There was talk in the Melb. Herald-Sun today of re-designing the cars. Apparently the Nascars are all the same under the "skins" and that�s what they are hinting at.

Arent Nascars built from the cage out (re Days of Thunder?). V8s start with a shell and build the cage into it.

As I posted early a Nascar style car would allow other manufacturers to get involved and make it a bit more interesting and allow Mitsubishi and Toyota to gain sales from racing success.

Are the front spliters and rear wing the same now as part of project blue print?
Going back to the VT VX model race cars the rear wing was different and Holdens had the gurney flap on theirs which was rumored to give them the good grip/drive out of the turns that the other make didn't have at the time.

todays v8super cars are built from a set of rails up using a set of panels to then be welded over the cage the ve has a couple of lenghts of rsj down either side then threst is hung over it as the racing ve is shorter overall than the road car by approx 100mm from memory most of it is taken out of the back door so as to comply with project blueprint. they are also a bit shorter between the front wheel and firewall the new orion body shell will be modified also. there is absolutely nuthing on a v8supercar today that has anything to do with a production car whatsoever apart from head and tail lights! they basically are like the control floorpan that vesa had at phillip island a couple of years ago with a falcon on one side and vz on the other..

Like I was saying...Tony confirmed...they are basically a NASCAR style mechano set already.

Might be wrong, but I think there was something slightly different about this crash - he seemed to be carrying more - how do I put it - 'transverse velocity' into the corner immediately before the crash, as he'd clipped the previous kerb and got out of shape. Brakes were locked up, and he slid sideways into the barrier at a higher 'sideways' speed than what most other accidents at that corner have looked like. Yep, it's a 200kph plus corner, but his sideways momentum looked to be larger than other crashes on this corner.

I wouldn't like the track layout to be changed, but I think a barrier system that absorbs energy without bouncing the car back onto the track should be implemented at T8.

Dangerous.... the term you are looking for is "yaw angle"
I don't really have an opinion on this crash, except to say that "motor racing is dangerous" at any level, at these elevated levels of risk the cosequences can sometimes be tragic. :cry:
Evertime this happens and my kids look to me for an explanation as to what happened to cause this crash, i get closer to hanging up the helmet.
tragic, just tragic for all involved.

I like the reference between the V8's being unsafe as far as race cars go, seeing they are based on Holden and Ford everyday cars. But then they said the purpose built Indy and F1 cars are safer and built to withstand similar impacts.

Ask Ayrton Senna the same question !!!!

Ask Ayrton Senna the same question !!!!

The autopsy of Senna showed he would have lived if he didnt get that puncture wound in his head from suspension piece.

The F1 cars did not get real serious about safety till Senna and Ratzenberger died at Imola on the same weekend with Rubens also having a big crash in qualifying with Wendlinger being seriously injured in the next race.

I have seen some results of crash testing the F1 cars and what impressed me is the 55g limit and how the graph shows it does not go over yet remains just under.
Courtney crashed a Jag F1 at Monza when suspension failed and peak g's were 53!

So basically when you design a car from scratch (F1) it is easier to implement things into design and far more difficult when converting a road car.
The V8 are not allowed to extend cage beyond pick up points in suspension to give a crumple zone.

Anyone see Kubicas crash in F1 last year and he almost went head on into concrete wall at high speed and lived,biggest recent impact in F1.

Modern design is all about controlling impact distance and time hence g forces.
90 Kph - 0 in 0.5 metre= 65 g's and fatal
100 Kph- 0 in 1 metre = 20 g's approx and very survivable if fit and healthy not good for pensioners with osteoporosis.

How far did David Hookes fall and die from head injury?

Motor racing is dangerous,always has been always will be.

And here is what happened to Ayrton Senna:-

 

 

Very Sad and F1 is no good for Bathurst.

Not much room  on that corner when they come so close to the wall to maximize the race line but a simple cheap solution would

be to use water barrels against the wall,the barrels can be set up like a damper with holes in them that allow the fluid to escape 

under force when hit,might mean moving the wall as well to keep same line or just place the barrels on existing track.

Yes it did happen pretty quickly UC,

 

and the reasoning behind this thread about - Concrete Barriers V Tyre Barriers



they said a suspension part speared Ayrton's head,

 

so Concrete is bad.

Fire a bullet into water and it splatters like hitting a concrete wall

Concrete verses rubber,both will have their good and bad points depending on where the barrier is set,water barrels or similar devices will

have the same attributes,problem with water is that it does not compress hence the need for holes in the devise to allow the water to escape 

on impact in order to soak up some of the impacting force and act like a 'shock absorber'... a bit like the damper on a car...only bigger.

Water is expensive now.

 

They use car tyres these days, which must be the cheaper option for concrete wall/bank/public area safety,

 

and see wide open spaces used, with the long straights cut down.

 

 

 

So the need for speed is changing to the best time a lap is done, although the Top speed is still quite high ( 360kph ).



seen tyres flying everywhere on the last race, which could hit something

I've begun reading all of Daves posts that i click to view as if they were a hip hop song. 

Imagine it to a basic 8 bar beat like this one:
