I’m not bothered what the dyno reading is, it’s a great video which encompasses the sheer brute power of these majestic engines, an incredible design which truly revolutionised farming.
The guy on the steam tractor was like oh shit when he saw the belt bouncing up and down almost coming right off the DYNO. He increases the power of his machine as it’s making the chugging sound
The belt passes through resonant frequencies as the power and speed increase. When it starts to bounce like that you have to make a split second decision: Go faster to get off the resonance at the risk of sucking it in if it makes it worse, or go slower to get under it but be holding the engine back with the throttle. I like the show of force at the end, that even under load and at speed the safety valve still lifted.
I was stunned at how beautifully stable the engine was at those high rpm, but what is the point of putting her through the ordeal if no figures are made available?
Yes I know what you mean, I think it was just to put a show on as much as anything, I believe it’s the same guy that owns the engines and dyno, but I could be wrong.
It looks like the belt is not up to the task, It seems to stretch at high torque output. Bodicea had a close call with what looks like the same belt and it has alot more power
To be honest I think the problem was with the dyno rig itself not being able to handle to power, you could see it flexing. I believe they have mounted it onto something more substantial now to solved this issue.
That boiler would've been almost drained of water and is it oil fired or coal? What was the point of getting to such high horsepower, it's not a race car. How many tonnes can she drag? Looks like a 150 to 180hp type of traction. Should be able to drag about three loaded semi's on a slight grade.
@@110jaqw Hi Jake, I have a quick question, and I'm just making an observation, but are you sure she pulled 169.9 HP at her max speed and not 69.9? For the size of the Engine that seems more likely. At that Speed getting 169 Horsepower means she would have been making about 2,996 lb ft. of Torque, and I kinda find it unusual that her speed would drop by more than 100 RPMs, Her Horsepower would drop by 60, and her Torque would only increase by less than 100 ft lbs. If she was pulling 70 Horsepower @ 298 RPMs (which I assume is as fast as you'd ever want her to turn before she starts whipping and shaking herself to bits), she'd be making a little over 1250 lb ft, then as you crank the brake down a bit and give her more Steam it would make more sense for the increase in Torque to be more linear as her speed drops, and her horsepower would gradually increase to about 108 then start to taper off if they tightened the brake further. Another way the numbers would make better sense is if she was indeed making 170 horsepower at 298 (which would be extremely impressive, and hats off to the old girl and Fowler!), and 167 at 285 (if you hit 1 by mistake instead of 2) as the Horsepower would only drop by 3 and it would explain the marginal increase in torque to 3,084. Of course all of this depends on what her Bore, Stroke, and Boiler Pressure are. The new-build 150 Horsepower Case Steam Engine over here in the US, which is a bigger beast, wound up making 171 Horsepower at 180 RPM with around 5,250 lb ft. of Torque at about 175 PSI Boiler Pressure. As they cranked the brake down in her, as a rough estimate, each 10 RPM decrease from her governed speed of about 250 resulted in about a 150 lb ft increase in Torque give or take depending on how the governor responded and how the belt was reacting. They actually had some problems with the belt slipping and stretching because the Torque was so tremendous. The number I gave was the max they could get before the belt started squealing and jumping so violently there was fear it would either snap or jump off.

Holy fuck, those RPM. Props to the dudes standing nect to that much mass moving that way, nevermind the pulley.
It's hard to believe that engine is now 146 years old, and still runs great. No modern vehicles will be running at that age 😂
No doubt about it 👍🏼
❤❤❤❤
Kklkkks😢😢😮😂😅🎉

what about the hilux

Very high rpm! fowler engines were heavily built

A nice chuff 👍

Those belts should be able to take some torgue but they do tend to flex a lot but if they didn't they would snap
C'est une très belle vidéo ,j'aurai aimé voir une z7 à la place ou une b1.

Collin black coal
The operator will also be feeding water in when the glass shows it’s getting empty
The steam engine would of run faster if you add more heat sources like a blow torches and what about nitrous, nothing can go wrong right?
How many h.p.?
I’m not sure, they never put the ratings up on the board for this one, no idea why not
Would you say 140-150hp?
This engine a year before this video got a result of 169.9 HP @ 298 RPM 3,084 Foot of torque @ 185 RPM

14nhp for this engine
