Ok boys, here is some simple arithmetic for ya.

Take a one wheel diff, 3.00 x 1

Jack up one tire off the ground (trans in neutral)

Mark the tire and mark the drive shaft

Now turn the tire one full revelution and observe the driveshaft

It will turn 1 1/2 turns that = 3.1 ratio

Now turn the driveshaft one full rev ...it will turn the tire 2 full revs

Get it now??????

 

only the Guys who have never had more then 300HP would say somthing like that..LOL

flexing the HP in your Hot rod it whats it all about baby!!
what you posted is the same thing has saying. any more HP then what you need is silly.. AKA..driving a Pinto

 

I had a 74 Mustang II Gia loaded with automatic transmission that could spin and flex all of it's 89 HP. Your point is what? Just because you can spin your tires does not mean you have a fast car or much less the ***** to drive it.

I've had cars with more than 300 HP and still think it's a waste of time and money. You can have all the power in the world it doesn't prove anything setting still.

 

my tire on my 85 came apart going about 90mph on I20. it just banged up the lower 1/4...i had a 76 pinto. i don't know how little the hp was but when i first got it my 0-60 was 20 seconds and i got it down to 13 with some tinkering. i want another one. i'd put in a 350 chevy of course.

 

people don't understand how complexity of an open diff hahahh ... one wheel spins nooo it's witchcraft hahah and now ur telling me if u hold on tire it will spin the other faster 0.0 this is magic ahahha.

man it's sad that people can understand this some was even able to build it with legos lol

 

xactly. my 4 banger s10 will do a burnout.

 

burnouts rule,i wouldnt do it in my car, but they look cool.i did see my brother take his 71 396 gmc to the track and he did a smokey burnout all the way-20 secs. nothing but applause.people like burnouts.just too bad that camaro dude had to pay the piper,ouch

 

In this case as well as in some others.......it has NOTHING to do with HP! That was all wheel chocks and buckets of water...........

 

take time to read the post.

we make engs with lots of HP.. so we can play..some of THAT play is doing a burn out,

this is like texing..you miss one tex and you could not keep up.. read all the post...

 

idk i think there's a difference between my V6 doing a burn out and some
big block nova blowing up the tires.

But it's just a show thing, just a better chances of breaking something.

 

stationary burnouts are lame. it would be interesting to me if there was no brakes, chocks, or water involved, and they rode it out to 60 or 70mph.

 

Take the time to clean out your ears, rub your eyes or put on your glasses.........your not catching what I am saying. I am not talking about you or how much HP YOUR car makes. MY POINT is that in the video they block the front wheels and spray gallons of water on the ground. You dont need 300+ Hp to do a burn out that way! I can do a one wheel peel that way in my 75 Dodge 3/4 ton! BIG DEAL!! Its like seeing long black marks going up hill......does that impress anyone?? Not me! I know the poor fool (in the black marks on a hill case) simply drove to the top of the hill and let the car drift backwards till he got near the bottom then stomped the go pedal. The momentum of the car rolling down the hill backwards breaks the tires loose allowing for some hellatious marks......big deal anyone can do it. My point being in any burn out contest that you have something holding the car back what have you really done? If your car has 300+ hp you dont need wheel chocks and water. Not the car in the video does sound good and probably had enough Hp to do a good burn out with out all the added BS. Get it? Got it? Good! Thanks for your time

 

I had a former co-worker who went to an engineering school in Longview, Texas, some of you may have heard of. He told me they would find a cheap junker every month or so, take it out to the woods where there was an old building slab, tie the car to a tree, and see how quickly they could get tires to explode. Beats studying. (gads, how time flies - that was 20 years ago)

I'd never enter a burn-out contest with one of my cars. I get my thrills in other ways. Burnouts are like government, a necessary evil.

 

LOL, you should read the post, i never posted you need HP to do a burn out.

i posted anybody that says doing a burn out is foolish.
has never had any HP.. but if you took time to READ the POST!
you would know that

clean your glasses, sparky
then read the POST.

take time to read all the post, from the first to the last,this is how a reply works., sorta like reading a book, front to back, (but you know that right?) not just skipping ***** nilly. then posting a reply to what you think some one is saying.
lmao.

 

stick to driving your 89 Hp cars, you dont need anything more,
us guys who like to spend more on gas then you do on a car, like to do things like a Burn out.. it's Fun to flex your Hp.

you will be alot more safe in your low power car, trust me.

 

You said it right there.

How does sitting still and spinning your tires prove you have a lot of horsepower? My point is I could spin the wheels of that Mustang and all of it's 89 HP. Now if you want a handful try driving it with a built 302 and a 175 HP shot of Nitrous. Not sitting still or being a parking lot racer. I mean racing it on curvy roads and when on a straight filling the front lift when you get around 140mph. That car held it's on againts my buddy's 72 Roadrunner.

