What size hose would you guys run for PCV on a boosted setup?

Gonna run a 3 port solenoid and a hobbs switch. So in vacuum the intake manifold is pulling vacuum on the crankcase. Get 1psi and the solenoid opens and pulls vacuum from the airbox pre turbo.

Think 3/8 will be enough or go ahead and go 1/2"?

 

I think 3/8" would be fine. What sort of solenoid will you be using? Isn't this similar to what STS does with their kits?

 

actually its one of the old ones i had from my old STS kit.
and thinking of it now, i think it has 3/8" barbs?

 

Why not run it from the pre turbo all the time? Thats how its set up on my procharger.

 

I ended up running the factory stuff on the diverside with the checkvalve..
passneger side i ran the valve cover to the air box so it will have clean air and pull vacuum in boost.

forgot to update the thread.

 

Theres no vaccum pre turbo until you get in boost..

 

unless your air filter is completly clogged

 

Could you draw a diagram of your setup? I'm curious.

 

yea.. lemme see if i can work the Paint program..

 

If both valve covers vents are for pulling vacuum, what the valley cover vent for on LS6 style PCV system?

Where is the fresh air supposed to come from to the crank case?

I am planning to put a small breather filter on pass side valve cover and plug the valley cover vent. On driver side valve cover, I might put a check valve or a small breather filter. All other vents on intake and throttle body will be plugged.

Is this setup ok for a turbo truck?
