Why was the QF 3.7 Ram Horsepower Doubled?

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.

I read military reports for a living. That wouldn’t even be the sloppiest report I read TODAY.

The reason I’d say this is likely a mistake is that the alternative is less likely. The test report itself is focussed primarily on the gun, not the vehicle performance, as I read it. I doubt the vehicle moved much if at all and the testers were obviously gun guys, not tank guys.

If it was accurate, and we know this was a bodge job done with a spare tank and a gun lying around, probably by bored Canadian Army mechanics, not a prototype with a lot of company design effort behind it, that means the creators found an aircraft engine from somewhere (because there were no Cyclones manufactured to fit to tanks, at least in Canada at this time) one twice the size on terms of displacement of the one that had been in the engine compartment originally, welded it in there, and no one else noticed that twice the horsepower for a vehicle of basically the same weight as an original Ram led to any difference in performance.

We’re talking basically an M6 tank engine (57t) on a 32t vehicle. It would have been speedier than an M18 Hellcat. So yeah, I think someone else would have mentioned it. I’m not ruling out soldier ingenuity but it seems pretty far fetched.

Also, correcting something said above, several 3.7 inch Rams were built in Canada. Only one was shipped overseas. Amazingly sometimes the WT old wiki isn’t a great source either. :)

Good write up here btw: OQF 3.7" AA on Ram Mounting - Tank Encyclopedia

I think it’s pretty obvious when you read it that this engine identification was a mistake by the British Anti-Aircraft School evaluator. (Psst… The AP round for it is also not a thing that really existed btw. Also the top armour on the one prototype shipped to the UK was made of wood).

Even if this change gets reversed at some point, it sure is fun while it’s lasting lol.

I’m a big fan of more Canadian content in War Thunder, but they done the 3.7-in Ram SP the way it was brought into game, they kinda did it dirty.

We’ve already seen the M44 with a 105 mm HE being quite successful at 4.0. If they had brought the Ram SP in game about a BR lower with its actual ammo loadout of HE, HE-VT(!) and shrapnel, just more high velocity and hence accurate than an M44 (and its real horsepower) it might have worked out pretty well for the Brits.

But they’ve always done silly things with Canadian armour in this game, just a string of one weird content decision after another, so I’m kinda resigned to it now. (Honestly a lot of their low-tier armour content additions have been kinda… off this last year, so it’s not just Canada anymore… I don’t think the game needed six M44s, the double Skinks, double Rams, double Panhards, don’t forget the APHE vote… just seems to be trying to please and keep their players now more than make a better balanced game at low BRs. So if they found a sketchy primary source that says 800 hp instead of 400 so they can justify a Canadian Ram SP driving around like an ATV with seven people onboard hilariously hanging on for dear life, hey, why not?)

Was close

Edit: Have raised issue with Gunjob to have it reopened, as it was closed because they didnt want to add proximity fuse for it.

Didnt want to add proxy fuse and yet at the same br both the russians and germans have both anrange finder and proxy on their equivilant

The issue with this evidence if you look at the page prior it states specifically that its an unofficial report and should not be qouted or reference until approved by headquarters. To be clear while looking through the archives i did not find once where it states specifically it easier approved. And every time this report comes up (as it shows up a few times) it always has the first page stating it’s unofficial and shouldnt be qouted or reference until approved.

Also when reviewing the invoices from the company that built the QF ram there is no mention of the engine being upgraded. Nor from my research any ram upgraded with double the engine output. The issue i have is if the engine HP was doubled it would be assumed the transmission or any of the other drive train parts would also need to be upgraded to support the now double the power which i cannot find a single source of any of those parts being upgraded. I have not found a second source to back up the claim in this UK report stating it had a 800hp engine. As @Bruce_R1 pointed out earlier.

To be clear im not denying it could be correct im just stating im unable to find any claim or any secondary reference to this upgraded engine or anything that would be required with an engine upgrade that douvles the hp
