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 more power.
Audi made the real highlight in the development of the V10 in the 4S, here they have taken a smaller
exhaust valve, which is 1mm smaller and the plug and play with the old V8 and V10 as well as the RS4 B7 V8.
The engines reach their maximum speed in less time, 20% faster than the old V10.
Exhaust valve old 28mm, exhaust valve new 27mm
Awesome, isn't it ?
