Rolls-Royce Made A Valveless V12 That Could've Given The Spitfire 5,000 HP!

December 21, 1944. A test house in Derby. On the brake — a V12 of 26 litres. No inlet valves. No exhaust valves. No camshaft. 36,000 exhaust pulses a minute, heard five miles away. Six were built. None ever flew. All six vanished.
Nine years earlier, a London committee asked a question nobody dared ask. What happened?
This is not a story about dogfights or ace pilots. This is a forensic audit of the most powerful piston engine ever built for its size — and the part somebody took out.
📊 Inside this documentary:
Why Britain ordered an engine built to waste fuel
How one cylinder on a bench pointed to 5,000 horsepower
Why a Spitfire sat at Hucknall with a wooden engine in its nose
How Germany was already flying a valveless engine over England
Why a Scottish firm won its patent case and died of the legal bill
How a five-shilling lunch in a Lancashire hotel ended it

Already with "only" 1200 HP the Spitfire was a monster at low speed. A pilot had to be very careful and experienced to prevent the engine torque to flip the one aircraft upside down if full power was applied too quickly during take off.
But it was accepted and most pilots got used to it soon enough, although it did kill some. It was war, "killed in action". But with 5000 HP the torque would have been a pilot killer.
