Limiters came in about 88(E reg). Some of the last 2 series scannys and all 3s had emF reg 3 series didnât have them fitted.
Maybe not when they were new, but they would have been fitted to F reg lorries when the law came in, and to some E reg as well. Think it was from May 88 onwards 60mph at first for a year or so then down to 56mph.

Yes they were retro fitted to these vehicles, but like the thead name says, before speed limiters. F and G registered Scanias didnt come with them fitted and they were flying machines at the time. Even when they were retro fitted it wasnt much of a challenge to overcome them, and at first nobody seemed that bothered 
The hand throttle would override the limiter on some 113/143s. (Strangely you could get a good earth through the hand throttle cable aswell if you should need one 
)

Some of the late '80s motors were geared for around 100mph as standard: the MAN 502 and possibly the Iveco '48, IIRC. When did limiters become compulsory?MANs were always quite fast, the oneâs I had all had a 13spd Fuller in and would all go well off the clock, had one of those pink ones for a couple of months, ex Independant Express a 22-331 and did a 750kms round trip from Belvedere to Haydock every night, quickest I ever did was 3hrs 20mins, longest was still well under 4hrs, so I was keeping her lit every night. Used to put between 250 and 300 litres in the tank when I finished every morning, so it wasnât terrible on fuel considering the speeds it was doing.
My 190-48 TurboStar was good for 100mph, of course I worked this out using a slide rule calculation using the gearing and rpm numbers, I would never do that speed on a public road like the A2 with my dad following me in a car to confirm the speed as the lorry speedo only went up to 80mph, that would be irresponsible
Had a 1735 Merc that was fast enough to get the mirrors to fold in with a loud bang at about 200rpms after the needle maxxed out on the tacho, it had more to go too, Iâd say it wouldâve given the big FIAT a run for its money
My Dad had a four wheeler V8 D series with the range change box, now that was a flying machine, sounded like a two stroke when it was flat out, I suspect some tampering with the governers had been done. He had an AEC Marshall that would leave a Midland Red bus for dead too, so that was a fast lorry
Once had a 1635 Merc with twin eminox etc and when I nused to go to the ferryport to ship out, i used to go down âon the quietâ and my wife chased me down the motorway and had to do 100mph+ to get passed me

Drove a merc 1632 reg odo664r for buitelaar at boston geared at 103 mph, you selected top gear at 80 mph ish, That when i was full of â â â â â no brains, still got no brains but wiser i think but open for debate â â

No chance, they came past you like you were standing still.
I have seen some fast motors in my time and been in a few that would do 75 + but I have yet to see one that would do over 100 mph. I dare bet that in those days of 32 ton if you pushed a motor to those speeds the tyres would not be able to cope with the friction and there would be rubber all over the road. I may be wrong but maybe someones imagination is running away with them.
I donât know about a hundred mph but those 26 and 32 Mercs certainly got a move on. Big 1200x20 tyres on split rims does make you think though doesnât it.

True my F reg 450 had the limiter actuater on the chassis and a cable that kept mysteriously breaking running up to the throttle

Trust me those types of speeds were even more common then in the states than they are now.But the combination of wind resistance and accelerating that amount of weight up to those types of speeds wasnât possible with the types of power outputs available in most euro wagon at that time.Maybe with the exception of the V8 Fiat.
I still do 75 in my tm just to blow the cobwebs out !!!

I was actually agreeing with you concerning the âoverâ â100 mphâ at 32 t gross statement.Just not that it was tyres that were the issue more the power outputs available at the time in euroland.
I read somewhere- possibly in Commercial Motor, when they had proper technical articles in it- that it used to take 200bhp to make a 38 tonner do 60mph, of which half was wind resistance and the other half rolling resistance. I canât remember if that was with a flat or box trailer, or if any air management devices were fitted. Either way, it means that it would take 630bhp to make the same vehicle do 100mph. This makes the reasonably sound assumption that rolling resistance is constant, and that wind resistance is proportional to the cube of speed. The solo tractor unit, assuming an unladen weight of 8 tons, that rolling resistance is proportional to weight and the wind drag is unchanged from that with the trailer on, would require 500bhp to do 100mph. A slight downhill gradient will obviously be of benefit to lower-powered vehicles, in their quest to reach the ton! Of course, the governor on the engine must allow enough revs and the gear ratio must be âtallâ enough. Newmercman- can you remember what gear ratio your Turbostar had?

Although I was never a fan of âlow flyingâ we did have one Atki,OJM 480L which we added a two speed change to the Eaton axle when the motor came new but at the time we should have fitted a lower geared crown wheel and pinion.The result,prior to us fitting a lower ratio diff,was a flying machine that you struggled to get into high tenth! I was clocked,tractor only,at over 80 MPH when I finally changed up into top,then my âbottleâ went as the Kendal By-pass was no place to find out what the top speed might have been.Once we changed the crown wheel we brought the speed down to a sensible level,but this particular Atky was still an impressive performer âspeed wiseâ and it could pull as well,great motor!! Cheers Dennis.

Oh yes we did,on more than one occaision when I was a mate on one of the Brady Octopus and trailer,although I will concede that Standerwick did usually pass us on the M1/M6.It was always claimed that when the sister Octopus pulled a trailer in itâs early days it was known to have passed Midland Red coaches on the M1,I know who the driver would have been ( RIP) and his nick name is a word that was universally used years ago to describe someone with a dark complexion but is now taboo!! Cheers Bewick.
i drove an erf e series for a small company in clitheroe, gaffer bought a damaged f reg (ex edworthys of bow) with a 400 â â â â â â â in it could top 80 no problem, used to run home from plymouth on a saturday morning i could always tell when i got to m5/m6 split cos the speed of trucks used to climb by about 10 mph, we were all going home with the same idea, lets get a move on !!!
BRS Rental S/A 400 with 280RR - there didnât seem to be an end to the speed it would do,bottled out at 80 on Burton by Pass one night,Ford Transcontinental HA4424 (let it lug) with a drag was good for 80 plus but trailer used to start weaving a bit,ERF E14 on a âDâ plate with 325 â â â â â â â was another fast motor,Marathon with TL12 over 70mph on the speedo - and plenty of other Marathons used to pass me AEC MK3s and MK5s were good for 70 plus in silent seventh as well,as coppers reminded me on the old A48 around Cowbridge one day.
Heard about all sorts of tremendous speeds,ususally in cafes and pubs,the later int pub the faster the wagon.
Some Tilt cab AEC Mercurys and Marshalls would trap on,I had a Mercury on market work which do 60+ on the clock and Trowbridge Transport Sheffield Mercurys would still pass me on M1 homeward bound.
Well, somewhere along the line I really missed out. I started driving in 1968, with all manor of wagons,too many to mentioned here, but, including owning both an F89 and Transcon, neither of which, if memory serves, did more than 65 mphâŚI conclude, that every vehicle I ever drove/owned, was either fitted with standard diff ratioâs, or the wagons mentioned on here were fitted with high, in some cases, very high rear axle/ gearbox ratios. What I donât recall was, that with either the Transcon or 89 freighted, that much went passed meâŚ
I canât begin to imagine what driving a lorry (older-pre-limiter days) lorry, in excess of 70-80-90 and even a 100mph must be like, pretty frightening I would imagine,especially trying to stop it, the brakes on the Transcon scared the crap out of me at a âsedateâ 60âŚ
