Racingline Intercooler Flow Test

Background:

Racingline manufactures a stock location replacement intercooler for the Mk7. To compare the pressure drop caused by the Racingline intercooler versus other aftermarket options a flow test is being conducted on a Racingline intercooler.

Test Procedure:

The intercooler pressure drop is measured using a flow bench operating at a depression of 28″ of H2O.

Stock inlet and outlet hoses are attached to the intercooler and a bellmouth is placed in the inlet hose. The outlet hose is attached to the flow bench using an adapter that is similar in diameter to the throttle side charge pipe.

Test Results:

The Racingline intercooler flows 241 CFM @ 28″ of H2O.

This measurement is compared with other stock location intercoolers on the chart below:

Conclusions:

A Racingline intercooler for the Mk7 GTI was flow tested and measured 241 CFM @ 28″ of H2O. This measurement is approximately 22% greater than the stock GTI intercooler and 2% greater than the stock Golf R intercooler, comparing favorably with other aftermarket stock location intercoolers that have been tested following the procedure described above.

Note: Airflow and pressure drop do not indicate how well an intercooler will cool. The primary purpose of an intercooler is to cool the charge air. This test does not address cooling performance.

  1. If you haven’t done it already. I’d love to see an experiment testing the differences between the OEM ignition coil pack and a cold ignition pack ie APR, RS3/RS7. Thank you and Happy Holidays!
