My friends Harley only takes 32 horsepower – that does not sound right?
I had my Harley dyno'd the other day, after some improvements (I'm up over 72 hp now) and my friend decided to maintain its Sportster on the dyno. The bike is a complete stock of 2001 with 3200 miles on it, and functions as it always has. When he was the test came out just 32 horsepower. I had thought that the CV in these activities was 45, but the speed shop owner insisted that although the 45 hp # is what you see a list of all times, in fact, the evidence provided Sportster in the 30's. Does this sound right or do not need to fetch it tested on a different dyno?
32 sounds pretty good. The 45 hp is probably the crank. Usually, lose some due to friction in the wheel. The good news however is that it does not matter anyway because he owns a Harley. It automatically makes people think his unit is 8 inches long that is. Aphrodesiac is the best man go!

Horsepower
$114.71 Horsepower (hp or HP or Hp) is the name of several nonSI units of power. It was originally defined to allow the output of steam engines to be measured and compared with the power output of draft horses. The horsepower was widely adopted to measure the output of piston engines, turbines, electric motors and other machinery. Different regions adopted different definitions of the unit. Most countries now use the SI unit watt for measurement of power. The definition of a horsepower unit is different in different applications; application outside of the context of a particular definition will be inaccurate. One mechanical horsepower of 550 footpounds per second is equivalent to 745.7 watts. A metric horsepower of 75 kgfm per second is equivalent to 735.499 watts. A boiler horsepower is used for rating steam boilers and is equivalent to 34.5 pounds of water evaporated per hour at 212 degrees Fahrenheit, or 9,809.5 watts. One horsepower for rating electric motors is equal to 746 watts. A Pferdestrke is a name for a group of similar power measurements used in Germany around the end of the 19th century, all of about one metric horsepower in size Author: Miller, Frederic P./ Vandome, Agnes F./ McBrewster, John Binding Type: Paperback Number of Pages: 164 Publication Date: 2009/11/03 Language: English Dimensions: 5.98 x 9.01 x 0.37 inches |
