Hi

The test with the foam filters is over, they are worse than the K&N.

Image 1 shows the measured value block 032 at the time of September 2020 and there is a small amount of carbon deposited on the inlet valves.

image 2 shows the lambda learning value at which the foam filter 1100 KM were operated. Carbon was eliminated in winter 2020/21

Image 3 shows the lambda learning value after two days of operation with the K&N filters.

1: Partial +5,1% / +4,7%
Image

2: -1,2% / -3,5%
Image

3: +5,5% / +5,5%
Image

The foam filters let through less air and thus the engine needs less fuel and thus less engine power.

Hi

Current value + 7.9% and + 7.0% the highest value ever achieved.
More fuel means more torque and power. :nodder:

Hi

The V8 is a bit critical in the engine's heat balance and there are two thermostats 87 ° -104 ° and from 2010 85 ° -95 ° degrees.
As a Heissland version, there is an additional water pump that is only coupled with the fans when the air conditioning is switched on, so not perfect on the Audi side.

A continuous run of the pump to get the engine oil to the level of the V10 with 100 ° degrees, the 8Z9 pump is used and connected to a thermo switch 87 ° degrees via terminal 15 via relay.

More information will follow.

Hi

Full carbon fiber at 2.1Kg.
A reduction in weight to the series of 5Kg. :rocker:
