they did it LOL :D
-
Wahey, they did it :D
nice bit of kit that is.
-
Thing needs a bump start to 30mph before it will go by itself though.
Posted an article about this some time ago in another thread, good news they managed it though and getting a JCB to that sort of speed cant be mocked ;)
-
I neally crashed into a JCB once, due to tiredness.
-
The previous diesel land speed record is 236mph (380km/h), set in August 1973
1973 ? rofl
niot exactly that hard to beat then ?

Maybe that was a machine ahead of its time? But I doubt this one will be beaten for some time.
-
I reckon it could be, easily. I just dont think anyone else can be arsed to pour the time & money into it.
-
lol... fk that i wanna see an actual jcb do that speed :)
-
How big are the engines, torque etc. compared to the R10 ?

Did it again too...

Their site on the web ;)

Engine Spec Sheet (PDF). Its the JCB 444.

So in short, the stock version comes up a bit short, against the V12 TDI of the R10, tons of torque mind. But when you consider what the dieselmax was designed to do on the Bonneville salt flats and what the R10 has to do on the track, they didnt need/want a thumping V10. For one it only has a 9 litre fuel tank.

"The car has still got loads to give. I throttled back on the second run and we havent even used sixth gear yet, so the car can still go faster."
lol
-
Not bad 1500 Nm in one engine the R10 gives 1100 Nm
-
"The heart of the Audi R10 TDI is a completely new V12 TDI engine with a cubic capacity of 5.5 litres ? the maximum permitted at Le Mans. Audi ventures into previously unexplored diesel-engine terrain with power exceeding 650 hp and torque of more than 1100 Newton metres from the V12 power plant."
"The results of the JCB DIESELMAX engine development work are truly impressive and the headline figures speak for themselves: with each delivering peak power of 750hp and torque of 1500Nm, the engines are over five times the power of the production version and at 150hp/litre, they exceed even motorsports applications as the world?s highest specific power diesel car engines."

Scanias biggest monster currently gives well over twice that !
-
Yes, but Scanias are built for torque and have quite a few more litres
last time I looked out of curiosity on their site, iirc they have some 16 litre V8s!
Thats 2 litres per cylinder.. completely built for torque, not bhp & revs.
The dieselmax must be a good balance of bhp & torque because they cant rely on 18 or whatever gears to keep the engine in the powerband - it needs to rev higher happily.
-
Well, the good old masters of Diesel have done it again.
PSA are producing a 5.5l diesel with more torque (1300Nm), and more power (700bhp) than the Audi effort! And its going in a road car !!

No diesel is built to rev highly. That one in particular - 2 hours at full pelt. A tricked up lorry engine, that is built a lot heavier than a digger engine would sustain that kid of abuse longer.
Id say the speed was all high gearing - wonder if theyll do a VW and claim good mpg because they used an absurdly high top gear LOL
-
Well, Scania havent broken any world records for speed, so they dont get a say, even if they have diamond encrusted bores and run on 100% bull sperm.
-
Scania/Saab have broken loads of speed records over the years...
-
Shouldnt that read :
Scania/Saab/GM?
-
Not when the records were set (I think)
-
Was going to say!
Cant see GM being bothered to set records tbh
