It is not just merlins that are put in cars. I have attached two photos taken from this years Shelsley Walsh hill climb, the first is the Napier bentley – 24 litres of Napier lion ( well to be precise, it has a Sea Lion crankcase), and the Hispano-Delage which has a 27 litre Hispano 12Y. I can highly recommend visiting one of the many VSCC meetings where the aero-engined specials are racing – some of the Edwardian cars with Curtis OX-5 V8’s have to be seen to be believed, such as the third picture taken in 2002.
Of course there is also the DH Riley with a Gypsy major I believe – all of the above bar the Hispano have been driven on the public road I believe

I am sure I have seen this photo in ‘Wings on my sleeve’ by Captain Eric Brown. He is sitting five from the right in the front row. RAE Farnbourough test pilots and ‘boffins’ from the Aeronautics development flight? I can find out more when I get home this evening

Quote “We don’t put Wright 3350s or P & W 4360s on our Sea Furies because we are trying to cause trouble, we do it because we would rather see the airplanes fly than sit on the ground. And that’s exactly where most of them would be if we were dependent on flying behind the Centaurus.If I could have a reliable Bristol Centaurus with a Dowty Rotol prop on my plane I would do it tomorrow, but the fact of the matter is I might as well wish for the moon. “

Well said. Most of us here don’t complain here about Spitfires flying with the “wrong” mark of merlin of griffon, or even of planes like the wonderful Hawker Cygnet replica flying with a more modern plant – it is much better to see them flying than not at all.
