Depends on what kind of track you intend to use it on; straight, incline, etc. I doubt that aerodynamics will make a whole lot of difference, but you can try something aerodynamic. I've seen a number of pinewood derbies and I can't say the wedge always has the advantage. If it really made a difference nearly all would tend to win, but they don't. I tend to believe that other factors are more significant. Things like weight and friction. Make the wheels as 'slippery' as possible about the axles. Maybe you can use Teflon bushings for axle sleeves, or Teflon axles  as well as Teflon bushings unless there are restrictions of such things.\n\nAt one time I started to crunch some math to find the optimum design, but I was always derailed on some other endeavor and never finished. It's not a trivial problem actually if I remember correctly. Anyway, I'd say that the weight should be evenly distributed. So balance any added weight with the weight distribution of your body style so the mass is effectively centered width-wise and length-wise.\n\nA light car will leave the gate faster, but the heavier car will not be as affected by undulations and so on on the track, and it will tend to want to continue longer than the light car. How much heavier?........sorry.....dunno. That was part of what I wanted to find out.\n\nIf the cars start on an incline then I'd say the weight distribution should be slightly forward. If the cars are propelled on a level track, depending on the nature of the launching mechanism on the car the weight should be centered as I mentioned above. If the cars are propelled on a straight track from behind, then you'd also want a bit of excess weight slightly forward. If the car is propelled by a sling mounted on the front of the car, then the weight should be situated slightly toward the rear.\n\nThe wheels should have NO slop in them, but completely FREE to turn. The mounting of the axles should also be done just so as well. I'd say this is more in line with how you distribute the weight of the car as a whole. You don't want weight 'hanging' over beyond the outer perimeter of the wheel-base. And don't have it shifted more to one side than another. I doubt you'd do that, but I've seen some pretty crazy designs.\n\nSince you mention motors, I guess you'll be launching from a level surface. Make cavities in the car to lower the motor into to keep it from being too bulky. Selecting the motor is up to you. Find one that has a good power:weight ratio. Meaning.....high power against low weight (that's obvious ---- right?). Power it with good batteries. Don't get the cheap crap from Giant Eagle. Go to a hobby store and get good ones. Measure their voltage and make sure they are at or above their rating, and if you use more than one that they are as closely matched as you can get. Mount the motor as closely to the driven axle as possible. Avoid linkages. This will add weight...unless you have to. maybe consider driving all 4 wheels at once? BUT...they will have to be synced VERY well to pull this off, otherwise the car will fight itself and slow you down. If you need to do any wiring....use very fine gauge wire. Enough to handle the amps needed, but just barely! The finer the wire the less weight you have to haul. Ideally try and engineer the motor so you don't even need wires.\n\nIf you have to connect the motor to the axle with some kind of gearing....I'll come over and bi+ch-slap you for even thinking it......don't do that! Try and use a motor/axle assembly. Otherwise you run a terribly high risk of driving the axle out-of-center and wasting power by unnecessarily torqueing the axle. Meaning as well as turning the axle it will tend to want to rotate....no no no no no....got it?\n\nMake sure any motor you use doesn't have a wild magnetic field. Check it by seeing how many paper clips you can 'stick' to it, and how far away this

Yeah...  What Marky said.\nThen add a performance chip, fuel injectors (if necessary), larger throttle body, and mass air flow sensor (if applicable). Intake manifold....\nThen put a huge Turbonectics Turbocharger on it!\nTo go faster, you need to get more air and fuel in, and more exhaust out.\nHave fun!!

From experiece I can tell you I don't like front wheel drive in small cars with short wheel bases. When the brakes are applied, especially on slippery surfaces, they have a tendecy to go into a revolving skid because they are so front heavy, In other words, they have a tendency to revolve around the heavier front end. A rear wheel drive car is better balanced . A front wheel drive car has very good traction though becase of so much weight over the drive wheels.

There are two types of Traction Control. One system applies the brakes to a specific wheel when a sensor detects it slipping. The 2nd way is for the car to slow itself down by reducing the amount of fuel when it detects wheel slippage. Many cars with Traction Control use a both systems.

a racer car !!! hihihi :)

four-legged are usually faster than two-legged, so it's F1! ;) both are equally interesting to watch though.

I don't remember very well I but I red somwhere about a F1 car beating a F16 fighter on a 2km distance.\n\nLet's take an example: \nRoughly a 747 weight about 400tons and has 4 engines of 25tones of thrust. This would lead to a maximum acceleration of 0.25Gs at take off. I'm sure a fast car can do better than that

Top speed on a NASCAR car is just a touch higher, 205 versus 190.  But, because of light weight and aerodynamic downforce pressing down the car to the track, the F1 car can corner, accelerate, and stop much, much faster.  Cornering iis more than twice as fast.  If a NASCAR car can do a corner at 75, the F1 car can do it at more than 150. Braking is also extraordinary.  An F1 driver once said that letting off the gas is like hitting the brakes in a normal car, and that hitting the brakes is like having an accident.\n\nThey're so different that it's difficult to say which is harder.  F1 cars race mostly against the track, NASCAR cars race mostly against other drivers.  It's very difficult for a top driver in one to go over to the other and be a top driver there, also.

