The Meteor Crusader– The A15 Crusader with the 600 horsepower Rolls Royce Meteor

In that case, show me a picture other than a Ultra Blurry photo in a obviously fake AF report, of the Above Crusaders fitted with a meteor.

Sounds CRACKED.

Also yes, thank you for listing out the Features of the Merlin to me again.

That is all the stuff the Engine in the ACTUAL Crusader that had its test runs on April 6th of 1941, at the Aldershot proving grounds, on the Army standard speed course near Farnborough.

Where it made its famous over 50mph run.

The engines developed from that test, would become the True Meteor engines that would see use in the Cromwell and beyond.

The true Meteors had the Forged pistons replaced with Cast ones, Compression ratio’s lowered, had the cams regrouned and changed to provide the Vehicles with more low end torque, instead of high power numbers like the Aircraft engines, were retuned to use the standard 80 Octane leaded ground gasoline, instead of the 110 Octane AVGAS.(Partly why the compression ratio’s changed)

And were even then turned down to Produce 600hp to reduce the strain on the Drivetrains of Vehicles like the Cromwell.

That would be the Field Trial Reports held in the National Archives. - volume 8, page 468.

See, that’s from 1942, After the Meteor was already developed and starting to see Service, those testing reports are for Fuel Efficiency testing and such.

The Meteor started development in 1940, and the first proto meteor (aka this detuned Merlin im speaking of) was first fitted to a Crusader in 41. And like i said above, made its famous test runs on April 6th, where it ran off the end of the test track and smashed head first into a Telegraph pole. and hit speeds well in excess of 50mph.

Yeah with a meteor, not a merlin, noted you deleted you notion about it being a crusader 3 in 1941 etc. probably best to try and save face. here are the first two prototype engines

It was a PROTO Meteor…

The Proper Production Meteor was not the same as the Proto-Meteor/Merlin that was put in the first Crusader in 41.

It was a entirely different animal, ill say it AGAIN.

"The engines developed from that test, would become the True Meteor engines that would see use in the Cromwell and beyond.

The Merlinite (as i am now calling it) Was a Standard Merlin MK3 with the Supercharger, and reduction gear removed, along with the replacement of the Aircraft starter with a smaller Ground vehicle style one. And a new set of camshafts made by W. A. Robotham and his crew, to reverse the engines direction of rotation.

OTHER Than that, the engine fitted to that 1941 Crusader, was a merlin inernally, same pistons, same compression ratios, same fuel, ignition system, the works. So it STILL would have made leagues more horsepower than the later nerfed Meteors that would actually be produced from this test.

you can call it whatever made up name you want, but it wasn’t called a merlin, it’s clearly called meteor, they list its BHP and the dates and the tank number. now please other than what you’ve picked up from tik-tok or some other source can you show me any actual evidence with period docs (as i have) of them fitting a ‘merlin’ with 1000hp etc into a crusader. - all i’ve seen so far is your guesstimates and ‘feelings’ etc on here and reddit etc. this is not a hard challenge, please show any period documentation.

First of all, edfrancis001 is armoured archives, he really knows his stuff. He personally goes through archives to find information and is the source a lot of high calibre tank YouTubers (the ones worth at least hearing out) use for their own videos. Youre challenging one of the most knowledgeable gentlemen on his home turf. Hes also assisted myself and l2lan in some research into the A39 tortoise so I can personally vouch for his expertise.

Look at his channel

second of all

saying that to Ed of all people

the meteor uses a heightened compression ratio to compensate for the lack of forced induction from a supercharger

We are talking about a supercharger larger than most modern engines here, standard atmospheric pressure can not feed an engine of such magnitude very well at all in comparison. Its normal even nowadays for a NA version of an engine to make around half of what it will with a massive forced induction kit, my little MG will make 500HP done right when it only makes 160 without a turbocharger.

Well tbh really old engines like that seriously suck compared to modern ones.

Supercharger and stuff was also less advanced. So the Merlin could very well be pushing that power NA since it’s a much lower altitude than normal so moar oxygen than under flight conditions.

Iirc, the supercharged were there more to offset the high altitude power loss than purely for more power

Turbochargers are also really good at greatly increasing powerful efficiently that’s why they are more common than superchargers nowadays

that’s why its so damn big

It had it for power firstly iirc, it then had gears to work harder to compensate for thinner air from later marks

turbochargers weren’t quite as refined back then, the horsepower lost driving the supercharger was worth it in power increases from the compression boost

The gap wouldn’t be as big as you think it is then. Because sure, it doesn’t have a supercharger, but it’s also always at or around sea level.

And you said it yourself, turbo and supercharger weren’t as good so the 160 vs 500hp thing wouldnt really be happening with such an old engine

I used my cars engine because its old AF so hasn’t got the benefits of ultra-modern building technologies, its got its origins in the 1970s from a very bunkrupt British aerospace division and my car was the last production car to use one (alongside the lotus elise) so isn’t exactly modern other than being an aluminium block so isn’t very high tech at all.

this was a more extreme case, new rods and pistons as well as the forced induction, with just a turbo you’re looking at more like 250-300
I believe someone got 800hp out of a rover K series at some point too, I cant find the facebook link anymore though so cant remember if anything was stock.

Did it have an angry cat badge with red eyes on it?

But yeah I get it. I think it’s still possible for the tanks engine to be pushing that kind of power but also would not be surprised if it couldnt
