Sorry, meant to type SC's work better (not best) than turbos low down.....
SC is driven off the crank, so has positive pressure much sooner than an exhaust driven turbo (i.e. straight away)...although see what your trying to say about exhaust gasses.....reckon I'm right and you're wrong
Agree with Martin too, drove a mates G60 and was totally underwhelmed, lol.
