Would you purchase this for your N54?

    Hey guys, we were able to take a very high quality Valve cover breather, and with some custom parts got it to fit very well on the N54. A Valve cover breather is common on 99% of high horsepower builds, and very important on big boosted motors. If you have no catch cans, and are just VTA like a lot of Single Turbo cars, this will 100% ensure no crankcase pressure under boost, while its one way check ball ensures the crankcase is sealed under vacuum. If you have a single catch can, at high boost it is most likely overwhelmed, and cannot vent all crankcase pressure resulting in power loss, and possible turbo drain, smoking issues. (We run dual catch cans, and are installing this on top of those to ensure no CC pressure as we plan to run a ton of boost) IMG_0435.JPG IMG_0436.JPG IMG_0437.JPG IMG_0438.JPG IMG_0439.JPG IMG_0440.JPG

    The breather consists of 3 different Stainless Mesh screens, and a high quality check ball, a filter, and Valve cover grommet to ensure a tight seal. We have these on both our shop cars, but may make a few more if anyone is interested. The price would be $199 if enough interest was shown.
     
  2. Sounds like a cheap and simple option for a lot of people!

    Couple more photos of the internals. Very simple design, 1 moving part, 3 mesh screens to knock down the oil, so only vapor escapes during venting. IMG_0441.JPG IMG_0442.JPG IMG_0443.JPG IMG_0439.JPG
     
  4. You have a sample batch you'd be willing sell and get some testers floating around? I'd be interested.

    Honestly, not really we do enough testing in house to show it works, and a Valve Cover breather is nothing new, pretty standard on most platforms. If there is no interest we just throw them on our cars, and call it a day. Just wanted to get a feeler.

    How would a person know at what point this would become worthwhile? Power/boost levels?

    Well on many platforms this is an entry level upgrade along with a catch can. The reason the N54 never got one is because of the stupid Valve cover design. These are worthwhile at any power level, but become required or at least highly recommended in our opinion at high boost levels

    So what needs done to the VC?

    I run 2 catch cans but I agree that this would be good for single turbo guys that run 1 catch can or maybe none at all! It's really a good idea to make sure the crankcase has a chance to vent properly.

    Looks good Tony! I had this on my Cobalt when I was making some decent power back in the day lol.
     
  11. I just posted that we need these a couple days back. ran them on my last 2 vehicles and it is great. looks good too
     
  12. Make sure it has a check valve/ ball inside to prevent oil coming back up
     
  13. I akso ran vented catch can and a modded pcv plate to run a catch can from
     
  14. Has anyone dumped into the exhaust post o2 sensor? I know on the e36 platform people were going from VC to catch can to exhaust using venturi to pull pressure.
     
  15. Also interested in what modifications have to be done to Valve cover.
     
  16. It should just screw right in. Mines did on my last car. I woukd send you a link to how it works but not trying to cut throat and ruin sales for anyone. This is not new by any means basically

    Looks like it should relieve a lot of the pressure in the crank case, nice job guys.

    Yes, can't remember the exact findings but I think it's marginally better than nothing but not as good as plumbing into intake tract/single filter.

    Is this beneficial for guys with stock turbos? I would like to see it incorporated in the metal valve cover that's being developed

    As far as what needs to be done to the VC, its not simply screwing it in because our VC doesn't have any place for it, and is plastic. VC has to be removed, a specific sized hole is drilled into it, the grommet we provide is inserted in the hole, then the breather is pushed into the grommet, which is locked then to the VC from the inside. This assures a perfect seal, and a positive engagement in the VC.
