Never been 160 on 4 wheels only 2, a couple times I have lifted my head off the tank to check my mirrors and had my head not perfectly strait, feels like its going to rip your head off.

 

yea if u stick ur arm out of the car with ur plam facing forward at 160mph you will dislocate your shoulder.... or possibly break your arm.... but hey 160mph couldn't flip a car i mean Newtons laws dont apply to anything with four wheels right?

 

Oh yeah, very easily... just like sliding a car at 15 mph is enough to roll it in the right circumstances. But if I somehow could get my Neon going 160 mph, even as light as it is... there is no way I'm going to spin and roll out of control just by putting the damn window down. I've done enough CAD and conceptual stuff to know that models must be fine-tuned to become accurate... and the only way to do that is to look at it through common sense. I went 160 mph on an open road once... and will never do it again voluntarily... no one can argue that and call it smart. But anyway, just opening the window would not be enough to do it at 160.

More realistically, I'd be afraid of a deer walking out in front of me in a Neon at 160 mph... now that's some very realistic fear (oh yeah, except for the 160 mph part ha ha).

 

Putting a probe for your low pressure gauge
in the 'plenum' just below the windshield
(where the vents get air)
might yield some interesting data.'

On 'blunt vehicles' this area has the highest
'stagnation' pressures'...higher than in front of the grille.

On highly aerodynamic vehicles the area in front of the grille
will have the higher stagnation pressures.

The Neon has got a pretty good Cd...maybe 0.33

If you want to see some 'eye popping' pressures
place a probe just above the top of the tire
with the opening facing forward...here the air speed
is a surprising twice vehicle speed.....due to
'cycloid' tire tread motion.
