You heard it first here: They are now leading into the fin chimney
5.8.3 The cross-sectional area of the turbine tailpipe exit at the rearmost point of the turbine
tailpipe must lie between 7500mm2
and 14000mm2
, and the total cross-sectional area of the
wastegate tailpipe exit(s) at the rearmost point of the wastegate tailpipe(s) must lie between
1590mm2
and 2375mm2
. If there are two wastegate tailpipe exits they must be equal in area.
5.8.4 The last 150mm of each tailpipe must in its entirety :
a) Form a thin-walled unobstructed right circular cylinder with its axis +/- 5° to the car
centre line when viewed from above the car and between 0° and 5° (tail up) to the
reference plane when viewed from the side of the car. The entire circumference of each
exit should lie on a single plane normal to the tailpipe axis and be located at the
rearmost extremity of the last 150mm of the tailpipe.
b) Be located between 350mm and 550mm above the reference plane.
c) Be located no more than 100mm from the car centre line.
d) Be positioned in order that the entire circumference of the exit of the tailpipe lies
between two vertical planes normal to the car centre line and which lie between
170mm and 185mm rearward of the rear wheel centre line.
5.8.5 There must be no bodywork lying within the right circular cylinders which :
a) Shares a common axis with that of the last 150mm of each tailpipe.
b) Have a diameter 5mm greater than each tailpipe, starting at the exit of each tailpipe
and extending rearwards as far as a point 600mm behind the rear wheel centre line.
c) Have a diameter 30mm greater than each tailpipe, starting 2mm rearwards of the exit
of each tailpipe and extending rearwards as far as a point 600mm behind the rear wheel
centre line.
