82 trans am and a 90 degree turn at 75mph

[teckmaster]

I friend of mine says he can take his 1982 Trans-Am at 75mph around a 90 degree turn and stay in his own lane. no mods to the car. What do you think?

 

[Chooie]

if there's like 60 degrees of banking, i'd say... maybe. You also have to know what the radius of the turn is. Does he mean likea turn around a city block, or a sweeping 90 degree turn on a highway.

 

[yakko]

Must be a really wide lane. If not don't be in the other lane.

 

[Wangel]

A friend of mine?

I've heard: A friend of mine has a faster car, a friend of mine is going to kick your $ss, a friend of mine can play baseball better than you. Are these friends imaginary or real? My guess is imaginary!

I think that guy must have got his hands on some old tapes of a 1-season show called "automan."
And his hands on some funky sh!t too.

A friend of mine sells bridges to eskimo's

 

[Santa]

Hey so its your friends, Eeks, that has been tricking my fellow eskimo friends..
no soup for you and your friend this christmas

<< A friend of mine sells bridges to eskimo's >>



Isn't it:

A friend of mine sells ice to eskimo's

Lets just hope that when he tries this he is taking a left turn so that only the barrier is smashed and not somebody else.

 

[Ronstang]

For this feat to be accomplished I think the type of car is unimportant, what matters is the tires. I don't know of any available street tires that would let any commonly available automobile complete a turn like this.

 

[Chooie]

Lozers car could do it.

 

[Digobick]

I didn't know Hot Wheels made an '82 Trans-Am!?!?

 

[PG]

I don't see how this is possible unless his car has an amazing resemblence to those cars in Tron.

But does he mean corner or turn?

[ratkil]

technically to make a 90degree turn the wheels on one side would have to reverse like a bulldozer or tank. Luckily my dad works for Catapillar, lucky me, so I have a D-8 that can make a 90 degree turn at 75 mph

 

[BiB]

LMAO ratkill

 

[Warrenton]

Actually its very possible, nothing says it isn't a left turn with buildings all around that he bounces off of.

 

[oldandquitemad]

I owned (and my son still drives) a 88 (or was it 89?...damn this gettin' old stuff) Camaro RS. It's a pretty flat footed automobile.
However, I really do NOT think it could do the turn at that speed AND maintain traction. Can he control a skid through that turn? With practice, probably. Will he eventually screw up? Probably.

 

[Sephiroth_IX]

Observe the sig.

 

[Tominator]

If the lane in question had stout guardrails....of course it's possible!

 

[Pacfanweb]

It's possible if the turn is a sweeping turn that takes up about 1 mile
No way if he means he can just abruptly turn at that speed. 1980-81 (2nd generation body style) and 82-84 (third gen.) Trans Am's and Camaros were total performance turds. The worst T/A's and Z28's ever made. Actually, the Z28 2nd gen. was bad from 74 to 81. The T/A actually was still pretty fast all through the 70's, until 1980 when Pontiac stopped using their own 400&quot; engine and used a turbo 301.(total dog) From the mid-70's until 79 the T/A was the fastest car built in America, except in 1979 when Chevy built the last 1/2 ton trucks with 454 engines...those were really fast.

 

[Mister T]

Here is the answer: NO.

Here is the Physics to prove it:

Centripital Acceleration = (Tangential Velocity)^2 / Radius

The Tangential Velocity equals 75MPH or 33.528 m/s
The Centripital accerlation is also known as the Lateral G's when you test a car's cornering ability.
One of the best cars in handling is the 911 Turbo which has a lateral G of about 1.00.
The 911 turbo definitely beats the transam which probably has a lateral G of about .9
Lets assume for reason of arguement that the transam can do 1.0

So, what kind of turning radius would be need for a car that can do 1g Lateral acceleration at 75 MPH??

R= V^2/A = 33.528^2/1 = 1124.12 meters or .698 miles.

This is obviously quite a ridiculous claim. This also assume ZERO banking.
So, there is no way a this car can make a 90 turn. It can't even stay in a circle with a radius of 1/2 mile.

Later.

Hmm... Maybe if the car was an 82 RABBIT! :Q Just kidding.

And even in that car which when driven is often claimed to be like &quot;driving on rails&quot; can only do just under 60 in a corner and it WON'T be at 90 degrees but more like an extreme outside to outside curve (if you don't like my driving, stay off the sidewalks) WITH the back wheels breaking loose half way into the turn.

I know... I do it on the backroads on the way home from work. :Q

No way a Trans Am is going to do that. Too big, too heavy and the rear wheel drive may actually be a DISADVANTAGE for such an attempt.

My dad used to be an SCCA racer. He got a sponsorship by a GM dealer in town and they switched him from his typical rice burner or bangers and mash burner into an 1982 Camaro Z28 (then new) and a different class (of course).

He lost time in every race. Reason? He had to slow down for every corner because the car had to much pitch and roll so it felt very uneasy in most corners under 40 MPH and it's own mass would throw the car sideways over 40 MPH.

Thank goodness that adventure didn't last more than one season.

Now, If he did an e-brake slide at 60, that would pull the car to 90 degrees. Hell, that could spin the car completely around, but that's not what he's implying, is it?

I'm going with the Automan theory. I can just picture teckmaster being played by Little Ricky and getting thrown against the glass.

 

[RSI]

:Q

What he said.

 

[Ruark]

Sorry Mister T, but 1g is not &quot;1&quot;, but rather 32.2ft/s^2 in english units, and 9.81m/s^2 in SI.

So, for a=v^2/r:

a=32.2 ft/s^2

v=110 ft/s

Solving for r results in a radius of 376 ft.

A more realistic lateral g for a car of this vintage w/ Pep Boy tires is probably more like 0.80g or 25.76 ft/s^2, which results in a curve radius of 470 ft.
