Aspiration Types
Aspiration (Turbos and Superchargers):
Essentially what most aspiration types, other than
naturally aspirated (No turbo), do in a car is spin a small turbine to force large quantities of air into
the cylinders, thus creating more torque and horsepower at the higher revs of an engine.
Turbochargers can be broken down into two main categories:
Single Turbos:
Single turbos are great for higher horsepower builds and tend to have a
broader power band than a twin turbo setup. Single turbochargers create more boost psi at the
higher revs of an engine which is useful for quick acceleration and top speed. Single turbos are
great for drag builds which constantly need power at higher revs and/or if you want your car to
have higher end boost/speed.
​
Twin Turbos:
With a twin turbo set-up each turbo only needs the exhaust from 4 cylinders
to spool which means boost throughout the revs vs a single turbos higher rev. The only main
difference between a single or twin turbo set-ups is wanting boost all throughout the revs or just
at the higher end of the spectrum.
​
​
Superchargers:
Essentially all a supercharger does in a car is increases the density of the air supplied using an
air compressor. Both turbochargers and superchargers do essentially the same but go about it in
different ways. Superchargers can be broken down into 2 main types:
​
Positive displacement:
This type of supercharger generally gives you instant boost while on
the gas and provides with much more low end power. This type of supercharger is great for cars
that are meant to be making boost throughout the rpms.
​
Centrifugal:
This type of supercharger is a little different from positive displacement
superchargers. These types of superchargers are set to give boost at higher revs but at the same
time still be able to deliver the same amount of boost at lower revs. For example, say you set the
supercharger for 8 psi at 6500 rpm as the max rev, if you half that rpm you’d have 3250 rpm
making 2.8 psi. These numbers are more meant to understand what is going on but in the game
you aren’t able to set psi levels for certain rpms so you don’t have to worry about that.
​
NA:
This means “Naturally aspirated” which is just a term for a car that does not have either a turbocharger or some form of a supercharger installed on the vehicle.
