wow you guys are rough!
gm adds 200lbs of drivetrain to an already very lightweight car and your mad that its not lighter than before?
this is like saying your mad because the 997 gt2 weighs more than the 997 gt3rs! it makes no sense!
wieght light to heavy(aproximations)
z06 -500
gt3 - 430
gt2 - 530
zr1 - 620+
tt - 480
viper - 600
gt500 -500
m6 - 500
sl65 - 600
so which of these cars has the power to wieght ratio stock?

HATE the wheels, not a fan of the sideskirts but I can understand maybe it is a function over form for the kinds of speed it may put down, the hood? eh, there is a window Im guessing so you can see the supercharger? seems like they are trying to go 360/430 Ferrari with the engine cover, but it doesnt have the same affect to me seeing it on a front engine car..
this doesn't look bad though:
I really think they should have changed the front end up a little for give it a little different look, from what they will ask from this car, Id want the overall thing to look a little different from the regular Z06
What would make it great? IMO
Ditch the wheels, burn them
Drop the side skirts or some home integrate them more into the car where it is doesn't look so much like a bolt on.
Ditch the hood window, cowl looks cool, get rid of the window.
Something a little different with the front end, starting to look plain imo..
but maybe thats just me..

that looks very logical to me. both gm and porsche added boost to thier top line performance cars.
both added 150lbs in weight. did you think gm could do something that porsche could not?

The system the Vette uses is much lighter and has substantially better longevity than springs. Apparently you are into unsprung weight in your sports cars?
It uses wishbones front and back and begs the question as to why the Porsche uses a Macperson strut up front?

LOL you guys are going to be eating your words... Not much of a performer huh...
Well they are putting down OVER 620rwtq to the ground BONE stock, and a little over 600rwhp.
Some of the comments kill me, seriously. Internet babbling at it's finest.

The styling is subjective; the performance is not. Looks aside, anyone who owns the ZR1 better have a substantial budget for rear tires.
I love the 4-lobe blower icon on the boost gauge, though, and from what I understand this is Eaton's most thermally efficient supercharger to date, approaching turbo-like efficiency numbers.

Eaton’s new Twin Vortices Series (TVS) is a roots-type supercharger for a variety of engine applications that delivers more power and better fuel economy in a smaller package, for uncompromising, high-performance driving.
The TVS supercharger’s patented design features four-lobe rotors and high-flow inlet and outlet ports that greatly enhance thermal efficiency, deliver higher volumetric capacity, and enable higher operating speeds. The TVS supercharger is capable of running with a high thermal efficiency (up to 76 percent) across a very wide operating range.
The improvements incorporated into the TVS design allow for the use of a smaller supercharger, reducing the package size and weight of the system. The sizes range from 350cc to 2300cc per revolution, and cover engines from 0.6 liter up to large displacement V-engines. All TVS superchargers have a 2.4 pressure ratio capability and a thermal efficiency that exceeds 70 percent, which enables more compact packaging and greater output.
The twin four-lobe rotors feature 160-degree twists. The higher helix angle of the rotors coupled with a redesigned inlet and outlet ports, improves the TVS’s air-handling characteristics without increasing the overall size of the unit. The TVS improved noise and vibration characteristics eliminate additional noise-reduction treatments, complexity and system cost.
The TVS sets a new standard of boosting device performance and reaffirms Eaton’s leadership in the performance automotive market.
