Your data shows that you should have a nice, stable ride.

Subject: My Car Data from Maxton
Okay I promised I'd report what we learned at Maxton with the
potentiometers
and downforce numbers...
Tonya and I have just got done doing the initial calibrations.. and
here's
what we know happened...
The Rear of the car has 400lbs of downforce at 200mph and the Front has
100lbs...
We have some rules of thumb now to evaluate the data... basically it's
measured in volts from 0.0 - 5 Vt.. but the pods all start at a given
voltage.... an increase in voltage means the pod is decreasing in lenght
which
equals downforce... one tenth of a volt equals one tenth of an inch
which
just happens to equal 100lbs of downforce...
These are truly rules of thumb but it's within 5% of the exact perfect
number.
at anytime with the information we just gathered we can get a Perfect to
the
pound number.. We literally added and subtracted 100lb increments of
lead to
the car as well as increased the altitude in tenth inch increments and
recorded pod readings....
There were some other interesting things we noted... like you can watch
the
rear suspension work and the anti roll bar do it's thing... all very
easy to
see once you understand what your looking for... LOTS more to learn
from
this...
Keith
