CTS Intake - Mishimoto reducer - MST TIP

CTS Intake Flow Test – Part 2

Background:

A previous post addressed testing the CTS Turbo intake as delivered from CTS, which included using the silicone reducer that joins the 3.5″ intake pipe to a 2.75″ turbo inlet elbow.

For the cost of a few dollars a silicone reducer can be purchased that will connect the CTS inlet pipe to the 3″ MST Performance turbo inlet pipe.

Test Procedure:

For this follow-on test the same procedure is used as in the first flow test.

Test Results:

After replacing the silicone coupler and turbo inlet elbow the intake flows 404 CFM @ 28″ of H2O. The before and after results are displayed on the chart:

This new configuration is compared with most other results *:

*Note: Not all results are shown in the chart above because some intakes have been tested in multiple configurations that consisted of different filter elements, inlet elbows, or inlet hoses. The best flowing configuration for an intake brand is chosen to present on the chart.

Conclusions:

Modifying the 3.5″ CTS Turbo intake by replacing the silicone coupler allows the intake to connect to the MST 3″ turbo inlet elbow. This replacement of the original coupler and use of MST TIP resulted in a 10 CFM increase in airflow through the intake.

This modified CTS Turbo intake has produced the highest airflow reading of the Mk7 GTI intake products that have been flow tested.
