Dave,
Could you put some description to pictures 5 and 6. Where exactly is that venting to and how did you set it up? Also, can this be done with the R1/2 models with the extra oil coolers?
What are you using for the metal pieces going from inside to outside the car?
Any body else with pictures of engine venting- ghetto or not?
Thanks,
Justin Wade

Of couse this kind of assumes that there is more negative pressure "pulling" air though than there is positive pressure "pushing" its way through the front. (I have my doubts..) Otherwise you are blowing hor air (from the oil cooler) into the engine bay.

Yeah, I did this 4 years ago. Had too much time on my hands and the fender was off of the car. If Rufio ever gets my tail lights 99-spec-i-fied, I'll stick a probe in there and drive around a little bit if you like, vented and un-vented. It's been a while since I've had the twins in there and the single with the turbine blanket runs SOOO much cooler, I'm not sure it would tell as much..
And besides, it's just a little hole. My car, while clean, will never be in a show. It's not structural..

There may be. The concept was that the outside vent is a low pressure area, so would "suck" air. Not yet "proven" but plausable since Mazda expected air from elsewhere (oil coolers) to vent there without being forced into it.

I believe it is proven. Its original purpose was to suck air through the oil cooler by using Bernoulli's Principle (fast moving air along side of the car has a lower pressure than the air behind the oil cooler).
Here is the Wiki:
http://en.wikipedia.org/wiki/Bernoulli%27s_principle
"The pressure reduction effect can be observed by blowing over the top end of a straw with the bottom of the straw in a container of water; the water level will rise in the straw as the flow over the top of the straw increases in speed."

Very old thread, but the idea is still lame.
Notice those big gaps between the engine & engine compartment (you can see the ground)? That's a pretty big hole to circulate air through. While hot "stagnant" air rises. Air flows to the path of least resistance or pressure.
This mod is like cutting a small hole on the wall in your garage to vent the hot air, but you have the garage door open at the same time.
People confuse heat soak with operating temps. In motion, air is circulating through the engine compartment. Plus the engine is not an air cooled VW. So this wont make it run any cooler.
I especially like the pic of the fender liner cut with the screen installed to vent the oil cooler. It would be so beat up after a lapping day I would be more concerned with spinning on my own oil after I punctured it with debris.
