And in 1987 the Chieftain was being phased out of service… what tanks would they keep in service the longest? the ones with the most reliable and highest powered engines…
Your own logic is flawed.
The ONLY Chieftains to get the 860hp L60s were the Recovery Vehicles, because again, THEY WERE LIGHTER, AND WERE ABLE TO USE THE EXTRA HP. Any extra HP in the actual MBTs, caused excessive strain on the Transmission.
These thing called governors and such exist, the Chieftain already used them in the early L60s because the engine was CAPABLE of outputting more power, but weren’t reliable at those Higher HP numbers, hence why the early models were limited to 660hp.
Yeah sure you could uncork the Late L60s in a Mk10/11, and get that full 800+ Hp, but its gonna grenade the gearbox and throw the tracks.
They limited them for a reason.
The armour is the same, the side turret armour of the Shir 2 is actually better than the Challengers as it has more composite in place of the TOGS
You clearly dont know how to read sources, one specifically talks about the Mk.5, so why even send it
The other never specifies which variant, so it’s meaningless. The weight of this source (55 tonnes) matches with the Mk.5, not the MK.10, so it is likely talking about the Mk.5
It just says “L60” which is vague and meaningless in this context
Provide some for the Mk.10 and I will care, otherwise those do not matter

actually you were right, the Hull composites on the Shir are SLIGHTLY weaker, the Shir can’t stop M735, the Chally can.
This source is specifically talking about the Chieftain Mk 5. No matter when the book was written, why would they include the specifications of later marks of the Chieftains?
It would be like finding a source for the Panthers that merely describes the Panther D, and using that to claim all Panthers had horribly slow turret traverses.
If you have a primary source that claims the later, uprated L60 were never used in Chieftains, only in ARVs, post that.

Mk5 is actually 720 iirc lol
False mk10-11
They have the mk13 (iirc) L60 making 840 bhp
I specifically said it’s a bad source, I just used it as I couldn’t be othered explaining
I added the Leyland society source in addition as well
I guess it may depend on the variant of MK.5
I literally spend hours and hours looking into the engine about a year ago there should be NO debate about it at this point.
Mate, EVERYWHERE on the internet says the L60 when mounted in the Chieftain topped out at 750hp.
Not just Wikipedia, but actual British army forums say as such.
No it had to do with cracking of the cylinder bore
So you agree that the MK.10 should be 850hp? just to be clear
Feel free to provide them but the British Army forums, assuming its just random people talking about, arent a primary source
the only “source” Ive seen that backs up the 840hp claim, is one Leyland Magazine that isn’t even wrote by leyland or anything.
its not a Primary source, there are PLENTY of PRIMARY sources that call out the 750hp rating.
(Even more that call out the 760HP rating of the Mk11)
840 as per my sources
As per Mr. Hewes yk the guy who owns and is licensed to fix the damned things.
