I hear others mention on this and other performance sites of the turbo spool kicking in. Is this something you can hear? I only goose it every now and again and have never heard this sound. The car does accelerate very fast though and all I hear is the nice low roar of the engine. In other cars that I have driven ex, Chrysler turbo, Audi turbo you can hear the turbine spooling even at low powersettings. Is this normal for the S70 Glt?

Thanks
