Is it a potential problem with how the fuel system/tank is designed ? Would like any insight on where to look for the problem and how to solve the issue?
    There is a software fix coming to correct this issue. Stay tuned.

    Thanks,

    Still digging into that on. We've got a plan to get one of the axles back to take a look at it. I see some long smokey burnouts in my future. Darn

    What recommendations do you have to improve the life of the ball joints in the upper control arms up front?

    Best thing to do is keep the stock ride height and alignment settings.

    Did you guys test the Magnum, or LX for that matter beyond 200mph? Say in a wind tunnel?

    Lots of these cars with aftermarket parts are making power past 6400 rpms and my buddy with an '06 300 SRT8 (without the TCM flash) is able to paddle hold the shift at times to 7000 rpms without a problem. Some of us here are big boys and are willing risk popping a motor (on our dime).
    Sorry, for right now there are no plans to open up the cals for modification. Altough we know many of you are capable ofmaking the right kinds of mods remember the trans is not rated for anything above the production performance output.

    The 6.1L oil pump is a 5.7L Hemi pump with a higher relief spring (the new Eagle 5.7L pump is a different animal with larger rotors). As such the pressure when the relief valve starts supercharging the pump inlet is higher to help with the additional demand of the piston squirters. The only time the lifters will see this pressure is when activated and it should not cause lifter problems.

    I own a 2009 300C AWD, I'm trying to build an AWD SRT8. The new Borg Warner front axle disconect system is both AWD & or RWD!! I would like to drop in a new 6.4 392 VVT MDS when it comes out. Will the Borg Warner transfer case handle the power, can I change the 3.07 ratio to 3.55 or 3.73 LSD with a transfer case performance upgrade & what else would I have to consider to make my 2009 300C AWD, a 300C AWD SRT8?

    Thank you very much

The regional service rep said that this "noise" is a characteristic of the SRT vehicles from 2006-2007. I have driven in other SRT vehicles and did not notice this noise at all. Obviously they thought there was a problem with my car or they would not have switched out all of those parts. I even went so far as to look into the Lemon Law but unfortunately I was passed the alloted time. I dont think this is fair and need advice. Thank you.


    For 2008, there was a check valve change to the shocks which helps this noise. They are retuned for better ride as well, so we suggest replacing all 4 if you want to go this route. The source of the remaining noise is the front upper strut mount in rebound events. We are working on a design change to help the issue, but it will be some time before we will have something out. Thanks to these webchats, we are able to convince management we need to keep working on it.
    Is there a replacement strut mount available yet? If so, is there a way to differentiate the new design vs. old to make sure I am getting the new one?

    Is there a way to differentiate (visually) the revised dampers from the old ones?

    Thank you

    I was just wanting a time line that I could possibly get the redesigned dampers..The dealership has replaced both struts and several other parts, but when showing them the chat answer from before..they are also waiting the redesigned part.....Any thoughts on this

    And thanks in advance..
    Ralph
    Best way to check the parts is the part numbers.

    The new upper strut mounts are now tooled and should be available soon.

The cure recommnded by the vendors for this ailment is purchasing/installing a catchcan.

    During (factory) engine assembly, are the knock sensors raw voltage O/P tested, or even monitored from engine-to-engine? It appears the amount of timing being pulled due to knock sensor activation (real or perceived) varies from platform to platform. Is this normal (it's understood that fuel quality, engine load, atmospheric conditions, etc play a part)?
    Both the 5.7L and 6.1L engines meet all corporate requirements for PCV performance. However, as we have mentioned in previous chats, installing a catch can shouldn't harm anything.

    During end of line testing, output from the knock sensor is verified to be present. Comparing the amount of knock retard between vehicles can be deceiving. As you mentioned there are many factors that affect knock limit. Unless the conditions of your test subjects are identical (highly unlikely), the amount of knock retard can vary.

    Off a SRT that got all the fun go fast bits, but none of the extra weight ?
    Nothing like that right now but there is a Challenger BIW coing very shortly. That with all the bits and pieces out there might make a great road racing project .....

    The 6 speed cars can get a 3.73 or a 3.91 ratio in the diff. On the auto cars there is no option for a 'performance gear'. The magic ratio to gain a little bit of an edge with the auto cars is the 3.23, I'd love to see the Getrag available with this gear set.
