I’m going to be installing a pan-e-vac system on the Satellite, and have a question about the location. The directions say to install in the collector just behind the merge. I’d rather put them in the exhaust extension just after the header. Pipe is 3”, same size as the header collector. Will this be as effective as in the header would be? (Approx 3 or 4 inches further downstream)
Before you reply with “don’t bother with a Pan-e-vac setup”, know that I’m not looking for performance, I’m just looking to replace the breathers that currently get the engine compartment all dirty, and perhaps help with any oil leaks. I’ve notice both since eliminating the PCV system a few years ago. I’ve got it, so I’m going to install it.

Do you run mufflers on this car? Is it a street and strip car? If so don't use that system, the back pressure makes it not work well If it is a race only car mounting into the header collector extension near the flanges work well, as long as you have 6+ inches of collector pipe after the valve If you are using mufflers go back to the PCV system and help keep moisture out of the oil

Technically, it has mufflers. But they are Flowmaster FlowFX straight through bullets. I can’t imagine that they create any backpressure whatsoever (??). Like I said before, I’m not trying to seal low tension rings, I’m simply getting rid of the breather setup that I am unhappy with. If it simply accomplishes what the PCV system did, I’ll be happy as heck. Car is technically street legal, but has become pretty much a dedicated race-only car.

Well, maybe I'm just lucky, who knows? My car is a street strip 4 speed car. SFT cam, not too big, 259/266. .600'+ lift. 2" CPPA's with 3" to the back bumper. Magna flows. I run a evac sustem that pulls 5" at idle. No pcv anymore. I did run both at one time. This system works great for me. It can work for you with a straight thru muffler. Any other type of muffler will create an issue. Just my 2 cents.

I sure would like to see a evac pull 5"... are you using a water pressure gauge or merc.. when testing exhaust we use inch of merc(very different)

Just a run of the mill vacuum gauge plugged into the hose at the valve cover. Nothing “Hi Tech”. I have no leaks and I’m completely happy with the setup. The key is the straight thru mufflers and possibly the cam. You can’t have a restriction in the exhaust. Take me at my word or not. No big deal. It can be done and work. My car is proof. An easy way to see if your system is working is to put a piece of paper over the hose at valve cover. If it sticks, you got vacuum. Even 1” of vacuum is good.

Mufflers of any kind reduce the effectiveness of a Vac-u-pan system. Even a collector muffler like a Borla or Dynamax. It will still work, not as well. Exhaust flow across the tube is what makes the vacuum. Placement of the probe matters as well.
The Moroso vac-u-pan specific breathers and check valves along with the tubes with the whistle cut work best.
If the results don't match the theory, change the theory.

I did a study on this when I was back at work.. standard was about 1/4" of vac(merc) at idle and up to about 4-5" of merc at throttle with no muffs round figure... 1" of merc is equal to 13.5" of water
