I wonder what are the difference between the S5 354 hp 4.2 V8 FSI engine and the RS4 420 hp V8 FSI engine.
The new S5 engine have 440 Nm of torque and the RS4 engine only 430 Nm of torque.
Is it possible to tune this new S5 engine to 8250 rpm and 432 hp.
Or are there more changes made to the RS4 engine to get 420 hp out of it.
Hans.
