Re: aerodynamics question

Unless you've got access to a wind tunnel (we wish), a coast down test 
is the best way to determine your drag coefficient.  The Robert Bosch 
handbook gives a good description of how to do this.  I recently bought 
a GTECH accelerometer gizmo, because I'm too cheap to buy a real data 
acquisition system.  I wonder if it could be used to do an accurate 
coast down test.

While we're on this subject, does anyone know whether a hardtop would 
reduce drag on a TR3 or TR4?
