Wow -- all your cooling is through a ~4" round port? Is the rest of the cooling tract smooth and ducted? Where is the exhaust flow going?

The Lupo's 1.2 TDI is so effiecient that it barely stays at operating temperature. During the winter months the car uses electric heating elements for cabin heat. (Saw a link somewhere, I'll post if I find it.)
EDIT (02-10-2011): Here's the link: First Drive: Volkswagen Lupo 3L TDI

Fuel consumption as low as this leads to a problem in colder months: Not enough fuel is burned to provide effective heating for the passenger compartment. Volkswagen planned ahead though with an electric auxiliary heater that can pick up the slack where the standard system can't.

yes that is more than enough cooling for my engine. Not yet its not ported/tunneled through the hood but it will be. Exhaust come off behind the left front tire... We can continue this in my Lupo thread http://ecomodder.com/forum/showthrea...-2l-18235.html |

I have yet to see any mirror that I truly like. I think that everything is going to leave some turbulence along the sides of the car. It would be interesting to try to find a way to design something at mid window which would fold flat against the window glass. I say mid window because small mirrors are more effective if they are close to the eyes. All this just might be impossible dream, but what is brainstorming good for otherwise ;-)

Some cars are fine-tuned to have the external mirror inside a pocket of turbulence, or at least partially inside. Folding it allows the outer edge to hide inside that pocket.
Tuft testing would show which car/mirror combo would benefit from folding.

To folded mirror I would add small convex mirror to the tip that would work when the mirror is folded to be able still to see  . |

eBay has reasonably well streamlined motorcycle mirrors which fold, cheap.

I used a small piece of aluminum cookie sheet to make a bracket at the correct angle and cemented it to the mirror glass near the hinge so it gives me a wide view when the mirror is folded. I stuck it on the glass with clear silicone sealant so I can hopefully remove it if the need arises.
