A question prompted by the second round of turbo inlet pipe testing was the maximum airflow rate through the adapters. To test the airflow rate a bell-mouth was made to attach to the inlet ends of the IS20/IS38 adapter and silicone coupler. Results The maximum airflow through the IS20/IS38 adapter was 420 CFM.  This is […]

Background A result of the airflow tests with inlet elbows from 034 Motosport, Integrated Engineering (IE), and DBV2 was that the IE did not flow as much as the 034 elbow during the large adapter test. This result was not expected due to the IE elbow having a much larger entry and an exit diameter

Claims: Turbo Muffler Delete, a product that if based on the accolades lavished upon it by vendors would seem capable of improving the performance of the Mk7 GTI.  A sampling of the claims made follows: “Decrease Turbo Lag” “maximum airflow” “eliminates the restriction and turbulence caused by the OEM part.” “additional 10bhp during dyno tests.”
