    So I have been piecing together a short ram intake for the Jeep because the 16 year old in me is telling me to. I also don't want a CAI because my commute takes me along some very poorly drained Boston roads, and I don't need to risk getting any more water into the engine than necessary. Plus I like the mechanical sounds that you can hear after you install one of these.

    And yes, I visited "THAT" aisle in Autozone. I felt old.

    So when I pulled apart the intake today, I found some oil just before the turbo: 2017-03-04_01-26-16_32433518893_o.jpg
    I looked into the tube and found a whole lot more oil. Kinda hard to see (i only had my cellphone and it was cold and windy) but it is there: 2017-03-04_01-27-07_32865127280_o.jpg

    There was a good sized puddle. I got the Jeep in mid January and have just over 5k miles on it, most of this is highway driving too. So I am a bit surprised at the amount of oil in there. My only other experience with a turbo vehicle was an Audi TT, and it didn't put anywhere near this amount of oil into the intake. A light film, yeah, but never a puddle.

    So along with installing a short ram, I made a catch can: 2017-03-04_01-15-29_32433336593_o.jpg

    I based it on the instructions found here:
    http://mazda3revolution.com/forums/...ld-ultimate-diy-oil-catch-can-under-50-a.html
    I had 90% of the stuff I needed for this, along with all the tools. It may be cheaper for you to go buy a catch can, instead of building one, if you don't already have the bits and pieces.

    The one thing I did different is I packed the tube with stainless steel wool. The fittings are brass 5/8" for the lines running to the catch can.

    This is the final result: 2017-03-04_03-59-15_32435794073_o.jpg

    I'm sure there is a tidier way to do this, but it was very cold and very windy today, and I wanted to be done. I also wanted the catch can accessible so I can easily drain it. There is enough hose for me to actually lift it out of the engine bay and over the fender. I gotta make a bracket for more support for the intake but it is resting where the stock airbox sits.

    Here it is with the engine cover on (yes, my inner 16 year old wanted me to paint the boring engine cover too): 2017-03-04_04-04-44_32406649184_o.jpg

    Whipped it onto the highway and around town. Rechecked all the connections when I got back. Everything ran great and no CEL's popped up. Will have to see if this affects gas milage in any meaningful way. The Jeep goes whoosh-shhhhpsshhh now!

    The parts for the short ram are all Spectre stuff:
    3-2.5" tapered reducer
    3" tube with vacuum ports
    3" 45 degree elbow
    3" 60 degree elbow
    6" cone filter
    Threaded Brass fittings used:
    5/8" for the PCV hose
    1/4" for the other vacuum lines.

    Update!!

    Cleaned some things up, added some angled fittings, and moved the catch can to a better location! 2017-03-11_04-56-51_32541263024_o.jpg

    Here you go! To cut out the exhaust in the video note use an equalizer and cut all frequencies below 250hz . My cell phone mic pics up the low end very well for some reason.

    This is a 3/4 throttle acceleration from first to 5th:



    And if you listen really carefully, at the start and end of this next video you can actually hear the itty bitty turbo flutter the Renegade has if you give it a tiny bit of throttle then let off.

    Sweet sounds pretty nice. Now im curious to see what it sounds like without the exhaust setup you have, for my own personal tastes im not into really into aftermarket exhausts, I just want a throatier throttle with a blow off swoosh.

    Play with equalizer settings and you can cut out the drone of the exhaust to get a basic idea of the sound.

    The exhaust is actually a lot quieter than in the video. The phone just makes it really, really boomy for some reason. I went aftermarket on the exhaust because I ran over something while dodging a wrong way driver, and really smashed the stock exhaust. I would have gone with something probably a bit quieter, but I used what I had laying around. I had a Magnaflow that I took of my old Audi TT before I traded that in a few years ago.

    I do not have a blow off adapter installed. Just the GFB DV+. The swooosh will definitely be a heck of a lot louder if you get the blow-off adapter.

    I don't know how this whole thing sounds with the windows down because it is just way too cold to go bombing around like that.

    Thanks! Make sure you use 5/8" fittings/hoses/piping for the system. I originally used 1/2" fittings for the catch can (just because I had those on hand) and the Jeep threw a couple PCV engine codes. Changed them to 5/8" and the Renegade has been happy for over 2k miles with everything on it.

    My rene came with an exhaust cutout, which I had removed, along with the resonator, but kept the cat. Sounds nice but not obnoxious with a slight mellow snarl when you put the boot to her.
