Higher torque ratings are more important than high horsepower ratings if you pull a trailer, haul heavy loads or drive on roads with long, steep grades. If you like to see how fast you can get from stoplight to stoplight — or if you do a lot of quick accelerating — horsepower is more important. Torque is a measurement of an engine’s power, closely related to horsepower. More torque indicates a more powerful vehicle and is also a good indication of its acceleration. Horsepower and torque are two common measurements seen everywhere in engineering -- especially automotive. But for the average person, what's the difference?

It depends on the car but generally the two work hand in hand. A modest, economy car might have horsepower and torque numbers in the 200s range. A performance car might have numbers in the 400s range. Torque and horsepower are the yin and yang of your engine. I have the more detailed explanation of this elsewhere in this Tech Tips section but the short, funny version of what the difference between horsepower and torque is; When a race car hits the wall during a race, "horsepower" is how fast the car hit the wall. "Torque" is how far that car moved the wall. Think of it like this; You can stop a 10 year old kid going 10 MPH on a bicycle by grabbing his handlebars and biting your feet into the ground, but you can NOT stop a 10 year old kid if he ... Horsepower is calculated using the amount of torque at a given RPM. HP = Torque(@RPM) X RPM/5252 That is why HP and Torque curves always cross at 5252 RPM. In my opinion, for street driving, the HP is a useless number. A torque curve is a better indication of how a car will perform over a range of RPM's.-----Bill Krause '79 911SC Euro Horsepower is a measure of torque over time, the rate of the work done to move a car (1hp=746 watts of energy).Basically, this determines how fast a vehicle can travel. Torque is simply a measure of the twisting force the engine creates as it spins, the engine's ability to turn the driveshaft and tires, making the car actually m APR stage 2 93oct high torque vs. Unitronic stage 2 apr claims 387hp and 409 ft/lbs unitronic claims 397hp and 368 ft/lbs tell me real world, which is worth it? butt dyno's are fine. thing i like about Uni is that you can do everything at home with the uni-connect cable. I've also read that Uni's tune is more smoother power delivery. Units of measurement BHP, lb/ft, nm, PS, KW. Traditionally brake horse power or BHP is the unit of measurement we use in this country for power, and lb/ft the one we use for torque. But thanks to our German friends, PS or Pferdestärke is often seen, and Kilowatts or KW, is often seen on tuned cars in Australia. Trawling the net you find a lot of car enthusiasts talking about horsepower and torque, what they are, and which one’s better. But, as a lot of you have surely realised, there’s a lot of fake science being spouted by people who think they know what they’re talking about. Torque is the only thing that a driver feels, and horsepower is just sort of an esoteric measurement in that context. 300 foot pounds of torque will accelerate you just as hard at 2000 rpm as it would if you were making that torque at 4000 rpm in the same gear, yet, per the formula, the horsepower would be *double* at 4000 rpm.
Jan 20, 2018 · The value of horsepower explains how much an engine can accomplish in a certain time period. That is just a basic explanation of the two terminologies.

May 26, 2010 · 3.Diesel engines, because of the weight and compression ratio, tend to have lower maximum RPM ranges than gasoline engines (see Question 381 for details). This makes diesel engines high torque rather than high horsepower, and that tends to make diesel cars slow in terms of acceleration.

Dec 11, 2010 · The vertical axis is torque in Newton meters (N-m). Power is N-m times engine speed. As an example, you should be able to cruise at 35 mph at no more than 10 HP. The contour of constant 10 HP on the BSFC map is a hyperbola. To drive at maximum efficiency using 10 HP is the point where the 10 HP contour meets the red line.

Jan 24, 2015 · HP = (torque x RPM) ÷ 5,252 HP = (420 x 4,600) ÷ 5,252 = 367.8 hp Even better. Since we’re only at 4,600 rpm and the engine is approaching 1 horsepower per cubic inch, we can infer that it will exceed one horsepower per cubic inch by the time it reaches the 5,252-rpm crossover point. Sep 24, 2013 · horsepower= rpm*torque/5252. horsepower is a measure of overall performance, whereas torque measures the power being delivered to the road. taking off you want torque, in higher gears you want more rpm and therefore more HP because the higher gears deliver less torque.
