Have to disagree there Dave..
This is a Vbox overlay from my 135i DMS Stage 1 and my Revo Stage 2+ Ed30 (both DSG/DCT) at MLR's 30-130mph day. Same temp, same conditons (Golf - Blue / BM - Red).
Over that range I honestly expected the Ed30 to be slightly quicker to be honest. With their power outputs being fairly close but the BM humping an extra 150kgs about, it would obviously make sense. So when I first saw this to say I was shocked was an understatement..
About close as you will get I think..
This is also mirrored at Santa Pod. Both have ran 12.7's, although I feel the BM has anther 1/10 or 2 in it with a bit more practise. This is more down to better traction though..
