Background:
With the Shuenk IS48 turbocharger using a ported shroud compressor housing, I have had to make some adjustments to the MGM7 intake design.
A significant adjustment is to develop an inlet elbow to replace the Shuenk silicone inlet hose.

With a few more revisions in the books, I conducted a test with the latest version, which has a 3.5″ inlet inside diameter. This is a small increase compared to the previous test, which used an elbow with a 3″ inlet.
Test articles:
Another change from past tests is the use of a smaller Vibrant air filter. Differences in pressure loss between the air filters are relatively minor, and the smaller air filter simplifies fitting the intake in the engine compartment.

The intake used for this test is Beta version 12.
I’m comparing a Racingline air filter attached to the Shuenk inlet hose.

Another product is the Blaze ATOM without the air duct.

Test results:
Flow testing at 16″ of depression produces an airflow rate of 566 CFM compared to the 3″ inlet elbow flowing 547 CFM at the same depression.

The Blaze ATOM flows approximately 100 CFM less, and the RL600/Shuenk inlet hose flows approximately 110 CFM less.
Next:
Further changes to the intake are needed, and I also need to add a PCV port to the inlet elbow.
