It's nice to see this back on track after being gone for a few days. Thanks for the contributions from everyone.

70monte, I think the new diffuser will help somewhat, but if you can find room for the extension it would help more (in my opinion from just looking at it's volume). And Tuner Boost is probably right regarding the filter material and pull through on the exit side. As I posted earlier, UPR asked me to remove the mesh on the exit side during my tests.
When I found the original UPR was only catching 20%, I was disappointed. Finding the RX can is catching 95% made me feel better, knowing there is a can that will do what I hoped for. I really think the UPR with the diffuser, extension, and mesh removed on the exit side will provide similar results to what the standard RX can does. Just a gut feeling at this point, looking at the huge can, diffuser, etc. Time will tell on that too.

I agree as well that the extension is the most critical to add if you already have the UPR.

I have followed Ford 850's test and it seems that even the RX can is letting some oil through so I'm still unsure of what to do.


I'm probably going to be using the new diffuser that UPR is sending me on my fiancée's car since I still have the UPR can installed on it and see how that works. I won't be putting the mesh in the output side of the can on your recommendation.


Anyway, thanks for your contribution to this subject.

To date, no can ever tested this way equaled the 95-99% the RX catches......the closest we have seen catches 75-85%....and thats with dozens of these same tests done over the years on every can that claims to be effective. To achieve 100% in all applications you will need to move to a Centrifuge style system.

TB, how does removing the mesh from the exit side of the UPR improve performance? Why did UPR put that mesh there if it's detrimental?
I would think that if oil gets up that high up on the walls of the 'clean' side, it's going to get pulled through whether there's mesh present there or not, and that the mesh would slow that process.

I have the extension and diffuser. How important is it that I remove the exit-side mesh from mine?

Believe they are looking to free up volume of MT space since the mesh seems to be the aluminum turnings from machining it ends up overdone with the extension.

Joe@UPR had asked me to remove the mesh. He originally said:
"It seems that the filter media on the exit or outlet sometime allows oil to have a path to collect and be pulled out.
If this is the case for you then you can simply share your results with everyone and they all benefit at no cost."
I did remove the mesh for this last stage, but I won't have anything to compare it to. I think someone running the UPR alone would be best to test it, comparing 'with mesh' to 'without mesh' on the exit side. A close look at the exit hose and fittings should tell the story.

I may have to do that. I am also going to run a longer outlet hose on my UPR.
The tests never end.

I received my new diffuser from UPR today. I installed it in the can that I took off my car. I also took out the SS mesh on the exit side as was suggested here.


I'm leaving on vacation Sunday and we will be driving one of the Mustangs on this trip. I will probably be putting the UPR can that I just put the new diffuser in on whichever car we take.


If we take the 07GT, even though it has the 4.6L in it, it still seems to pull quite a bit of oil to the intake. This car only has 16,000 miles on it and was starting to smoke on startup and is why we wanted to put a catch can on it in the first place. The 07 uses a different catch can part # than the 5.0 can but looking at both, the only difference I see is in the O-rings used. I'm sure that the 5.0 can will work on the 07 car just fine.


There is just no good place to mount the can with the extension on it on either cars so I don't think it's an option for my application. I'm just going to have to use what will fit and see how it performs.

Ok, I finally made it through this entire post last night. I've heard about these cans on DI engines for a while through the drag strip. I didn't realize how poorly these trucks deal with the noxious gasses in the crankcase. @Joe@UPR and @Tuner Boost, where are these other tests that you have done? Links please so I can study this more. While I've never had a problem with my trucks in the past, I would prefer to prevent anything that might be coming up in the future. I don't want a sales pitch of any particular brand, just wanting some comparitibility between the different types/styles. I'm thinking about moving forward with this in the near future.....once I get past the possible lay-offs at work.
@Ford850, Thank you for doing your test. While people can say what they want, I commend you for taking the time to do this test in the manner that you did. Kudos.
