As noted, there are too many variables to give a legit estimate. It depends on things like what "high hp" means, how it is achieved, condition/clearances of internal parts, how the car is used/driven. Sorry, no easy answer to this one...

My Z is stock and this was after after 36 miles, mind you most of it was just moisture. Now with the heat I don't get the water, just the oil.

All Catch Cans are kind of a PITA to install on the LT4 as you have to lift the blower LOL 
The Mighty Mouse is a great set up. I have a great video on my site about how to lift the blower so you can reference that if you need to. Its very well done (I'm a bit biased LOL) if you go to my channel main page and scroll down its in the "custom modification" section.
The only thing I would do is I would not cut into your factory lines. So for the Mighty Mouse system when you run the line to the throttle body. Get a quick connector and it makes the installation really easy, very clean looking, and really easy to put back to stock as no hose is damaged.

I drain my MightyMouse Wild every oil change (7500 miles) and just a couple of ounces come out. I’m blown with a built motor and run it hard quite a bit. No road racing and little 1/4 mile. It’s also mostly water.

Kind of embarrassed to say this but i had about 200 ml of fluid come out .
Lucky i guess for me the catch can is of decent enough size to hold this amount .
You can bet now I'm checking / draining it at least once a month now .
Just drained it last night after approx. another 1,000 km,s of driving , just 3 small drips came out this time
