ok this video is one of a kind, it shows how close a indy car race can finish. It shows the closest finish in history.

OH MY GOD !!!! that was really close !!! awesome .....

Yeah i know i was there

omg, that is really close, i was so excited and scared when it was the end of the video because i was scared they wotn show how much difference there was, and that picture, wow, if the Penzoil yellow one was abit more closer, that would be even more awsome...

that would have been too close to call

wow, funny that, i was thinking about that the other day; how close have cars finished next to each other... thats crazy :D. thats so dangerous as well... imagine if the cars wheels got a bit tangled up, slowed down a lot and all the other cars behind them piled up and up in a massive crash... ouch

Why did you have to make a thread about a video you already posted in another thread?

I am wondering the exact same thing. Plus the his comment in that other thread was rather dumb too.

i don't know whty i did that it was just spur of the moment

LOL! I love how the commentators were going totally crazy! Bahaha
Damn, that was a hell of a close finish though. I'd die from excitement if I was driving one of those cars.

well they do travel at 200Mph +

Thats very close! Nice video.

well they do travel at 200Mph +Yeah... man, I don't see why they design the car like that, by the way. They're supposed to go +200 mph on an oval, but they appear to be designed with downforce in mind rather than minimum drag.

Yeah - 200 mph without downforce is like 10 million steaks and no fork.

EDIT: Go on MSN Tom!

Meh... I don't know. In sportscar racing they always use low-downforce set-ups on ovals, and high speeds tracks in general, so these cars must be absolutely crazy at normal tracks.

Yeah, but not as crazy as an Ariel Atom! :D!

BTW is your MSN working yet tom.

True that thing is off the hook

Yeah - the Indy car racers have bodywork - the Atom doesn't :D

if you crash in the atom you are secrewd

Yeah, but not as crazy as an Ariel Atom! :D!

BTW is your MSN working yet tom.No, but I haven't tried rebooting my machine yet because I was busy saving 470 pictures of Alessandra, so I'll try that now. Keep your fingers, toes, eyes and other appendages crossed that the reboot won't cause my fan to start playing longhaired, 'cause in that case it will take an half hour before I can use my computer again.

The bodywork on the racers is needed for aerodynamic purposes. The Ariel is just a toy. It's draggy as hell, but it doesn't matter on a car like that.

Lol - its hot though

GOOD LUCK!

Wow that was crazy, Nerves of steel, I would be too scared that I would hit the guy.

Yeah - 200 mph without downforce is like 10 million steaks and no fork.

EDIT: Go on MSN Tom!

what an amazing way to explain it :D

downforce = grip, and without that grip, the cars would be flying all over the place... at speeds in excess of 220mph, without downforce, they could be makeshift aeroplanes on the slightest bump they hit..

It does equal grip, but it's called aerodynamic grip, which is the downforce you get from all the wings and sidepods and bargeboards.

The other type of grip is mechanical grip, which is the grip you acquire from tyres, damping settings and suspension settings.

Yeah they are both very effective and are essential for the indy cars so they can be streamlined and achive 220Mph +

The other type of grip is mechanical grip, which is the grip you acquire from tyres, damping settings and suspension settings.

Mechanical grip is only predominate at low speeds, such as F1 cars going around Monaco. Yes they run huge wing levels there, but that only enhances the overall grip characteristics of the car. Mechanical grip is also a lot more situated for tight cornering, such as coming out of tight corners so that you can go on the throttle earlier and more consistently.

Indy cars need wings because mechanical grip can only help the cars so much. I was going to ask why Indy cars use ground effects more, but as F1 has taught us all, ground effects + skirts + slight rise in car = car flung into air or really fast into wall. Wings make the car stable at such speeds, and allow the car to take the banked corners faster than what they would without them.

But i'm sure you knew most if not all of that anyway...:p

EDIT: Oh yeah and any open-wheeled race car is never streamlined in general. They may have streamlined characteristics, but I would never describe an open wheeled car as having a general streamlined shape. The main reason being that they are open wheeled, and forward rotating wheels are heinous crimes to the aero efficiency of the car.

EDIT 2: This is to Lp640, the aerodynamic grip of any car does not contribute to its max speed. If speaking about wings, it actually decreases the cars ability to both reach certain speeds, and the time it takes to get to those speeds solely because of the fact that wings cause drag. The offset of which is that wings = downforce. Mechanical grip contributes in a sense that good mechanical grip would provide better grip (and thus reduced wheelspin etc etc.), but doesn't help the car reach great speeds. Grip can only be used in cases of cornering and acceleration IMO.

jesus. thats amazing. 99 ten thousands of a second, thats like, uh

.00099? i think, i dunno. too fast for me to count fo sho, lol

jesus. thats amazing. 99 ten thousands of a second, thats like, uh

.00099? i think, i dunno. too fast for me to count fo sho, lol

i think its 0.0000099 of a second.

thats crazy :|... it shows just how close the cars were and just how fast they were going...

I saw this on the SPEED channel awards thingamajig, and I was completely shocked when that guy overtook the leader! It seemed like it was only an inch away from crashing!.....

i think its 0.0000099 of a second.


Actually, I think it's 0.0099. 1 ten thousandth of a second would be 0.0001, so 99 is 0.0099, which is actually close to a hundredth of a second. It's just more accurate to describe it as 99 one thousandths, or 99/10,000, rather than a hundredth, which is 1/100.

yeah but that is so gap was so small he must have only beat him by about a length of a finger nail

Just to throw some facts into the pot, Lets use Fontana as a example. In the first turn ,the right front spring sees about 7,000lbs of force. They will use a 2,100 lb spring. The right rear is the killer it sees about 8 to 10,000 lbs of force in spikes of course, they use about 2,400 to 2,600 lb springs there. Bearings see a ton of load and needless to say parts get cycled quite often.

wow....very interesting. That must be FIXED!!! jkjk. what an amazing result too! all those cars fighting for positions..

wow....very interesting. That must be FIXED!!! jkjk. what an amazing result too! all those cars fighting for positions..
yeah there can be 4 cars fighting for the came peicce of road at a time it's breathtaking stuff

wow....very interesting. That must be FIXED!!! jkjk. what an amazing result too! all those cars fighting for positions..

i dont think it would be possible to fix that :cool:

CART cars run turbo motors and a spec ECM. Each driver has X amount (over 1 min at some tracks) of "power to pass"; increased boost. Some drivers waste it early; some save it for the finish.

^ yeah in spose but if you waste it at the start it won't be there when you need it the most
