Forced Induction (FAQS)

[Skunkworks]

Here is some more info for the Roots section..

Check out the efficiency maps

A simple explanation of the isentropic efficiency maps:

During compression, air heats up. Theoretically it should increase temperature by a set amount. The Isentropic efficiency states how close this temperature gets to the ideal temperature.

Since SAE defines standard conditions of 14.35psi and 77 F, The 100% efficent temperatures relative to boost are:

6psi = 134 F
12psi = 179 F
18psi = 217 F
24psi = 252 F

Now you can see why intercoolers are very important. Even with a 100% thermally efficient Supercharger/Turbocharger an intercooler will help!

Great write up, so for a Eaton with 12 psi what would you expect the temperature to be...and the same question for twin screw at 12 psi? (both without intercooling).

I am trying to justify a twin screw just on charge temperature.

Both being plenum mounted blowers there wouldn't be much difference. Intercooled centrifugals give you the lowest temperatures.

good write up

Are forged internals necessary for forced induction?

Chip, thanks for the great info. It will come in handy when deciding which to use on my new Mustang GT.

Hey KBE...man you will so happy with a kennebell 2.6. trust me

what does this sticky mean

Hell of a write up! :read:


<<<<< Applauds!

good post

A lot of useful Info in here. Great write up!

Great read. Definitely learned a lot reading. Very well done.

Have you ever used or heard off ACESIV fuel catalyst? I working with a tuner to see if it does what it claims. Google bnd automotive there is info there.
Thanks for the great write up!

Good info!

That overview was absolutely great. I spent a big part of my morning reading it and now have a much better understanding of forced induction and fuel. Thank you Chip.
