    Cool To Stick or Not To Stick...!

    Hey thanks for the kind words - I really am happy with it. In the posts above you can see how to do my "Chilly Air" intake mod and port your own throttle body as well, then finish off with a drop in K&N and tune from IPF (requires running 91 octane). That all makes a nice bump in performance.

    Ahhhh. "To Stick, or Not To Stick, That was the question... " (lol) ...when I bought my car as well. That has to be fun! I'm pretty big and have size 13 shoes so, when I tried to get both my sneakers down there with three pedals is was a little crowded. Which is actually funny because my commuter car is a Honda Del Sol and I can Heel and Toe that thing like a Boss! It just has more room down there.

    I have to admit that I don't regret the auto trans (with touring because of the paddle shift buttons, though I could see if you don't have pretty large hands they might be tricky to get at), as it also RPM matches the shifts which is fantastic for grabbing gears in a hard corner. I live pretty close to this road, a section of Hwy 29 which is about 9 miles of absolute insanity and I drift around some of the corners (thankfully I have not seen a cop on that road driving like that... yet). Even as a veteran of such road courses as Laguna Seca, I doubt I could drive this road as fast if my Cadi had the third pedal, but that theory is as yet untested.

    Here is most of that road but I couldn't get all the fun parts into one frame...


    In the end I may still do a custom turbo job to it, but we still drive ours all over the western states. Tearing into the motor seems a little dumb when 95% of the time I don't need any more power and we still have a warranty.

    Re: To Stick or Not To Stick...!

    You're welcome.

    You have great information on mods etc, and I wish we had a freeway like that, wow!

    I feel our coupe's have plenty of power and sometimes I'm surprised so many people post threads about improving performance. I will admit sometimes an auto would be nice when I am feeling lazy, and the rev match is awesome.

    Thank you for the heads up - should be fixed now.

    I absolutely detest what Poogle has done to U Toob - just like when LieSpace got ruined.

    The cai you list are not applicable. This is for lfx engines which they as of yet do not support

    Interesting thing I noticed Last night.. I was putting on my Eibach Kit. and since I was looking at the Borla Exhaust. I wanted to take a peek to see how Involved it was going to be to drop the exhaust.. to my surprise, There is not a single Flange on the exhaust, the entire thing is one welded unit, all the way up to the damn exhaust manifold! Cats pre muffler everything is welded!!! WTH?????? BTW its a 2014 Performance coupe...

    Re: 2012+ Performance Thread For LFX 3.6L V6 Engine - Discussion & Resources

    Sorry I missed this, but here is an example of the testing. After we test we also ask for others to test independently:

    The UPR tested here is the same as the Moroso, Billet Tech, Billet tech, billet prototypes, etc.

    Default UPR vs RX Catch Can Effectiveness Test
    I’ve had a UPR catch can on my 5.0 since last summer. It catches a lot, especially in the cold months. But I’ll get right to my test. I added an RX can inline after my UPR can to see if the UPR was missing anything. And if it was allowing some to pass through, was it enough for the RX to catch anything? I don’t drive a lot of miles regularly since my F150 is not a daily driver, so my results will take some time. This thread is to document how I set it up and what I catch over time.
    I installed the RX can just as the directions explained, but I routed the hoses differently. I left my UPR can right where it’s been for months, but rerouted one hose. I left the hose from the passenger side of the engine to the inlet of the UPR can. Then a new hose from UPR can outlet, routed to the inlet of the RX can. The RX outlet hose goes back to the engine. The PCV exhaust now flows from the engine, through the UPR, then through the RX, and finally back up to the engine intake.
    Before installing everything for the test, I cleaned the UPR can thoroughly. The bottom of the can (inside) was covered with a thin layer of stiff sludge that I could only clean out using gas. I’m glad that was caught, along with the ounces of oil, water, etc, over the months I’ve been emptying it. But I was surprised at the outlet hose from the UPR can. It was wet with oil. Obviously some was getting through the can and back to my intake. I’ve never let the can get close to half full before emptying it. Nearly every time I’ve emptied it, there was 1/4“ or less in the bottom. I’m noting this in case someone thinks I left the UPR get overfilled and it flowed through. Nevertheless, I started this test after cleaning everything for a fresh start.
    I plan to leave this setup on for a thousand miles or so, and report my findings from each can.
    1st picture: UPR can as it was originally installed.
    2nd: CleanUPR can.
    3rd: RX can installed. The hose in the top center of the can is the inlet. The outlet hose on the right has a check valve.
    4th: Engine outlet to UPR inlet on left of can. UPR outlet on right side of can routed around (smaller hose) to the RX inlet. You can also see the other smaller hose coming back up from the RX can and ending at the intake on the engine.

    And the results:


    1000 Miles of Testing Results

    - The Weather has been warmer lately. So the test began with sub freezing temperatures, and gradually increased through the 70's and topped off in the mid 80's yesterday. I couldn't have asked for a better range of temperatures for this test.

    - What they caught was astounding to me. UPR was first in line, with the RX after it to catch anything the UPR might miss.
    The UPR stayed on track with what it has been accumulating for many months. Each time I emptied them, it had about the same amount. It's contents were mostly oil which smelled like used oil. It caught 17cc total which is just under 3 1/2 tsp.
    The RX had more than the UPR each time I emptied them. It's contents were an oil/fuel/water type mix that had a much stronger odor. Not a fuel smell, but a sharper chemical smell compared to the odor of used oil. It caught a total of 67cc which is just over 13 1/2 tsp.

    - Final totals:
    UPR - 17cc
    RX - 67cc

    The RX can caught 4 times the amount the UPR can caught, after the UPR can removed what it could. I said from the beginning I would be surprised if the RX can could pull 10% of what the UPR caught, since it was second in line. If someone told me it would catch an equal amount I would have said BS. For it to catch 4 times what the UPR can caught is unreal


    So, this testing can be done by anyone, and the results will surprise most that think they have an effective can that is really only catching a fraction of what is being ingested.

    And to UPR's credit, they added to revisions, an extension that increases the capacity, and a new diffusser. So they have dramatically improved upon their design. The test of the newest UPR version is taking place now.
