Lorries, how quick are they without the trailers?

Or take the fuse out!!!.



atpbx - you should try sitting in a loaded truck/trailer while it's knocked out of gear going downhill. Gets quite scary at 70mph+.

But thats not the lorry going fast is it?

It would go even faster if you drove it over the edge of a cliff but i dont see us counting that when it comes to quoting performance figures.
 
Just do what Dad has done...

Fit a switch which allows him to bypass the speed limiter :D

On some of the older wagons you can which of the ignition while driving and the engine keeps running. It also takes off the restrictor.
 
They've certainly got a bit of poke. I know the race trucks are different, but I don't think engine wise they're hugely tuned, and those things go some.
Race trucks are madly tuned. For a start they replace the standard diesels with v8 petrols (and what ever else tweaks they have,) move the engine from under the cab and place it behind it (and lower) and not to mention they have to carry a water tank to keep the brakes cool, else the discs would melt. All track trucks are limited to 100mph, too.
 
I don't know if you still can, but I've been informed by someone who drives sweepers, that you could get past the limited by repeatedly stamping on the accellerator (revving the **** off it) and the clutch to confuse the system in whichever gear you wanted to go faster in.

Probably a lie, but I'd like to see a lorry doing 80.

A sweeper driver? - somebody who drives all day at the kerbside doing 5 mph, I bet he dreams of speed! :p

He's talking crap tbh, or, putting it another way, I cannot think of any make / model of truck that has such a lame limiter!

Given most modern trucks are geared to deliver max torque at or near to 56MPH, its highly unlikely that many have the gearing to reach 80MPH, never mind a driver daft enough to try..... ;)


Power output is anything from 280 - 680 BHP with insane torque levels - its the torque rather than sheer BHP that gives a truck its ability to pull weight.

My current DAF 105XF is a 44ton 6 axle artic, it has 410BHP 12.9 Litre in-line 6 engine with about 2,000 nm torque @ roughly 1500 rpm. :cool:

if only all limites were created equal :(

would be great if there could be a system that gave a truck X amount of time to overtake, but if it didnt manage it - it's limiter dropped to say 50mph for a minute or so.

Not really.

I can tell you've never driven a truck in your life mate.
 
yeah.. you're right, i've never driven an iveco stralis, no-one in my family has an HGV licence and i've defeintly never been to valencia in an artic.
 
it was in response to you saying that you can tell i've never driven a truck in my life.

my post wasn't a dig at you, or most HGV drivers on the road - just the ones who like to block two lanes for X amount of miles, forcing middle lane drivers into the fast lane. which never goes well because they think that 65mph is fast.

But if your suggestion was followed through if they failed to overtake everything behind it would have to move into the fast lane due to the lorry suddenly slowing down and having to go back into the outside lane.
 
ok, lets mix laser quest and driving - if the overtaking lorry gets to a point where the driver can get a shot on the driver, he reduces the speed of the lorry being overtaken by 5mph for 30seconds, allowing the other lorry to pass? :D
 
Like Phate says, it wouldn't be that workable an idea, I was'nt having a go at you either mate just observing from what you wrote, that you have no experience of what it is to be in a truck.

The trouble with overtaking trucks is , in the main, the guy being overtaken would rather not lift off the gas a touch to let the other truck past, lack of thought on the part of the driver being overtaken and often poor forward thinking of the driver attempting to overtake (at the bottom of a steep incline for example, you see it all the time!)

Laser quest? I'd rather have a handgun for some of them.....:D
 
hehe, that might be counter productive though - we'd end up with stationary trucks on the motorways then.

When was the restriction brought in, I don't know how long ago it was or how old you are - did you drive HGVs before the limiter was brought in, and if you did, what was it like before that?
