further progress on the cooling system of the Audi R18TDI

Another few words on my work on the cooling system of the Audi:

Since fortunately a guy on f1technical.net called my attention on an underbody regulation, I strived towards to eliminate an almost fail of me. The point is: The underbody’s outer 500mm area is regulated to an angle of 7 degree (messured to horizontal) upwards (see pic). Because I did not consider that at the manufacturing of the water radiators, I had to cut them down a bit. The cutting was done by a saw. With a scalpel or a scissor I had no chance. That are the problems of my high rigid method of construction. Well, it’s actually not really a disadvantage. If the radiators aren’t that rigid, maybe I would not be able to cut them down without any damage. To cut a long story short, everything went brilliant and the radiators are now fitted to the chassis and supports now the angled underbody shape. Additionally, I finished the water cooling circuit. The first lines of the charge air circuit are also done.

After I recognized, that I had no chance with a scissor, a scalpel or with sandpaper, I took a saw and raged. 😉


Was bit a tricky work, because I had no vice, so I had to fix the radiator by hand.


After I’ve won the fight…


Here’s the current standing. You can see a part of the water radiator suspension and its lines leading into the inside of the motors V.


Another closer look to the cooling lines.


The inside of the V isn’t correct. This picture Click appeared after I’ve finished the inside.


The cars underside. Not completely detailed, but the underbody will cover this. I guess I won’t make the underbody removable on the finished car.

My name is Paul Bischof. I’m a student in mechanical engineering at the Technical University of Graz in Austria, expected finishing in February 2016. Since I was eight years old, I am building model planes out of paperboard. Since 2004 I scratch (that means building without an assembling set) Formula 1 and sportscars in 1:10th scale. The average time I need for such a car is around 400 to 700 hours within 4 to 8 months. One car has around 3500 up to 5000 single components. On this blog, you can take a look on my work and later, after my studies, hopefully you can see me in Formula 1.
