Few would debate that past generations of the Ford Taurus was unspectacular and ordinary as a loaf of bread. But the new Taurus SHO (Super High Output) is trying to shake the dull image with the vibrancy of a very potent 365 hp motor. But the Ford offers more than just power. One of the main selling points is that this new Taurus has the power of a V8 engine and the fuel consumption of a V6, in this case, a 3rd 5 liter “EcoBoost” V6. As Ford has succeeded, that an ideal compromise between horsepower and efficiency, and between the strike agitation and utility? It was certainly not new, innovative technology, more advanced technology. They have simply done what most car companies Hat (including themselves) in the late 1970s and early 1980s as a response to the energy crisis: It has a turbocharger (two in the case of the new SHO) to an existing engine their lineup. Turbochargers are allowed to use automobile manufacturers on clean, efficient, and small four-cylinder engines, without sacrificing it completely power. But abated since the energy crisis and obsession with efficiency and fuel consumption in the early 1990s, naturally aspirated V6s and V8s (made without the turbo) its triumphant return. Only a few manufacturers like Audi / VW, Volvo, and perhaps ubiquitous, Saab, continue the proven formula of small turbocharged engines. And who knows, familiar with its legendary Saab’s fuel efficiency and it is no coincidence that their cars use small turbocharged inline-fours almost exclusively. Has no doubt that roared back today on his way to turbocharger into the engine bays, and this time it seems that to be here and stay. The new turbo-charged engines are much more performance oriented than their predecessors and have found their way into the sports car found rather pedestrian ones. Budget imports such as Subaru WRX and Mitsubishi Lancer Evo, and servants, such as the Dodge Neon SRT-4, use all turbos. The immense popularity and affordability of these cars, its reputation for thrilling performance, and films like “The Fast and the Furious, which are rich in naturally aspirated cars chirping of the blow-off valves, a whole generation of car radios lusting after that colossal screw created lurking under the hood. Above all, turbocharged, in its various manifestations to such a popular modification as it is by far the best bang-for-your-buck, assuming you know what you are doing, of course. A large intercooler behind the striking front bumper is presenting the “pshh” sound of a blow-off valve between the switch and the heady, jet-turbo spooling sound of all bonuses, all tastefully tuner with alarm the fact that your car is packing a lot more import than the average . Obviously, a turbo kit a desirable upgrade for all to expand significantly their car power. But what exactly is a turbo, and what is so special about it? At its most basic level, a turbocharger is driven simply an air pump / compressor from hot exhaust gases . On non-turbo engines, the exhaust from the engine without interruption by an exhaust manifold (s) and through the rest of the exhaust system and out of the tailpipe. A turbo engine is a bit more complicated. With such a machine, instead of flowing across through the muffler, exhaust first trip by an exhaust manifold (turbo manifold), which leads the collection and forward all of the exhaust gas in a large opening of the turbo to the exhaust turbine (see figure below). From here are some of the gases flow from the back of the turbo through a downpipe and out the exhaust like a naturally aspirated engine. But the majority of the hot exhaust gases flow into the turbine, and thus the moving air spins the exhaust wheel (a small metal fan with many leaves) in the exhaust gas turbine. This moving air causes the wheel to rotate very fast, sometimes as high as 120,000 RPMs. The exhaust wheel is sitting on a shaft rotates with it, on the other end of the shaft, there is another bike, as the compressor known. The wheel turns in exactly the same height as the turbine in the exhaust, but it has nothing to do with the exhaust gases. Instead, ambient air is determined by the turbocharger’s inlet pipe, where the fast moving compressor compresses the truest sense of the word, the air above the drawn atmospheric pressure, and then sends out the outlet of the compressor, where it then flows to the inlet of an intercooler on the way to the engine throttle body and intake manifold.

The amount of compressed air that is very different, depending on things like the obesity of the inner parts of the engine and the fuel and engine management systems. This amount is measured in pounds per square inch, and is generally known to increase as “too.” Thus, low boost is about 5-10 bar (above atmospheric pressure), average increase of about 10-15 bar and high boost pressure is 15 -20 + psi. While this is a great oversimplification produces more lift of a particular machine produces more energy. In general, an increase of about 10 HP every 1 psi increase accompanies increase. At first go it is obvious that a lot of power can be carried by the support, only 5 psi, the engine was still producing about 50 horsepower more than when they do not have a turbocharger. Compare this performance with that which was represented by a series of expensive, difficult to install camshafts on a non-turbo engine, which could make the engine 10-15 hp more, and it is obvious that turbocharging is the way to go for serious performance increases. Be sure to check back soon to the Raleigh-tuner-car side for the step-by-step process of charging of the engine of a Nissan 240sx, and thus increasing power from 155 to 400 +!
