"Six hunnert haws-pow-ah."

 

600 HP Snow Natural Gas Pumping engine at Coolspring June 2013.  Shown here is the start-up operation and shutdown of this most impressive engine. After several years of hard work, the job had progressed where the crew was able to perform a few test runs.  On this particular test ( the fourth start-up) a few mechanical adjustments had been made and on-line fuel valve settings performed.  My hats off to a truly incredible volunteer effort by the Coolspring Museum staff 

 This engine was manufactured by the Snow-Holly Works of Buffalo, New York, and is serial number G329.  It has two tandem 24 inch bore x 48 inch stroke cylinders that are double-acting.  Total displacement is 86,800 cubic inches or 1,423 liters.  The rated output of the engine is 600 hp at 100 RPM which yields a torque value of 31,500 ft-lbf.

  6. Now use 26" pistons in 2 banks. 4 pistons 8 compustion chambers at 1600 HP. Ours spun a 40,000 pound flywheel. Top speed is 125 rpm. Cooper Bessemers.

  7. Back in the 80s, the Crazy Horse Landfill outside Salinas, California, had an inline submarine (I think) engine having a centerline crankshaft and opposing pistons. It was used for low rpm, large displacement to extract landfill methane gas for fuel. When it was running, the landfill wiggled a bit as if an earthquake was happening. On-site workers were used to it, but periodic workers or visitors were confused by the sensation.
    But thanks for this video!

  8. NAPA don't carry parts anymore for those. Valve covers are on back order for 200 years unless you make them

  9. "" 600 hp at 100 RPM which yields a torque value of 31,500 ft-lbf.""
    ....so, about what nearly every 16yr old thinks he can get out of his Dodge Neon and spend every last cent trying.
