Background:
A recent post addressed the topic of an inlet elbow I am working on for use with the Mabotech M520 hybrid turbocharger that I currently have installed in the GTI.
Before I proceed with the TIP design, I want to determine whether the part is likely to provide a benefit compared to some commercially available alternatives.
For comparison, a DBV2 TIP and Blaze ATOM inlet hose and flange are tested along with the prototype.
Test Setup:
The DBV2 and prototype elbow are attached to a flow bench adapter sized to match the Mabotech M520 turbocharger’s 60 mm compressor inlet.
An MST Performance inlet hose is connected to the elbows, and a bellmouth is placed inside the hose inlet.
The Blaze ATOM hose is attached to the adapter using the Blaze 56 mm flange. The Blaze duct, filter, and housing are removed, and a bellmouth is placed at the filter’s inlet.
Test Results:
Each setup was tested at 24″ of H2O, and the airflow at this depression was recorded for comparison.
The results for each setup are shown in the chart below:
The prototype elbow (MGM7 / MST) flows approximately 3.7% more than the DBV2 elbow and 2.7% more than the Blaze inlet hose and flange.
Conclusions:
The flow test result described above suggests that the prototype elbow has a good chance of providing some performance improvement over commercially available alternatives.
