Weight is 882Lbs
Height is 164.04 feet
Time is 24 seconds
One horsepower is 33,000 ft/lb in a minute
One minute is 60 seconds. 60/24 = 2.5
So, 882lbs x 164.04 feet x 2.5 = 361708.2
All divided by 33000 = 10.960 hp required
[so much for "modern" mumbo jumbo metric rubbish.....]
[plus an allowance for frictional losses and accellerating the load]
