JDM vs Muscle Car Rivalry

by on November 28, 2020



If you are car fan, you exactly known what is the difference between muscle cars and JDM, but if you are a newbie to car culture let me explain the difference.Well the muscle cars as named suggests those cars has to have big loud engine with high torque, yes it is , most of them muscle cars are fitted with v6 or v8 engines which produce so much horsepower that can play with, these engines are most of the time tuned by the companies to go and race anytime anywhere after rolling out from the factory. Most famous muscles cars in 2020 and before are Dodge Challenger (3.6-liter V6 engine) ,Hellcat (Supercharged 6.2L HEMI® Hellcat V8 engine), Chevy Impala (big block Chevy engine), Chevrolet Camaro (6.2L LT1 V8 ENGINE), Mustang ( 2.3-liter Eco Boost turbocharged four-cylinder engine).

JDM standards for Japanese Domestic Market, these type of cars are made in japan and the main reason JDM car more popular in most countries is because japan cars are build with impressive technology but not like muscle cars these cars can be modified with after market parts without damaging the car, on the other hand it's very hard to modify a muscle car because of the company warranty issues and it's mostly likely to give errors from the ecu if stock engine setup is changed, so most muscle car owners tend to keep the car stock while JDM owners change their setup.Another big reason JDM is popular in most countries are because maintain cost and spare parts cost is low compared to muscle cars and even a owner with a average salary can turn a Japanese car into a race car.

popular JDM cars in the world : Mazda rx7 (rotary engine 232hp) , Toyota Supra (2JZ engine 280hp), Mitsubishi Evolution ( 291hp engine )

Which one suits you ?

if you are looking for a car show off and street race but don't have much technical knowledge, then muscle cars are perfectly fine because when the car is manufactured the engine is fine tuned by the company and you don't need to worry about it, but what you need to worry about is the price, muscles are expensive compared to Japanese cars.

if you're a real petrol head and needs to make a perfect car for you racing activities, highly recommend JDM cars, you can buy a cheap one tailor it for you requirements for a reasonable price and also you can gain some additional respect from car culture if you have a hot ride

hope you like the article stay tuned

NOS and how nitrous helps to speed up

by on June 14, 2020
  In the 1970s, Nitrous Oxide Systems (NOS) demonstrated how to successfully harness the power of nitrous oxide for automotive use. More racers are powered by NOS than any other nitrous oxide system brand. When in its intended state of compressed liquid, nitrous oxide can be viewed as an incredibly dense type of oxygen for usage in automobiles. Cooler intake air is denser and hence contains more oxygen, permitting for the combustion of more fuel and the resulting increase in power. An engine's output may improve by up to 1.5% with just a 10 degree change in temperature. When nitrous oxide is introduced into the intake manifold, it immediately starts to boil at -129°F.If we were dealing with, say, a 400 horsepower engine, we could see a gain of over 30 horsepower from the cooling effect alone. As an added bonus, this cooling effect also helps the engine stay below the detonation threshold. In order to boil, the nitrous has to absorb heat from the intake charge and in doing so has the potential to reduce the intake air temperature by up to 80°.



When a NOS nitrous oxide system is turned on, more nitrous oxide and fuel are added to the initial inlet charge. Although the nitrous oxide does not burn on its own, it acts as an oxidizer, increasing the amount of oxygen available for the new fuel to burn and generating more power. The nitrous oxide molecules disintegrate at 565 degrees F (lower than the temperatures of typical combustion), releasing the oxygen atoms bound to the nitrogen atoms. After being liberated from the nitrogen, the oxygen helps the new fuel burn while the nitrogen that has been released prevents detonation.Because there is more oxygen and fuel in the combustion chamber, the different molecules are packed closer together than they would normally be. This results in a faster burn rate, which requires less timing advance for the best outcomes. Peak cylinder pressure would occur too early due to the faster burn rate without the proper timing adjustment, which would result in detonation and engine damage.

Turbocharger VS Supercharger

by on June 14, 2020

 

The general term "supercharger" refers to an air compressor that boosts the pressure or density of air entering an engine to provide additional oxygen for fuel combustion. All of the original superchargers were powered by the crankshaft, usually by a gear, belt, or chain. Simply put, a turbocharger is a supercharger that is propelled by a turbine in the exhaust stream instead. The first of these, known as turbo superchargers, were used on radial aircraft engines to increase their power in the thinner air found at higher altitudes. They were invented in 1915. First, turbocharger and then turbo were used to abbreviate that moniker.


Which is the best Turbocharger or the Supercharger?

Each has its own set of benefits and drawbacks, and can be utilized to increase power, fuel efficiency, or both. Turbochargers use "free" energy that would otherwise be wasted in the exhaust. While spinning the turbine raises exhaust back pressure, putting some strain on the engine, the net loss is generally less than the direct mechanical load given by driving a supercharger (the biggest blowers powering a top-fuel dragster consume 900 crankshaft horsepower in an engine rated at 7,500 total horsepower).Superchargers, on the other hand, can deliver boost nearly quickly, whereas turbochargers often have a response lag as the exhaust pressure necessary to spin the turbine develops.Obviously, a top-fuel dragster trying to run the quarter in four seconds can't afford to waste time waiting for exhaust pressure to build, so they all use superchargers, whereas vehicles tasked with improving a company's corporate average fuel economy (CAFE) can't afford to waste precious horsepower on blowers, so they mostly use turbo. However, as mild hybridization and 48-volt electrical systems become more common, superchargers powered by freely recuperated electricity conserved during deceleration and braking will become more common.This technology is used by Mercedes-new Benz's M256 six-cylinder engine, which is currently available in cars such as the CLS 450 and GLE 450, as well as the similarly sized and designed range-topping engine in the new Land Rover Defender.

