Dynamometer penis wars - Dodge Viper and Dodge Hellcat versus 2015 C7 Z06 (shrinkage continues for Corvette)

Dynamometer seems to be the favorite place for everyone involved in the greatest high performance fuck up of this century (so far and maybe until Zora or C8? LOL).  Those involve include of course the idiot in charge of Corvette program, +Tadge Juechter , the truly brainless and apparently oxygen deprived buyers, financially disadvanged nut huggers and of course, the piece de resistance, the ever popular Corvette aftermarket "tuners".  As usual, the single digit IQ runs rampant among this crowd, splitting their time between self propagating marketing bullshit, waxing and penis shrinkage based low self esteem.

The matter of continuous entertainment provided by the so called aftermarket "tuners" has been mention in this blog several times and without any doubt, will be revisited frequently in the future.

As usual, competent  aftermarket entitites improving upon the quintessential +General Motors quintessential fuck up called Corvette C7 Z06 is an exception to the very well established already RULE.  As a matter of fact, these exceptions have not happened yet and what these idiots offer to the buyers clearly demonstrates that these tuners should not be even attempting to tune a radio, never mind tuning cars...

Here is another example of this entertainment, with the "tuner" apparently trying to make the Z06 buyers feel better about the piece of shit they bought and inspire them to purchase more warranty voiding automotive snake oil.

In this case, this tuner resorted to the dynamometer tests as supposedly compelling evidence to show the superiority of the Z06, comparing it against none other but Dodge Hellcat and Dodge Viper, two cars that seem to whooping that latest Z06 porker's ass in just any possible way when Nissan GTR is not around? 

As a sidenote, Juechter better hope that Hellcat Hemi does not end up in a Dodge mini van to make the humiliation by the four door super heavy Charger look like the good old days...

Nevertheless, this brilliant tuner chose to show the dyno tests to support his idiotic claims about Z06 being superior to the other two cars.  The only problem here is that based on these graphs, the Z06 is not superior and as a matter of fact, these graphs show how much of a piece of shit the Z06 really is, EVEN ON DYNO, where the impacts of air drag and heat soak are not taken into account...

Here is the dyno run plot for the Dodge Hellcat.  The actual maximum numbers for torque and horsepower are irrelevant (pretty obvious the "tuner" has no clue about this part).  What really matters here is the actual curve and little details like RPM at max torque and hp and slope of the curve with torque and hp dropping while the engine approaches its redline. For Hellcat, the torque peaks at 4500 RPM and is relatively flat up to about 5300 RPM.  The horsepower?  The horsepower keeps climbing up 6200 RPM (limit of the dyno run) with a very linear slope, definitely encouraging taking advantage of near redline shifting (for manual transmission, it should not be the max torque that determines the shift point but the max  horsepower point).  The drop between max torque and torque at max horsepower is about 90 ft-lb.  For a supercharged pushrod, these are truly impressive results, certainly explaining the Hellcat pulling like a train. 

On to the other Chrysler offering, latest Dodge Viper. Normally aspirated 8.4 pushrod is not all that impressive, at least when compared against the previous, fourth generation of Viper but... as normally aspirated pushrod relics go, this one certainly does not disappoint.  The torque peaks at about 5100 RPM, with maximum HP at about 6100 RPM and remaining leveled to 6400 RPM.  The torque drops
about 70 ft-lb between max and max hp.  Once again, this is a good set up, motivating high RPM shfiting and certainly not running out of "steam" as RPMs and speed increase.

And now, here is the LT4 engine.  Right off the bat,  there is a startling difference: the supposedly impressive flat torque maxxes out  at 3800 RPM JUST LIKE A PICK UP TRUCK WOULD!!!  WTF?:  And how how about the horsepower?  Well, it does not really come on until about 4500 RPM only to peak and level off at about 5400 RPM and then actually starts dropping past 6200 RPM.  And how about the torque drop delta?  How about a whopping 160 ft-lb?

When combining these shitty torque  and hp curves, there is one other thing to consider: the area under the curves, it is puny for the LT4 when compared with the other two cars.  Combining this shitty hp and torque and gearing used on Z06 explains very well why this car is so gutless at higher speeds, lacking high speed acceleration.  Was Juechter designing a pick up truck in the first place?  Certainly, this is not something that shoul be present on a high performance car that at least according to Juechter is supposedly a sports car?

Given the heavy weight, this awful powerplant and transmission gear ratios, this is as fucked up as it could get and this is without the effects of heat soak.  Here is a hint for Juechter: check out the gear ratios on the latest Porsche seven speed transmission, may you can get  a trace of a clue?
