ZO6 overheating issues ***MEGA Merge***

I wouldn't be surprised if the guy you just called a fool actually helped engineer or design part of the car. He is well known on this board to have inside knowledge and is very informative. Also you're basing your whole point of a few early magazine tests. Who knows how much that MPH improves when it's in customers hands.

Been saying from the very beginning...
First off the numerous video tests that I have seen of the C7 Z06 are very exciting!
Makes me much more interested in trading in my 2011 Z06 based on these reviews!!
That being said, I have mentioned numerous times that with this Z06, experienced car buyers know to either deal with first year "teething" problems like this overheating or to wait at least one model year.
I have purchased over 25 new cars and of those, every single time I went with a new model, for example a C7 from a C6, I have had to spend time at the dealer, speaking to factory reps from the various manufacturers, and telling myself never again to be the Beta site.......
Whether it was Lexus, BMW, Ford, or Jeep, all of them had issues.
My 2011 Z06/Z07, 100% perfect.......
Waited for the bugs to be worked out and drove a base 2008 C6 coupe.
I just knew that the new supercharged engine in the C7 Z06 was going to have something that needed to be worked out.
So for all the Jamokes that will bust my chops for waiting till 2016, I will say this.
Be the first guy in town with the Z06 and just deal with the issues and not whine, or wait.
Simple.

Does any factory cover racing costs?
Racing is expensive and very, very few folks do it on a regular basis.
From what I see at Willow Springs, many of those racing are taking older less expensive cars and beating the crap out of them.......

A bit of fuel on the fire. In 2008 or 2009 i cant remember. Jan Magnussen ran a 1:32 in a Z06 on ZR1 spec PS2's. Put Andy in the same car on MPSC2 and the times would be very close. Better yet, put him in a C6Z07.
155 is super slow for 650 hp. And Pilgrim stayed flat through turn 9 into the braking zone. For GM's claimed 480 lbs of DF, does not justify that speed. A ZR1 with Andy in it would hit 165 or 170.
Its pretty obvious this car will not outrun the ZR1 from a roll (unless zr1 driver shifts like grandma.

Hopefully it was a pre-production tune that pulled too much timing. My old PTA C5 can hit 150 at RA. Now that it's a ST2 car with full aero and 30 more rwhp it still hits 150 with a huge splitter and wing and that's with 390 rwhp.

Bondurant has had overheating problems in the C7s that did not occur in the C6s. Admittedly in Az summer heat (but that was the same for both C6 and C7s) and no C7Z06s yet. Solution was to replace the overheated engine and only run the C7s in the AM in the summer months. There was some discussion of aftermarket radiators for the C7s which of course GM was very much against for obvious reasons. The AM sessions were the compromise.

I guess the old adage still applies. You can't have it all for 78k (+ gas guzzler, lol).
Car is still fantastic, but has limitations. A bit of an identity crisis as this is the track weapon we've all been hoping GM would make, but the SC and heat soak are going to make it a chore to track hard. Especially in hot temps. Not going to be outstanding in straight line performance, will be fast around a track, but will drop off rapidly.
The report from Pobst was that the car lost time on each consecutive lap, same thing happened with Andy, it lost almost a second on the second lap. That's very rapid heat soaking there. And cause for concern if you track regularly. IMO.
Notice on Andy's video how the car goes from 154-155 on the first lap to barely touching 153 on the second lap. Rapid heat soak, no doubt about it. Anomaly? We don't know, yet.

I was really wishing that heat soak would not be a problem on the Z06.
My magnuson powered C5 would pull timing and power like crazy in the summer here in Alabama. Damn shame. It is such a nice car!

actually it got to the 1/4 mile in less time, roughly 11 sec...the ZR1 got there in more time, roughly 11.4 sec. that means in a race the Z06 won, that mean in a race you get to sit on the sidelines. Trap speed didn't get you to the next round but got you a seat to see the next round.

ok, I raced a 2011 GTR from a roll and walked away in my C6Z. BUT the GTR will BEAT ME in a race from a dig because he can do the 1/4 mile in 11.1 and I can do it in about 11.5 or so. BUT his trap speed is about 124mph and my trap was 126MPH. He's got a quicker ETA but I have the better trap but yet I beat him from a roll. Not sure the deal on that but I know cause I did it.

We should WEIGHT until more testing and SOAK in the numbers to see if this is a legit problem.

What is a shame in my opinion is gm went with the small high speed blower for efficiency and economy and then they get crappy epa numbers anyway. Might as well went with hot rodded na engine with lots of cats to get buy emissions. I think a larger supercharger is really going to wake up this car and solve some of the heating problems at the same time.
A larger supercharger would take away viewing area and increase aero drag. Would it run cooler, yes. But what we really need here to have it all is a larger capacity oil cooler.
GM doesn't need to reinvent the car. They just have to offer a heavy duty (secondary) oil cooler as an option.

when you look at the info about the Hellcat Dodge must realize that heat is a big problem and they make it known that the Hellcat can take the heat over a lot of track time..I can't remember what the time is that the Hellcat can run at speed but it is a long time.
