The Chamberlain Eight’s four cylinder, eight piston, supercharged, twin-crank, two stroke engine left an unforgettable, ear-splitting impression on all who saw it at the 1978 50-year anniversary of the 1928 100 Miles Road Race aka Australian Grand Prix at Phillip Island.

What I hadn’t fully appreciated in fulsome fascination for a car which was at the cutting edge in its engine, chassis, suspension and front wheel drive – all of which were out-there in 1929 – was the length of time it was first fitted with Indian motorcycle engines. It first saw the light of day with a Daytona unit and then an Altoona. It was only when Bob Chamberlain travelled overseas that he handed the car to his brother Bill, who built and fitted the Chamberlain engine circa 1934-35.

The publication of a good photograph of the Altoona racing engine taken by mechanic Fred Pearse, and published on Bob Williamson’s Old Australian Motor Racing Photographs Facebook page by Peter Reynell, piqued my interest.

It’s unsurprising that the Chamberlains chose an Indian engine for their beloved Beetle, from the businesses incarnation Indian was innovative and used motorsport to develop the product and build their name, they finished 1-2-3 at the Isle of Man TT in 1911.

John Medley picks up the story (in the article linked above) “The car’s first engine was a big-valve Daytona Indian motor cycle unit. In this form, the road registered car covered thousands of miles but trouble was experienced with the valve gear.”

In April 1920 a 998cc side-valve, Vee-twin Indian Powerplus ridden by James McBride achieved a top speed of 99.25mph on the Daytona Beach course. The race versions of the Powerplus motor subsequently became known as the Daytona, throughout the 1920s various configurations of factory racers were built around this record setting engine.

The Altoona Speedway was a 1.25 mile board track at Tipton, near Altoona, Pennysylvania which was home to the national championships in the 1920s, winning there was a big deal.

Indian’s designer, Charles Franklin – Irish road-racer and Brooklands tuner who discovered the ‘squish-effect’ in combustion chambers 10 years before Harry Ricardo – inherited a new 61cid side-valve engine from his predecessor, Charles Gustafson, which he turned into a race engine (there were also eight valve and 45cid variants) to take on the best at Altoona. The engine incorporated timing gears and crank carried on self-aligning ball-bearings, two oil pumps, removable heads and twin up-draught Zenith racing carbs.

With the new engine – still mounted in a 1920 spec board-racing frame – Curley Fredericks lapped Altoona at 114mph in a July 1926 race, the highest speed ever recorded on a circular board track. On Hampshire’s 1.25 mile board track that August he did 120.3mph, the fastest speed ever recorded on the boards. These unique race venues vanished soon after when the sanctioning bodies and manufacturers withdrew their support given safety and maintenance issues, so Frederick’s record still stands.

Of course it wasn’t long before Indian applied the Altoona name to its 1926-28 factory side-valve racers. The engines were used in disciplines other than board racing, including hillclimbs and drag racing

To promote the opening meeting of John Wren’s Melbourne Motordrome (aka The Murder Drome and Suicide Saucer on the Olympic Pool/Collingwood FC site) in November 1924 the promoters imported four top US stars and their bikes; Paul Anderson and Johnny Seymour on eight-valve Indians and Ralph Hepburn and Jim Davis on Harleys.

Ultimately the Harley duo rode borrowed Douglas twins when their machines failed to arrive on time. In the solo-final Seymour and Hepburn dead-heated. The Indian riders had a successful tour albeit Seymour (later an Indy racer) broke a leg at one meeting. Among his successes, Anderson won the 10-Mile Solo under-500cc NSW Championship in January 1925, and did a record-breaking 125mph over a half mile on Adelaide’s Sellicks Beach. Anderson won so many scratch races on the Melbourne Motordrome that the promoters abandoned scratch events and ran handicaps!

When the Chamberlains were looking for greater performance they turned to “A motor (500cc, eight-valve, V-twin) of novel design, using an Altoona Indian crankcase, originally used by the famous American, Paul Anderson,” The Sun, Sydney reported.

“The cylinders were scrapped and 588cc overhead valve Norton cylinders and cam gears and two carburettors were fitted, and the compression ratio raised to 10:1.”

John Medley continues, “The car now became quite competitive, particularly in sprint events, easily holding the Wheelers Hill (in outer Eastern Melbourne) record for example. It ran in the numerous sprint events run by the Light Car Club of Australia, Junior Car Club and the Royal Automobile Club in Victoria during the period, as well as circuit races at Aspendale (inner Melbourne bayside suburb) and Safety Beach (holiday destination on Melbourne’s Port Phillip Bay).”