Ok assuming you are part of the real world and race on the street where they dont have a tree, sorry race chick. There are several things you can do to improve launch i have had a 89 mustang gt and i didnt do alot to the engine at first it was all about suspension and other things to get me off the line faster the first thing i done was put in a trunk mount battery kit to help waight transfer then 40/60 drag shocks fron edlebrock and eiback 1" lowering springs in the rear also i ran a pair of Nitto drag Radials and 3.73:1 rear gears you can email me @ williamb606@yahoo for specifics

hey no worries ! u need not need ne xperience ! go karting consists of ony steering, acceleration n braking ! no gear control !

Traction control is fitted to my car, it is a system where each individual wheel will stop and start in rapid sucession when slipping or sliding so that you can grip the road better, thats the basics anyway

no, the whole point of "drifting" is to set up your suspension for oversteer, and then controling the drift with the throttle not the steering wheel. when you think about your already asking the front whhels on FWD car to; stop, go, and handle cornering. with more power to the front wheels, when you accelerate out of a corner a FWD car will just understeer A LOT.

I have raced cars legally and illegally in the past and the best way to downshift and get full acceleration is as follows:for example if you are changing from 4th to 3rd(or any other gears) to accelerate or overtake a slower vehicle you should press the clutch,change to neutral,blip the throttle(jab the throttle peddle momentarily just to raise your revs to match your engine speed to the wheels or you will lock up your wheels or get a jolt),then put it into the desired gear you want and release the clutch.You have to do it lightning quick for it to work properly.\nAnother useful tip to be an even faster driver is learning to use the brakes and change gear at exactly the same time when on a twisty winding country road (when going into corners which you have to change down for)this is called heal and toe.First you have to learn left foot braking and get used to the force you apply to the brake peddle with your left foot.At first you might press to much(everyone does this at first because you don't realise how sensitive it is)oh yeh make there are no cars behind you.once you have got used to that start doing it all the time when racing on a road anywhere (as long as it's safe).The trick is when coming to a bend that you have to brake and change down gear for is to use your left foot to do the braking and change gears normally with your right foot so you can leave your braking till later and closer to the bend,because your right foot is already changing down the gears and your braking whilst you are changing gear instead of having to do the same things with your right foot wich takes longer and more distance.\nWhen you come to a fast bend that you don't need to change down for but need to lift off the accerator don't do it.Just gently dab the brakes instead of lifting therefore your car is still accelerating and keeps it momentum through the bend which is alot faster(thats what micheal schumacher does in his f1 car) but your brakes will take a battering if you keep doing it.\nThey are the basics of how to drive a car very fast I have beat faster cars than mine using these things as well as others.If you want any more info on how to drive a car really fast e-mail me igenockey@yahoo.com.Hope I helped and just be bloody careful because it is easy to mess up.

You can start out with two equations:\n\nF = k*M*g   :  Where F (Newtons) is the static friction force of the car, k (unitless) is the coefficient of static friction which we will solve for, g (m/s2) is acceleration due to earth's gravity, and M (kg) is the mass of the car.\n\nFc = M*V^2/R  :  Where Fc (Newtons) is the centripetal force due to circular motion, M (kg) is the mass of the car, V (m/s) is the velocity of the car during the turn, and R (m) is the turn radius.\n\nThe car must maintain its grip on the road to meet the conditions of the problem, so we have to set F = Fc and solve for k, which will give the minimum value to maintain traction.\n\nSo, setting them equal and solving for k gives:\n\nk = V^2/(r*g) = 0.83513...\n\nYou should notice that the car's mass cancels out so we never needed it.  To get the answer, remember to convert 95 kph to meters/second and use 9.81 m/s2 for g.\n\nA value larger than k means that the tires have extra grip and could handle a tighter turn.  Any less than k, and the car's centripetal force would overpower the force of friction of the tires, and the car would slide.\n\nI hope this helped.

Making something go fast is not all that difficult much of the time, it is about making it *controllable*. Speed (power) is nothing without control.\n\nIn the air, not only do you have the option of full 360 degree movement options (esp with rotating wing aircraft), you do not have "blind corners", slippery road surfaces and sodding speed cameras.\n\nIn many ways we DO embrace much of the other technology though, from lighter materials, more aerodynamic design and advanced navigational facilties (FRED / GPS) etc\n\nOne thing that has never seemed to make it to the road is an engine with twin spark plugs - a requirement on all conventional engined aircraft. Not only does it give backup (less critical on the road) but ALSO makes a fair difference in economy. When switching magnetos (ignition) from BOTH to Left or Right, a drop of 50-100 RPM is not uncommon - suggesting strongly that the additional spark does indeed improve effieicney and power output.\n\nAeroplane engines are also happy to be leaned out considerably more than automobile engines. Again allowing for greater economy AND power.\n\nAre there any other technologies you are thinking of specifically that you think should be incorporated into cars?

Remember you need to have a 28" waist, otherwise you will not fit into the cockpit. Hopefully you are also still young, for you need about 300 hours of TEST driving in a F1 car, not mentioning the other formula driving categories that you need to race in too\n\n-- Otherwise , best of luck
