Its that time of the year and I've been knee deep in tax papers. Unfortunately, a busy work schedule has me pushing paperwork off to the side until just about the very last moment...for months . Anyways, having the need for a break and curious for the last week about a Borg Warner box sitting by my desk, I decided to forgo the coffee break and just go into my garage to snap some pics...
EFR 6758 w/ a GTX3071R comparo
This is how the BW comes out of the box
This turbo has a 6 blade compressor wheel.
Comp housing w/ DV removed
Here is the very simple DV unit. I've seen these over a decade ago on something else, I cant recall what...
Turbine wheel comparison. The blades on the turbine are thicker but do seem lighter. TiAL is brittle at room temperature so needs the beefiness...
Top view.. The size scale is a little skewed as the BW is definitely longer. Just showing profiling and design...
Turbine housing comparo. Again, the BW has a very long discharge which skews the scale. But they are very similar in size and I would think volume.
I have to say, this makes me want to forget about external gating
Angled merge out of the Inlet throat area.
BW left GTX71R right
Just for giggles, I laid the GTX comp over the 6758 inducer and its pretty much identical in diameter
With a few modifications and boring, the FSI D valve fits
With some turbine flange machining on our end, we'll match it to our manifold setups and test it out.
With some mods to the comp housing
