I know how you feel m8, I done almost the same thing at Brands Hatch, apart from I was in 4th at maximum revvs going into 5th and I put it into 3rd.............end of the day for me, cracked the head in 3 places, bent 4 valves and cracked the valve guides, knackered the turbo, but I have got her up and running again, better than ever before, just in time for Castle Coombe on 10th July.
Cheers
