Twisting force (torque) is measured in ...?
Nm.
Is torque or HP helping to accelerate faster?
It is like asking a Rs.2000/- note or a bundle of 100 pieces of Rs.20/- each notes. horse power is like a Rs.2000/- note. Speed is like Rs.100/- note torque is like Rs.20/- notes. They are related. power is converted into torque by low gears and to speed with high gears. To start and to climb you need great torque at low speed and on a level road you need higher speed with low torque. Money has purchasing power and Horse Power has physical power.
Which is the best unit to measure how powerful an engine is; Torque or Horsepower?
The power of the engine is measured by Horsepower. To measure the HP, torque is vital one.BHP means the maximum horsepower produced by an engine before the power loss by the drive train. When an engine runs at maximum RPM the BHP also increases. Torque is the twisting force of an engine. Max torque produced at lower rpm. The diesel engine has more torque and petrol engine has high power.To know more - Venkatesh Ragupathi's answer to In reference to engines, how are BHP and RPM related?Venkatesh Ragupathi's answer to Which car engine has been the most powerful up to now?Custom made the real most powerful car engine in the world is Devel Sixteen V16 Hypercar which has 5000-hp, Quad-Turbo, 12.3-Liter V16. this is craziest power ever which has the redline of 8000 - hp.Devel Sixteen V16 HypercarThank you for A2A!Cheers!
How were HP and torque measured in vehicles?
If you connect a big flywheel to an engine and put it at maximum throttle while recording the angular speed (RPM) of the engine over time you obtain a graph.If you take the time derivative of that graph (the slope) you obtain the angular acceleration of the flywheel at every angular speed.The angular acceleration of the flywheel is proportional to the torque of the engine at that angular speed. If you know the moment of inertia of the flywheel you can get absolute values of torque.If you multiply your toque values by the RPM at which it was calculated you obtain the power at that RPM.Torque ( Newton*meter or Joule ) is the amount of energy the engine transfer to the “load” for each radian of rotation. (at that rpm at full throttle)Power ( Joule / second or Watt) is the amount of energy the engine transfer to the “load” in 1 second. (at that rpm at full throttle)You can even calculate power and torque of your car if you use your car as the flywheel and you know the weight of your car. It will not be very accurate because of air drag, friction and rolling resistance of the tires but can still give you an idea. You just need to put your car, for example, in second gear and accelerate from idle to red-line at full throttle while recording the tachometer and the rpm gauge. The obtained rmp/speed graph is the same as above but you’ll need mass of the car instead of the moment of inertia to calculate the torque.
Relation between HORSEPOWER and TORQUE?
Here is one way to do it: Mechanical work is defined as a force acting through a distance. In the foot, pound, second system measurement system, work is measured in foot-pounds. Power is work done per period of time. That makes power foot-pounds per second. One horsepower (Hp) is defined as 550 foot-pounds per second or 33,000 foot-pounds per minute. Therefore: Hp = {[Force(lbs) X Distance(ft)] / Time(min} / 33,000 For something that is rotating, the distance / time part is (circumference X revolutions / minute). Circumference is 2Pi X radius. Torque is force X radius, so force = torque / radius. Rather than force X distance / time you have: (torque / radius) X 2Pi X radius X RPM Therefore: Hp = Torque(lbs-ft) X RPM X 2Pi / 33,000 Instead of multiplying by 2Pi and dividing by 33,000, divide by 33,000/ 2Pi = 5252. You could also start with one watt = one newton-meter per second.
Hp or torque? Drag race or drift?
Ok i just wanna know what really matters the most hp or torque on a racing car for drag racing and dtifting ? I know weight matter alot too but other then that what should i look for in a car for drag race
BHP vs WHP vs HP vs Torque?
Wheel HP is what is delivered to the road. BHP - Brake horsepower is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump, etc. and is the figure auto companies like to advertize. My 1953 MG TD has a BHP rating of 54.4 hp, and a delivered (wheel) rating of 10.97 hp.
Why aren't all cars rated at same RPMs when measuring HP?
Why are some cars rated at really low revolutions per minute while others are much higher. Example, -2004 SVT Lightning (v8 5.4L supercharged) is rated at 380 HP @ 4,750 rpm and 450 ft-lbs @ 3,250 rpm. -2009 Nissan 370Z (V6 3.7Litter) is rated at 332 hp @ 7000 rpm and 270 @ 5200 rpm I mean, the Ford doesn't even rev up to 7000 rpm from factory, what if I measured it's power at those RPMs, wouldn't i get like 500 HP? Why aren't they measured all the same to be able to compare fairly?
Does torque show up in quarter mile times or just horsepower?
Your missing a third ingredient which is traction. I you're setting up your car for drag race only use, you want engine rpm to roll just past maximum horsepower in high gear at the end of the quarter mile. You'll need a final drive ratio of 4.56 to achieve maximum quarter mile times with a full stock body Camaro and a 305 motor. *Miles per hour doesn't mean squat in drag racing. It's who gets there first. In plain English you want the car to reach maximum speed as fast as possible. If you have a stick car you'll want a close ratio transmission. An automatic will need a high stall speed converter to get the car moving at top speed as fast as possible. Tires and a trick suspension nails torque and horsepower to the track. A prime example is the new *stock 650 horsepower supercharged Corvette. With stock tires it'll roll through the lights @ close to 135 mph. Elapesed time is only high 11's or low 12's. Things don't add up! Drag tires, stick transmission with a better set of gears, better exhaust system and a lower final drive ratio would improve the times well into the 9's.
