Aec av1100t

[antarmike]

Does anyone have a reliable figure for the output power (or range of output power) for AEC's AV1100T, The turbo charged version of the 18ish Litre engine from their BIG dumptruck?

[rbrtcrowther]

Haven't got a clue.:coffee:

[Davie]

Is this of any use Mike? Looks like a bit of a beast.

I guess you've seen this http://aec.middx.net/units/engines1.htm?

[antarmike]

Cheers, that's the sort of info I wanted. A certain gentleman who writes books has it down as 235 BHP, but seeing as my Rolls Royce C6T Turbo is only 12.17 litres and gives 300 BHP, and is about the same vintage, and technology, to only be able to get 235 BHP from an 18 litre lump of the same age seems ridiculous. He may be right, but now I feel its worth further research.

 

AEC's own normally aspirated AV 760 of 12.4 litres gives up to 265 BHP!

Mike,

 

I take it that this about the Antar which was fitted with a AV1100? If so, Bart Vanderveen has it as 360bhp in the entry on this vehicle in his post-1945 military vehicle directory ( he is rarely wrong ).

 

Sounds like this certain gentleman does not do his research.

[antarmike]

I can't say whose work I am looking at but I read a figure and I thought, why would they take a vehicle that has a 260 BHP Meteorite engine already fitted and be pi55ing around trialling a New engine that only gave 235BHP when the whole idea was to improve the performance of the early vehicles, which had to be said was sluggish....I just wanted to know if my gut feeling that a Turbocharged 17.89 litre Diesel has to give out more than 235, when my 12.17 turbo lump gives 300B.H.P.

[antarmike]

I can find very little about AEC's biggest dump truck

The text with this image quotes output at 300 BHP.

Although the Super Mammoth for the African market is also supposed to have had the AV1100 engine. (but maybe only the normally aspirated version) I can find little about them either.

[N.O.S.]

W.Stevens-Stratten,in AEC Trucks in Camera, gives 340hp for the dumptruck. He seems to have access to a lot of spec sheets for AEC.

 

Nick Baldwin in Giant Dumptrucks quotes 340bhp (up to 410bhp SAE gross) from the 17.75 litre lump.

 

You may be interested to know Mike that this HDK4LA dumper was developed at AEC's Maudslay truck factory.

 

340 bhp would be about right as engines are typically downrated a little for dumptruck applications.

 

Phew it's hot in here by the wood fire, I must take my anorak off.

235 BHP is becoming more and more unlikely....Thanks N.O.S.

Mike,

 

You may be interested in a FVRDE report that is available from The National Archives at Kew.

Unfortunately thats a long drive for me!

Richard, I have tried most combinations of the above but failed to find the document.

Mike,

 

Use that link you have, and in the top left corner there is a seach box, type in this reference, WO 194 / 1206 this will bring the entry up, you cannot see the file online, but it will give you info in order to go and view it, or get a researcher to do it.

[antarmike]

I just typed Antar into the search box and it shows they hold quite a few documents.

Thanks Richard, I was using the 'search the catalogue' section and it wasn't having it.

I'll see what I can do when I am next down that way.

Does the exhaust really come out by the drivers left ear?

Post#8 shows that some had the exhaust re-routed!

Thought you might like this. It's not quite the AVT1100 but the turbo-charged industrial version, I think:

[antarmike]

The power curves seem to be foe the normally aspirated engine, theIllustrated engine is turbocharged and rated at 360 BHP. The power curves do not even get up to 280 BHP.

[philb]

You're quite right. It was the 360BHP for the industrial variant that surprised me. I would then expect the road and rail versions to be higher still.
