The Mk7 GTI intercooler that do88 sells is tested for flow performance.
The do88 intercooler flowed 272 CFM @ 28″ of H2O. This result is shown with other stock replacement aftermarket intercoolers that have been flow tested as well as the stock GTI intercooler.
The do88 is also shown compared with all of the intercooler types and combinations that have been flow tested.
The do88 intercooler measured the highest airflow of any direct replacement intercooler tested to date. The do88 also flows more than most of the bicooler setups that have been tested.
Note: Cooling the charge air is also an important function of an intercooler and that aspect of performance was not evaluated during this test.
Some intake air temperature data logs for the do88 intercooler were provided by a GTI owner.
