Kapunda - week 41

Falcon GTs are a bit thin on the ground in Kapunda and XR GTs even more so but look what we find 2 doors up the street from our place.

Flashback, over 40 years.

6 Hour at Winton.

The Burdon Mark 7.

....and the Wall Mark 5.

V8 Perana for sale in Queensland.

and reasonably priced IMHO.

Leo Kusters, the latest.

Leo's Camaro hits the track.

Tech session from Grant - Tips on Brake Bias

Obp Tech-Session Top Tips and Information on Brake Balance / Bias Bars

As I have mentioned before your aim is to design your brake system so you will obtain maximum braking efficiency from all four wheels. Under braking weight is transferred to the front of the vehicle so that means your front tyres and the front brakes will be required to do more of the work.

In order to allow you to fine tune your brake balance from front to rear you will require bias / balance bar.  To install the bias / balance bar it is necessary to use a dual master cylinder set up.

The bias / balance bar functions quite simply by altering the fulcrum (pivot) point on the rod that connects to the push rods that operate the front and rear brake master cylinders. By moving the fulcrum point you are able to control and change the amount of relative force that is applied to each of the master cylinders. This bias / balance application when correctly installed will give you the fine tuning you require so the front brakes will lock up just before the rear brakes. This professional brake system set up is essential to be competitive in motorsports.

SOME TOP TIPS ON ADJUSTING BRAKE BALANCE

1.   Changing the ride height of the car changes the braking characteristics and generally will cause the brake balance to be altered.
2.   The balance bar push rod should be adjusted so that the balance bar is perpendicular to the master cylinder push rods when the pedal is released. When the pedal is released, both push rods should be pulling against the retaining washers of the master cylinders. If the system is not adjusted correctly the push rod can advance the caliper pistons enough to cover the bleed holes in the calipers and this will cause the calipers to lock up as soon as they get hot.
3.   The only way to adjust the brake balance / bias assembly is by changing the fulcrum point between the master cylinder push rods and the pedal. You can’t adjust the brake balance proportion by changing the length of the push rods relative to each other.

Kapunda - wek 40

Chris P had her beautiful Mustang out for the street party the other week.

Wasn't a bad roll-up.
One of my favourite cars there was this one.

It's Glen S's Hudson Pacemaker. He's got a couple of Commodores for spares. The reason it's not quite as clean as when Glen left home is because, like heaps of people around here, he's a farmer and lives down a dirt road. Here's a typical road........

Gibbo's photo.

B8/3 - just a bit more.

Memories of B8/3 began flowing a few months ago when Ross McConnell dragged out a few photos of it from 1970, taken at the Bolwell factory, such as it was back then.

Here it is with its fixed side windows and sporting the pre-Bolwell Nagari wheels.
When B8/5 arrived in Adelaide soon after this, it too had the fixed windows but had the Bolwell mags (the rather heavy first version of course).
Pete published the photos in Slipstream and added the amount of history that most of us know.

There are a few gaps that maybe a reader could fill, like how did it get to Queensland. I remember Ray Moore and Peter Cowen, both Brisbane Nagari owners back then, talking about an elusive red Nagari that nobody ever got close enough to identify.
Pete also published these two write-ups.

Then Colin presented this picture of Dennis Walford's bucket running against a Nagari, presumably B8/3.

I've been scanning Calder Dragway entries and results the other day and discovered this snippet.
         Calder Dragway 3.5.70 P. Law, Bolwell Nagari  16.43 secs.  87.63 mph.
P. Law is Peter Law from CMA Engineering who built the drag engine for the car. The times tell us that this was pre the big motor which would have to be the case as the car was only delivered literally days before the event.

GTEs and BCCA.

BCCA in South Australia has had a number of Scimitars in the club over the years including a V8 one. The longest standing one is this one of Glen's and that's its former owner sending it on its way at a checkpoint in Robertstown.

This is not unique to SA though. Here's a Victorian one in the motorkhana at the Bolwell Easter at Nyah West.

We know whose these are.

Favourite battles of the past.

Mick and Bernie. Enough said.
Photo nicked from the Mallala page.

Help wanted - 240Z

See this thin chrome plastic surround. I've been scanning all the parts books and I can't find what it's called. The next step after I find out is where do I buy one?

Kapunda - Week 39

The only form of public transport in Kapunda.

Doesn't run all that regularly either.
