Ok so obviously boost pressure is positive pressure in the intake manifold. But my question is, since exhaust gas is always flowing through the exhaust manifold and turbine side of the turbo, (which in turn turns the compressor side of the turbo) does that mean the compressor wheel is spinning even in Vacuume? (just not spinning fast enough to build positive boost pressure?) And since the turbine side of the turbo is on the exhaust manifold, I assume the turbine wheel is spinning constantly? (even when the turbo is not spooled up)
I thought if the turbocharger is not spinning at all in Vac, I could make it last longer by staying out of boost when I don't need it.
Thanks, for helpin me out.
