Ford's NEW 6.7 Power Stroke CCV box tested on the SuperFlow Bench - Final Debate
When I emailed them in the past on the past when this system first came out, they recommended NOT to use with any other manufacturer's products, when I told them about the Mishimoto catch can I had in...


this video is pitching a test that does not represent any characteristics of real world use....
and SPE still says the little gizzmo is a filter which it is not....
but in all fairness...the spe box came close in the shoot out but when you compare the price of the spe box (400) and the new for box (about 90 bucks) why would I pay 4 times as much for a second place product.
This is definitely doable IMO because I have a pretty efficient design in the Improved Racing CCR catch can and if the flow could be made to flow right through my old box... hmm... my gears turning now.

as far as the spe box goes...once the concept of the map air driven newer ccv box is understood the spe box would probally be easy to adapt to accept some type of venturi ....45 degree hole...tap the hole with threads...install a fitting...connect to the map to obtain positive pressure.

SPE came out with this flow test to rebuttal the ccv shoot out video in which spe was second to the latest version ccv.
the shoot out video has various ccv things installed and the test artist used a vaccume guage mounted to the crank case to measure actual crank case pressure. The latest ccv from ford out performed all the other ccv’s.
A couple of questions:
1. At 17:34 (in the video) you said:
2. I am trying to understand why SPE decided not to include the CDR valve regulator on the recirculating box. Honestly, if the CDR was on the SPE box, I would have bought your box a couple of months ago hands down, but ended up going with the Ford OE box instead. I would like to understand why SPE decided it was not necessary.
3. So, maybe a silly question, but you are showing vacuum pressures pulling from the intake side, but how does this translate to handling crank case pressures coming from the crank case side?
4. This is more of a thought... I like that you taped off most of the mesh at the end, but I wonder is that a true apples to apples comparison of when the entire mesh screen starts to become coated in oily vapor and residue, like in real-world conditions? Sure, the parts taped off were completely blocking air flow, however, the part remaining was still completely new, unobscured mesh. In real world use, the entire screen is covered, some parts maybe more than others, but there will be no pristine section of mesh to allow completely unobstructed air to flow through. Unfortunately, the tape will not mimic this at all, and I don't see how it actually draws any sort of useful conclusion.
When it comes to bench test vs real world test, it's not hard to understand that there is indeed almost infinitely more variables that absolutely will come into play. However, I do believe that both tests and understandings are valuable information to have at hand, and while the real world test can yield many different results due to many different, and changing variables, I do typically tend to lean towards real world testing for more real-use data, as opposed to what a product can do on a bench when all conditions are set up perfectly and in the most optimal situations. (This is also my reason for question #1, was the Ford box in this video completely new and unused?)
Red did a great job with his video. He ran all brand new CCV boxes on the same truck, back to back. So while that truck is indeed not my truck, this information does indeed give me an idea of what these products will do when they are the best they can be (new) and how to expect that they will immediately perform in the exact same real world situations, on a real truck as opposed to a bench. Don't take this comment the wrong way. I am not trying to dog SPE, I am simply trying to understand. As I mentioned above, I almost bought this SPE recirculating box a few months ago, but went with the new Ford OE box instead (which I wouldn't say is "a pile of crap" - clearly it's not the best option, but it's better than their previous versions, and has tested better than the SPE box in real world use). Some back story here, I had actually just bought the SPE CCV delete and catch can kit, however, I ended up having to come to CA for a year. Due to the ridiculous restrictions in this state, I decided to store the delete kit for now, but still wanted to swap out the CCV in my truck since it was almost 4 years old. The lack of the CDR valve on the SPE kit pushed me to the Ford CCV box. When I get back to FL I want to go ahead and put the delete kit on, but I am still thinking hard on this SPE recirculating CCV instead. I am not sure if I want to deal with smoke or smell from the delete kit, and I love that I can easily clean this filter and would not have to worry about replacing the actual box again. But, I worry about the absence of the CDR valve...
Would love for someone from SPE to respond and answer these questions. Thanks!

A couple of questions:
1. At 17:34 (in the video) you said:
I just wanted to clarify if the Ford box you are running in this video is indeed a brand new, never installed or used CCV box? By your wording I am trying to understand if you are just comparing 2 brand new boxes, or if you are saying that the first time you ran this test you used a brand new box, but this box in this video is not brand new.
2. I am trying to understand why SPE decided not to include the CDR valve regulator on the recirculating box.

And truthfully, I have no clue about these things either.
The guys who do a CCV reroute don't have to worry about excessive oil in the intake air charge because they reroute obviously...
I just don't want to have to crawl under my truck to empty a reroute catch can... the CCR can I have is about 90% efficient at filtering oil out of the blowby gases.. I'm good with that...
The only reason I liked the SPE box is it can be disassembled and inspected.
As to the latest CCV box, I came across info on XDPs website that recommended 30k to 40k miles service interval for them.
Lots of info here

Honestly, I sorta hate that I have spent over $500 on their delete kit and the catch can considering I still don't know what I really want to do. However, I will likely go ahead and install it when I get back to FL, but I am preparing myself to very likely want to switch it out if I start seeing or smelling smoke.
I dunno... lol! I have wondered and been back and forth more about the CCV than I have anything else so far on my truck!

That said, I more than likely will order one of the 23 CCV boxes and install. When is anyone's guess... I have lots more going on.

Because I'd really like to cut the top off my original box and see what's in there, oil wise, but photos have already been posted here of one cut open... I can mod mine I'm sure but no way of getting it back open to inspect it to see what collects inside after modding it, cleaning it inside and reinstalling.
But I'm thinking I will buy a latest gen box to run so I can cut open my old one. Then I have 30k to 40k miles to play around with.
