[Fot] dog box transmissions in SCCA racing

[Bob Kramer]

Thanks Anthony. It took me a while to get around to it but I've now looked
up the current SCCA prep rules. In vintage racing, we have a lot of
cars with non-standard stuff like dog gear tranny's and Wilwood brakes. My
Texas club has a Rules Change process that requires a racer to submit a
proposal including documenting the need. We have approved some items over
the years.  Often the reason is that parts are no longer available, or are
just crap. The problem is that it ends up as an upgrade. Once you do that
for one brand the competition, who didn't ask for or cannot document a need
is now miffed. Some of these improvements result in more HP, traction,
better gearing and create a new weakest link, which soon becomes a rules
change proposal. I'm on the Competition Committee in our club, the one that
works on the change proposals. I'm starting to wonder if we should look at
standardized weight penalties using a percentage of the approved weight
across the board to level the playing field.
