I left work late last night and toed it down a nearby dual carridgeway with a mate from work. I floored the accelerator through the gears and about 1/2 way through 3rd, I started to smell a "lovely" burning rubbery smell crossed with that fresh new exhaust smell. I eased off and let him fly off in to the sitance on his own and the smell went in about 1/2 a mile. Any clues guys? If it helps, the engine had only been running about 3-4 mins before.
