But we can’t all have massive V8s, and despite the well known phrase “There’s no replacement for displacement”, there really is, and that’s boost! So, let’s explore those points here. The other is a 1.5ltr Formula 1 Turbo engine from the 1980s, which pushes out over 1,000bhp, 800bhp more than the diesel. And this leads us neatly on to the most important point of this feature…. This feature tells nothing but the force applied. The value of torque given in the specifications is the higher value than the actual machine torque. It’s ALL about the powerband Peak numbers might be great for bragging rights, but in most situations they mean very little. Brake horsepower, displacement and 0-62mph time are all key stats when it comes to understanding a car’s performance – but there’s also torque. And that’s something most people probably wouldn’t expect…. To make it more clear let’s take an example of hitting a pole in the worst cases.
On paper, a 240-280 lbs/ft car is 200 lbs/ft… If you care (and you probably don’t as there’s countless calculators online to do it for you), the equation to calculate BHP from torque and rpm is: Torque (lb/ft) multiplied by Speed (rpm) divided by 5252 = POWER. This is why cars with lots of torque at low rpm have good low down performance. There is little doubt they are fast, indeed in a flat-out race they are around the same performance as any other car with a similar power to weight ratio. And while swapping a small turbo for a big one may gain you 200bhp, you might well have less lower RPM power than standard, and therefore be slower than standard up to 5,000rpm.

Hub power figures are lower than crank and flywheel figures, but a little higher then wheel figures. It’s one of the reasons – along with economy – that you’ll find most heavy good vehicles use torquey, diesel-powered engines. In such disastrous cases, some proven maintenance tips can be helpful. It’s not only diesels though. The other gearing option, while often not as cheap, is adjusting the gearbox’s individual gear ratios. Providing you do have the grip to use it, can you really have an engine that has ridiculous amounts of power and torque right across the rev range? A heavier SUV will need more torque to begin moving or keep cruising.

Now you know the right answer to, This is fairly a good combination of speed and the excellence, which one should know to bring the best-, Now that you have all the answers to the question. On the flipside, most cars on the road spend most of their time at lower rpms. As mentioned, flywheel power is the most common measurement used in the UK, but is actually the only one never truly measured. First up though, let’s turn the complicated science of power and torque, in to something basic that hopefully we all can understand…, Torque is the amount of turning force an engine has in one revolution. For example, the Formula 1 V8 engines of the recent past had barely 220lb/ft of torque whereas a standard Mk5 Golf TDI has nearly 260lb/ft, but will a Golf TDI win a race against a F1 car or a Ferrari? Peak power and torque issues are similar. People can judge you with the knowledge you have about daily basic things like the car. Well, the answers to these questions you are going to find here will give you a better look at torque.

No chance. While high rpm only performance is often unavoidable, cars going from no power to an absolute explosion of power in the space of 500rpm, something quite common with big turbo engines, just creates traction issues and makes the car hard to drive on the limit. LIGHTNESS Power to weight ratio is the key to performance, and it’s why cars like Caterhams and indeed many motorbikes, are supercar fast despite having less power than a lot of hot hatches. In today’s world, everyone wants to get perfect. The value of torque given in the specifications is the higher value than the actual machine torque.

Horsepower: James Watt came up with the concept of horsepower — which is a measure of, interestingly enough, power.


Registered Office: Media House, Peterborough Business Park, Lynch Wood, Peterborough, PE2 6EA H Bauer Publishing, However, that’s not the only place power is measured, and the place where it’s measured has a big effect on what number any given engine will show as producing.

Naturally aspirated vs turbo conversion, vs big turbo on an EP Civic Type-R The high revving Honda 2ltr lump from the Civic Type-R is one of the most common examples of a powerful engine with surprisingly little low rpm performance, and one that even with a large turbo fitted, gains a huge amount of both midrange and high-rpm performance, as soon as the turbo starts making any boost pressure at all. Driving a Toyota Land Cruiser: Why Is It Appealing? And where power is the greatest varies too, as peak power is the point where the engine is spinning the fastest while still producing good torque. A top spec Rallycross engine will cost you over £60,000 though…. But it’s always worth revving long beyond peak torque, and in many occasions beyond peak power too. That the car might make 500bhp at peak, but if it still makes, for example, 400bhp after that at even higher revs, it’s still very fast – and is often accelerating faster than it would in the next gear up at a lower rpm! No matter how much deeper you know about your car, without knowing the basics it’s all vain.

More torque also tends to mean a faster 0-62mph time: It allows the vehicle to accelerate faster, in the initial stages of movement when the car is beginning to start or pick up speed. Your desire for a fast-accelerated car can become true if you know a few key points. The reason is exactly the same as previously mentioned. While it takes a talented engine builder to create an engine to the correct spec, it’s amazing how much power and torque a fairly small engine can make at both low and high rpm when it’s running a lot of boost. Having said that, by adding forced induction, be it a supercharger or a turbo, to a naturally aspirated engine that originally has a very small high rpm powerband like the aforementioned Hondas, will actually widen the usable rev range – giving great power from whatever rpm the turbo kicks in, or indeed from idle on a supercharger. More torque also tends to mean a faster 0-62mph time: It allows the vehicle to accelerate faster, in the initial stages of movement when the car is beginning to start or pick up speed. What are the things that are vital to know before you finalize your car are: An engine with capability to output the maximal torque amount over a wider range of the speed of engine. Making it very easy to see if a car has a small high rpm powerband, a torquey low rpm one, or anything in between. This is a job for the professionals and tends to involve fitting a competition spec gearbox. VAT no 918 5617 01 The reason many production cars such as Evos and Imprezas have 0-60 times that are often two seconds faster than front and even rear drive cars with the same power, is they have the grip to use every last bit of it. The powerband issue is magnified with naturally aspirated engines, as fitting wilder cams and so on to an engine that’s already got a narrow powerband may make it so small it makes them almost unusable without a close ratio gearbox fitted. & What’s its role? But as long as you run a sensibly sized turbo and a lot of boost, you can actually even have as much or more low- to mid-range grunt as well. There’s a lot of debate on the accuracy of flywheel figures, and that’s the reason some countries, particularly the USA and Australia, rarely use them on tuned cars. With 450lb/ft anywhere beyond around idle speed, 1,000lb/ft of torque by just 4,000rpm, and well over 1,200lb/ft at high rpm, no matter what gear or speed you’re in, the tyres will just turn to smoke with this engine. Many think there’s no point revving beyond peak power. Instead, I’ll just summarize the basics that are accepted as fact by everyone. Facts and Fallacies! The amount used to turn the power on is what the torque is. Simple, right? To achieve this highest value, the engine must spin at the maximum of a few thousand revolutions per minute (RPM), which come to happen over a limited range of engine RPM. But thanks to our German friends, PS or Pferdestärke is often seen, and Kilowatts or KW, is often seen on tuned cars in Australia. What many= competition cars do is run a longer first gear, as most standard first gears are far too short for performance use, a standard ratio second gear, and closer ratio gears beyond that, giving a lower top speed, but a constant wave of hard acceleration in every gear. It will get obliterated. Conversely it’s why big busses and trucks are slow, despite having more power than most supercars. This is often a straight swap, and you can drastically improve acceleration, meaning that while your top speed may only be a little, or possibly no lower, you will get to these speeds faster than even increasing the engine power by quite a large amount would achieve.
