What model or models of WW2 Rolls Royce Merlin Engine is the Rover Meteor based on?
My question is, what model or models of the famous Merlin aviation engine is the Meteor tank engine based on. I realize the Meteor didn't have a 2 stage super charger, normal petrol/gasoline and used heavier materials than it's Merlin brother. As well
The Meteor engine was originally a de-rated Merlin III. If I remember correctly the engine was de-rated to around 600 HP from 1140HP of the Merlin as it did not have a supercharger and it was running on pool petrol.
The Merlin III ran on

Also going to clarify the connection between the Rolls Royce R engine and and the Merlin, as it's not a clear cut statement
Nothing like the sound of a #Merlin engine by #Rolls Royce
Is there a better sounding engine than the Rolls Royce Merlin mounted in the front of a Spitfire?
I really think a strong case could be made for saying the war in the air was won by the Rolls-Royce Merlin Engine.
RT @: It's also Battle of Britain Day. So let's watch Battle of Britain and listen to the lovely rumble of the Rolls-Royce Merlin Engine!
