How to Choose the Right Turbocharger ?

Usually, the larger the turbo, the more power it can produce A turbocharger is used to gain more power with less gasoline consumed so that the first thing to consider when choosing a turbocharger is how much horsepower you would like to have. A turbo works when exhaust from the engine goes in through the turbine inlet to spin the turbine and by the shaft connected to the compressor, making the compressor wheel spins too, thus, compressing the ambient air and pumping the finished to the cylinders and getting more fuel burned in there. Due to the energy crisis we are facing, turbochargers are making a comeback.

The more exhaust that goes through the blades, the faster the blades will spin, and the engine gets more power. But how to choose the right turbocharger for your car? Don't worry about it. Are there some tips you can easily follow? I would like to give you the help.

The best way to tackle this problem is to have two turbos of different sizes in your car. Perfect, isn't it Although you would like your turbo to be as large as possible, the problem is that your car may suffer "lag", which is the case that the turbo cannot provide an immediate power when you step on the gas. So how to deal with that? The smaller spins quickly to reduce lag when at lower engine speeds, while the speeds get higher, the larger turbo will take over to provide more boost.

Besides horsepower, another thing you need to consider is the temperature. When the turbo works, it can be very hot so that the cooling system must be good, for if not, the turbo may finally burn itself. There are two types of cooling systems: oil cooling and water cooling. One thing deserves to be noted is that while the oil cooling only refers to the oil functioning in cooling only, the water cooling system means the combination of oil cooling and water cooling.

And generally, the water-cooled turbos have a longer life than their oil-cooled counterparts because they can run at lower temperatures. Though the water-cooled one may cost you more compared to its higher price than the that of the oil-cooled one, but it saves you the trouble to replace it from time to time which is money wasting and time wasting.

A turbocharged car also demands qualified engine parts to support it, which means you need to replace your old connecting rods, pistons and crankshafts with ones of better strength and durability.

Making modifications to your car is time-consuming, but once completed, it is really rewarding.