“Entered three times for the AGP at Phillip Island, the car was not successful. At the first attempt (1931) a piston seized due to the alloy being unsatisfactory, so the car did not start. By the following year the Chamberlains had made their own pistons from ‘Y’ alloy and the car completed practice without any troubles. In the race it only lasted 3 laps, when a crankpin broke.”

“Bob had trouble recalling a third attempt at the Island but checked his records and found that the car was indeed entered and listed as supercharged, although he is sure the car did not actually race in this form. Bob says that the blower was fitted to the Indian motorcycle engine and the compression lowered in the hope of improving big-end bearing life. It didn’t work out that well but this two-cylinder supercharged engine powered the car at several meetings at Melbourne’s Aspendale Speedway as well as a number of hillclimbs, with some success.”

“Then, in 1934, in Bob Chamberlain’s first attempt at Mount Tarrengower, the car crashed not too far from the site of (Australian Hillclimb Champion) Peter Holinger’s Holinger Repco V8 1977 accident. It has been said of Mount Tarrengower that if you make a mistake you have to fight for airspace with the pigeons. Bob Chamberlain was saved from that battle by a stout tree, which he scored at top speed just beyond the finishing line.”

It is at that point that Bob Chamberlain departed overseas and Bill Chamberlain set to work on construction of the Chamberlain 8 that Bill Thompson enters the picture.

Thompson had won the Australian Grand Prix thrice, aboard the same Bugatti T37A in 1930 and 1932 and racing a Brooklands Riley in 1933. He was regarded as the best of his generation. By 1935 he had retired from road racing, but was perennially short of cash so decided to compete in the nascent sport of midget speedway racing, an activity which dovetailed nicely with his recent appointment as managing director of National Speedways Ltd.

In need of a car, Thompson convinced Lanes Motors – Melbourne dealers of Morris and MG amongst others – where he was head of the MG department, that midget racing would provide great exposure for their products on tracks at Sydney’s Showgrounds and Wentworth Park, Penrith, Newcastle and the Olympic Park Melbourne.

He concepted his ‘No 1’ machine, the Altoona Indian powered Lane Special to be powered by the light, potent, proven Altoona Indian-Norton engine. Built in Lanes’ racing department in South Melbourne the car “has a clutch and speed (sic) gear box and the chassis, steering axles, brakes etc built up from Morris Minor and MG parts,” The Sun recorded.

Australian international motorcyclist/master mechanic, Wilfred ‘Bill’ Balgarnie – who had represented Australia at the Isle of Man aged 22 in 1934, finishing 13th on a Velocette 350 in both Junior and Senior TTs – was also involved in the construction of the car. Balgarnie accompanied Thompson as riding mechanic in two of his AGP wins and in many of his major races.

Balgarnie worked on Bill’s car and on a P-Type MG which was to be adapted for midget competition and raced by him. The 845cc engine was retained and modified, while the body was streamlined and lightened, the engine/transmission lowered, and mandatory 12-inch by 4-inch wheels fitted.

By August ’35 Thompson’s equipe also included Bob Findlay’s Midget. Balgarnie had performed so well in the P-Type Spl that Thompson acquired a better car for him, with which he was formidable throughout 1936-37.

The Sun reported in November 1935 that Thompson had a successful season (February to May) in Victoria but “has been disappointed with the Lane Special’s performance since its arrival in Sydney.” Thompson consulted with “famous speed merchant Ron MacKellar (Sydney Ford dealer and racer/engineer)” to dismantle the Altoona Indian engine to recondition it to find the 70bhp of which the motor is capable.”

When fitted to the Chamberlain “it has been credited with lapping Phillip Island at 78mph, “only 6mph below the official lap record. It was timed over the mile there at 103mph.”

While Thompson’s speedway record is said to be ‘undistinguished’, I’d like to record his results if any of you have ready access to Kent Patrick’s biography of Thompson. Time I bought it.

Finally, what became of that rather special engine I wonder…

Etcetera: Bill Balgarnie…

I was aware of Bill Balgarnie as a talented mechanic/riding mechanic but not his own record as a racer on two wheels and four.

Some Troving (Trove is an Australian newspaper digital archive) reveals that Bill was as much of an ace in a car as he was on ‘bikes, including countless midget wins, victory in the 1937 NSW State Midget Championship in front of 25000 spectators at Penrith and much more.

A Western Mail, Perth article about him published in March 1951 helps fill in the gaps, I’ve paraphrased it and added some other tidbits.

Born of parents who lived in Bowral, he first became interested in motorcycle racing when he left school in Sydney, competing in road races around Sydney and at Bathurst.

