catch can input/discussion needed

So we have a little homemade PCV pipe (bomb) catch can on the chumpcar. It was perfectly sufficient when the car was NA but now that it is turbo it blows tons of gunk out the filter on top of it, even though the can itself isn't full. I'm not sure if this is completely abnormal but I'm guessing the crankcase is developing a good amount of pressure at full boost/high RPMs.

I realize most people run a line back to the intake pipe (intake manifold on a non turbo car), but based on how much comes out the filter, I'm assuming that would end up in the charge pipes/intercooler and I would like to keep that from happening.

My current thought is to run a hose to a slash cut in the exhaust (to generate vacuum and pull excess pressure/vaporized goop into the exhaust as opposed to spraying all over the engine bay)

I'd like some help/input on possible solutions, has anyone had this sort of problem before? Compression numbers are fine on the motor so it isn't the motor failing.

We obviously can't run a high dollar catch can with internal baffles or anything like that due to the budget limitations of Chumpcar.

Thanks!
