The first twin-cam article? - Tony Griffiths - 23-01-2025
The first twin-cam article? The Light Car, March 20th 1936. This was a two-page spread that I've digitally restored and joined as a single A3-size page.

Thank you Tony, looks like a perfect addition for my new workshop just completed yesterday. Just the poster we have enough sevens

8,000 rpm on a 50 / 50 petrol benzol mix gave 95 bhp, a top speed of 125 mph and 7.5 mpg.
10,000 rpm on an alcohol / water mix gave 120 bhp, a top speed of 138 mph and 3.5 mpg.

I'll take two of the latter, please.

So excuse my ignorance but at that fuel consumption how on earth did they race it without a fuel stop every few laps?
PS it's blo**dy windy up here...

10,000 rpm was used for sprints, the 8,000 rpm for racing. Tank capacity, 25 gallons.
So, for racing a distance of 190 miles approx.
Unlikely in a race they would be using 8,000 revs all the time so, say, 200 miles duration.

When lining the racing cars up for the lobby display at the Centenary event, I sat in one of the twin cams and steered as it was wheeled into the building. It is tiny!! Bert and his chums have my huge admiration for having the sheer nerve to drive them at those speeds…

And the earlier 'Ducks' at 110 mph - when we had one here the then owner Grant Cowie did the 1/4 mile in around 14 seconds.
Talk about tiny - standing over the 'Duck Racer' in the pits I doubt I could fit in the cocpit let alone get my size 10s on the pedals.
Amazing (and brave) drivers in the works teams.

I've seen a very similar 3 page article in the Autocar dated March 20th 1936 - same date -official press launch?