By 1934 he was one of the leading riders in NSW and was chosen to represent Australia at the Isle of Man. When he arrived in the UK, Velocette made a 350cc bike available for the races contested by 80 riders including the champions of England, Germany, Spain and France.

While the going was tough, the bike performed faultlessly and he averaged 74mph to finish 13th, and first visiting rider home. In so doing he won The Motorcycle Visitors Cup and received a replica of the Senior TT Trophy for recording one of the races’ fastest times.

The Junior TT was held the following day, “A terrible day, very foggy and wet and on parts of the course, visibility was very limited. I must confess I was pretty anxious about that ride, but again the machine went without a hitch and averaged about the 70 mark.” He was again 13th on the 350.

Afterwards he toured England for several months and for a period received specialist training at MG. He visited Brooklands and did a trial lap on a borrowed bike at 97mph, just missing out on the Gold Star awarded for laps of 100mph and over.

Then it was off to the Belfast TT, then France for an “international car race”, and finally Milan for a tour of Alfa Romeo before returning home to Australia late in 1934.

Balgarnie was immediately back in the fray, using his tuition at Abingdon to prepare and act as riding mechanic aboard Bill Thompson’s Lanes Motors entered MG K3 Magnette in the Centenary 300 at Phillip Island, the longest race for “purely racing cars” in Australia in January 1935.

In a winning position from scratch, and on-the-hop, Thompson sought to pass another competitor on the outside at Heaven Corner on lap 12, slid, then ran out of road as he corrected, crashed into a scoreboard and rolled. Thompson escaped with facial injuries but Balgarnie’s chest was crushed, “which kept him from work for several weeks.” The perils and stupidity of allowing riding mechanics…

By 1936 Balgarnie was back in Sydney to race and running a servo in Rushcutters Bay, in addition to “dabbling in wrestling to develop his strength”!

The Australian Midget Car Championship and Five Miles Amateur Car Championships followed at Penrith in April 1937, and shortly thereafter a major accident when a fellow competitor stalled right in front of him at the Sydney Showgrounds. “It was too late to avoid him, I crashed into his back axle, looped the loop and turned over three times. After that I can’t remember a thing, I was out to it for three days.” He recovered quickly despite a cracked skull, broken arm and injured thumb.

Showing that he wasn’t at all phased by the accident Balgarnie won his class driving Ron MacKellar’s MacKellar Spl s/c at Waterfall Hillclimb in late August.

In February 1940 he married Pauline Laidley at Double Bay, the bride was given away by Ron Mackellar in a large wedding. In the early 1940s he joined the armed services but returned to competition with a couple of hill-climb drives aboard the Chamberlain 8 in 1946.

By then employed by the Chamberlains, Balgarnie was promoted to the position of works manager for Chamberlain Tractors whose manufacturing facility was in Perth. At the time of the Western Mail interview he lived in Dalkeith Road, Nedlands.

Balgarnie Snippets…

In the 1930s, the Midget racing season ran from November to May

Balgarnie rebuilt the Jack Jones/Mrs JAS Jones Alfa Romeo 6C 1750 Zagato SS after it was “completely burned out” in 1933. “Used as a hack for many years,” Jack Jones set second fastest time of the day in the May 1937 Canberra Speed Trials at 102.2mph over the standing quarter mile, “Which speaks well for the skill of the mechanic who rebuilt the car and was mainly responsible for its performance in Canberra,” the Sydney Referee reported. Frank Kleinig’s supercharged Miller powered Kirby Deering Special was quickest at 116.9mph.

In December 1935 Balgarnies speedway midget was reported to be equipped with “BSA overgear and an Altoona crankcase.”

In a 15 August 1935 Sydney Referee news item about the upcoming 1935-36 “season in Melbourne there will be at least 24 drivers available when the Olympic Park track reopens again” with the “big shots” among them “Bill Thompson, Bob Findlay, Bill Wilcox, Barney Dentry, George Beavis, Les Gough, Ern Day, Fred Curtis, Joe Parmeley, Bill Allan, Bill Balgarnie, Arch Tuckett, Arthur Higgs and Sid Gowar.”

Tailpieces…

Now, where did I put my hammer? The engineering and construction challenge, and ongoing maintenance, were considerable! Dated by Getty as 1950, but lets call it 1922.

Altoona Speedway was built at Tipton, 20km north of Altoona, Pennysylvania as a 1.25-mile timber-oval with corners banked at 32-degrees, by entrepreneurs Jack Prince and Art Pillsbury.

It operated between September 4, 1923 and September 7, 1931, then was destroyed by fire in May 1936. In 1935 an oiled-dirt oval was built on the site, then post-war, a quarter-mile track opened on the infield, it held meetings until 1952. Industrial buildings now occupy the site.

Finito…
