i held mine to the nuts in 6th for about a mile, on the brakes for about 5 seconds, and back through to 6th and WOT in 6th for another half mile or so, and then another corner and almost a half mile there.
keep in mind this was with stock carbs and no porting
i dont make a habit of doing that though, but i had good motivation to get away real quick :biggrin:
