Nice.
Looks like they've refined them a bit.
What's all different about the Gen 2 High powers?
So to answer this question as thoroughly as I can as several people have asked and I'm sort of not in the know, I researched what I could and came up with this.
The Gen 2 7675 has a larger and stronger compressor wheel. It's suppose to help with spool and have a longer life with added thrust capacity. That's straight from Precision.
The only changes in the VGT as far as I can tell is that the compressor wheel was changed to a 63mm Custom Bullseye Power Batmowheel and that the housing was modified to fit.
My theory (and a few others who are quite knowledgeable have supported this) is that the Batmo is being used to help spool the VGT even quicker and harder to help light the Big 76 Atmo LP turbo. Most tests on the batmo showed it spooled very well early on and were able light very very quickly. So in essence the batmo is lighting faster and able to help the VGT drive harder to make the PTE 7675 scream hard up top.
But I don't know anything, I'm just a structural steel field engineer. I'm just guessing here LOL
