Default Stupid question

It's been bugging me for a while.


In another thread, someone mentioned a naturally aspirated C5.

Now, how is that possible, since it has fuel injection, isn't that considered forced induction?

To me, naturally aspirated means a carburetor.

Am I correct?

Or am I just stuck in a time warp or something?


Discuss.

IMO forced induction is supplying air pressure that is above atmospheric pressure, like with a turbo or supercharger. Fuel injection is just a different way of metering fuel into the intake airstream. The air is still sucked in at atmospheric pressure.

Super chargers and Turbo chargers are forced induction.

I understand your confusion. Back in the 60s and early 70s when superchargers and turbochargers were very rare, we always referred to cars with carburetors as naturally aspirated and injected cars were referred to as fuel injected (non-naturally aspirated). Over the last 20 years, with turbochargers and superchargers becoming common and fuel injection being standard, the terminology has changed. Naturally aspirated now means the engine being fed air at atmospheric pressure while forced induction (non-naturally aspirated) refers to air being fed to the engine at above atmospheric pressure, presumably by a supercharger or turbocharger.
