how old is that thing? really awesome

@eroc2689 Its a 40 HP Case, probably manufactured around 1915.

it's incredible how little horsepower this massive things. wonder what the torque was though.  really wish we still used steam to this degree today. imagine how awesome it'd be with modern technology ^_^

[hartparr]

@thedefinitive Its pretty easy to figure out the torque. Torque = 5252 x HP / Speed. This is a 40HP Case engine (Although that rated HP is less than what it can actually produce) it ran at a top speed of 150 RPM which means Torque = 1400 Ft. Lbs. Quite a bit. Today, most power plants are steam driven but instead of piston engines like this, they are turbine engines which run at a much higher efficiency. Sometimes as high as 40% which is better than today's car engines.

Steam power baby!!

That's why they keep it clear behind the engine - everything does not need to be labeled "dangerous" that people are ignorant of.

@hartparr nah, those things were made around 1906

@hartparr thats why I love my steamers....they have been around sence the greeks build the frist out of wood and bronze...for a few hundred years now steam engines have had a 40 to 50% eff. and with all this techno crap we ant get over 25% with gas and diesel. Hell I have a 90 ford ranger that is running of a impact wrench at 80 psi liked to rear axle via 4" chunk-o-driveline I have 650 lbs of torque to work with and now no trany or engine wieght...yey for rednecking

@hartparr

Actuly not 150 rpms it is 250 rpms, some of the larger engines would run 230-240 and some portables were 100-200 it depends on the engine

[viperman5686]

@blibbax 5252 is a conversion factor. When James Watt decided upon a "horsepower" being 33,000 foot pounds per minute, he had to add that to make it come out equal. Otherwise Torque*RPM would be a measurement of power, just not in horsepower units. Just like how if you want to turn inches into centimeters, you divide by 2.54.

I wonder how they get it down from there, You'd think on that much of an incline, when you took it back down you'd expose the crownsheet. Unless they backed it down that is.

@hartparr Where did you get 5252 from?
