    • LT4 on LT4 - C7 Corvette Z06 vs. Camaro ZL1 on the dragstrip

      Both of these are said to be stock and as you already know both Chevrolet products are powered by the LT4 6.2 liter V8. The Corvette Z06 and the Camaro ZL1 have similar powerplants and transmission options but the weight of each car is really the difference.


      The Z06 should in theory be much faster weighing 400 pounds less than the ZL1.

      As you can see in the first run, the Z06 struggles off the line and is trounced running 12.74 @ 11.71 to the ZL1's 12.27 @ 124.42.

      Both cars get better burnouts and the second run is much closer. The Z06 wins the race with an 11.97 @ 121.45 but the ZL1 has the higher trap running 12.02 @ 122.61.

      You would think the two would be separated by a greater amount due to their respective curb weights and both seemingly being automatics.

        This is not entirely true. The Corvette utilizes an 8L90 while the Camaro uses the quicker shifting 10L90.

        We don’t know what model year the Z06 is but I don’t see how that means it is not similar in transmission offerings. You may be confusing the word similar with exact.

        If it’s a C7 Z06 automatic, then it’s an 8L90. If by “similar” - you mean automatic - then you are correct. However, I promise you the 8L90 and 10L90 are very different in shift speeds and performance. I encourage you to drop into your nearest Chevy dealer and see if you can talk them into letting you get behind the wheel of both to see for yourself.

        Yep. I understand the Z06 does not have the 10-speed.

        Are they?

        What is the big difference resulting in a performance difference besides gearing? They are the exact same style of transmission.

        The only differences are the 10-speed has one more clutch than the 8-speed. The new electrohydraulic valve body is said to contribute to quicker shifts.

        I haven't seen anything even from GM breaking down the shift times of the 8-speed vs. the 10-speed. They make the same claims for each versus the PDK.

        Do I think the 10-speed is quicker? Probably just slightly, but by how much of a difference over the 8-speed?

        No need, I have seat time and these automatics pale in comparison to the PDK GM claims they are superior to: https://www.boostaddict.com/content....t-Corvette-Z06

        The 10-speed obviously is great but I'd like to see a real breakdown on its shift speed versus the 8-speed.
