[Roadsters] Question on conversion

[Keith0alan at aol.com]

It could be how they were required to measure engine power for the  
different countries. At that time the US allowed HP to be measured with no  engine 
accessories such as alternator or water pump. Japan may have allowed "at  
the rings" power, Power calculated from engine cylinder pressure totally  
eliminating all engine friction, cam and distributor load, etc. . Currently  
everyone measures with all engine accessories, air cleaner, exhaust system, how 
 the engine is actually equipped in the car.

The link  the shows a 1962 Fairlady race car shows this as HP rating:

Engine Max.  power

59kW (80PS)/5,600rpm
My Single Carb, which this doesn't show  the carb setup for the 1962, but 
it 
is rated at 77 HP, when they added the  dual carbs it became 85 HP.  Don't  
think back then there was  anything changing the HP rating between Japan 
and 
US,  so wondering  why it is showing 80 HP when converting 77 HP to KW it 
is 
56.63 or   57 KW if you round up?

Any thoughts or insights?
