John,
Is this for another car you are building? Your Honda has a belly pan and
I would think there would not be an issue with step pan design.
Page 42 in the 2005 rule book gives a description of the step pan. From
what it says, I would assume that the front of the pan could be either
at a right angle or at 45 degrees.
It would seem to me that the 10" would be at the nearest point.
The step pan cannot be lower than the bottom of the frame rail, but
could be on top if you desire.
These rules are to keep a non-belly panned car from getting the effects
of a belly pan by step pan design.
There are lots of tricks that help the underside of a vehicle, which in
my opinion is more important that the top side. My '29 roadster was
designed to have a very clean underside. The engine was mounted high.
Even with a wet sump, the bottom of the oil pan was just below the
bottom of the frame rail. I had the fuel tank mounted on a flat sheet of
metal that was attached to the bottom of the frame rail in front of the
engine. The step pan began at the firewall on the bottom of the frame
rail and extended back to where the rear "Z" in the frame began. The
rear axle was above the bottom of the frame rail. The only thing that I
see in the rules that would have disqualified the '29 is the 45 degree
bend at the rear of the pan and the fuel tank mounting.
How is your project coming along?
