Volumetric Efficiency
If my engine has a Volumetric efficiency rate of 85%
this is the most A/F mixture it can pack into its Camber
in its 4 stroke cycle >?
So why is it that if you put on a turbo or Supercharger you can
gain more HP and torque with the same VE rate of 85% ?
You not putting more air in the camber you just precompress it befor
the Intake valve ?
So why does it make more power with same VE rate???

RE: Volumetric Efficiency
So if you had the same amount of air in the mixture and you drop the air temp
and make it more dense would you not have the same effect ?
The new Ford F150 uses the same method and runs the intake charge through
ther Evap to cool the air charge, so it still has the Base 14.7:1 A/F ratio but more
dense with huge power gains ???

I don't know what you are asking.
By cooling the air it becomes more dense. Denser air contains more particles of o2. This means the injectors can spray more fuel to maintain the a/f ratio. By having more fuel and air in the cylinder you are able to create more power per power cycle.
