Re: New S6

It probably very possible to make 400bhp out of the engine from the A4
5 valves engine. The A4 Super Touring Car uses a 16valves 4 cylinders engine 
even with a catalytic converter makes 300bhp, it not even turbocharged. If
you find the latest issue of Racecar Engineering volume 6 issue 2 they have
a very detail article about the A4 Super Touring Car. I guess if they can
make 300bhp out of non turbocharged engine then it's very possible and
easy to make 400bhp out of the same 16valves or the latest 20valves 4 
cylinders engine with a turbocharger. Remember the 4 cylinders turbocharged
BMW F1 engine from the 80's which make in excess of 700bhp? I think all 
the super touring car's engine i.e. Vauxhall, Renualt, Volvo, Ford, BMW, 
Honda, Toyota and Audi are all normally aspirated 2 litres engine with
catalytic converter and muffler and they all produce around 300bhp. I think
they are all 4 cylinders with the exception of the Volvo which I think has
a 2 litres 5cylinders smaller than the 2.5 litres in the 850 GLT that are
being sold in the US.
