- ctheory, on 10/12/2007, -0/+15They really are fun and amazing. What a lot of people don't understand about the racing slicks, though, is that they're made of a very soft sticky compound (duh), but more importantly, a very soft sidewall. That's why you see the tire "wrap" or "wad" up.
For those that are interested, you have a number of things that happen with those tires. Normally they're run at very low pressures (8 lbs of air to almost 18 lbs.) to absorb the shock of the initial launch of the car. You run into two problems though... sometimes the tires can grip too well (not enough air pressure) and cause the car to bog. By bogging, for example... you launch the car at 5200 rpm, and when you release the clutch, the tires absorb so much of the inital shock that it causes the car to drop RPMs drastically, moving the car out of its ideal powerband and not moving efficiently. The tire can also "wrap" or "wad" enough that it causes "tire shake". We actually had to install extra padding/bracing for the driver, and extra bars to the rollcage to help alleviate some of the problems we had with tire shake. With a camera in the car, it dismounted and broke both the camera and the laptop left in the car for tuning/datalogging purposes. Also had a full mouthguard (top and bottom) because of people shaking so much in the car that they bit portions of their lips/tongues off, although that rarely happens today, people have gotten smarter. One guy that we raced with, Steve Grebeck, drove a mustang called "psycho bitch", you can google it... the car shook the tires so hard that it actually caused him to pass out about a quarter of the way down the track. Tire shake can be very, very nasty.
The other thing that can happen is that the car can have overinflated slicks and cause tirespin (spinning the tires = not going anywhere = bad) and also cause the car to bounce on launch.
That camera is freakin cool, you can see a bit of tire shake in different points in that video. Good stuff. :D - beatphats, on 10/12/2007, -1/+15Wow, those drag racers have sooo much torque, they actually compress and twist the tires, that's crazy.
- BMW7Series, on 10/12/2007, -0/+7To me it was amazing watching the pistons firing one by one.
- salensa, on 10/12/2007, -0/+6machines are unbelievable, however really interesting
- Heckler078, on 10/12/2007, -1/+5thats some mad power right there :O
- blackmariah, on 10/12/2007, -1/+5No you don't. As counterintuitive as it seems, there is such a thing as too much traction.

You're probably seeing the 60 Hz AC flicker. - enivid, on 10/12/2007, -1/+4It's amazing how camera flashes still seem quite fast!
- DrGonzo1184, on 10/12/2007, -0/+3@blackmariah
please explain how you can have too much traction on a car. I am honestly curious. - wvannus, on 10/12/2007, -0/+2Gonzo:
Rolling resistance.

Sonic: More like 1/20. Most Top Fuelers have 6k bhp. - VeganG, on 10/12/2007, -2/+4No one else is nearly as incredulous over technicalities as yourself.
Are you looking for an excuse to prove that you went to a pretentious film school or something? - LecherousVenom, on 10/12/2007, -0/+2It's just like YouTube...but with twenty six thousand more ads.
I like ads. - GuyHitByTruck, on 10/12/2007, -0/+2I didn't notice any flashes, but I did notice the green light at the end. Is it just me or did it seem to flicker?
- delinka, on 10/12/2007, -0/+1Yes, that green light is flickering. I assume it's an LED-based light which, depending on it's power supply, actually does flicker faster than your eye could see.
Incandescent bulbs *would* flicker based on your home's 60Hz AC (in the US), but they take so long to cool down that there isn't any flicker for a high speed camera to capture. - Jozer99, on 10/12/2007, -0/+1Yeah, then you could change them every mile or so, and rebuild your engine after every 1/4 mile!

- trev0006, on 01/24/2008, -0/+1That is some amazing tire footage, the stress on the tires is amazing. http://www.discountpartcenter.com/
- proggieus, on 10/12/2007, -0/+0the 6000 to 7000 Hp figure is based off a strain gauge on the drive shaft, there is no dyno that can measure this much horsepower so the reading was only what they could get to the ground. it could be much higher, Ohh and the blowers take roughly 1000 housepower to run.
- Aggiemaster, on 10/12/2007, -2/+2sure the engines produce crazy torque, but those are some crazy tires sticking to the asphalt too. i want some of those suckers on my car.
- Abel1337, on 12/04/2008, -0/+0Thanks for the post. I digg it! If you guys like watching posts specifically about tries that cause wrecks check out: http://www.needanewtire.com
- cmyke, on 10/12/2007, -0/+0Did you ever do anything with rocket cars back in the day? I hear they were outlawed because drivers were literally passing out due to the g-forces!
Not to mention they'd do the quarter mile faster than the nitro dragsters of today.
I also remember hearing about them running out of fuel halfway down the track and coasting the rest of the way - ig33k010011, on 10/12/2007, -5/+4duplicate story....
- Sonic_Molson, on 10/12/2007, -5/+3Sounds like a huge waste of fuel. Your car doesn't have 1/10th of the power those drag cars do.
- oddfreakperson, on 10/12/2007, -2/+0http://duggmirror.com
- rhettnyedotorg, on 10/12/2007, -5/+3dupe, too.
- unloud, on 10/12/2007, -7/+2I taught I taw a puddy cat.
- Foxphoto, on 10/12/2007, -7/+2not the 1st time on digg
- oneshare325, on 10/12/2007, -9/+3That was pretty cool, but this is like the 4th time I have seen this video on the front page!
- evil-doer, on 10/12/2007, -9/+2slow motion camera? and no one here has questioned this? this is called a *HIGH SPEED CAMERA* people. the result is slowed down because the frames are played at a slower rate. jesus christ.
