Horsepower my ass
 
A horse is pretty damn strong. If you tied an RX8 on one end of a rope and a few horses on the other, I bet it would only take like 10 horses to out pull the 8.

OK. Torque is what is important anyway.

Horsepower (HP) is the name of several units of measurement of power. The most common definitions equal between 735.5 and 750 watts.[1] Horsepower was originally defined to compare the output of steam engines with the power of draft horses. The unit was widely adopted to measure the output of piston engines, turbines, electric motors, and other machinery. The definition of the unit varied between geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on January 1, 2010, the use of horsepower in the EU is only permitted as supplementary unit.

The definition of the horsepower also has varied between different applications:

* The mechanical horsepower, also known as imperial horsepower, of exactly 550 foot-pounds per second is approximately equivalent to 745.7 watts.
* The metric horsepower of 75 kgf-m per second is approximately equivalent to 735.499 watts.
* The 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.
* Continental European electric motors used to have dual ratings, using conversion rate 0.735 kW for 1 HP
* The Pferdestärke PS (German translation of horsepower) 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.[2][3]
* The Royal Automobile Club (RAC) horsepower or British tax horsepower is an estimate based on several engine dimensions.


Help? haha

^I guess the man want to keep his nuts, who can blame him

The Reverend 03-02-2011 10:51 AM

what about asspower i think they have more torque but less top end speeed :cwm27:

Footman 03-02-2011 10:55 AM

How about girlpower? A bunch of girls showing off their titties can dominate a shit load of men into doing their bidding.. hahahaha

Finally a couple of people who realize the sarcasm and silliness of my post

Wtf, it doesn't take 232 horses to pull an 8? But that's totally how horsepower is meant to work!

mmmmm....titties!

Well 1 horsepower has never meant the total strength of one horse. It was based loosely on the amount of work a horse could do in a minute. after all the roundings that came to be moving 33,000 lbs 1 foot in 1 minute or 33,000lbs.feet / minute.

it would take much less than 10 horses to win a tug of war against most any car.

Galen Darkmoon 03-02-2011 08:11 PM

Not a fair comparison since you are talking hay burners to rice burners. :)

DocBeech 03-03-2011 01:19 AM

^Draft Horses^ at that. You ever seen a Clydesdale up close? Those guys stand something like 18 feet tall. Im pretty sure two or three of them could keep our car at bay.

" The strength of the Clydesdale was proved in 1893 when two stallions hauled a sledge laden with timber that weighed 128 tons."

I know this is pretty much a joke thread, but I'm procrastinating at work.. a tug of war and HP don't much relate to each other all that much. In a tug of war, if you can pull more than the normal force x friction constant worth in force vs the other guy, you'll win. ( that's not really that hard actually). If a car was on ice with wet slicks, I alone might be able to beat the cl65.

For HP, It would definitely take more than 10 horses to produce enough energy to get a car to 148mph against the wind and frictional forces, nevermind the fact that the acceleration of such a "horsepowered vehicle" would eventually reach almost a stop at a pretty low speed, no matter how the vehicle was geared. It's horsepower not horseforce.

horses could never get a car to 148 mph- they are physically limited to about 30 mph on average. some have been clocked up in the 40s and 50s.

and you're right about overcoming the friction/traction, Clarkson even said once the tires were spinning it was over. especially when the got him into the grass.
