OR DO IT RIGHT LIKE THIS
I commend you, what a thoroughly considerate idea old chap - if you see a dear cyclist coming up the inside you could quickly switch flow to the stacks so as not to roll-coal on them and render them with a bad cough. 
Haven’t seen smoke like that since you could keep it lit but also press the exhauster on a Volvo to smoke a tailgater out.
so i’m told 
Only time I’ve ever got black smoke was out a 63 plate Scania G series rigid. Floored it away at a roundabout, saw in the mirror a big plume of black smoke emerge from under the body. Maybe the way to deal with those pesky cyclists is to angle the exhausts up at them then floor it away from the lights.
Screwed to the balls lad. No smoke no poke hi.

i still think my pish soloution would work better from the chris boardman post… 
A bit worrying to think that these people have the right to breed and vote! I once knew someone who drove a 124/420 but often played a CD of a roaring V8, nutter of the highest order.

any idea where you could buy one? they would sell well over here…

Used to work well on the old F10/12’s, keep it flat to the floor and press the ‘sorst’ brake with your left heel…used to blow out huge plumes of black ■■■■…it doesnt do the turbo any good though… 
My FH sounds throaty with its Eminox stack but the old rollin coal effect doesnt work on the new ones, the fuel is cut when the exhaust brake cuts in…spoil sports at Volvo put paid to that one…barstewards…

I used to drive a “Mighty Antar” and when we had a full squadron running fully loaded down a German autobahn it made for a pretty impressive spectacle, hence we used to get loads of German civvies waving at us from the motorway bridges as we passed. I nearly wet myself laughing the first time I saw the truck in front of me apply the exhaust brake while keeping the throttle pinned; the twin plumes of oily black smoke from the twin stacks was nearly as funny as the civvies who looked like extras from the black and white minstrel show as I passed them!
They weren’t waving then.
I thought the rollin-coal bollox was just too rich a mix, when we had adjustable mechanical pumps you would calibrate them my having some black smoke at full power under load. You don’t want too much as its a waste, but for some reason doesnt affect performance. as we can see with this 143
presumably with the modern common rails you would have to program the ecu to pump in silly amounts of fuel for the moronic rollin coal stunts.
Now if he’d had a bogie (double) drive with diff locks and cross locks he’d have made the Irish sea. My mate CF told me.

To be fair it’ll also need 12 cylinders not the wimp 8. 
Black smoke at full power is the result of too much fuel being injected into the engine, but why does that not adversely affect performance? obviously it doesnt as that is the standard set up in any high performance diesel motor where fuel economy is of no importance.
I sort of think on the lines that best performance would come from an optimal mix of fuel and oxygen but that clearly is not the case; The only theory I have been able to come up with is the excess fuel is improving compression, but does anyone know what the real answer is ?

I think it probably goes along the lines that firstly diesels generally work on the principle that their throttling is controlled by how much fuel you throw into them.The more fuel the more engine speed the more power.The problem then being that compression ignition can’t keep pace with the potential engine speeds in question.Hence dirty combustion which is outweighed by the advantage in engine speed so more power but also loads of incorrectly burnt fuel which of course doesn’t matter.
On that note it’s ironic that two strokes were put out of the frame on the grounds of emissions.Bearing in mind no DPF or electronic injection here which is how I remember a properly set up Detroit.

That sounds quite high revving and at a guess I would imagine a very narrow power band (with huge drop off out of that narrow band) It would be fun to drive for half a day, I would guess the novelty would wear off after the millionth gear change. - also, I’m sure they measured fuel economy in these two stroke diesels as gallons per mile 
(3 or 4 gallon per mile)
was the 'screaming ford a two stroke ?

Most of the early generations of diesels had a narrow torque band while ironically the non turbo 12v71 N put out more torque than the turbocharged ■■■■■■■ of the day.Both at similar engine speed of around 1,200-1,400 rpm.While 12 cylinders firing every revolution at 1,500 rpm just ‘sounds’ like a 6 cylinder running at 6,000 rpm firing half as many times per revolution.

you’re absolutely right CF, a two stroke is going to sound faster as its beating at twice the rate, and with 12 cyl to 6 that’s double the beats again.
A screaming ford would be fun to take into cenral london, probably quite safe too as folk would keep well out of your way.

You could have at least heard plenty of V16’s along these lines running through Feltham High Street under full load in the 1970’s.

I’d guess the Scania V8 karaoke act in the OP video would have lost the plot at anything much more than idle in that case.
