I realize this isn't the lounge, but figured the readers of this forum would be most interested.

Now that is some braking power. Keep in mind the Porsche's engine sits BEHIND THE REAR WHEELS! To stand a 996 Carrera on its nose like that...well...I'm speechless

 

what you can't see is the jack at the rear of the car...

 

brake envy?

 

you know it. I still can't get over it.

 

could that be with the help of some aerodynamics just for show. because it is a brake sponsered 996.
Ohhhhhh!!!! Look back there on the track, there is a transition from concrete to pavement. That could have been the cause of the "bump"

 

clearly I think it would be better to be breaking with 4 wheels - whether the front springs are too soft allowing a bad shift of weight/etc. is unknown.

 

man that's sick!

 

WOW!

 

hehe never thought I'd see stoppies on a car

 

Its from a dang bump in the road while braking hard. Theres no way it could do that alone.

 

It's from a bump or the photo is doctored. No way in hell a car could do that, the front tires would lock and skid before allowing the rear end to rise like that. Absolutely impossible for the tires to provide enough grip to allow a decel that substantial.

If the car had its cg about 15 feet in the air, then maybe it would be possible

 

Could the car be going fairly slow, so that the friction of the tires/brakes is greater than the momentum/inertia (I dont know the proper term for MASS+SPEED) of the vehicle?

After doing some investigating, I am inclined to think an off camera elevation change as well

 

The picture is fine, it hasnt been manipulated at all and the camera is flat. I know it hasnt been doctored because the front tire is under a lot of load (it looks flat). The only reason it could be doing this is from that transition from concrete to asphault in the rear of the picture! and I will only say that one more time!!!!!

One thing we haven't considered is that the car may have been airborne, and what you're seeing is the 911 touching back down?

 

Thats what I meant, the car went through an elevation change right before the pic was taken (and it is now off camera to the right). The change from Asphalt to concrete looks more like a run off area on the side of the track.

but my question remains, maybe not for this car, but if you were going slow enough, and had brake bias all the way to the front - if the stopping power of the brakes is greater than the mass+speed of the vehicle , wouldnt it still have a chance of inducing something like this?

 

The rear weight bias of the 911 makes this pic impossible....

 

It's a trick car. The body and interior are mounted backwards. What you're seeing is actually the launch

 

i think if this was a civic, and it had a big bi-plane style wing on it, the wing was angled up so at speed it would creat lift... it could drive down the hiway with the back wheels off the ground.

seriously tho, i agree that the brakes are not bringing those wheels off the ground. i've done some freestyle car jumping in my day (not in a porsche, mind you) and i could have taken simlar pictures. boy it'd be fun if brakes/tires could bring the back end off the ground. that'd be a hoot at red lights.

 

No, no, no. Brakes do not stop cars, tires do. The tires could never provide enough grip to make that happen.

 

 

Yup,what he said.

 

OK just to stir the pot, dont drag slicks make enough grip to lift the front end of the car off the ground? Why wouldn't this work in reverse if the tire are was large enough?

 

Drag cars lift their front tires because the natural result of instantly applying several tons of torque to the drivetrain of a car on slicks is for the pinion gear to momentarily try to climb up the ring gear instead of turning it. The combination of sticky rubber and low air pressure (along with very flexible sidewalls) won't allow the tires to break loose, so if the ring gear can't turn, then the pinion gear must go up... and so does the rest of the car it's attached to. Assuming enough torque, and assuming nothing breaks, of course.

Drag cars can generate far more than 1g of acceleration from the power they apply to the drivetrain, given enough traction, from a standing start. No car generates much more than 1g of braking power with the brakes alone. The tires will lock and slide long before you could generate enough force to lift the rear of the car. Even on slicks... check out a NASCAR track some time.

My money says that someone snapped a picture immediately at the point of touch down after the car was (deliberately or otherwise) jumped.

 

IT could have hydraulics. LOL!!!!!!! Let's see some 3 wheel motion. hehe. There's some definate inconsistencies here. But an obvious physical explanation due to the load on the front tires and the amount that it's suspension is compressed. I'm thinking a leap in the air or something as well. A little camera trickery. Quite interesting.

I think it's funny that is has a big *** sticker on the front valence saying, "Brake Parts". What a great advertisement. hehe.