 

Everyone who has ever owned a car with a little power (or lots of power) has done or tried to do a burnout. Most think it's fun to do. As long as people are having fun with their cars, there is nothing wrong with it.

The guy in the video was unlucky but he had fun before it happened and will continue to have fun telling this story over and over again.

 

i had fun doing burnouts when i was learning how to drive.... i also had fun crawling when i was a baby.

 

But, did you ever do a Burn out in your walker!

 

sooo...does everybody understand how an open diff works??? seems like alot of people dont.. 83 Crossfire TA knows what he's talking about

 

"Not so Much"

all you have to do is look at your speedo.. it tells it all.
speedo sits at 120mph and you sit in one spot.
tire smokes.. plane and simple. it dont = one tire doing 300MPH

and iv seen brand new cheap tires fail. before getting out of the shop.
it's fun to flex your HP, by drag racing/ burn outs/ drifting/or any other wheel sports. for anybody to say doing a burn out is foolish.. i say. stick with your beater streeters. and leav the wheel sports to guys who understand whats it's all about. and like to have fun.. sorta harsh, i know, but then so is calling anybody having fun with his car a fool.

think about it.

this is having fun with your car.
and having fun is what it's all about.

 

He can also add this to his story..."I used to have a decent looking car, until I entered that burnout contest"!!!!

At least I WOWED the crowd, before I had it towed home!!!

 

just like the Guys who stand there cars on the Bumper, then slam them down, or flip them over, it's all about Fun!!

 

speedo will read driveshaft speed.... which is the same regardless of what tire speed is.

 

the tire speed is the the same.. just like if your driving.

drive line speed, is the tire speed.

 

Is the drive line speed (speedometer reading) indicative of the stationary tire speed (relating to the car doing the one-wheel peel)?

Bill

 

What that guy did was NOT a burnout.

This video will explain in full detail what a BURNOUT really is. And I as an American will never do another like seen in this threads first post or in the following compilation

http://www.youtube.com/watch?v=rnCxSXoEcmE

 

Are we still arguing about this?

The "How Stuff Works" animation clearly shows that the "outside" wheel moves faster with the same driveshaft speed than it does when both wheels are moving together. Yes, in fact, when one wheel is not moving, the other wheel will move twice as fast with the same driveshaft speed with the typical spider gear type differential.

 

Sad even with animations people still don't get it and need more explanation. Well not sad, but disappointing. I mean what more is needed than that animation. Which colorfully shows the gears turning at different speeds per wheel.

 

It's like the old plane on the conveyor belt threads of people arguing back and forth if it'll take off or not.

 

the out side wheel is free wheeling..it's not driven..LMAO (with a posi)

you guys should know that. it's the inside wheel thats driven when turning.. with a posi or a open diff..lol

and a open diff,(NONE POSI)only drives 1 tire.and it swaps back and forth with turns,. and the speedo will give you the tire speed, (or nascar should get into this..LMAO)

this is why i dont Buy into alot of this stuff posted on sites..lmao!

(by the so called pros)

the free wheel moves with ground speed.
Ground moving under the tire faster on the out side,OF THE CAR
see the pretty colors moving?...LOL

WE NEED THAT animation with the Guy beating somthing dead, with a stick!

 

whoa, that's kind of a hard concept to get my brain around, lol! happen to have a .gif for that?

 

Of course it wont take off. Theres no air traveling across the wings to create lift. The whole Bernolli(?) theory only works with airflow going over them. Just like wheel speed on a stationary car NOT pushing its own weight, and NOT pushing through the air and dealing with drag, will inevitably have a higher speed than if it actually was driving down the road.

 

oh, with the engines off? of course it won't take off. i was thinking that with the engines on, it wouldn't matter since planes move by thrust and wheel speed has little to do with it. guess i didn't know the whole scenerio.

 

Oh crap, now I've started that here LOL Yes, it takes off just like normal and was proven. Think this is the original question.

 

artic, you really need to find yourself an open diff and start playing with it.

Many moon ago, I had a '79 Caprice that the PO (happened to be my dad) had the posi removed and an open diff installed (had an "incident" with cruise control and ice with the posi). The open diff had lower # gears, and when the car came over to me, I promptly got a speeding ticket (sorry for all the background, but it sets the stage).

I took the car to a local outfit that did speedo cals. The asked if posi or open, I said open. The jacked up one rear tire, slid their calibrated speed wheel to the tire, one guy held the accelerator so the speedometer showed 30 mph. The other guy, watching their speed wheel. First run it showed 50 mph. After adding a gear box to the speedometer cable drive, it read 60 mph. They gave me a before/after cert, I gave them a check.

(I got the ticket dropped by showing them the shop's cert. Now you know, the REST of the story. . .)

Some day, when it's raining or snowing outside and there's a warm fire in the fireplace, I'll tell you about the good ol' boy back home who had a home-made well drilling rig on the back of his old Ford pick-up that used a Model A differential to drive the raise/lower winch.
