I will first start out with saying that this is more of an aesthetic update since we will be making this bell mouth out of a non conventional material
The machine before you is a glass lathe and if coupled with large portions of your life can create some interesting things, especially if you have been doing it for as long as the man that made this for me
I had to use my phone for most shots so they are not the best, but in my defense I needed to help with holding torches/tools and try not to get in the way
Outer body of the bell mouth being established
First cut
Finished outer
Removing excess material
Preheating
Internal portion of the bell being finessed, they use graphite tooling as to not scratch or stick
More finessing
Just like in welding helmets you need to wear shaded glasses at all times so I placed the shades over my camera to see the effect
Measure twice as they say
Cut then flared
Skipped a few steps (I had to hold many, many things) but here it is after the inner and outer pieces were conjoined
I know the glass intake/bell mouth has been done before but I was never impressed by any of them. They basically take a glass tube and flare the end, pretty boring. But now going through this process I understand why. Its ridiculously difficult on all fronts, from the knowledge required to the massive expense of the equipment needed
Its a beautiful thing when an idea comes to fruition
You might be wondering why its two pieces and the simple answer is you cant really do inverted flares with glass. It would create a lot of stress and more than likely thin out so much so that the glass would become unstable
Also just so we are clear none of the actual glass/lathe work is my doing, I would need decades of pure glass experience on an industrial level to do this, it was just an idea I had and was lucky enough to know peeps that did
Any who back to my boring section of the build
As you can see it is complete now and back in my shop!
Basically we kept the mounting simple, just a little flare wrapped in a rubber isolation gasket to keep the glass from touching the turbo
Amazed at how precise this thing is
Now its the turbos turn
Had to cut her down a bit
So I could fit it on the lathes 12in throw
And yes this was as terrifying as one could imagine spinning a turbo housing at 500 rpm, but that ridge had to be machined for better fit dammit!
V band
Machine everything
Worth the trouble for that fit
Preheat then weld time
I don't mean to toot my own horn but I think this tops the Gnar charts
Hopefully this tickles your fancy because it was a stupid amount of work, Oh ya since I love this forum and everyone here so much I also have a video on Youtube that I would definitely suggest watching

I must admit I forgot to add the photos of the one way check valves I installed to prevent said problems. Could it be possible your friend may have installed them backwards? To me that would be the only plausible way you could create a positive pressure strong enough to damage seals and gaskets.
I can say for sure it was mounted the rightway. the issue there is, no matter what way it is installed if you buildup pressure. it will pressurize the breather. altho if you have 1way valve in it then that wont apply, tbh i almost asked that will you add one of those..
In case of normal breather, there is no positive pressure(only little if some) from breather meaning if there is pressure on exhaust it will move onto space where there is no pressure, in this case the breather. In your case, not sure about the piping size, just quessing that the final pipesize is about 4" and the wastegate pipe 2"? and exhaust 3.5"? meaning that even with the 2" wastegate pipe inside the 4" exhaust the area of flow is pretty much the same as 3.5" so it wont have constrict.
4"=12,56"^2 area of flow..
3,5"=9,62"^2
2"=3,14"^2
Bingo, you have to take advantage of the bits that let you get creative, keeps things fun. It takes a little time and money but anyone can do this kind of stuff its just a process
