i am curious on how a tubro is set up on a car. not how it works but like what is hooked up to what and etc.. i think i have a pretty good idea but i am just trying to learn and would like to know for sure. any info would be appreciated. thanks guys

 

Two parts, one run off waste gases(exhaust), the other is fed air(intake). The exhaust gases turn a turbine wheel on one side which is attached to another wheel on the intake side by a shaft. As the exhaust gases spin the compressor wheel, the turbine on the intake side forces the incoming air into the motor and compresses it, which allows more O2 to be packed into the combustion chamber. This also raises the air temperature, which is why intercoolers are used.

Same thing with superchargers, except replace the exhaust side of the turbocharger w/ a gear-driven setup that is run by a belt attached to the crankshaft.

 

Here's some information: Some people state that turbos give backpressure. Turbos do not cause backpressure when under boost because when the exhaust vavle opens, the pressure inside the cylinder is much higher then the pressure at the turbo inlet. That cylinder pressure "blows down" very quickly, but it's on the exhaust stroke, the cylinder volume is decreasing very rapidly and from the Ideal Gas Law, that tends to keep the cylinder pressure higher then the turbo inlet pressure. Finally when the exhaust stroke is almost done and the pressures are nearly equal, the intake vavle opens, the intake pressure (under boost) "blows down" into the cylinder and then you have a higher cylinder pressure again.

Another thing commonly believed is that the exhaust turbine is driven by only kinetic energy of the exhaust smaking into it. This contributes to a "little" of it, the majority is controlled by something else...Exhaust pulse exits the cylinder at high temperature and high pressure. It then gets merged with other exhaust pulses and enters the turbine inlet...which is a very small space. So at this point there is very high pressure and heat, so the gas has very high energy level. (Low heat/low pressure/large volume is low energy). As it passes through the diffuser and into the turbine housing it moves from a sall space into a large one. From this it expands, cools, slows down and dumps all that energy into the turbine that's been positioned into the housing so that as the gas expands it pushes against the turbine blades, causing it to rotate. In doing that you just took some wasted energy from the heat of the exhaust that would normally be lost out the back of your tail pipes You can actually measure this effect by sticking an EGT upstream and down stream of the turbo. You'll see a tremendous difference in temperature

 

got ya. but what about how it is set up on the car like what is connected to what and etc... i know that your exhaust goes into them but what are some details after that. thanks

there is a good diagram there that shows how its plumbed

 

cool thank you that was avery helpful website.
