High HP turbo catch can setup
 

I have a Jegs catch can ready for install, not sure how to go about installing it. It will vent to atmosphere. Any suggestions or sharing your catch can install would be appreciated.

Update 7/27/14
Finally got around to doing a mock up of how I want it. I bought an aluminum bar from home depot. Decided I was going to use the battery tray bolt to mount it. Lifts the battery slightly, but not noticeable in my opinion. It is wobbly, but once the lines are connected and I zip tie them to something or themselves I feel it should be pretty stable. I want to eliminate the PCV valve and run direct to the catch can. Once I find out the the thread size on the block I can then order the appropriate -an fitting. I will be using -6 lines from the PCV block opening and the front vent under the ac comp.

Final install I will also use DEI black wrinkle paint on the bracket and catch can. I will eventually change out the filter to a K&N also.

Let me know what you think.

Vibrant part #'s if anyone is curious to replace the PCV Valve with a -AN fitting:

• Vibrant Part No: 10222 - Straight Adapter FItting; Size: -6 AN x 3/8" NPT
• Vibrant Part No: 10221 - Straight Adapter Fitting; Size: -8AN x 3/8" NPT
• Vibrant Part No: 10223 - Straight Adapter Fitting; Size: -10 AN x 3/8" NPT

i just run the crankcase breather to a filter (vent to air) and for the pcv i cap the intake manifold and run the line from the pcv itself to ground. if you wanted to use a vta catch can (like d3pe or similar) you'd just run both lines from the block to the catch can and cap off the intake manifold (and intake tube if you still have a nipple there for vacuum).

I think James pretty much nailed it. I didn't see if you had it installed or not this weekend, but I would just run the PCV line off the back passenger side of the block to the catch can. If you have another opening on the can, then run the breather line off the front driver side of the block to the can as well. Then I would run anything that needs vacuum directly off the nipple on the back of the intake manifold where the PCV used to run to. I have pictures of my D3PE and vacuum manifold setup if you want to see it.

Yeah. I was going to run both to a catch and just block off the manifold ports.

Please share your pics.

I can't seem to find them. I might have to take some new ones.

I have the same Catch Can as @King Tut , maybe we can meet up on the weekend or something so you can see it. Let me see if I can find pics of mine.

I use the manifold port that was used for PCV as my vacuum/psi signal for gauge and BOV.

Don't run your PCV line to the ground for the sake of others on the road and their is also un-burned fuel in that mix you will be leaking on and near hot engine parts.

Also blocking off your intake manifold PCV line will affect your vacuum line pressure and thus your idle and potentially your tuning.

wat? How is capping the port on the back of the intake manifold going to do any of that?

The intake manifold is under vacuum, the ECU is adjusting for this vacuum. It is also variable, based on load.

If you block off the port you are changing the vacuum pressure/IM pressure. (Simulating a clogged PCV Valve)

The ECU responds by adjusting fuel trims. And the idle will also drop.

I agree with your first statement. I still don't see the blocking off of that port changing the amount of vacuum that the engine develops at idle. I will have to plug mine and verify this.

Yeah. I would love to check it out. Let me if you going to a local meet or we can just meet up.

This applies to any car with a variable PCV system. I went through a lot of this with my catch can research talking to radium about the importance of flow testing cans and making sure they maintain a proper seal.

PCV system is apart of engine design and ECU tuning straight from the factory. The vacuum is factored into the normal air fuel balance. So by plugging the port the port on the intake manifold it will cause as much as a 50-150 change in RPM drop. It can also cause fuel trims to change or ECU to trigger a more rich condition.

Bottom line is that Intake manifold was designed to take incoming blow by air flow from PCV and use it. Thats the point of the valve being variable.

Don't plug the hole on the IM. And don't vent your PCV line straight to the ground, it will spray oil and unspent fuel all over the under body or on the pavement.

Here is my Full blown Catch can

Yup that's what I wanted to do.

You have pics of the other connection in the front?
