    Installed mine a couple of week ago and was very easy to fit. Checked after a couple of runs and can was empty. My next run was a few hundred miles and once checked again there was oil residue in the can.
    Looks smart and does the job.

    I have had my JLT catch can on for a little over 1800 miles now. I check and drain it after every trip to the drag strip and then again at every oil change. Last oil change it was about 1/3 full (approx. 3 oz. of oil) so it is definitely doing its job. I think my oil amount may be slightly higher than other drivers because I go to the drag strip at least every other week, I daily drive the car, and I drive like an ahole on fire, so your results may vary lol. :D

    Great product though and very happy I bought it.

    Ordered on Thursday, arrived at my house on Friday. Installed Friday night.
    Good product, fully functional. Hoses are preconfigured so it's a 5 minute install.
    - Pop off the stock hose (2 clips)
    - Use two nuts to secure bracket to existing engine stud.
    - Two screws thru bracket into can lid (locktite).
    - Pop new hose ends onto engine connectors.
    Only drawback is that the bracket material is a little thin (but this does allow you to adjust position).

    My one gripe on all units mounting to engine is that they conduct heat to the can. The JLT bracket while thin still conducts heat but far less heat than a billet aluminum arm/stem. Oil vapor would be more likely to condense faster if the unit was not engine block temps (hot). I'm still pondering remoting my JLT to the fender area or adding some gasket material to isolate the can from the bracket to slow down the heat transfer.

    5 minute install, looks like it belongs there and is catching oil. I'm still under 1000 miles but the can has a tablespoon of oil in it already.

    My only continued question has to do with what would be happening to that captured oil if I didn't have the can. Would it REALLY muss things up eventually, and did FCA REALLY miss this in their engine design?

    I have it because I kinda believe keeping oil out of the supercharger intake is a good thing over time, but its hard to get a definitive answer on this.

    I think over time it wouldnt be a good thing too have oil in the supercharger...I had a 2004 supercharged cobra and had oil in the intake allthe time it needed a catch can bad but ford must have missed that in their engine design aswell along with the FCA

    I'm running the JLT catch can. Collected about a tablespoon of oil in around 1000 miles. Far better in the catch can than the intake

    Why do we think they "missed" it? Maybe it is not actually a problem? :cool:

    Nothing was missed. Emissions regs prevent venting blowby direct into the atmosphere. A separator was included (proving the need especially on this engine and other forced induction motors which generate more blowyby) its just that the OE setup isn't as efficient as it could be.

    Seems most miss the question that should be more obvious to ask (although I guess it's not intuitive, for some.) What gains are there by directing blowby into your combustion process; answer none it's detrimental to peak performance and has the potential to cause hardware problems down the road.

    There is an OE separator on the Hellcats?

    Should be easy enough to run longer hoses and fender-mount it or somewhere similar away from heat...although everything under the hood will be hot/warm.


    You don't want any more oil in your intake air than you must have. It can foul your IAT sensor readings, your MAF readings, coat the inside of your super charger, oil slicked lobes...nobody wants that.

    This is a supercharged, positive displacement motor...use a catch can and keep your oil level topped off, especially during the break-in and early miles.
