[QUOTE="thePill, post: 11572820, member: 119504"] I am considering the fact that heat soak is a major concern during spring, summer and fall. My source? Car and Driver on the 2010 and 2011 GT500 during the 2009/2010 Lightning Lap. Heat soak does happen, and when it does, the 2010 GT500 can lose 12-16% of its power. That is 64-86 horsepower lost at the flywheel due to pulled timing. With 32-45 degree ambient temperatures, it would prolong heat soak by 30% (quick estimate). If GM chose to run a free breathing Z06 at the same time, the ZR1 might not look as impressive. I am under the impression that the ZR1 run was to lay down a benchmark for the ZL1. The ZR1 wasn't involved in the press event as far as I am aware of so, it was used to fluff the ZL1s time. If you can compare the CTS-V's heat soak issues, they will directly be evident in the same 1.9l LSA. This is a major complaint with private owners.... This is probably why you see the published ZL1's 1/4 and 0-60 times all over the spectrum, some editors are getting the cars soaked and it has a drastic effect on performance. [/QUOTE]
