Hi Everyone,
Well I am now running full slicks on the track and yes I gained a full 2 seconds as a few people have mentioned is possible. I had no problem with the car. A few others mentioned though , eg Porsches that you need to run a dry sump or baffles to ensure your oil pickup works with the extra G Force generated.
Does anyone know what sort of pickup and baffles the RS4 has. I was running the Oil level at Max and saw no problems or warning. Oil and water temp was consitent. Just want to make sure it is fine.
Oil Sump
I think I found the answer. Can any verify this.
In the more highly stressed high-revving engine, an additional oil-air heat exchanger is used to minimize the oil temperature even at high engine load. This additional heat exchanger is operated in parallel with the heat exchanger via a thermostat.
Audi RS4 Sump
A reliable supply of oil in all driving situations is critical, especially in a sports car such as the RS4. The oil supply system in the high-revving engine was designed for racing applications in which it is subjected to lateral
acceleration of up to 1.4 g. To ensure this, the sump in the RS4 has an additional system of flaps.
Design
Four flaps, whose axis of rotation is parallel to the longitudinal axis of vehicle, are arranged inside a housing. Each of the flaps opens toward the inside of the intake end of the oil pump.
Function
When the vehicle is cornering, the oil flows inside the sump toward the outside of the corner. The two flaps facing the outside of the corner close and hold the oil in the sump intake. At the same time, the two flaps facing the inside of the
corner open to allow additional oil to flow into the intake. This ensures a sufficient supply of oil to the oil pump.
