catch can routing

Fuel filter idea bad, stop now.

I like the dual catch can idea though, as long as the can is sealed.

Yes, you want vacuum assisting the catch can under boost. Vacuum pumps on race cars do the same thing.

I've tried a few silly ideas, but I use a cheapo RRE plastic catch can with the filter blocked off creating a sealed can spliced into the pre-turbo maf hose. Works great, I see a little dribble going into the turbo but the exit side of the I.C. pipe is dry as a bone and clean. No dipstick popping issues I can detect.

Do you mean between the VC and intake? If so why?

whats the point of the line to the intake tube if theres a breather on the catch can. wont it be sucking air from that breather which will have no vacum assist on the crack case?

you're on the right track but you need to remove the breather filter, the catch can must be sealed, this is how most newer turbocharged cars come.
