Pipes galore.

Talking, below, about all those cylinders etc., what do you make of this engine from Repco?

A while ago now.

Paul Halstead was building this 16 cylinder supercar.
I wonder how that's going.

Great photo!

Getting comfortable in a Willaston carport.

The ex-Allan Davison drag car has settled in nicely and looks the goods on its original wheels picked up in Canberra as it awaits its LONG TERM restoration.
It will be due to have a 302 Windsor as it used to race and possibly dispense with that horrible scoop that it never raced with.

This is how it used to look in its VooDoo and Challenger liveries.
Now that Dave has sold it to Greg it may give him some time to  get stuck into one of his 3 Buchanans.

An interesting course of events.

To me there is no doubt that the car really is the Gp.4 chassis number 2263 resurrected as  a road car at a later date. Similarly the Alan Hanns, Steve Webb or Ranald Maclurkin race Nagaris are still B8/57, B8/07 and B8/38 despite now being turned into road cars. We have also seen pranged Nagaris and the odd Mk.7 re-emerge with the Fibrecar touch but that's a long time ago now. Where it gets really naughty is something like the knobbly Lister that popped up in Australia and representing itself as one that already exists in the UK.

OK all you drag racing historians!

A recent request from a lady on our facebook page:-

Hi I've recently come to own a Buchanan body and I'm hoping you may be able to point me in the right direction for more info on it?
What type of info?

Anything. Type of chasiss Running gear. How to identify exactly what it is and was
We were told it used to race as Tantrum

PLease help.

Virtual? Does this mean the car doesn't really exist?

Holden showcases radical Bathurst time attack concept

From Tom Howard via SpeedCafe.com
GM Holden has designed a radical time attack concept race car to coincide with the 50th anniversary of the marque’s first Bathurst win in 1968.
Conceived by GM Holden’s design team, the car was developed entirely virtually, using sophisticated simulation technology and driven by the world-class expertise within its Melbourne design studio.
Holden has focussed the design around achieving pure one lap pace with the company claiming the concept could theoretically lap Mount Panorama in 1:29.30s, more than 30 seconds faster than the current outright lap record, and reach speeds of 480km/h.
The entirely carbon fibre chassis is powered by four 254kW electric motors which could produce 1340 horsepower.
It was developed with technical input from GM Holden’s engineering team and the final design was validated with a digitally-printed 3D model.
“The technology we employ today has transformed the way we design cars,” said GM Holden’s Design Director, Richard Ferlazzo.
“We have the ability to simulate a car’s appearance, technology and dynamics in convincing animations, which enables us to deliver better designs in a shorter time.
“A large part of our work is Advanced Design and we use this technology to develop concept designs for our parent company, General Motors.
“This concept is a digital advertisement for the advanced skills, capability and technology of the GM Holden team.”
Fans will get to see a virtual lap being completed by the car during Saturday’s broadcast from the Supercheap Auto Bathurst 1000.
This weekend’s race sees Holden celebrate a maiden Bathurst victory delivered by Bruce McPhee and Barry Mulholland in an HK Monaro back in 1968.

Not to be missed.


Celebration of an Australian icon - 50th Anniversary of the Bolwell Nagari at VHRR Phillip Island Classic March 8-10 2019.

We are in a great time for Bolwells, the first Bolwell Car Club was established in 1968 and we are celebrating 50 years of the club, plus, next year we will be celebrating 50 years of the Bolwell Nagari. It has become a focus for all things Bolwell - not only the Nagari. So we are keen to hear from anyone that has an interest, owns a car, been a past owner, or maybe had a friend or family member own one, maybe they worked on them, maybe you know where one is.

Why highlight this event early? Well, we understand in these busy times that people may need some time to organise - potentially a car has been in the garage for a few years too long - well now is a great time to look at getting the car out and join what will be one of the largest contingent of Bolwells ever assembled!!! It's a celebration, not a fashion contest, so bring your car so that you and others can enjoy it. We have cars already coming from all over Australia to the event. The location - Phillip Island Historics, March 8-10 2019 and Bolwell will be one of the "Marques of the Meeting". As such there will be "once in a lifetime activities" available for the Bolwells present to participate in (Premier display areas, display laps on the track, photographs on the track, chance to meet Campbell and Graham Bolwell, there may even be a new model Bolwell on display, cheaper entry, etc. etc.). So dust off your car, your memories, your old photos and lets really enjoy the event together. If you are interested or thinking about attending please email bolwellcarclub@gmail.com . Remember it's not only owners that will enjoy the event but all those that have experiences to share. We look forward to hearing from you and seeing you at the event.
