Air filter options on a turbo
Posted by: playerpage ()
Date: May 17, 2020 07:05PM

I know I put up a lot of "I was just thinkin'" questions, but this is something I DO want to get done:

What are the options for increasing the air intake performance on a stock turbo? I have the regular chrome, but it has a pretty tight opening. If I had the tube area cutaway by a machine shop (see pick below, pretend I drew a vent) would that be enough of a difference to matter?

Stock turbo air cleaner is claimed to be a "tuned' device.

In other words no point in doing the cut?

Eric, the Air Cleaner inlet is perfectly FINE just the way it is.
Your breathing restriction is the CARBURETOR!
Compare the square inches of opening on the throat of the air Cleaner Housing to the Throat of the Carburetor.
The Aircleaner Housing is about THREE TIMES larger!
Don't destroy that beautiful Factory Housing in pursuit of performance. (Sell it to me first)
If you don't believe me about the Housing, just take it off, and install one of those slip-on K&N style airfilters for a while, and see if your performance truly improves.

LOL AM

That LITTLE filter would be a restriction for anything but a very small 1 bbl carb.
The filter also needs to be sized for the air flow.

I am glad I made someone smile today! smiling bouncing smiley
Ken, I fully realize that THAT particular filter is NOT what he wants to purchase.
I ASSuMEd (obviously wrongly!) that Eric and OTHERS(ahem. KEN) were intelligent enough to realize that I only included THAT picture to emphasize the point of the TYPE & STYLE of filter I was referring to.
I thought that it was OBVIOUS that the picture was for demonstration purposes ONLY.
I didn't realize that I needed to break it down that far.
My apologies. I will try to make sure that I add a disclaimer statement next time.

If you want even more restriction find the rare option oil bath air cleaner for the turbo.

So I am looking for MORE restriction, not less?

P.S. I have a washable filter. I think it is your example JO. Is that the oil bath one Tim refers to?

No. The optional one was a GM part.

I've run stock paper filters with the stock aircleaner housing, a foam air filter
in the stock housing, a oval cloth KN filter to fit a 45dcoe and a much larger foam air filter for the dcoe that I now use for my EFI set-up. There was zero
difference that I could feel for either filter used with the stock housing, there was zero difference that I could feel between both filter options for the DCOE.
The one air filter related experiment that made a sizable difference was making some really short air horns to replace the standard "long" air horns that came with my DCOE. This worked because the long horns were way too close to the cap on the oval air cleaner housing. Ditch the stock carb!!

Okay. Yes mine is the K&N Style. It's nice to confirm at least there's one less thing I should be tinkering on.
