Is a 10 hp gain noticeable?
10 hp would not be noticeable in either car.
The cars are so heavy 10hp is barely noticeable.
If you had a motorcycle and add 10hp it would be noticeable.
With the E60 or any other mid size car you have to add 50hp or more to really notice it..
Does torque increase with speed?
The Reason that Torque and Speed are said to be inversely proportional is the ability to generate torque diminishes with increase speed. The reason for this is because the BackEMF opposes the supply that is attempting to force current into the stator, that will generate EM-Torque.
Is 400 ft lbs of torque a lot?
Having 400 pounds of torque down low means you have more horsepower down low. Having 400 pounds of torque up high means you have even more horsepower then you had down low.
At what RPM is an engine most efficient?
Generally speaking, the faster the engine speed, the more fuel the engine is using. Between 1,300 and 1,500 RPM is the most fuel-efficient engine speed, or what some would call the “sweet spot.”
Why do lower gears have more torque?
Within the capability limits of the engine, shifting into a lower gear allows the engine to turn faster, allowing it to produce more power which the transmission converts into greater output torque for a given wheel speed.
How much horsepower is enough?
Usually somewhere around 250 is more than enough for normal people or beginners so they don’t kill themselves. For seasoned enthusiasts 400 or 500 may be fine. If you have no sense of self preservation and just want to almost die a whole lotta times. 1000 HP is for you.
Does more horsepower mean more gas?
A high level of horsepower in automobiles is useful in applications such as high-speed racing. But under typical driving conditions for family automobiles, using high horsepower uses more fuel.
Is 200 hp good?
Under 200 Horsepower Horsepower is undeniably attractive, and these days even the most basic vehicles have the horsepower necessary to pass most vehicles on the highway. As such, horsepower under 200 can be quite good. This level is sufficient for drivers who don’t actively seek road thrills.
Is horsepower a speed?
The power produced by an engine is called its horsepower. In physics, power is defined as the rate at which something does work. For cars, horsepower translates into speed. So if you want to go faster, and get up to speed quicker, you need more horsepower.
Why is horsepower called horsepower?
When the steam engine began to do the work of horses in the mines during the early 1800s, the mine owners began to ask how many horses an engine would replace. James Watt, who invented steam engines, figured out a mathematical way to equate horses to engine power. Thus the term horsepower was invented.
Is 500 hp fast?
It’s not even for most. 500 horsepower crosses a threshold. It’s at that level of power that you begin to feel real weight on your chest when you accelerate — like the steering wheel is trying to break free from your hands. The world around you starts to move faster than you can reasonably react to.
Does more torque mean faster acceleration?
Basically, the faster the crankshaft spins with the same amount of force, the more power an engine will make. A car with more hp than torque will always be quicker since this gives a car acceleration and speed. … Higher torque doesn’t mean one vehicle will necessarily be faster than another, though.
Does more power mean more speed?
Power really only applies to speed. A car with higher power can achieve higher speeds and maintain them easier, since the engine can give more work (torque) at a faster rate. If you want to compare how quickly two cars can accelerate, most people use power/weight ratios.
Is 700 hp a lot?
In a straight line, assuming it is built properly, a 700 horsepower car with traction control is a breeze. When you are not in a straight line and include the dynamics of weight transfer, well you can get into big trouble fast.
Why diesel engines have more torque?
The higher turbo boost pressure, high compression ratio, and greater heat content of the fuel all add to the generation of cylinder pressure that is substantially higher than in gasoline engines too, but it is this continued injection of fuel that really makes the big torque numbers for diesels.
Is it better to have more torque or horsepower?
Horsepower is how rapidly the vehicle can perform that work. … Of course, horsepower is tied to torque mathematically. Horsepower equals torque multiplied by rpm, divided by a constant. Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.
How much fuel is in a horsepower?
On average, an in-tune four-stroke gasoline engine will burn about 0.50 pounds of fuel per hour for each unit of horsepower. Likewise, a well-maintained diesel engine burns about 0.4 pounds of fuel per hour for each unit of horsepower it produces.
How many ft lbs is 1 HP?
550 ft lbf1 Horsepower (Imperial Mechanical): 550 ft lbf/s. Approximately 745.69987158227022 Watts (SI).
