Looks like the new CTS-V is prone to heat soak and pulled timing like the ZO6

    For 100k and the thing still pulls timing, are you serious.

    I had a 2010 V making 575 rwhp. I was anxiously awaiting this new V, but the base price of $85k was too much money when the Charger HC was available with more HP for less money. Haven't regretted my decision either!

    I know right! They said it went into limp mode when it get too hot. WTF?! Seriously you can't keep it cool?! Wow that's a huge red flag for me if I was buying it. Ya it's fast but you can't go fast or it will make it go slow....hahaha! Great engineering!

    I've never been fond of the CTS-V styling. I quite liked the idea of the CTS-V wagon though. Just all goes to show how clever the boys at Dodge are.

    I was okay with the CTS V coupe. I am not a 4 door kind of guy. I thought i might sell my ZL1 for its newest iteration/reincarnation in the 6th gen camaro but I may pass since it will be the same LT4 in it like the V and ZO6.

    The fact that it acts like a Z06 should be no surprise. They are the same car, just different skins.

    Yes, but one would of thought with the larger grill allowing more air in the CTS-V would of stayed cool compared to the ZO6.
    But clearly it's an engine cooling issue no matter how much air it's getting around it.

    How GM let this engine to production is beyond me. Did they not heat test it in the desert? Failure if not, and failure if so yet they still allowed it to production even knowing of the cooling issues.

    When Chevy designed the LT4, they put the oil cooler right next to the cats, which obviously gets hot. So while there is much more air being let into the LT4 in the CTS V, there is still thermal radiation from the cats going straight to the oil cooler. The Corvette chief engineer announced a while back that Chevy is working on a fix for the overheating.

    Many owners over on the Corvette forums (which I'm also a member on) have gotten a dual pass radiator (the car should've came with one to begin with) and wrapped their cats with cat shields. Those two things have helped the car out and has kept temps down.

    I really wish Chevy got the cooling right the first time instead of having to spend more time now coming up with a fix. I still think its a great car minus the cooling.

    By any chance, does anyone know where the oil cooler is located on the Hellcat?

    that would be the XLR V (Corvette with a Caddy SC Northstar 475HP) which has been out of production for a few years

    With the extra space offered by the Caddy version of this car, there should room to add the required cooling, plumbing and pumps to keep it happy. I am surprised that there is not a quality kit available to do just that.

    I'm actually shocked by all this heat-soak detuning. GM is fresh off one of the top 2 or 3 engine platforms in HISTORY with the LS and was primed to better it with the LT. I don't recall anyone claiming derating from the LSA or LS9. And here I had dreams of an LT4 in my '57 Chevy or a '56 Chevy. LSA or LS9 with bigger blowers and no detuning look pretty good for now. Long live the LS! PS, I REALLY want an LSA in my '57!

    Suffice it to say every Z06 (except one) seemed to have 20 pound bags of ice on their supercharers at the Texas Mile. I can't say what they ran except for the fella with the Z07 package, and both of his and wife's Hellcats creamed it.

    I think the zo6 failed for the same reason during Motor Trend best drivers car for 2015 test.
