Notwithstanding all the obvious misunderstandingIs this an admission?
I meant misunderstandings on your part.An answer to the questions related to the parachute example and the bet regarding the 200 hp unit being able to pull a 38 tonner up to 60 mph v the less than 630 hp one being able to pull it up to 100 mph will do.
I understand basic physics as well as that schoolgirl I mentioned earlier. I bet you left school at 12, with boot propulsion behind you.

You seem to understand theoretical physics but you donât seem to be able to understand the real world princibles involved in âwinding upâ a reasonably powerful ( IE less than 630 hp ) fully freighted wagon to silly speeds.Trust me it works regardless of what the theorists tell you. 
Just as in the real world a 200 hp 38 tonner would be the most gutless heap of zb imaginable with more like around 50 mph being itâs flat out max not 60.

Ignore the logic; that difficult schooboy maths canât begin to explain anything, can it? In case of ignorance trust anecdote, instinct and superstition.
Repetition. Yawn.
had a few A reg erfs that would all do the clock âŚ
billybigrig:
Limiters came in about 88(E reg). Some of the last 2 series scannys and all 3s had emMy 85, 142 most definately did not
Limiters came in in 1993, I had new wagons in 87 and 89 & 90 no limiters on them

And neither did my 1986 ERF E14. 
In February 1992 Council Directive 62/6/EEC was issued which required certain categories of vehicle to be fitted with Road Speed Limiters. This was followed by Council Directive 92/24/EEC which set out, in the annex, the technical specifications for such limiters. These directives were then incorporated into UK legislation by amending Regulation 36 of the Road Vehicles (Construction & Use) Regulations 1986 by inserting sections 36A, 36B and 36C. (SI 3048/1993)

What about your Albion Reiver,single drive,Chris ? Cheers Dennis.
hallo, The fastest I have known here was the DAF 2600DKB with fuller box was it able to go as fast as 135kph
the F89/88 was with 16 speed box able to do 125kph well at 2500revs.I think original there were no faster here before '78. from then on came MB with itâs 18 speed box a transition box to the 16 speed box called
ZF S9 GP 111 + GV 90 build in the 1932 and the first 1928,and the transconti was fast too. In Britain they could have been faster because of the max weight of only 32 tonnes. Of course some had been changed other tires, diffs of buses and so on but that is not original.IT ALWAYS MUST BE ABLE to pull it max weight and climbing steep climbs with gradients of well over 10%.
in the '80 lots could do the speeds they had more gears faster diffs because they were more powered.
my dad ones has driven a volvo 165HP with 5speed and 2 speed axle and it clould do 95kph with about 38 tonnes in the best conditions, but on climbs it was in first and you had to stay in it till the top and always slow on climbs what do you want else with only 165HP.
It was a converted lorry to a artic so it had a fast ratio.
i think that I am straightforward telling this .
cheers Eric
I have been looking through the CM archives, to see if there was a standard factory specification which would give 100mph without over-revving the engine- so far without success! I found out that the 190.48 could have a 3.08 diff and a Fuller 13 speed, but this was a direct top version, which would give a top speed of only 76mph at 1900rpm. If Newmercmanâs lorry had the overdrive Fuller, with a ratio of 0.87:1, this would give 97mph on 315/80 tyres at 2100rpm, as the man said. I donât know whether the overdrive Fuller was a factory option.
I thought I could remember reading about vehicles which were geared, from the factory, for 60mph at about 1200rpm. I cannot find any evidence of that!
1988 ERF E14 400 with an eminox stack. The speedo goes up to 80. Itâs surprised a few wagons from the Emerald Isle when it comes home down the A1 on a Friday night before a show. All the time sounding great whilst it does it.
One from last year sticks in the mind. Was in the (limited) E10 heading to the Newark AEC Rally when an Irish wagon drew alongside me at Balderton (opposite where the Lightning used to be). He drew alongside, looked up and down the wagon gave me a thumbs up, the cab nodded and he was gone. By the time I slowed for the A46 he was out of sight. Probably booked on the midday ferry and he passed me at 9!

1988 ERF up to 80 ? Vehicles required to be fitted with a speed limiter are:
A vehicle first used from 1 January 1988 with:
a design gross weight of more than 12000kg and
a maximum speed capability exceeding 56 mph (90 km/h), if a speed limiter were not fitted
must be fitted with a speed limiter set at a maximum stabilised speed of 56 mph (90 km/h).
Hallo, lots disconnected the limiter in the early days as I a did but latter it came more difficult. And so some could be very fast with the higher power and higher ratios on the younger models with a disconnected limiter.
Cheers Eric,
Wheel tapper Iâm sure the date was 1st of March or May or something funny like that.
Just pull out one plug under the passenger seat and it doesnât matter what the limiter introduction date was!

I think that would have been safe enough to say that there wouldnât have been many,if any,euro wagons available on the euro market that would have been able to overtake the thing assuming it was being driven flat out on a long enough flat enough and clear enough piece of road.Which just proves the case that there ainât no substitute for cubic inches.

Copied details out of the testers manual today
Remember a owner driver who came into the VOLVO dealers I was at, he had a F12 registered Jan 88, He was gutted as I had to fit one on it, although that switch on the EARTH wire looked a bit suspect the next time it came in

Midland red coaches . .remember them
There is a fabled story that when the first part of the M1 opened Midland Red designed and built their own coaches for it, the story goes that they were capable of the ton.
Certainly back in the early 80s there was some quick coaches out there, Volvo B10Ms would knock on 90 and a Leyland Tiger TL11 wasnât that far behind. Late 70s Leyland Leopards were good for 80 or thereabouts, that is empty, on the flat with a tailwind⌠so much as sniff a hill and theyâd be down to half that.
A slightly different take on this subject ,how many of you have moved into the middle lane to let a lorry onto a motorway only for the driver to either accelerate away leaving you in the middle lane ,or getting up to 56 mph and you end up having to slow down to get back into the inside lane because you cant pass it ? Not the speed limiters fault i know but if they were set at 100 kms/h 62 mph it may make a difference.Many drivers dont want to drive at that speed ,some are restricted to much less ,i think it would stop bunchingbut it will never happen

Vehicles bunched-up, nose-to-tail, is a bad side-effect of speed limiters. Given that the legal speed limit is 60mph, or 96km/h, there is the possibility to allow different speed limiter settings, based on some parameter or other. How about this:
Operators can pay an increasing amount of road tax, according to the speed limiter setting of the vehicle. Those operations which are time-sensitive would pay extra to have their limiters set at 60mph, or even 100km/h. Operators who are more concerned about fuel use or driver abuse could pay a reduced rate of road tax and have the vehicle limited to 50mph, or some intermediate value. The higher-speed vehicles could be required by law to have auxiliary engine brakes fitted, while those with only a simple exhaust brake could be restricted to the lower tax brackets.
