Houston...I think you have a problem...maybe it's just me but I don't think that's suppose to happen. Can you imagine the force on the hinges? I'd check and recheck the hood/hinges and how things line up. The air should flow over the hood, not under...and excess air in the engine compartment should flow out the side vents...maybe those goofy silver things on the side vets are blocking the air flow from exiting; or is that a reflection? 158 MPH, impressive but this car was engineered to do in the 170's. I'm sure M/T, Road and Track would've shown us all a picture like this had their test drive resulted like this.

I wouldn't be surprised if all Z06s didn't do that at high speeds. The Z16 with the CF hood which is very flexible is probably a little more sensitive to air rushing in through the front screens, over the radiator shroud and hitting the bottom of the hood before exiting from the side vents. This creates a lot of underhood pressure which is combined with the overhood low pressure zone to force the hood up.

Mine does this too, pretty badly at high speed. It has been so bad on mine that I have considered installing external hood pins to keep it in place - cause it's damn scary sometimes cruising down the highway with the hood lifting off...
I was told by somebody that it's common the Z06's cause they allow too much air under the hood with the cut-outs up front and it creates a pressure zone under the front of the car.
I can't beleive this isn't a more common concern...
