Im building my mini to use as a fast road car mainly, thats always been the aim, but i am interested in running up the quarter as well, but its only one of the things i want from it, trackdays interest me more really from a driving point of view, but from a building an engine point of view im very bothered about the terminal speed on the quarter as thats the ultimate test for an engine really in terms of power, but the speed interests me more than the time, so im not fussed about setting it up to launch on the quarter just to shave a few tenths off, cause thats where you start wrecking it for everything else.
