Hi

Let's see if this carbon / aluminum anti roll bar can be installed.
3.17 kg is its weight for the front axle.

Hi Shortly before the start of the season there is a new diffuser. The old diffuser from 2013 was too aggressive for me and the current one is optically very close to the GT diffuser. New https://www.imgbox.de/users/speedrs4/IMAG6286.jpg old https://www.imgbox.de/users/speedrs4/DerArsch.jpg Tom

Hi New year and let's go, further modify. I've heard that filters with a foam cover should be better than series and I'm interested in whether they're better than my big K&N. The test with a vacuum cleaner was 1 to 1, both of which had a pressure of 0.01 bar generated. https://www.imgbox.de/users/sp...

Hi Removing the air conditioning compressor is too much work. Remains where he is. The V8 has parts that can be replaced by lightweight V10 parts. There are the hoses on the cooling water box, inlet and outlet made of aluminum from the V10. V10 https://www.imgbox.de/users/speedrs4/Nachlaufrohr.jpg V...

Hi I made the decision to dispose of the air conditioning this winter. I haven't used the air conditioning for years and thus the weight of the R8 is reduced by 10-12 kg and the loss of power due to the air conditioning compressor, which is always idling, is eliminated. https://www.imgbox.de/users/s...

Hi

It is quite a sensation that this motor has over 600 NM torque, 679NM to be precise.

The torque barrier was found and eliminated.

Hi Here is something about air filters made by an automobile club. Unfortunately for you in German, but can be read easily with a translation machine. It is shocking how bad the foam filters perform in terms of dirt permeability. My finding coincides with this test. https://www.adac.de/rund-ums-fahr...

Hi

The new valves have the same seat angle as the installed valves. The new valves, lapping / grinding done.

Tom

Hi And now something that the RS4 B7 drivers might be interested in. On the R8 V8, the intake valves were switched to a thin shaft from 2010. See picture 1. The advantage here is that there is less carbon on the valves due to the higher temperature. The further advantage is a better passage and thus...

Hi There were already flooded engine control units because too much was cleaned with the high-pressure cleaner. Here is the solution with a rubber seal as a rain gutter for water. Place shown with red arrow in the picture where the water can penetrate the coupe and the solution in green. https://www...

Hi

1640 Kg without driver full tank.

The weight in the picture is with driver and half full tank.

Hi

After replacing the wishbones, the question of the wheel load arises in detail.

I think that looks good, slightly higher in the back right and good.



Tom

Hi

The V10 from the 4S R8 has new ignition coils and new ignition plugs.

These can only be better than the old parts.



Tom

Hi

This is about the higher delivery rate of the V10 fuel pump in the V8.

Because of its age, I don't trust the V8 pump much anymore.

She served reliably for thirteen years.

Tom

Hi

At Happyparts there are V10 fuel pumps for little money ( 107,- Euro ) and had to be bought
