Who is using exhaust to pull crankcase vacuum?
#11
What I'm thinking is using the kit I pictured above and using BOTH fittings, running one to each valve cover through the baffled breathers that come with the kit. Then I can route my LS6 valley cover through a catch can and into the inlet side of the turbo (or just through a filter breather). As long as I don't pressurize the crankcase I would think that this would work fine....I'll just have to hook my boost gauge up to the crankcase the first couple times out and see whether or not it's building pressure.

I read somewhere that some guys were running a hose/tube farther down stream, towards the end of the tailpipe, exhaust velocity would be lower... They drilled a hole in the pipe and mounted the tube diagonally, facing the end of the tail pipe, so it would actually suck, instead of forcing exhaust back into the tube....

I think Parish tried the same thing with less than favorble results. Good luck though. Here is a link to his thread.

Perhaps, but like you said, you don't want too much or worse boost, thus the reason for placing it further down stream... The amount of exhaust you probably moving IMO it would more than enough... The best way would be to put a couple of probes in your exhaust and messure the vacuum being pulled at each spot, and also measure any boost, before commiting to a particular location...
