K03 Turbine Flow

After soaking the turbine to downpipe studs in penetrating oil overnight I was able to remove them from the turbine housing so I could mount the K03 turbocharger on the flowbench.

I then went through the same process as I had done with the BW K04 turbocharger, recording the pressure drop through the turbine housing with the rotors fixed.

The composite results of the tests conducted thus far are shown below:

Not surprisingly the K03 hotside flows less air than the K04’s at the same depression.

Next up I will be checking the airflow through the K03 housing with the wastegate door open, like what was done with the K04’s.

Paragon Wastegate Lines

Rounding out the collection of stainless steel lines with AN fittings, (for the time being), are a set of wastegate lines made available through AU Tuning.  Behind the scenes Paragon Performance and Marc (cinesnow on AZ) brought these products to the market.

The set I requested had a slight bit of customization to them, a set of adapters for use on the wastegate actuator lines or compressor housing signal lines that I could attach a pressure sensor to.

These lines look awesome, so much so that I decided to add a photo gallery with close up pictures of them.  It’s a shame they’ll be getting dirty soon, but I’ll drive more confidently knowing these robust lines are in place.
