Some will, but this is a good mod to make as it does help. The goal is to get as much as possible to fall to the bottom. A rule of thumb on the Bernoulli effect is with the rate of flow through the average PCV system (from 450-650 CFM) and the velocity through any can, is to have the cans interior capacity close to 1 qt to allow the speed of the flow through to slow enough to prevent pull through, and with the outlet location it must be app 4" from any droplets falling to avoid pull through. So good move on UPR's part.

The principal that comes into play is in doing so, it acts the same as if you would take a wet wash cloth, and place it to your mouth. Now suck on it. What happens? Now multiply the flow rate and amount of suction many times what you can emulate with your mouth. This is why you NEVER want any coalescing media against, or near the outlet as it greatly contributes to oil pull through. UPR is on the right track for sure. And the extension is also a must.

With an open header yes, that still works. Not the ideal like a belt driven vacuum pump though, but plenty of sportsman class racers still use the inexpensive Venturi evac valves.....but put any length of exhaust pipe or mufflers on and the pulses will blow out the diaphragm inside the one way valve allowing the crankcase to be pressurized.

If you look at one of our dragsters, on the passenger side cylinder head you can see the pulley for a Aerospace Components vacuum pump. We pull from one bank and have an adjustable vac relief valve on the opposite side as we dont want to pull over 15" or so (over 15" or so begins to pull oil off the wrist pins so we limit it around that point).

This way we not only are constantly evacuating, we also can run a lower tension ring set and the vacuum will pull them to the cylinder wall tighter for less blow by and more power.:



And here is where a breathered can comes in as we route what is pulled into this can to contain the oil/water/etc.:


And the pump closer:


Anxious to see the results. I predict it increased form 20% effective to 75-80% effective. (we have NOT done the test ourselves so this is a guesstimate only)

I also want to see someone test the Bob's. We have and it tested app 30% effective, but that would not be un-biased. A totally unbiased independent test must be done for the skeptics......so 79monte, let me know.

I just noticed that engine is a Dry Sump so that can help pull vac as well.

I already have the fully upgraded UPR can w/ extension and diffuser, which you have already said is around 75% effective, not 20%.

Removing the outlet mesh and running a longer outlet hose on a fully upgraded UPR can should increase it from ~75% effective to ~90+% effective (ballpark figures of course).

Why use a longer outlet hose instead of a longer inlet, or longer length of both?

jgiddy

The inlet hose is going to be dirty no matter what. The longer outlet hose should be the one that helps resist pull-through from the Bernoulli effect.

If I ever relocate my UPR can to the front of the radiator then I will need a longer inlet hose, but until then it's not needed.

Ford850

Ok, I was just wondering since I noticed it mentioned several times.
Note - on my test phases 1 and 3, the outlet hose from the UPR can is at least 30" which goes to the RX can. It didn't seem to make a difference in phase 1 with the standard can. We'll see how the extension, diffuser, and mesh removal affect it in phase 3.

Just looking for some clarification here, if that's ok. Tracy (aka Tuner Boost), manufacturer of the Rx catch can evaporator system, did you buy out Mike (EcoboostPowerParts - located in Arizona), vendor for the Rx catch can evaporator system, change the name to EcoPowerParts (now located in Florida) and are now the manufacturer and vendor for the Rx catch can evaporator system now posting under the username Eco Tuner?

I'm old and slow, so just trying to keep up. Thanks.

My head mechanic at work is looking into catch cans for our F-150 Eco Boost trucks, we have approximately 35 trucks he wants to do, but he is wanting to test a few brands first. It looks like UPR and RX would be the ones to test. Any thoughts would be appreciated.

IMO, if you want a complete solution, Rx is the way to go. I know there's all kind of debating on this issue, but unless you have a setup like the Rx that can tap into the turbo inlet to provide vacuum during boost, it doesn't matter how many improvements have been made to the UPR can, at best it's only going to trap what is being pulled through the evap, and without constant vacuum, not all blow by is going to be evacuated to catch. The only other setup that I've researched that would do the same thing as the Rx is the Elite Engineering E2. I run the EE basic cans on my 2005 GTO and 2011 Camaro LLT DI V6 and they work great for those applications but neither is FI. The Ecoboost turbos, IMO, are spooling quite often, and I'm concerned about the lack of IM vacuum to be doing a good enough job. However, I can't get anyone from Elite Engineering to call or email me back. Most of their applications are GM, so I don't know if they have an install kit for the F150 or not. Not that you couldn't come up with the supplies to install their can, but I would prefer to not have to go through that hassle. The only thing that I don't like about the Rx that the E2 provides is the ability to open the catch can for cleaning. I'm concerned the Rx could eventually gum up on the inside enough to cause problems down the road. However, with no response from Elite in a week now, the Rx is looking like my best option. My truck has 1,700 miles on it now, and I'd like to get this done sooner than later. I'm just trying to figure out who I'm dealing with here as it looks like some ownership changes have occurred. I would also recommend the clean side separator while you're at it to do the entire job right (but, I'm usually OCD when it comes to this type of thing).

Thanks Phantomblackgto,

Per your recommendation I looked at the elite cans also, and the Elite and UPR seem to be better quality than the RX cans, and they are cheaper. Since I am buying at least 35 the price difference adds up. I will see if I can get a response from Elite also.
