1908 M.A.B Saunders Special powered by a 1918 Packard-Liberty V12 aero engine, to build a facsimile of a pre-1910 racing car, and it was 1 of 28 entrants in the Outback Stage of the 1988 Australian Bicentennial World Rally, and the first Targa Tasmania, in 1992

weighing a not inconsiderable 380 kg itself, it produces around 1000 ft/lb of torque, 400 brake horsepower and revs to just 2000rpm, enabling this M.A.B Special to cruise comfortably at 80 mph, with a top speed of around 100 mph.

Pur Sang is a group of artisanal enthusiastic mechanics and designers, with endless ideas including building aircraft engined specials in the style of the post-WWI era. What goes on at Pur Sang is amazing.

In the end, though, the process is less significant than the people, who are – and realize they are – privileged to work in an environment that creates marvelous objects. Yes, it’s a job, and at 5 o’clock they head out to their families but the pride and satisfaction they take from what they do, and in doing it well, is tangible throughout Pur Sang, from Leonidas Anadon, Pur Sang’s padron, to the second generation assembling cars and gearboxes with their fathers.

Il Drago Ruggente, an Isotta Frachini 27 liter, V12, 800hp engine came from a Caproni bomber, frame of a Delage. The plane came to Sweden in December 1940 and was scrapped in 1943.

An oil change is 55 liters of 20/50 zinc rich oil. Imagine how long it takes to empty 55 bottles.... and that is just the one oil change. 8 gallons of gas per 6 miles driven. 0.75 mpg...

After a long interview, so it was time to start. I jump up in the Drakensberg. Starts petrol pump and ask Magnus open air valve, while I start spinning the starter magnet and waiting for a bang when kicks off the engine, but it is not! There was only a small puff of smoke, and that was all. Ungrateful Drake, with all the care it received prior to the start.

We took a quick decision to pour in some extra gasoline directly into the carburetors. It may take a real shot (6th 98 octane with wormwood), in order to get a grumpy old man. Speaker asked what happened and I explained that he is a bit grumpy and need a shot, all older men need to get started. He was not slow to instämma- the Yes Indeed!

Ten minutes later it was the pressure of the air tanks and into the bloodstream at the top! And so we were finally ready to start again. Before we started, so I said to Bo to check that no one is standing behind the Dragon when we kick off. Partly because the smoke, but also for the flames. Magnus opened the air valve and I started the petrol pump and started cranking the starter magnet. 2 seconds later so pulled engine running noise and bong. Damn the smoke from the exhaust pipes. Bosse who went behind the vehicle to warn the audience completely disappeared in the smoke.
