Not in all types of racing. Actually, in some types, the narrower the
better, less contact area, less friction. Take a salt flat racer, for
instance.

Yeah, and bicycle racing.

Though it doesn't apply much to boat trailer tires, the heat
conductivity of the gas would work against tire cooling in the case of
race cars and aircraft since it would serve to increase the rate of tire
heating in heavy brake application. Many aircraft tire failures are due

Of course it all depends on the type of racing. During most racing like
road racing, twisty corners, etc, heavy braking is applied but for very
short durations. Superspeedway racing, not at all.

Are you really trying to say that on superspeedways, they don't use
brakes at all? That's pretty stupid. They actually use brakes as
opposed to letting off the throttle, trying to keep the enginer RPM's
up. It takes forever to get those restictor plate engines back up to
speed. They do, however, use completely different brake setups,
smaller rotors, pads. These smaller, thinner rotors will get quite
hot, quite quickly.

Sorry to dissapoint you but at NASCAR restrictor plate races like at
Talladega and Daytona, the driver will almost without exception have
the gas pedal to the floor and not touch the brakes all day.

Pure horse****!!!!! They do, indeed, keep the throttle wide open, but
they DO use the brakes, and quite a lot. They use the brakes as
opposed to letting up on the throttle when drafting, to avoid loosing
engine rpms from what is commonly refered to as "lifting". So, to say
that they "not touch the brakes all day" is, again, false.

As usual, you need to do a little more research. But as usual, even
when you learn that you're wrong, you won't believe it and try to put
some sort of spin on it to avoid admitting you don't know what the hell
you're talking about.

You are an idiot!!! You don't know a damned thing about superspeedway
racing, if you think that they don't use brakes. What an idiot. Pure
and simple. Jeez, if you even ever bothered to listen to someone like
Benny Parsons, or Daryl Waltrip, and on and on, when at a
superspeedway they almost always mention using brakes as opposed to
lifting the throttle. It is a VERY common practice.

You may be listening, but as usual you don't understand what they're
saying. Yes, if they have to slow down they use the brakes. Of course.
It's just that for 99% of the race, they don't have to slow down.
Unlike other types of racing, superspeedway restrictor plate racing does
not require the drive to brake going into any corners. It's flat out
pedal to the metal racing around the entire track. The only time the
may need to touch the brakes is to avoid running into someone else and
to come into the pits.

They even
tape up the brake vents for more downforce since there's little need to
cool the brakes.

Actually, almost all teams don't even use brake ducting on
superspeedways, if that is what you mean by "brake vents".

They don't use brake ducting because they don't use he brakes. If they
used the brakes "quite a lot" as you claim, without any ducting, then
Rick would be right in that the brakes would melt the tires.

No, idiot they don't use ducting because the straights are long enough
for the brakes to cool.

Not if they used the brakes a lot without any ducting. You have no idea
about the aerodynamics of race cars.

Bull****. You idiot. The rotors are vented. You've never been close to
a stock car, by evidence of your crap. You'll hear people like Daryl
Waltrip, Benny Parsons, Wally Dahlenbach, etc. talk about using the
brakes as opposed to lifting off of the throttle at least once during
every restictor plate race that they commentate. It's very simple, but
I'm sure you wont' understand. You use the brakes as opposed to
lifting the throttle because if you keep the air/fuel mixture pushing
through the restrictor plate, the engine comes back up to speed much
quicker than if you lift the throttle. Plain and simple, and any idiot
that knows anything about racing knows this.

That's the exact opposite from short track and road course races where
they use the brakes so much that they need blowers to cool the them
since the vents don't provide enough cooling. They use a beefy braking
setup for those races since they have twice the power available so
there's much more to overcome braking losses, and they really need the
brakes.

The "beefy" brakes are because they have to slow the car from say,
130mph in the straight at Bristol, down to 60mph in turns 1 and 2, in
the shortest amount of time. It's all about being able to hold that
130mph until the last possible moment, slamming on the brakes until
the car takes a "set" (meaning it goes from pushing, or understeer, to
loose, or oversteer.), then being able to get back into the throttle.
Of course, I'm sure, you are an expert, as always!!!!
Oh, and your Nascar tire diatribe is wrong, and stupid.

You're too funny. Are you sure you're not Jax?

Hope you are getting it now, but I doubt it.

Your understanding of engines is just as abysmal as racing.

Steve

Haahaa!! You know more about stock car racing than I do?? Yet you
didn't know until this conversation that in restictor plate races,
they use the brakes as opposed to lifting the throttle??!!!
bwaaaahaaa!!
