To gain 5 seconds by the modification of Brandish I think not.This would mean that if the speed of approach was 180mph in 5sec you would travel 440 yards further from a given point than you would if the old Brandish existed.
Agreed the approach speed to Hilberry will be awesome and this will alter the breaking point considerably but may even slow the mid corner speed of the bend
Still all will be revealed in 3days time
