Just a thought, but wouldn’t you want the can hooked up to the turbo inlet so that it will provide vacuum under boost? As it stands it seems like it will only have atmospheric pressure on the crankcase.
I am not following you.


ANother note, that is the first time since the truck had 1000miles on it that the original oil cap is on it, since old RX replaced it. Going to take a min to get used to see that again.
 
The driver side turbo inlet connection (CCV) provides vacuum to the crankcase when under boost. Vacuum actually increases as boost increases.

I was just saying having the CCV line disconnected removes vacuum being put on the crankcase. So as it stands your crankcase will now be atmospheric in and out of boost.

I have read multiple statements, large lines and vent to atmosphere is better and others vacuum source is better as it pulls. I just thought I would try this right now.

Hooking the line up should pull more with the vac reference. I will probably hook a line into, it will only take me a few mins.

Keep everyone updated.
 
The vacuum on the turbo inlet is not much 99% on the time.

Edit, that is also why i said I would add another filter if this didnt smell. It would need more venting space to be best.

The only thing that sucks, Is to get the vacuum at the tube, I will be using one of the factory 90 degree quick connects. Due to the direction of the nipple on the intake tube and the AN fitting bend, I do not think I can run the hose straight to it like I did with the others. The quick connect is much smaller diameter and 90 degree bend on top. Although the large hose is more important for the venting portion, it would be nice to have it att he vacuum point too.

That is true, it will pull more while in boost, but the turbos are still spinning so it will be pulling something.

This has been discussed before and I have tested it. Unloaded at highway speed, it reads only vacuum. On normal acceleration in city, it is very minimal boost level. I still think this would be better at the end of the day vs venting. Venting is just more ideal on race cars in high boost always. I wanted to see how it would work here as mentioned.

Keep in mind, I also be getting extra relief/venting due to gutted PCV.

Additionally, with the fullrace unit being so big (essentially the whole can is open inside) that will also help with relief of pressure. A catch can with small lines on stock PCV system, actually can hinder pressure relief.
 
I added some nutserts into the firewall, so I now have 2 skinny cowl screws plus 2 1/4" or 5/16" bolts. There should be some pictures of my catch can mounting in my build thread, I don't know what page. I can't find any pics on my computer but I'll take some when I get home this afternoon. I can get pictures of my line routing and connections as well

I’d imagine you could probably purchase the Cleanside vent connection on the valve cover and swap that in place of the pcv valve/gutted pcv valve. Saves you from gutting and should have an ID of 1/2.
 
Please excuse the dust... So I drilled out the existing cowl holes and nutserted those as well. So 4 bolts probably 5/16" x 1" long, or whatever the metric equivalent is

@BRoell you got a mini one? lol My RX i had drilled into the passenger tube (selling with kit) i bought a new replacement factory tube. I felt like it has never sealed well where I drilled into it. As I said, my RX served well over the years and has kept intercooler clean.

I threw the rest of the line on last night, with factory quick connect, as well as freshly cleaned K and N. Sorry no pic of that.

Use permatex thread sealant on the bottom of can and at intake.

It is really weird seeing the passenger side of condenser with nothing in front of it!

These are the quick connectors I sparyed fluid film on. They are used if you pull cab. Bottom pic is broken due to corrosion.

Only other Tremor I have seen in person in a lot, this was last year. I saw one once before on other side of interstate. I took a pic of them together. His was trashed.

Is that a custom decal/stripe or oem ?
Factory apperance package. The front diagonal were unique to this.

Any drivability difference after the change on the catch can?
I drove home 2 hrs with the breather and noticed nothing, have not driven with the vac source hooked up. Why would it be different...because the PCV is gutted? I am going to data log this weekend at idle and WOT and see if anything id whacky that you mentioned.

Flashing 93 tune on for the first time this year! Enjoy it a few months. F China!

Yeah I’d imagine with the pcv gutted and now being connected to the turbo inlet, it should pull a good amount of vacuum on the crankcase. SHOULD feel a bit different. If anything should help a lot of crankcase pressure.

Off topic but I notice on 17+ full race switched their design and it looks like the can is now a single valve connected only to the passenger side.


I need to stop saying should.

It's going to feel different with the boost turned up! Ive driven way more miles on 87 than 93 with new turbos. I barely got to use new turbos before winter last year. Only floor it a few times.

Probably because the driver side has a sensor on new trucks, so they just gave up on it.

If running large efr or alike turbos, a competition set of cans with baffles work well, stock turbos full race in my opinion is perfect.
