I might be insane, but it seems that the truck instantly drove better once the can was installed. gbaumann, am i nuts? did you like your SC better once the can was installed?

You're not nuts at all! When the can is working you're getting more reliable air-fuel across different driving conditions. Also the catch can can "throttle" the pcv vacuum and regulate intake behavior (not an intended consequence but we'll take it!). You want to hear nuts? I've convinced myself that certain gas stations have better gas than others. I now believe that all 93 octane is not the same.Originally Posted by JeepLab
When installing a wide a/f 02 sensor you weld in a new bung into the exhaust for the gauge you keep the factory 02 sensors in place
On the 3.6 the only remote spot to put a wide band bung is were the 2 pipes meet into one by the transfer case which unfortunately is after both cats
I called billet technologies to order the catch can but I didn't know what diameter hoses, lengths and fittings are needed. Any insight on how and where it gets plumbed? Or maybe some pics of connection locations
If you're installing on a 3.6L Pentastar then the PCV port on the rear of the right side valve cover is 3/4". That's where the crankcase gasses exit the motor. The stock connector reduces the PCV line from 3/4" to 5/8" which is the size of the plastic lines running under the hood. Billet Technologies can fit their catch can with whatever size barbed connectors you need. If you mount the can in a remote location then I recommend hard (plastic or stainless steel) lines rather than rubber tubing. Long hoses that get hot under the hood can (will) collapse under suction which will throw the computer off. Oh, and the make-up air return line going into the rear of the left side valve cover is 5/8" (I'm pretty sure).
Reuse the stock rubber elbow connector and use a 5/8" barbed hose coupler to connect a 5/8" hose to it. A quality automotive hose should never collapse. The Prodigy turbo kit uses very sturdy cotton wrapped/reinforced rubber hoses made by Goodyear.
For a boosted system, it's most important to put a catch can on the make-up air side of the system (hose that runs from driver side of engine to air intake), because this is where you'll get oil vapors coming out of the engine and into the air intake, coating the compressor and intercooler, reducing effective octane of the fuel while at high engine loads and boost where you really don't want any knocking to occur.
On the PCV valve side of the system (hose that runs from passenger side of engine to intake manifold), oil vapors only flow into the intake manifold when there is vacuum in the manifold (lower engine load, part throttle, on a boosted engine). It is less critical to remove oil vapors under these conditions.
Of course, the ultimate setup is dual catch cans. One on each side of the PCV system.
can someone post pictures for thier catch can setup? i am not sure how to install the hoses on supercharged engine
thanks
Search my (doc5339) and gbaumann's posts. Sorry that I don't have pictures handy, but I know that both of us posted our setup pictures; gbaumann had a much cleaner setup. They are probably on a Magnuson Supercharger thread on JeepLab.
OK, here's my Frankenstein-version, and it works well:
