Fact is air goes into the air tube in a swirl, much like a whirlpool down the drain. Reason is it is being sucked in by engine vacuum/air pulled into turbo's. There is proof and patents for vortice air tubes. As it draws it cools due to lowering psi a matter of atmospheric pressure. Air will divide in the vortice into hot and cold. Fords tube to the turbos split into 2. Inserts may redefine the vortice for each tube. Sirens are made with much the same design only spin. Cummins uses a variable vortice system in its H built turbos. A lot of theory is in these systems and not all of it works good. Varible turbos are still out and being repaired.

Once again, there are so many errors, generalizations, and mis-applied theories here, that it's not worth correcting them all.

Turbo system basic rule #1 fix a 90 degree turn of air to the turbo, it should flow in as straight a path as possible to the inlet side of the turbo. The inlet side can have bends just not 90 degree without a fix.

Well I thought before i read this thread that I knew every aspect about turbos. I guess not. Good thread by the way. My brain is hurting by all the thinking and reading going on here.

As an engineer, I now how you feel.....

35 years ago I couldn't spell engineer, now I are one.......

Can't blame someone for trying, just wish they wouldn't try so hard.....

ebrusher

so, should the Ford OEM Tornadoes stay in or come out????

I actually thought that was "good idea #193", not "rule #1". Not to mention that a whirlygig doesn't do anything to fix losses associated with a 90 deg bend.

Whoa, whoa, WHOA!!! Mike, not all of us are engineers so why use such technical terms as whirlygig? Keep it Layman.

C'mon Mike shown em the relationship between velocity pressure and the associated losses through an obstruction causing mass turbulent flow.
