John,
If the circle is tight enough I don't think you will develop high enough
speeds for it to be a problem. Also in addition to just increasing the speed
to see which set of tires break loose, increase speed until the circle
begins to widen. They let up on the gas. If the car immediately turns into
the center (this is all while holding the steering wheel in a fixed
position) it has an under steer tendency. If when you let up on the gas the
tail starts to come around it has an over steer tendency.
Anyway it is a lot of fun to check out.
Regards,
Phil

Subject: TR-3A: Skid pad oil starvation question
I would like to take my TR-3A out on a circular skid pad to measure G
forces and to check for over or understeer. The drill is to drive around a
marked circle at ever increasing speed until either the front tires, back
tires or all tires let go.
I'm concerned about oil starvation. It seems to me, however, that if I
top the oil up and confine my experiments to right turns everything should
be ok, since the intake to the oil pump is slightly to the left of the
engine's center line.
Does this sound safe?
