    Yeah sorry I should have included a whole treatise on responsible concealed carry to preempt the nitpickers. Anyway, I am aware of the distinction between shooting in defense of ones life and ones property.

    I would never even reveal I had a gun unless I was about to use it and then only in defense of my life. As for someone who asks me to give them my property, I just tell them to "fuck off." However, most robbers usually pull a weapon and then make their demands, so that leaves you back at square one, protecting your life.

    Anyway, I'm not likely to encounter such problems anytime soon since carjacking has pretty much died off in Florida (concealed carry to the rescue) and I dont travel on public transportation at this time. Pretty much burglars are my only concern and not much of one at that.

    I dont own any guns that lend themselves to high survival rates. The weakest pistol round I shoot (.40 SW) is more than strong enough to incapacitate someone with a single shot. If I shot him with a softnosed rifle bullet, it would probably go through him, but whatever percent of 3000+ ftlbs of kinetic energy it leaves in his torso will still be way more than enough to throw him into shock and probably kill him.

    Consequently, the burglar will not be suing for lost wages because he will be entirely deceased, like that parrot that john cleese bought.

    I would personally never want to have to shoot a burglar or anyone else, but if someone is sneaking around in the dark in my house they have already crossed the line. In florida you dont break into a house without expecting to catch a bullet, so I would expect anyone doing so to be fairly desperate or dangerous.

    In theory yes, in practice no.

    The tire is not a perfect cylinder, nor is it solid. It is usually deformed to one degree or another. This is especially true with slicks that rely on air pressure to maintain sidewall rigidity. A heavier car will require more air pressure to maintain the appropriate shape in a corner (too much deformation and the tire rolls over onto the sidewall or rim, which have no grip). This has the unfortunate side effect of giving it less grip since it now has a smaller contact patch and reduced flexibility between the rim and the contact patch.

    The tire is not parallel to the road (camber) nor is it rotating in a direction parallel to the direction of the car (toe). When turning, the front wheels will gain additional camber as the wheel is turned. All of these details are designed to sacrifice straight line grip for cornering grip. All of these angles will affect the coefficient of friction of the tire.

    The real proof that increased downforce kills off CF is weight transfer during cornering. The more weight that transfers from one side of the car to the other, the more download is put on the outside tires. However, since the CF keeps decreasing, the increase in grip on the outside is less than the decrease on the inside. And the car loses grip. This is also why stiffening the front shocks of my miata allowed me to brake harder- less weight was transferred off the rear wheels and onto the front, increasing the overall grip of the car. See, not linear downforce vs grip.

    If you really care about this stuff in anal retentive detail (as I obviously do), I suggest the "Going Faster" book that skip barber sells. Very good racing technique book that also has details on suspension and tire stuff. That and a couple of long track days really helped my driving a lot.

    Do the math yourself. A lotus street car made from steel is VERY VERY different from an open wheeled race car made from composites. An fully fueled exige weighs about 1700 lbs [b]without[/b] driver. We will assume a small driver of 150 lbs, for a grand total of 1850 race weight.

    A formula one car is regulated to a minimum of 1287 lbs race weight (including driver and fuel) and can generate 1287 lbs of downforce at 100mph. This is far less than the cars are capable of- the rules limit them to this by forbidding certain underbody designs. At 200 mph the car will generate over 5000 lbs of aerodynamic downforce. Speed doubles, downforce quadruples.

    Lets see, that will give the car over 6000 lbs of weigh pushing down on the tires, which are extremely sticky dry weather tires. Such tires on lesser cars could easily generate 2g of skidpad. Furthermore, the vehicle itself only weighs the aforementioned 1287 lbs, so you can imagine how easily the car could generate 5gs of lateral force under the right circumstances.

Others have done it.

    The problem with most cars hitting 250mph is gearing. With the exception of the large V8s with the crazy long highway cruising gears, most modern cars seem to top out around 150.

    Tire grip increases with weight, but it is a log curve- the more you increase weight, the smaller the increases in traction are. Since each increase in weight also increases the mass, the tires have to do more work to change the direction of the car. Thus, heavy cars tend to develop less and less traction than lighter cars.

    Adding downforce increases the car's "weight" for purposes of calculating the grip of the tires on the road, but doesnt increase the mass of the car that they have to change the direction of.

    This is why the "ideal" race car is a stick figure formula 1 type car with a giant engine and huge wings. The downforce keeps the car stuck on the road with the force of many times its weight, but since the car is so light it can change direction with mind boggling speed. This is why formula one cars can develop over 5gs of sideways acceleration. The powerful engine helps to generate speed which in turn increases downforce. The cars actually grip more the faster they go.

    250 mph top speed is retarded because the only places you can really reach such a speed are on a banked oval track. Overlooking the fact that the veyron is a heavy barge of a car and has mediocre street tires... Even the fastest of close wheeled race cars (many of which have comparable horsepower, much stickier tires, far less weight and better aerodynamics) are hard pressed to break 200mph even on tracks with enormous straight sections. Mostly they keep to speeds below 150 because of having to constantly brake for curves. It would be a much lower speed if they had street tires instead of racing tires. 250mph is a useless speed until tire compounds and braking systems have advanced a VERY long way. The trick is less in getting to 250mph than it is in avoiding things going slower.

    As for aerodynamics, it isnt very hard to keep the car planted, even without fancy computer desgined undercar tunnels. There are tons of books on desgning and testing over and underbody aerodymics- much of this knowledge has been floating around for decades.

    As for 1000+ hp, there are a ton of big block v8s making that power all over this country. Some making significantly more. A few even do it on pump gas.

    The pop on the rally car is NOT from the car running rich, it is from the anti-lag retarding timing when they release the throttle. The ECU chooses to reduce power by retarding timing rather than by closing the throttle- this keeps the turbo spooled up. The popping and banging is because the fuel air mixture isnt entirely burned in the combustion chamber and instead inside the exhaust/behind the car.

There just isnt that much pwoer to be gained once the intake and exhaust are letting through enough air to keep the cams happy. You are basically just removing very slight pumping losses vs actually uncorking the engine's airflow.

    Turbo cars benefit greatly from running no exhaust because the whole efficiency of the system goes up the less restriction you have after the turbo. Fortunatley the turbo itself acts as a very effective muffler, so noise pollution is actually quite low in this situation. Boost builds more quickly and falls off far more slowly.
