    I sent Tim K. An email and within 4 hours got a forwarded response from Top of Care. Today I just got a phone call from FCA/SRT.

    At first they thought it was the standard clamp issue. Now they are becoming aware that it is a pressure/radiator issue since talking to me. They are in a fact finding / investigation mode right now with engineering. I explained to him my fear of the radiator letting go like mine did at 150+ mph.

    They seem very concerned and are looking into the problem. Was very nice to get their attention.

    Updates to follow including pictures of the radiator after it comes out of the car.

    That is a good group. Kelley personally responded to one of my mails to Tim and her last month. Glad you posted up a good word about the Mothership. I second it. Thanks also for making everyone aware of a potential problem that could get unsafe also.

    Please keep your old radiator just in case its needed.. Take lots of pictures. Thanks for posting!

    I'm picking mine up tomorrow but I'm not sure if this is a widespread problem or just a few?

    In assuming SRT will want to inspect my rad. Tons of pics though.

    Ya I would hope so, I just don't want it to get tossed out without further inspection by someone at SRT.

    I think they will take this very seriously. It's bad enough having to fit the extra hose clamps. The radiator blowing apart is just ridiculous

    Someone needs to take a radiator not installed in a car pump it full of air,1 lb at a time and see what pressure it fails at.It should hold at least 25 lbs

    Thanks for the update. Maybe part of the problem is the radiator fluid they're using or a contributing factor or cheaply made radiator. Anyway hope to see some investigation results

    Could be an overpressurization issue too. Maybe the water pump is getting overspun.

    Ok here is my prediction on some of the reported issues. Compression is getting into the cooling system via blown head gasket. Potential reasons.
    -Improper break in. (components need seasoning / seating)
    -Computer control detonation isn't as effective with a blower as it is with other arrangements.
    -Running full tilt while low on fuel. If the fuel line pulls air at fuel throttle its game off. The CPU wont catch the detonation.
    -Running full tilt without letting the motor heat up to operating temp.
    The HC motor is a serious race motor. It has a small tuning window. If it was easy, every MFG would be doing it. 11lbs of boost don't seem like much but with this size motor there is a ton of air flow. Also, A minor head gasket leak sometimes wont blow into cooling system until full boost.
    I could be wrong.
