To EVAC or not, need help

[kinger]

Hi guys, I have filters with the hose running from the crank case to the filters. No PCV nothing, is this the correct routing? What else should I be doing, it seems to work OK but hose is ugly and I can't get pre filters to fit and take them off when they are full of snow and get the ice off of them on the trail. What is the purpose, does the crank case need the vacumn to properly work, I see some guys just run a mini filter right to the atmposhere, what are the draw backs of that? Thanks

No you do not "need" the evac setup but it was dynoed by fredie and it did make a few more hp.

Its hard to tell in your avatar picture but it looks like the fittings in your filters are epoxied in.Mine just push into the filter and pop in place.It was pretty easy to just pop them out and remove the outer wears,well it was anyhow until the nitrous nozzes got mounted in the front of the filters.

What did to use the pre filters with evac setups was take a socket and sharpen it on my lathe like a razor. The use this on a block of wood and let the now razor sharpened socket cut the hole with the use of a hammer.

The PCV valve is an option. I'm afraid this will need to your call.
