Progress on the cooling system of the Audi R18TDI
The first real time since September, I have a bit time to continue building on my Audi. It’s still an amazing car. I continued on the cooling system. More precisely on the water radiators. They are insanely big. Much bigger than the ones at the RB7. But considering the fact, that the Red Bull runs 1.5 hrs in Monza by 70% full throttle or two hrs in Spa Francorchamps by 65% full throttle and the Audi runs 24 hrs by 85% full throttle in Le Mans you shouldn’t wonder that the Audis radiators are much bigger than F1 radiators. At the current status, namely the fixed intercoolers and the finished water radiators, you can see the whole mass of the car. It’s insanely wide and voluminous. F1 car’s max. width is 1800mm and 1400mm chassis width. LMP’s are allowed to be 2000mm (tyres and chassis). Finally the engine is fitted to the monocoque. Before I did that, I had to do the holes at the front (for nose attachment) and rear (for engine fixing and engine cover attachment). That was a difficult work. Because of the strenght of my chassis, I had to use a needle, a nail and a hammer. Locating the point with the needle and then hammering in the nail into the chassis. It works extremely satisfactory.
