Integrated Engineering V2 Intercooler Flow Test

Background:

Integrated Engineering has released an update to the intercooler that they produce for the Mk7 GTI. The V2 intercooler is tested for airflow performance using a flow bench.

Test Procedure:

The flow bench calibration is first checked and then the IE intercooler outlet pipe is attached to the flow bench using an adapter that connects to the stock size charge hose.

At the intercooler inlet another stock size hose is attached with a bellmouth at the hose entrance.

The flow bench is operated at a test depression of 28″ of H2O and the airflow reading through the intercooler and hoses is recorded.

Test Results:

The IE V2 intercooler flows 242 CFM @ 28″ of H2O. This is shown with other stock location intercoolers on the chart.

The following chart shows the IE V2 compared with all other intercoolers that have been flow tested.

Conclusions:

The IE V2 intercooler flows 242 CFM @ 28″ of H2O which is an increase of 25 CFM over the V1 intercooler, roughly an 11-12% gain.

Although the inlet and outlet of the V2 end tank have been reduced in diameter compared with the V1 intercooler, the core depth has increased from ~58 mm to ~71 mm. The added core depth should potentially increase the area of the interior charge air pathways by almost 23% versus the V1 design.

The IE V2 intercooler is the highest flowing bar and plate design intercooler that has been tested thus far.
