Turbo vs Supercharger

[B@nNeD]

With turbo timers they are used because when you shut your engine down your turbine will still keep spinning for atleast 1-2 mins later tha timer give's ya engine oil pressure a chance to stabilize and ensure that your turbo has enough lubrication so it isn't spinning on a dry housing & a dry turbo can cause premiture wear & permanant scouring of it's main shaft
