pcv/brake booster vacuum
When changing from a q-jet to a holley is it ok to run both the pcv and the brake booster off the one large port on the back of the holley?Will this work?I was going to run a T off the port going to both,just wondering what everyone else did since the holley has only one outlet for this size of line.I'm running a vic jr intake so it doesnt have any other place for manifold vacuum.Do I really need the pcv valve?Its going on a street/strip car.Thanks for informing a dummy.

Sorry, they can't share the same port. You're stating your Vic Jr doesn't have a port? HHHmmmmm time to engineer one Bleed off will be to great to operate the booster and in a lot of applications, the engine falters and stumbles when you apply the brakes. And yes, you should use the PCV. Crankcase pressures and moisture are a major concern.What if the "Hokey Pokey" is what it's really all about?
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
