Problem blowing top end seals
My friend has a mini me with a jackson racing supercharger pushing 9ish pounds. I just put brand new plug tube seals and valve cover gasket on it. And a day later it is filling the tubes with oil and leaking badly from the valve cover gasket.It has a catch can on it and is filling it quickly. Any ideas?

Use a catch can with a breather on it. Take a look at what the non-turbo race guys are using, they often have high flow crankcase vent systems to get that extra HP or two from reducing pressure-induced windage losses when it counts.
It worries me that you're getting that much crankcase pressure though, because that means you're either getting a lot of blowby or are pressurizing the oiling system with the supercharger (I can't remember, is the supercharger gearbox oiled by the engine?) but either way it doesn't sound like normal operating conditions.

If you're getting that much oil blow-by something else is wrong.

i do need to find a vented catch can that one he has is a piece of shit. And yea the supercharger is sealed lubrication. i think i'm going to just look for a stock Z6 for him. That mini-me is prolly dying with the charger on it. thanks for all the help though yall.
