Oil catch can plumbing with supercharger?

I have been enjoying my 3.2 Carrera with supercharger for about 18 months now with mostly DE track weekends. Last year on several occasions after a track session I found the oil cap popped off and oil mist in the engine bay. Long ago I had removed the breather/PCV system that ran back to the intake and added a home made catch can with small filter on top to atmosphere, but the oil cap is still popping off (even with new cap). Obviously I have extra blow by with the 5psi boost, but apparently the catch can and filter can't handle the volume of air so the oil cap pops off.

Should I plumb a new sealed catch can back to the input side of the supercharger to pull a vacuum on it and help relieve the extra crankcase pressure???

Better ideas?......

Can I ask you a question? Sure, what is it? An interrogative statement that tests ones knowledge, but that's not important now....
