    so, the ZR-1 takes on all at a standing start 1/2 mile. Hits 152 mph in the half mile. Beats several Vettes, but, the Porsche 911 hands the ZR-1 it’s supercharger as the 911 posts a 172 mph. Just an FYI. My bet is the ZR-1 was on traction control half of the way. Power without control is nothing.

    You got that right Racer 86! As you so correctly noted, “power without control is nothing.” And that, my friend, is the crux of the reason why GM is going so radical next year and giving us just a mid engine Corvette.

    I am constantly throttle modulating on my Z06 (exception hot tires, hot pavement on a very hot day), so functionally, I am guessing I am averaging around 525 functional horsepower on my Z06 90% of the time.

      Video and speeds posted were at CorvetteBlogger.com Nov 2 or Nov 3 not sure which day it was posted. ZR-1 laid down several 151-152 mph runs. Beat all the other cars except for the [email protected] 172mph

          I am looking forward to the better traction of the mid engine.
          Enjoying my Shadow gray C8. What a car it is.

            as an owner of 7 midengined cars, both street and race cars, the midengined car has a huge advantage in both traction and also the ability to use more rear brake bias.
            I will wait for the Midengined Corvette, but it’s very hard to do. So many great midengined cars on the market. I love the fact that the ME Corvette is a car that we will be able to work on, and have fun with adding mods at a reasonable cost.

              I’m sure you are correct. I guess we will have to install a race data acquisition system on a ZR-1 to find out the true RWH under actual conditions.
              my bet is under most conditions, the traction control is pulling a lot of horsepower out, and so smoothly that the driver does not notice. Of course, you can turn it off and see if you can get the tires to hook up . As John stated, hot day, hot tires, hot pavement.

                Aerodynamic drag is probably a bigger factor...those rear wings are great for downforce but wreck havoc on high speed drag...

                its not the engine location as much as those wings, spoilers and of course transmission gearing as well...

                engine location would be just about last on the list.

                still lookimg forward to the c8 rear mid emgine vehicle but more so for the tight turn in capability afforded by rear mid engine design.

                  With all due respect, the rear wing drag is a function of it’s attack angle, and Corvette deemed it necessary for high speed downforce. It should have helped with traction from 100 mph and up. Yes, at top speed it adds to the drag coefficient, but 152 mph is not the ZR-1 top speed.
                  not sure what you mean by transmission gearing. The ZR-1 is a sub 4 second car , 0 to 60. 3rd, 4th and 5th gear should be correct for the high speed involved at this event.
                  corner turn in is adjusted by suspension settings. We have to balance the turn in ( lack of understeer) with the possibility of snap oversteer. Any car can be tuned for the desired balance with toe, sway bar rates, tire pressure, camber, caster, spring rates, damper rates and of course , the drivers style..
                  not trying to diss you, but that Porsche running 172 mph to the ZR-1 @ 152 was a big surprise to me.
