Ecoboost PCV issues

Tracey... Thank you for devoting so much time to explain the details of catch cans and various designs.  I have learned a lot that I didn't know.  Great work!  I will definitely want one when fitment is completed.  Please keep us advised.
 
Sat is fast approaching so we will post the step by step pictures and have the system finalized then.

The issue is far worse in the cold temps below 45* F, but even here in Florida, the ecoboost is the worst as far as water and unburnt fuel accumulating in the crankcase and oil due to the design as it only evacuates at idle and low rpms/throttle position. As soon as there is any boost detected the IM vac is shut from the integrated checkvalve in the pass side cam cover so there is no removal of the mix. That is why the RX system uses the inlet side of the turbos for evacuation during boost.

Most PCV systems do just fine, but this is a turbo application and that is where the issues come in with the poor design, and GM is no better with their turbo doing evac during boost only and none at non-boost. All of the water/gunk in the intercooler, the rough running during acceleration, the rapid engine wear from diluted oil (if you see your oil level rise it is from unburnt fuel and water and acid present) is all caused by the PCV system doing such a poor job of evacuating.

I am anxiously awaiting for you to get this to market . When this happens hopefully you will use 4Dr as an etailer  option .
 
Great write up Tracy! Really appreciate all the information. Can't wait for the Explorer kit to get released. THANKS

These will ship in 2-3 weeks as they're made to order by RevXtreme

Awesome! I see the title of the video is not to use the Monster can; I assume this is only for the Flex?? With either size fit the XSport? Also, (I'm sure this is posted somewhere but I can't find it right now) is there any advantage to going with the larger or smaller can? (other than having to empty it less often of course)
Thanks!

JJ… just click on the link and order now without putting it in your cart…. most of your answers are there. Otherwise I'm pretty sure you want just the regular can size and you should consider the clean side separator if you're going to get the can… the info is on Tracy's website (search RX catch can to find the site).
 
I have created/built catch cans/breathers for all of my heavily modified turbo cars from the 80's and 90's but those were primarily to control detonation from the very low 'octane' of the oil vapor being reburned. The RX set up is light years ahead of the 'cans with mesh' things I have been building. Nice work :clap:. I've ordered mine up from EBPP I had no idea that the DI engines were even moreso susceptible than older port injected motors. Great write up on a level that I could understand :-[
 
First ones I ever saw were early Maserati hemi 6 cylinders from the late 50's early 60's (Aluminum alloy block and head, integrated lower engine case/oil pan, 2 spark plugs per cylinder, etc.) very advanced for the time. In road racing they knew that the oil caused detonation....no one understood the rest of the contaminates at that time, but Maserati had a very effective unit back then that used a road draft tube for steady evacuation at speed. It did have to be emptied, and was crude, but it was real innovation from just the road draft tubes using the Venturi effect for suction.

We have always used belt driven vacuum pumps on all our drag engines (app 1000 HP NA running Methanol), but app 15 years ago when we were pushing 700-800 plus hp forced induction, we were always battling detonation and we started using the air compressor units thinking that would catch it, and we still had detonation, so we added 2 in series, later one caught as much as the first. Then we went to the larger ones (company call conceptual polymer sells them as catchcans) and still were not catching it. So we bought the cans on the market, and they were not any better. That lead us to start our own designs, and there have been dozen or so revisions since as we learned what does, and what does not work....(and some help from some science heads on flow dynamics and all the principals of separating liquids, etc.) to end up with what you see today. 

Thanks for the kind words....we also post the competitors that do a good job also, but most other can companies/vendors don't care for us to explain all that is involved and what works and what doesn't.
 
Thanks to Tracy @Tuner Boost and @4DRHTRD; Rx catch can and separator showed up today. Everything looks sweet. Can't wait to get "my ride" (*still unnamed) back from the dealership so I can hook everything up!

Pics to come!
 
Pay attention after the install to see your fuel economy improve and the power gain slightly after this is not being ingested.
