Ref: "should"
It is instructive to type define:should in Google's search
bar, and notice that several of the definitions that come up
are from legal codes and engineering standards - and that
"should" is defined as being advisory, not manditory.
Thus according to the rulebook, there is NO maximum speed
limit imposed. With no imposed maximum speed limit, there
can be no protest.
The observation that the only way to make courses slower it
to make courses tighter is accurate, as are (less Jay's
typo) the calculations to work out maximum corner radii.
What is innacurate are the G limits. Modern R tires on
concrete generate 1.3-1.4G sustained and transient peaks in
excess of 1.7G - cause that's the Talon's performance
envelope with 285/18 A3S05s. I suspect a C5 on 335 series
tires may even be slightly larger.
Braking and launch G slightly over 1.4, sustained
acceleration around 0.8 (power limited, I was only making
350 HP/380ft-lbs peak)
Modern SS cars should be in that ballpark.
At some point though, steering dynamics (like the quickness
of the steering rack) will start to dominate over peak
availible G. The Talon was like that, in that it wasn't
physically possible to turn the wheel fast enough from side
to side to reach peak transient G in both directions and
still make the gates (at least with the 275/17 A3S04 -
changing to the shorter sidewall 285/18 helped that a lot)
Peak G drops quite a bit depending on surface construction
and conditions. Dirty or wet asphalt drops G peaks by a
couple of tenths or more.
