How does a turbocharger work?
A turbocharger is a blower attached to the same shaft as a turbine. The escaping exhaust gases turn the turbine and cause the blower to turn and compress the air going into the engine. The more air, the more fuel can be burned and so the more energy you get out of the engine.
A supercharger works similarly except that it is driven by a belt or chain that is connected to the crankshaft instead of being driven by the turbine in the exhaust.
A turbocharger consists of two fans on the same axle. The exhaust gasses pass by one of the fans and gets it spinning. Then the other fan on the same axle also starts to spin, and that fan is used to blow more air into the engine. With more air going in the engine can also take more fuel, and with more fuel burned the engine makes more power. A turbocharger is an exhaust driven air compressor. It has an intake compressor wheel driven by a turbine wheel on a common shaft. A turbo only makes positive pressure,"Boost" when the engine is under a load and more power is needed. During cruising a turbo is spinning "relatively slow" not making boost and the engine only takes in the same amount of air as if it wasn't turbocharged. If you floor it/ or drive up a steep hill, the exhaust gas/heat spin the turbo faster and the compressor wheel supplies greater than atmospheric pressure/boost to the engine to increase power. The amount of power depends on factors like base engine configuration (stock or modified) engine HP, rpm range, compressor efficiency, inter-cooler efficiency (if it has one). Turbos have compressor maps to use for selecting the correct one for a particular engine. It is a graph of how much air (Usually in lbs/min) a turbo can flow at a given P/R. P/R or Pressure ratio is a measurement of boost, same a BAR, it is the absolute pressure the engine is getting from the turbo divided by the air pressure the compressor wheel is seeing. In a perfect world it would be atmospheric pressure which at sea level the standard is 14.7psi. It will always be less when running an air filter, which you should to protect the turbo from road debris. Boost is the pressure above atmosphere the engine is seeing and can be found by P/R times 14.7 - 14.7. example, 1.5 p/r x 14.7= 22.05 -14.7 = 7.35psi of boost.
General rules of forced induction, that give close /approximate results (there are long equations you can do, to get a more accurate result).
1. To find out how much boost you would need, Take the HP level you want and divide it by the horsepower the engine currently has without boost and that is the "approximate" pressure ratio needed to make that much power. For example: If you have a 300hp V8 and want 450hp, 450/300 = 1.5 or a 1.5 P/R. I say approximate as it will almost always take slightly more boost( usually 1-2psi more) to reach that level do to turbo/intercooler efficiency.
2. Another excepted standard is that it takes 10lbs/min of air for every 100hp, so the v8 in the example would need a turbo (if only 1 is used) that can supply 45lbs/min of air at a P/R of 1. 5/1.6. to make the 450hp.
The blow-off valve should not be confused with a waste-gate. The waste-gate is a device that by-passes the turbine wheel of the turbocharger, limiting the shaft-speed of the turbocharger. Therefore, limiting the boost (pressure) that the compressor generates and keeping the turbocharger from over-speeding. A blow-off valve is mounted in the intake plumbing between the turbocharger compressor and the throttle plate. The blow-off valve is a second safety measure against the turbocharger over-boosting and damaging…

When buying a turbocharger for Nissan Altima 25 liter does it have to be the whole turbocharger system or can it be just the turbocharger alone.?
You would have to buy a whole turbocharger system. I am uncertain if a kit is even made for the Altima 2.5. If the Altima 2.5 is a manual, then the transmission is quite capable of handling up to 300whp. The Altima 2.5 shares transmissions and engines with the Nissan Sentra SE-R Spec-V which has the QR25DE.If you meant the Altima 3.5 with the VQ35DE, then I do believe there are turbocharger kits available.
There are several causes for excessive blue exhaust smoke. These probable causes are: Defective Turbocharger Worn or Damaged Valve or Cylinder Kit 14.10.1 Troubleshooting Procedure for a Defective Turbocharger To determine if a defective turbocharger is causing excessive blue exhaust smoke, perform the following: 1. Remove the charge air cooler inlet duct connected between the turbocharger and charge air cooler. 2. Visually inspect the charge air cooler inlet duct. [a] If excessive engine lube oil…
A turbocharger uses exhaust gases to drive a turbine which forces more air into the cylinders, allowing for more fuel to be burned per cycle, resulting in increased horsepower. Besides performance, a turbocharger can also be used in a low-displacement engine (e.g. 1.6L) to match the performance of a larger engine (e.g. 2.5L), resulting in better fuel efficiency for similar performance. In conclusion, a turbocharger improves performance and fuel efficiency.
A turbocharger consists of two fans on the same axle. The exhaust gasses pass by one of the fans and gets it spinning. Then the other fan on the same axle also starts to spin, and that fan is used to blow more air into the engine. With more air going in the engine can also take more fuel, and with more fuel burned the engine makes more power.
This isn't a very well phrased question as you could mean how much horsepower does adding a turbocharger produce, or you could mean how much horsepower do you get from replacing a factory wastegate on a turbocharger with an aftermarket one. However, neither of those questions can be answered concisely without specifics of the application.
Simply put, a turbocharger uses the exhaust to spin a turbine thus compressing air which is then forced into the intake. A supercharger is driven off the engine crankshaft and forces air into the intake. They both do the same thing but the turbocharger uses the exhaust gases to compress air and the supercharger uses the engine's motion.
Turbocharger is a type of gas compressor. It helps intake of more air thereby increasing the power of the engine. This turbocharger has two major parts the compressor and the turbine. the turbine spins and enables the compressor draw more air. During this process the air is hot and to cool the air compressed the small radiator named intercooler is used.
An axial compressor uses many stages of "fans" with stators to compress air in the same direction as its original flow. An example of this is that of *most* turbojet engines' compressors. A radial (or centrifugal) compressor works at right angles to the airflow's original direction. An example of a radial compressor is the compressor on an automotive turbocharger.
No. There are two types of charger to give the engine more air than it would be able to suck in naturally; a Supercharger and a Turbocharger. The supercharger is an electrically (usually) driven fan that compresses the air. A turbocharger does the same job, but it is driven by the flow of exhaust gases through a small turbine. Thus the turbocharger has a small lag time, for it depends upon engine speed for its…
