Description: Here's the ZR1 and the GT-R once again, synchronized just as both enter the long straight of the Ring.Notice how the heavy GT-R was able to keep up with the much more powerful ZR1. I can't explain it but maybe it's a combination of the following:1. The ZR1 kept on going back to around 5000 RPM despite the obvious clear and straight road ahead. The ZR1 peaks its horsepower at around 6500 RPM. If the power curve is linear, maybe the ZR1 is only using 76% of its power at this range (or ~450HP at 5000 RPM). The sudden drops to 5000 RPMs could also be due to the reported head winds.2. In the original video there is considerable air drag noise as the ZR1 reaches fast speeds, compared to the relatively quiet Nissan at the same speeds. The Nissan with the much better coefficient of drag could have an advantage here (don't know frontal area though).And if both ZR1 and GT-R achieved a peak of around 175mph in the straight, both have not really tapped enough from their potential max speed of ~205mph and 193mph, respectively.It's possible that if the ZR1 keeps it to 6500 RPM and without much air resistance, it would have realized a much greater speed than the 175mph we're seeing here, possibly walking away from the GT-R.Another thing to consider is that GM's timer is slow (accumulated to slightly more than 1 sec delay). Assuming that it is caused by loss in timing fidelity in the video transfer (which should be the case, otherwise, one can say ZR1 Ring time should really be approx 7:27), then that means if we fast-forward the ZR1 video to make its timer more realistic, it will have a more significant lead over the GT-R in this long-straight comparison)
