When plan A fails, try plan B? Since the validation of the newest +General Motors on the road course and race track failed big time and Nurburgring lap time became the quintessential pipe dream for +Tadge Juechter and C7 Z06, the plan B was taken to the streets, with so called roll racing. At this time, it is already beyond obvious that plan B failed miserably, just like the plan A failed before.
Apparently, it is time for plan C... Plan C involves taking the flagship to the drag strip and scoring both countless and impressive victories over variety of competitors. Unfortunately, this plan is failing just as the previous plans.
For a successful quarter mile run, there have to be two components satisfied, one being the time and the other, trap speed. So far, either one of these elements remains a tough objective to meet and while the time element occasionally can be conquered, the issue of the end trap speed remains a case of wishful thinking, with the car failing to achieve the 130 mph benchmark, something that the previous ZR1 had no issues with, with less horsepower to boot.
There are two parts to the trap speed, power and weight. IF indeed, the dyno results presented by so called tuners do hold up during the real life track run, then the obvious explanation why the new Z06 sucks so bad in trap speed numbers has to be related to the weight.
As illustrated in this example, with the car ALLEGEDGLY producing over 660 rwhp (over 800 at the crank), the new Z06 should be reaching about 132 mph at the end of the quarter mile but it reaches only 128 instead... Being conservative again, assuming total car weight with the driver at about 3750 lbs, there is a difference of about 300 lbs to make the numbers make any sense. If indeed, there is no lost horsepower here, then there is only one explanation that makes sense here: the car gains about 300 lbs worth of DOWNFORCE during those quarter mile runs...
No question about it, either the horsepower gain is readily lost off the dyno and on the track a or there is shitload of downforce kicking in at the worst possible time for this new porker. The reality? It is most likely a combination of both, tuner failing to provide SUSTAINABLE horsepower gain and the newest flagship literally weighing itself down due to the totally ignorant and outright stupid application of downforce generating aerodynamics.
