That Adelaide race was the second best race I ever saw...

Tremendous dicing for the places, Vern Schuppan holding down the cockpit bodywork as he diced among them, everybody really charging at the end of the series.

The Oran Park race was devastated by the raw new track surface, which John McCormack actually predicted before the race.



Interesting how Kennedy's Wolf does not have the pace of the front runners at Oran and this is explained away by the use of Aurora Spec' GoodYears.
Given that the same WR3 had been no slouch in Grands Prix, less than a year before, this highlights how much tyres made a difference even then.
Kennedy was being dropped by Lola T332s designed 3 or 4 years earlier, to a budget, and for production where the Wolf was very much a bespoke big-bugget design(for the time) and a regular GP winner in 1977.
The Lola T332, even in 1979, was still bloody fast in the right hands! :smoking:

The F1 cars won at Surfers Paradise, which was a circuit more suited to them...

More flowing corners, fewer straights pulling out of tight corners.

Of interest to Australian F5000 followers...

Our book will be on sale again at the Tasman Revival meeting next weekend, and for the first time the leather-bound limited edition signed by dozens of drivers etc will be available there as well.

I purchased the book last weekend at Sandown Historic race meeting. A fantastic read. Thanks for the great research and work involved.

A very impressive book and found out from reading the credits that one of the rad chargers in Appendix J now called Historic Touring cars used to be racing in F5000 days.
One Peter Roach. He was a real good steerer of a Mustang in our category. Always thought that he was a bit on the edge and now I know why!
He retired from our category after a huge crash at Calder in roughly the same place as Craig Lowdnes had his big crash.
Peter completely wrecked his Mustang and sadly for our category hasn't been a competitor since

Cheers
Peter Sneddon

Warwick Farm Tasman Meeting 1971

There were six McLaren M10Bs & one M10A.

There were obviously various views as to how the nose should be modified to get the best airflow through the radiators.
Or were they added to improve downforce or trim? The front wings differ as well.
Correct my terminology if it's duff.

The rear wings vary a lot too, dual plane, huge gurneys as well as the angles. I think that Niel Allen was trying to use the nose as an extra wing, given the fences on the side to what I feel was a necesary fence on the radiator outlet. Though all those fences must drag quite a lot and ideally would be better not there, though in our weather i doubt the outlet would let out enough hot air.

McRae was the first to fit parallel swing arms. It appears the later M10Bs were produced with that configuration. Compare photos of the two Allen M10Bs

You'd have to wonder how often he heard it rattle!!

Not unless an exhaust pipe broke...

AGP 1973, perhaps, in a later car? He broke one there in that.

Only parallel when looked at from the side. The pivot axis, top and bottom, were more or less parallel with the original installation.
Pivoting the upper link/trailing arm on an angle like that would have been to introduce some pitch limitation. Probably not a bad idea with all that torque and the heavy weight of the powertrain.

As in anti-squat, Pat?

I think that's the accepted way to dial that out.

I think you'll find those front radiator "fences" were for cooling purposes to prevent air spilling back down the radiator exit, rather than for aerodynamic down-force benefit

My understanding of the"Fences" is that they disturb the airflow causing a low pressure area behind the fence, this low pressure area then creates additional & a stronger airflow thus drawing more hot air out of the radiator area at a faster rate thus creating better cooling.

Great to see Gary's happy face again...

I've said it before, he was a wonderful bloke and put a lot into the sport during his short time as a competitor. He was quick enough to own a Warwick Farm lap record at one time and he greatly helped Larry Perkins on his trip to F1.

Thanks for those pics, Kym.

I thought that when I saw it...'That must be the first Exhaust Blown Wing'... but then realised they are blowing the wrong side of the wing =]

I wonder if there is a smoke stain under the wing at speed?

Plenty on top! I feel they may have had the idea, just blew the wrong side. Aero was a little more basic in those days!

I always felt that 'bottom' wing was of doubtful value - the air down there would be incredibly dirty. On the other hand, even a little extra downforce on that lever arm would help, providing the front wing/aero could balance it and remove the potential for high speed understeer.

Was it rules that meant the idea did not spread, or did Matich abandon the idea as something tried, but results not worth it?

Unless my age addled eyes mistake (and they often do), there's no mention this deep into the thread of...Tony AtoZ (Adamowicz). He did some business in this Formula with a great back-story on who and where his mount was prepared. Like I said...could be I'm wrong.

The McLaren M10A/B was a fabulous looking machine, and so rightly given pride of place - in the form of Peter Gethin and his Church Farm Racing's example - on the front cover of Nick Geogano's 'Encyclopaedia of Motor Sport' published around the time of the type's heyday.

Not happy days for Garrie Cooper at 15 seconds in -

http://www.youtube.c...player_embedded

He went on to recover his health enough to conceive and build the ground effect MR9 at least!!

The above you tube footage is part two of the clips on this Roaring Season page - http://www.theroarin...rmula-5000-Cars

Apologies if the Roaring Season footage has been posted here before - the extended racing footage is more than good enough to warrant a second look if I am repeating it!!
