Maybe JdF's local replay showed a too high speed. John Prather says his
setup can't go 220 at 70o Clear without draft. He says it seems to maxx
out at about the same speed where the setup I uploaded maxxes out, and
only go a mile or two faster under specific circumstances (entry into
Mulsanne perfect, and later in the race).
Regarding the speed increase later in the race, I wonder whether Papy
still models this 'tempest in the bowl' thing, where the fact that the
air starts rotating with the cars in an oval after the cars have been
driving round and round for a while makes them faster by reducing drag.
I think I remember Papy modelled this in a version of Nx (although I may
be mistaken), and since I can't imagine they had a different way except
to decrease drag after a certain percentage of laps into the race, this
might happen on roadies as well. Incorrectly but explainable?

Well John, I appreciate the "words of support" but, i've never gotten
near 220 on mulsanne at 70/clear with no draft. I remember that race
though, it was fun :). Anyway, I found the replay of the lap in
question (the 3:03), and my max speed on mulsanne is 216. I know
earlier in the race when I was drafting with you and some other
drivers I may very well have hit 220 but not solo.

Have we determined if someone saved that replay? I've gone through
the stuff I saved and I don't think I have that one...

Yes, I exaggerated a bit-I guess it >seemed< like your
straight speeds (217-I just checked) were that quick, when you
are nailing almost every turn. :-) Wish I could get out of the apex
like you guys do (I invariably spin and/or my wheel starts
oscillating like mad-let me guess you don't use FF...).

Yes Hal. I was messing about yesterday and by setting the rear shocks like I
said I got 118 and a back-flip. Give it a go ;)

Probably not. I just don't have the time or the patience to put in a lot of
time practicing a track like that. Get bored quickly. I honestly don't know
how people can run some of these tracks as much as they do. I feel like I've
eaten too much candy when I spend too much time practicing. :-)

Limerock...sub 50 second laps in TPTCC/nr2k3 spec. I wonder what the ETCC
cars would do there?
