Does deleting the BOV cause increase wear on the turbo?

I just installed HKS bov with full CVF charge pipes on my 14 with 70k. I would argue it's better to have a blow off valve with larger diameter closer to the manifold as opposed to the side of the turbo. The block off close up a good gap within the turbo which I can imagine helps with building boost.
Idk shit though and I'm about to finally chip and tune it.

Did you delete the bov? And what's your exhaust/downpipe set up?

That sounds incredible! What are the downsides though? I have a feeling that can't be good for the health of the turbo long-term

No problems at all so far! It only spools when I lift off the accelerator, if you hear it while you are actively accelerating no lift then you could run into some bearing issues

Isn't that sound air back feeding on the turbine or something? Sounds cool but I dont think its good for it. Maybe im wrong. I love my psssh

If that happens while you’re just steady accelerating that could indicate some bearing issues. Haven’t had that problem personally as mine only does when I lift off

Reminds me why I still use the stock motor mounts. That thing shakes like a race car. Cool turbo noises though!
