it won't causes any problems.
As long as I don't cover up the radiator, and I mount the plastic cap for the airsupply towards the airfilter, there won't be any problem. These are the things that still original, only that I covered the airbox and supply.
About the left and right cover, they will get a better flow now it's all closed. There won't be any turbulence between parts who are underneath. Also these aren't any parts who get warm or so.
What I will do is mount a flexibel pipe onto the whole that's in my front bumper. I'll mount this so, that the air will blow towards the manifold.
If this will help a lot, I'm not sure, but all the bits help...And so there's a use for the whole in the bumper too
I also removed the big rubbers on top of my headlights. These were there to create a nice closing between the lights and the hood once it was closed.
I now took a much smaller rubber so there's room for air to pass there too, something that was not possible before.
Do not underestimate this, at BMW Performance you can buy an extra airfilterhousing witch end up there. So I'm guessing that BMW did some thinking and testing before producing that.
Here's a picture, the extra piece is marking with red.
And if it's does get to hot under the hood, the I'll take my disc, and put a hole in the hood...I'll invent something in carbon fibre to finish it off.
I wasn't serious at the last sentence ... or was I ?
