Turbo Charging basics
Turbo charging is one type of "forced Induction". A turbo is an air pump that pushes compressed intake air into the combustion chambers. This charge is far denser than air would normally flow due to atomospheric conditions. When the denser air charge is combine with a greater-that-normal amount of fuel, it will create a more powerful burn, which exerts greater pressure and there-fore increases the engine's power output.
Inside a turbocharger
Inside a turbocharger is a shaft with finned wheels at each end. One wheel, called the turbine, is driven by exhaust gases leaving the engine. The exhaust flowing past the wheel causes it to spin, which in turn spins the wheel at the other end of the shaft, called the compressor. Its the compressor's job to take fresh air and pressurize it before sending it down the intake tract to be mixed with the fuel.
Turbo charger has a couple of advantages over superchargering, the other form of forced induction. Because a turbo ahas no mechanical link to the engine ( like a supercharger's drive belt and pulleys), theres no parasitic drain in power to drive it. Additionally, freewheeling turbochargers aren't limited to or by engine rpm. Plus, turbos are designed to produce boost at higher engine speeds than a supercharger, which makes them well suited to high-revving sport compact engines.

Turbo Timers
Adding a turbo timer, like a HKS model, is a good idea to help prolong turbo life. The timer allows the engine to continue to run, even after the ignition is turned off, so that oil can flow though the turbo and cool it. If hot oil is left in the turbo housing it can solidify (coking) which will leave deposits on the turbo bearings.
Blow-off valves and wastegates
A blow-off valve and a wastegate are desinged to relieve excess presure in the turbo's plumbing, but they operate on different sides of the turbo system. The blowoff valve bleeds off pressure between the compressor and the throttle plates when the plates close but the compressor is still spinning.
Hope this helps if theres any mistakes because i haven't pre-read it p/m me
