Not sure this has been mentioned (or how irrelevant!), but I've been told that
by just getting off the gas, Indycars (and presumably F1 cars) get about a G of
aerodynamic braking from 200+ mph!  I guess I should be able to figure out this
one.  Let's see, 700hp=385000 lb-ft/s.  At 200 mph, this converts to 1300
lb-force.  If at terminal-V, drop that power to zero and you have, in effect,
that 1300 lbs in aero braking.  If the car weighs 1300 lbs, that's a G.

Sorry for the random meanderings...

That's okay!  I can't wait to see your car setups on the 'net! :)

Agreed.  Living in Melbourne, I went to my first GP this year (yes I am
too lazy to go to Adelaide!).  Anyway, yes, I'd say that they seem to slow
down at the seccond last marker on the track.  Gee you really get a feel
for how got these cars are in real life!

Just as un related warning, make sure your film is in your camera properly
when you go to a GP.  Its not fun carring around a really good and heavy
camera all day, getting shots of your mate shaking hands with Katayama
after his engine blew in practice then when you get how the film is
useless!!!!

Have fun.

Why do you think real F1 teams spends over $20,000 each race on brakes
alone this year?

If you've never seen one do this, I wonder if you've seen the things "in
the flesh"? Watching them at Silverstone at the end of the Hanger
Straight as they brake for Stowe this seems sensible, they seemed to
brake at the 50m marker!

Their stopping power is what amazes all drivers testing cars for the
first time apparently - an F3 driver rapidly handles the extra
horsepower and the gain in power:weight ratios on things like
accelaration but learning new (apparently ludicrous) braking points
takes time. We are talking cars weighing a hell of a lot less, and using
carbon discs, if you have an Indycar perspective!

I remember an Autosport interview with one driver, Jan Magnussen or
David Coulthard I think, who said that the difference between F1 and F3
cars braking was of the same sort of order as that between a racing
saloon car and an F3 or Formula Ford car. So, if you're a sim-racer
only, try an ICR2 trip around Watkins Glen (say) and then do the same in
a Nascar. In the latter you probably brake for the first turn at, or
just before, the concrete wall becomes armco - and for the chicaine
(Turns 5 & 6?) you probably brake when the first red marker appears.
Surely you brake a LOT later than this in ICR2? Well.....extrapolate
that further - Indycar brakes are limited to iron discs I believe and
they are a lot heavier than F1 cars aren't they - so probably they brake
in a fashion similar to F3 cars (or worse).....

JJ> Why do you think real F1 teams spends over $20,000 each race on

Don't know if that figure is right, but carbon discs and this other
"cutting edge" technology, etc doesn't come cheap!

Cheers!

  I never raced below ACE level, but from all the posts here I would
say that the damage degree doesn't change.  I hit the wall exitting
turn 11 (the fast left hander before the second chicane) in Hungary,
at 90+ mph.  All that happens is my left front wing is in the air.  No
flat tire, no cut, nothing.  So I guess the damage is constant
throughout the "difficulty" levels.

  Don't know if I followed your explanation there <g> but I'd say it's
not only the aerodynamics that contribute to negative acceleration
(this could also mean braking for some of you GP2 drivers <g>), but
it's also the torque of the engine.  Don't really know how much torque
those V8's have, but having about 890 hp (talking about Indycars) I
can imagine an incredible torque around 11k-13.5k rpm.

  A bit off the topic here.  I remember, two years ago, I rode a
Suzuki 500 bike, normal street legal bike about 27 hp, While going
about 60 km/h I took out all throttle and felt the gas tank pushing
pretty hard but not too *** my "you-know-what" :).  The point is,
I wasn't used to this type of idle torque.  Before I rode a Honda 80
which had a 2-stroke engine.  You let go off the gas, and the engine
keeps on roling...  4-strokes stop compared to 2-strokes.
So I can picture quite a (mechanical) drag created by the engine.

Take care,

Dave.

   I never race below ACE - Phew my heads sooo big  :)
