[Fot] Why is the TR250K so fast?

[Chuck Arnold]

I got to examine this car in Seattle at a track day once.  Saw it on the
track first and did not know what it was.  Saw it in the pits and took a
look.  Was blown away when I saw it was a TR6 engine.  What really was
impressive is that, as I recall, it has a belly pan giving it good airflow
underneath.

Now that Tony Garmey has won the Kastner Cup, I hope he will join in some of
our FOT discussions.  He is a member of FOT is he not?  If not that is a
nomination needing to be made -- and Bill Hart also.  He owns that car and I
think he drove a Tr powered Lister in the event.
