Can anyone tell me why all new power equipment dosent list engine horse power anymore?, it list engine cc's.? So how would I know a 5hp engine from a 6hp one? Is this something to do with that HP lawsuit I got for engines awhile ago? Now everything says 208cc 420cc 614cc ect. What a joke. Thanks J

It's because they all got sued for OVERrateing their motors hp. Now they don't want to list HP, just CC's and you get to guess the HP!

So if we can't lie about the horsepower, we won't give any at all?

It's a strange world.

Ya thats another joke, I went to get a battery for my Dakota the other week, guy say what motor you have, I said a v6, he says no is it 3.3 or 3.6 or maybe its 3.9 I dont even remember. Years ago If I went in for a thermostat or something for a chevy you told the guy a chevy 350, or 400. What the $ell is this liter crap? Now, I have no idea what ci a v6 Dakota motor is, nor do I give a rats tail..lol J

It likely has alot to do with the lawsuit. Last I looked they were all rated by torque or something. Marketing gimmick I guess.

I don't understand what people hate liter ratings for.It is not a good way to measure power but neither is cu in. It is the same thing as cu in only in metric. 1 cu in equals 16.39 cc. So a 350 is 5736 cc or 5.7 liter. Not all that hard.

That sounds good, "I need a water pump for a 5736cc smallblock chevy"? Just plain stupid, they have been saying since the 50s were gonna convert to the metric system, ya and Im gonna take my Farmall H to the moon tommarow, I dont care how "hard it is or isent", its just stupid.

Hey !! doing some research I can now make this topic more Kornfusing -- LOL
----------------------------------------------------
205 cc = 8 to 9 Gross Torque = 5.5 to 6 hp

250 cc = 11 to 11.5 Gross Torque = 7 to 8 hp

305 cc = 13.5 to 14.5 Gross Torque = 9 to 10 hp

342 cc = 15.5 to 16.5 Gross Torque = 11 to 12 hp

http://www4.briggsandstratton.com/mi...P3845_1106.pdf

Briggs and Stratton model numbers convert to cubic inches

1 cubic centimeters = 0.061 cubic inches. That means whenever you want to convert a cc quantity into ci just multiply it by 0.061.

Just talking to a buddy about the same thing this afternoon.....the cc rating vs the HP rating is one of the most STUPID things I've ever seen. maybe if all of us would take the time to write and tell the MFG's how STUPID they are for doing it and THEN SUE them because the xxx cc engine didn't pull our 5 HP application because we needed a xxy cc engine maybe we could accomplish something.........Problem is I just don't see it happening.........

Some B & S engines are now rated in gross torque numbers.

That is because Americans arnn't fluent in Euroweeniespeak.

I agree that the displacement of an engine has nothing to do with the horsepower it puts out but if the HP ratings of engines are being exaggerated or lied about by the manufacturers, they mean even less than the displacement dontcha think?
I don't think you can really accurately correlate an engine size to a horsepower. How many different forms has the venerable 350cu/in chevy engine taken over the years? Each one putting out a different amount of HP.

Exactly why the Nebraska Tractor Test was established 90 years ago. And yes it's still the Law here. Every tractor over 50 advertised horsepower sold in the state of Nebraska must be tested at the University Lab. I can figure the gross horsepower of any engine given the compression ratio and displacement but it's all meaningless. Actual horsepower to the ground or driven equipment it what matters.
