Why was the QF 3.7 Ram Horsepower Doubled?

The “seems possible” was in relation to the engine being wrong and actually being the 450 horsepower diesel version.

Sorry if it wasn’t clear.

A similar event occured with the Churchill in Irish service, where they tried (and apparently succeeded) to fit a Merlin engine into it. The British also did the same with a Crusader with a Meteor engine.

The Merlin engine (from a Seafire) produced 1,230 hp, I have no clue how the transmission handled that (perhaps the engine was derated) but it seemingly did. The Churchills original engine only produced 350 horsepower.

The test Crusaders had a Meteor engine producing 510 hp in a tank weighing only around 16 tonnes, this give it a top speed of in excess of 50mph (80kph).

I have no idea how they managed to do it in the Crusader or Churchill, but persumably if it was possible for them, 800hp for the ram could also be possible.

those engines were extremley downtuned. to save fuel and gearboxes as well as the stress of a 25-40 ton tank compared to a spit

The Meteor engine was supposedly kept at 600 horsepower in the Crusader.

Presumably the Merlin engine was downtuned, but we don’t really know by how much

edit. Documents say the Merlin was actually rated to 510hp for initial tests, which is still a significant upgrade over the original 340hp engine

these were very early marks of meteor on the British crusaders so weren’t full power

Ed francis from armoured archives shared some good info on it in this thread

I just had a read through there, as I corrected they were set to 510 horsepower for the Crusader, someone else seemed adamant there was a 1000 horsepower version made but I dont see any valid proof of it

At the end of the day I think the gaijin should just follow the documentation for the QF. Ram, its clearly written there and seems to be historically accurate. Does it bring into question how it mechanically could have worked? Sure, but many vehicles in war thunder aren’t modelled in ways that would work in real life.

that guy is quite a delusioned soul with the capabilities of British tanks ill keep it at that.

I mean engine swaps can be bolted to whatever with adaptor plates its just a matter of practicality

I say bring them into the game, I would love to see a Churchill that can actually move. I think this is getting off topic though

How many QF 3.7 Rams were even produced?

Sounds almost like it was just a test vehicle.

Only one prototype was built and tested.

Well, I think I found my answer. From the old-wiki.

Hellcats aren’t that bad lol, even they don’t weigh as much as a tank

Oh I’d give anything for this…

Yeah, who says primary sources are always going to be right? It was a Wright Whirlwind, same as every other Ram, almost certainly.

at least its a source from the nation that made the thing. so many vehicles have weird mistakes from being based on soviet guesses so at least its something

More Canadian buff, great!

You would have to be pretty stupid if you were tasked with making a report on an army project and just happened to not notice that the engine developed 350 more horsepower than it should and didn’t bother to double check.

Put a 600 hp engine in the Churchill. let see if it can hit 30.
