Vintage Thing No.46 - the Austin-MG special

Image
I was unable to go to the VSCC Wiscombe hillclimb this year so by way of compensation have been reviewing the photos I took last year. This the Austin-MG special built and raced by Brian King. It's essentially an Austin 7 engined fitted with an MG ohc cylinder head but there's a bit more to it than that. I like the way it's been fitted - and supercharged. Most MGs of this era had a vertical shaft drive that doubled as the dynamo. It was notorious for getting covered in oil and not producing any sparks. For his Austin-MG special Brian chose a duplex sprocket chain drive. With all that going on the front of the engine most normal people wouldn't have known where to put the blower but Brian extended the tail end of the crankshaft rather than the nose and moved the flywheel outwards so that he could take the supercharger drive inboard of the clutch. The components date back to 1930 and 1934 so long before Austin and MG were bedfellows in the overcrowd...

Vintage Thing No.4.1 - The supercharged two stroke Trojan engine

Image
At last - more info including a picture of that weird engine I found backalong A chap called David Pickard has sent me a link to the Trojan Trust website where there is a reproduction of an article published in the October 1946 issue of the Commercial Vehicle User's Journal . What wonderful names we used to have for our magazines! And the engine featured in this article appears to be the same supercharged engine that I found in an old copy of The Motor Vehicle by Newton and Steeds. This engine powered the 15cwt & 25cwt Trojan vans after World War II and in general terms the Commercial Vehicle User's Journal matches the technical description provided by Newton and Steeds - to wit 24bhp and 1186cc (65.5mm x 88mm). Although it is a four cylinder engine, it has six cylinders - four of them paired in two split cylinders that share a common combustion chamber. But the most interesting feature of the design is an inlet rotor in the head of the charging cylinders. This ...

Engine Punk Litmus

Image
There's something interesting going on across the internet at the moment. Somebody else has picked up the engine punk ball and is running with it. Engine Punk Litmus is a blog that suggests examples of the engine punk aesthetic and I have to say that so far - having coined the phrase in a tongue-in-cheek effort to pigeonhole my own brand of sci fi fantasy writing - the suggestions so far are pretty much what I would call engine punk. But what do other people think?

Werrington Park Hillclimb - 2-3rd May 2009

Image
I was running late on Sunday but still manage to make the Werrington Park Speed Hill Climb just north of Launceston in the border country between Cornwall and Devon. In dry and sunny conditions but with a surprisingly chill breeze there were many fast runs and class records were being matched, if not actually broken. And the surroundings were just magnificent - the artist in me revelled in the colours and the light conditions. The course at Werrington is 1200m long and one of the longest hill climbs in the UK and there were almost 100 cars present, many of them featuring double drives with friends and family competing against each other in the same car. Held over two days, the event attracted competitors from as far afield as Birmingham and constituted a round of the 2009 Cornish Speed Championship, the 2009 Bridge Tires and Wheels Motor Sport ASWMC Hillclimb Championship and the 2009 ACSMC Hamilton classic hillclimb championship. I spent a very pleasant afternoon...

Vintage Thing No.37.1 - MAE head (Modified Anglia Engine)

Image
Following my recent amazement at discovering Ford Modified Anglia Engine head at Adrian Booth's workshop, not only have I been in contact with the owner of such a device (more on that later) but I also stumbled across this illustration of one in a most unexpected place. This is a scan of a black-and-white illustration from Dave Vizard's book, How to modify your Mini. This work was subsequently expanded to embrace all A series engines, whether fitted to a Mini or not, but whereas the later book concentrates purely on the engines, this volume also covers suspension and braking. In terms of modifying Minis, bigger engines have always been popular and in the chapter that I find most appealing a number of big for long stroke Mini engines are proposed. But right at the end of this chapter is an engine transplant involving a kit produced by Richard Longman allowed the fitting of a Ford cross flow engine. A series engines can be enlarged up to 1600cc but this is a very time-consu...
