hi guys, whilst driving home tonight i accelerated away from a junction as normal, (no sillyness as these are twisty country lanes) 1st gear was fine 2nd gear fine till the boost came on and "BOOF"a small cloud of normal coloured smoke along with a 8-10ft patch of what appeared to be soot left on the tarmac, followed with no accelleration at all. there are no warning lights on dash and the car doesnt smoke but i cant hear the turbo spooling up now. any ideas??
