I've been watching this new to me TV show called 'Mighty Car Mods'  .  It's a couple of clownish fellows down under who like turbo's & drifting . They do cut & paste car mods & burn up tires.
Anyhow, they use kilowatts in place of HP. I'm hoping that is not coming to the states any time soon. Seem's far fetched. But Good old Briggs & Stratton now uses cc's instead of HP, so anythings possible I guess??

I wonder how many kilowatts a top fuel dragster has? :)

It's just another form of measurement is all...

But briggs doesn't use CC's to measure power, CC's is used to measure engine displacement. Similar to Liters, and Cubic Inches.

example our engine is 2,555cc or (Rounded up to) 2.6L (Most engine displacement in liters is rounded UP to the nearest 100cc)

KiloWatt is an actual measurement of power where Horsepower is essentially a semi-made up one (Waits for s*** storm) that is devoloped through an equation based on FtlbTQ multiplied by RPM divided by 5252

1 HP = 0.7355KW

"But briggs doesn't use CC's to measure power,"  Yes I understand that. I'm just saying that after nearly a hundred years of advertising their engines by HP, they now only use cc's.

Kilowatts is a measurement already used in the States, just not for the overall North American automotive field.

Many countries use KW over hp for power measurement. We are just among the weird ones that don't and also don't use the metric system.

Because cc's are getting bigger than HP, or Kw.

When I was in grade school in the early sixties we were told that the U.S.A. would be all metric within 10 years.
I think it's just more communist intrusion. :o :D :lol:

I heard we would be all metric in 10 years when i was in grade school in the 80's too.  My education is electrical engineering so it's all second nature to me to convert, but still struggle sometimes changing units with having to "calculate in my head" rather than "just knowing" when I hear a figure quoted.  My hybrid Altima has a watt meter in the dash where the tach goes.

746 watts = 1 HP  BTW, so I just calculate in my head  with 0.75KW = 1 hp

I got a small taste of that when choosing / installing a 20HP rotary phase converter in my shop. Now I'm scratching my head over a variable speed DC drive to run a 7.5 HP DC spindle motor on my screw machine.

The reason for the Briggs and Stratton issue I belive is because they got sued for over rating hp or rating it differently among certain engines.
