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!! |

Go spew your crap on the racing newsgroups and they'll laugh at you just as hard as we do here. Steve |
