Mark, could only hear the engine purring like normal. revs only got to around 3000 and like you said just like sitting in a nice comfy armchair. Going around one or two of the corners I would normally take @ 30 was a bit strange taking them at 45/50 as you heard the mud guards dragging a little, but with an older vehicle I suppose that it not unusual, but it held the road like it was on rails! Seeing the faces of the TT Marshals as you fly past them holding up their fingers letting you know how long you had left before the roads shut was an experience. Especially along one straight, Cronk-y-Vody where it is normally 7 or 8 minutes to home and only having 5.
