I was involved in a discussion on another forum about catch cans and there effectiveness. When I mentioned I was using the UPR can I was pointed to a thread on a F-150 forum where a head-to-head comparison test was done and the UPR didn't fair too well. After going through 15 or so pages it was apparent it was an older design prior to the 3 chamber one they have today. Even after pointing this out, it was suggested that the Elite Engineering would still do a better job than the UPR.
Well, I'm stubborn and I suggested proving me an Elite can and I would perform the same type of testing to prove that my UPR was just as good. To my surprise, they did.
They have provided a used/demo can that has been installed in-line on the output side of the UPR can. Whatever oil and contaminants get past the UPR can (and would have ordinarily gone back into the engine) will be caught by the Elite can.
I'll run this configuration for several weeks and then switch it around, with the Elite can in front and the UPR catching what the Elite misses. I will be noting mileage, general weather and driving conditions and amount of old caught by both cans over that time period. I'll also take part in a couple hpde events where the cans should really shine and 'do work'. I'll drain and measure them before and after each event; I really hope there is nothing either time in the second can.
The main difference you'll see between the two cans is the two outputs on the Elite can. One goes to the normal location on the intake and the other goes to a new port/nipple right at the throttle body in the coupler. The reason for this was explained best explained by someone else:

So here are the install pics (I'll update with some better ones in sunlight when I can). Keep in mind it isn't the prettiest setup, fitting two rather large catch cans in the bay isn't the easiest of things to do and I wasn't that concerned about looks for the testing.3 connections are for the following:
Center is the inlet from the crankcase. All vapors run through.
1 outlet is for the intake manifold vacuum that is used for the primary evacuation of the crankcase.
2nd outlet is for when intake manifold vacuum drops to zero due to reversion pules cancelling it out. This is during acceleration and WOT operation so this system uses the suction available just upstream of the throttle body. These systems eliminate crankcase pressure from building during acceleration and WOT when the damaging combustion byproducts settle and mix with the oil as they are not being evacuated.
So, a few things happen:
1. Eliminating crankcase pressure, especially during acceleration and WOT results in a much more stable piston ring and this less blow-by. = more power by eliminating the parasitic loss of battle the pressure on the piston down-stroke.
2. Engine oil remains cleaner longer by always evacuating and removing the damaging compounds as soon as they enter the crankcase as blow-by while still in a gaseous or suspended state. As the PCV system comes from the factory, it only utilizes IM vacuum to accomplish this, so the contaminants entering will quickly settle and mix with the engine oil and remain their and accumulate. This is the main source of wear in an engine today, the water, sulfuric acid, abrasive soot/ash/carbon, unburnt fuel, etc. that is what blow-by is made up of. Once mixed with the oil, most is there to stay and as the oil filter can only trap down to 15 microns sized particles, the vast majority of these are in the 2-7 micron range and will constantly circulate and cause wear.
So, this is the next best thing to a belt driven vacuum pump system (which is best) but they won't live long on the street. This type system not only drastically improves on the OEM PCV systems functions, it also traps 95% plus of the oil and other compounds where the average "catchcan" only traps 15-30% so a great deal still gets drawn past them. Also, the test stoli is conducting anyone can perform to see just how well, or how poorly any "catchcan" actually works as most only judge by seeing oil when they drain the can, they have no idea how much actually is just "pulled through" a can to still be ingested.
You want to stop all oil and other contaminants from ingestion as anything but air/fuel in the combustion chamber results in less energy released by negatively affecting the burn rate, burn pattern, etc. as well as the KR results from detonation caused. If you delete, or defeat the PCV system you are allowing all the contaminates to remain in the crankcase and also are allowing pressure to always be present (even with breathers) so the engine will last a fraction of the time it will with removing these damaging compounds.
So, hope that helps!
