good turbo "?" , experts please>>
good turbo "?" , experts please>> so I'm having an argument w/myself, here's the deal, if a turbo has a 4" opening but funnels down to 2.5" and the blades are only in the 2.5" opening (I think you all know what I mean), could you have a reducer from 4"-2.5" and run hard 2.5"piping to a pretty large air filter, would that still supply the turbo w/enough air seeing as how your not accually changing or dropping the true inlet size??
I need some help figureing this out, 50% of me is saying it will work, 25% saying it "might" work, and the other 25% wondering what the f@%k is going on...

in a compressor the inlet needs to be larger then the outlet.
alot plays into the flow on how the inducer gets its supply of air.
it will work though but not as well as if it had large piping into the inducer.

do you think it would be enough to see a drop in psi on a turbo thats allready running in the 90% range?, granted the air filter is quite large...
the turbo in your sig looks like the opening is allmost the same size as the blades take up, the one I'm talkin about the opening is large but the blades are small in the center...

Turbos are really good at blowing, not so good at sucking. Anything that you can do to limit inlet depression at the compressor is a good thing. That being said, no piping/filter at all with an asme cone inlet bell is the best thing you can do. As you put piping infront of the compressor you always lower the pressure at the inducer. Will it limit flow, sure some. The main thing to remember is the pressure ratio you see on compressor maps is assuming the inlet is at ambient. As you lower the pressure at the inlet, your PR will go up for a constant outlet pressure. It may put you in a region of the map that's on the choke line, or drop your efficiency enough to raise IAT's alot. Or it may put you in a better region. All depends on the compressor.
Short answer...
Will it work? Yes. Ideal solution? No.

The simple answer is keep the restriction on the compressor inlet down as low as possible.

I'm going to bring this back TTT. We need a bit more discussion about my last question, if anyone can help!
I have since added the 3" STS duct to relocate the filter, but it clearly is inducing some restriction. Power is affected. So, I am considering a 4" diameter, smooth sided flex pipe and larger K&N. 3" pipe has just 56.25% of the cross-sectional area of a 4", so airflow should be significantly improved.
