Pistonheads have got an onboard lap of Mark Blundell's legendary qualifying lap in the Nissan R90CK in 1990. Apologies if you have seen this before, but if you haven't it is truly epic. Effectively the turbo was on maximum boost for the entire lap, the team told him to abort, he went for it instead. Check out the entry to Indianapolis, eek.
