This is an “I wonder” test that came about since I first tested the Eventuri intake with a Racingline silicone hose and CTS turbo inlet elbow.
While the Eventuri intake was out of the GTI I decided to see if the flow performance would change when combined with the MST inlet hose and MST turbo inlet pipe.
The procedure for testing this intake setup is the same that I have used for most intakes. The intake is attached to an adapter that simulates the compressor housing inlet of the IS20/IS38 turbo, and this is affixed to a PTS flow bench. The flow bench is operated at 28″ of H2O and the airflow is recorded at this pressure drop.
The Eventuri intake with MST components flowed 394 CFM at 28″ of H2O, a 6 CFM gain over the 388 CFM recorded using the Racingline and CTS parts.
These latest results are shown on the chart below, replacing the previous test results for the Eventuri.
Attaching the Eventuri intake to the MST inlet hose and Turbo Inlet Pipe showed a 6 CFM gain versus a previous test with the Eventuri attached to a Racingline hose and CTS inlet elbow. The difference is small, but greater than the measurement margin of error which is around +/- 2 CFM.