What and HowTurbocharger Works

by on June 04, 2020


Who do we owe turbochargers to? Alfred J. Büchi (1879–1959) worked at the Gebrüder Sulzer Engine Company in Winterthur, Switzerland, as an automobile engineer. His first idea, similar to the turbocharger I depicted above, used an exhaust-driven turbine shaft to power a compressor that blasted additional air into an engine's cylinders. He invented the turbocharger in the years leading up to World War I and patented it in Germany in 1905, but he didn't stop working on better versions until he died four decades later.

Have you ever seen automobiles speeding by you, their tailpipes spewing sooty fumes? It's evident that exhaust fumes pollute the air, but it's less obvious that they waste energy at the same time. The exhaust is a combination of heated gases being pumped out at high speeds, and all of the energy it contains—both heat and motion (kinetic energy)—is being wasted. Wouldn't it be cool if the engine could somehow capture that wasted power and use it to accelerate the car? A turbocharger accomplishes precisely that.If you understand how a jet engine works, you'll have a good knowledge of how a turbocharger works in a car. A jet engine draws cold air in from the front, compresses it into a chamber where it burns with fuel, and then shoots hot air out the rear. As the heated air escapes, it screams past a turbine (which looks like a little metal windmill) that drives the compressor (air pump) at the engine's front. This is the part that forces air into the engine to ensure optimal fuel combustion. A car's turbocharger works on the same principle as a piston engine.The exhaust gas is used to power a turbine. This rotates an air compressor, which forces more air (and oxygen) into the cylinders, allowing them to burn more fuel each second. As a result, a turbocharged vehicle may generate greater power (which is another way of saying "more energy per second"). A supercharger (or "mechanically driven supercharger," as it's officially known) is similar to a turbocharger, but instead of being propelled by exhaust gases via a turbine, it's powered by the car's rotating crankshaft.

Generations NISSAN Skyline

by on May 29, 2020

 1st Generation of Skyline GTR



In February 1969, the legend of the Japanese GT-R was birthed. The "Hakosuka" GT-R, as it was popularly known ("hako" meaning boxy, and "suka" deriving from the Japanese pronunciation of Skyline), was an unusual sight when it was first introduced in 1969. Only 1945 were made by Nissan. According to current estimates, there are roughly 500 original GT-Rs left on Japanese roads.

The Nissan Skyline GT-R was unveiled as a sport performance automobile with four doors during the 1969 Tokyo Motor Show. The automobile was essentially a stripped-down Nissan Skyline with minor cosmetic alterations. The red GT-R emblem was the sole feature that set it apart from a regular Skyline. The original Skyline GT-R had an inline six-cylinder S20 engine that produced 160 horsepower. Since 1970, the automobile has had broader wheel arches to accommodate larger tires. Despite having a lot of under steer, the vehicle managed to win 33 touring events in just 1.5 years, making it the first Japanese sport car to beat its European rivals.

Japanese Domestic Market(JDM)Culture

by on May 29, 2020



You've probably heard the word "JDM" at least once before, whether you're an automotive expert or a newbie enthusiast.It stands for "Japanese Domestic Market" and refers to cars that were made by Japanese companies, obeying the country's regulations. Simple enough. But, Japan is a country like any other, so what then makes these JDM cars so special and sought-after that a whole automotive subculture has arisen around them?

For decades, Japanese automobiles have been a cornerstone of not just the American automotive market, but also the global market.However, Japanese imports in America really became central during the mid-1970s, which would eventually evolve into what we see before us now.

Drifting, tuning, and other "outlandish" automotive modifications soon followed. Before we realized it, every country's imports, notably Japan's, had developed their own culture. The concept behind the JDM lifestyle was simple: import a genuine Japanese sports automobile into the United States.

It may appear simple, but there's a lot more to the tale, such as what triggered it, why Japanese automobiles were ideal for this type of lifestyle, and where the culture is today. Here's the "true" narrative behind Japan's domestic market in an attempt to answer such queries (JDM).
To really comprehend how Japanese automobile culture found its way to the United States, we must first consider what everyone in the United States is so passionate about. Japanese automakers began producing excellent sports cars in the 1980s. The Toyota AE86, the original GT-R/Skylines, and others are examples. Drifting and other types of motorsports gained popularity in Asia not long after.

Until that time, the only automobiles available to Americans were muscle cars and pricey European exotics. These Japan-based sports cars, on the other hand, were the ideal blend of the two worlds: the affordability of an American car combined with the performance and pedigree of a European vehicle. Eventually, those of us in the United States caught on, resulting in the large fan following that exists today around JDM automobiles (and Japan's automotive market in general).
