Got my PPI ported coated hotside :)
I got my PPI ported coated hotside the other day & I'll have to say it looks great. The quality apears to be top notch. Thanks PPI. here are a couple pics.
and a pic with its new friend

Nice, how much was taken from each chamber?
Expect increased boost creep if a good amount was removed. The larger area will increase backpressure and decrease velocity near the WG but this can be overcome with stiffer preload. Especially on a standard IX turbo so keep an eye on the backpressure.

Thanks for the compliments Shunderwunder! I am glad you are happy with our work!
I have seen more than a few manifolds and hotsides ruined by people not knowing what they were doing....
That o2 setup looks nice. It should scare the innocent bystanders

question about the dump tube. Is the inside of the o2 housing welded up so that the exhaust side is completely divorced from the wastegate side? I've always wondered if people running these external dumps leave the hole inside of the o2 housing because my only problem with that is the fact that it's going to be a constant exhaust leak even when the flapper is shut. I don't think I'd care too much for that. On another note though, you could have one custom made that would be pretty badass if you ran a full 3" exhaust side discharge from the flange and then a straight dump tube off of the flapper side.
Actually very hard to ruin a manifold.

I never came to this conclusion, just know it's a fundamental law of physics. For more specific info on the topic: "Application of Turbochargers in Spark Ignition Engines" by Wallace William Bester, specifically 3.3.3 and on.
Also, “The passages so formed have an increasing cross-sectional area as the fluid moves through them, the kinetic energy of the fluid being reduced, while the pressure energy is further increased”.

Explain because I know I have done my testing. Never seen any from you guys. Not saying you do bad work but porting is not rocket science.
