That 4.2 Fsi V8 also doesnt produce claimed power either and suffers from carbon build up in the exhausts which reduces power. A customer of mine had his dyno'd and it was making only 320bhp.

Only 320 bhp? Was that due to solely to carbon build-up or is the engine inherent design would not make full power (like the TVR Griffith 500 "claimed" 340 bhp but never do)?

I thought about an RS4 estate and if there are inherent engine design fault that the engine would not make full power, I'm not going there.

Its just carbon build up. Effects other marques like BMW and Porsche too with dfi engines.

Source for porsche please?

Heard it speculated, never proven.
