Carbed forced induction question.

Hey everyone.

This may seem like a stupid question but Im just curious. On a turbocharged set up the boost is created and goes through the carburetor, correct? On a supercharged set up the carb is on top of the supercharger and the supercharger basically pulls the air through the carburetor, correct?

SO! What {if any} is the difference between a carburetor for a turbocharged application vs. a supercharged application? Can a conventional carburetor work? If so how high of boost can a conventional carb handle?

Thanks Steve

Hi Steve.
The suck-through system is normally used only on Roots and screw-type blowers because the packaging is easier. They can be bolted right to a dedicated manifold, whereas the bulk of the blowers would make a blow-through system more difficult to package in the engine compartment. Centrifugal blowers normally use the blow-through system, like a turbo.

Although turbos have been used both ways, current thinking has them installed as blow-through. The turbo blows only air, so does not have to be modified for a wet system. The other downside of a suck-through is that you have to use considerable tubing to get to the manifold and the mixture not only falls out of suspension on the way through the tubing, but it also presents a considerable explosion hazard in the event of a backfire or valve hanging open. Also, you can't run wet mixture through an intercooler/aftercooler because of fuel drop-out.

Blow-through carbs must be modified to handle the over-ambient pressure. Do a google search for blow through carburetor

Here, I did it for you.
