How much more hp would be needed to achieve 200 mph?
What mods would be needed to keep it NA?
I've always wanted to drive a Corvette at 200 mph. I would take it down to the Texas 200 or similar place for a safe run. My partner has an A8 Audi that we drove 265km (165 mph) regularly on the autobahn, fastest at 285km (175 mph).

I have had my C6 over 170 many times in Rural Eastern NC....but not my C7. Since moving to FL I have yet found someplace where I can safely open it up. Anyway, I've come to the conclusion it isn't the top speed that counts it's HOW you get there that matters.

What is the point? I mean unless you have a compulsion to test the car to the max like on salt flats what doe it matter. Absent a track much over 90 is approaching un safe not because of Corvette but because of other cars animals etc. on the road you have no control over. Corvette is fast enough. I was on the turn pike the other day paying more attention to the radio than the car speed. Felt like I was running 30 mph but more like 85 and it got there quickly. C7 top in is faster than most people will want to go.
Secondly there's no much in the way of cars or animals when you're driving in Death Valley. You can easily do say 130 MPH... Not that I've ever done that officer...

GM advertised the C6 Z06 at 199 mph in 5th gear. However, it took a very long time to get there. It doesn't take much time to get to 160 but from there on up the acceleration slows. I hit 158 a few times at the end of straights in my C6Z.
Not sure how fast the C7 will be but the base with Z51 will probably have a higher top end than the C7Z due to not having the aero pieces on it and having a narrower body.

C6 GS A6 would need around 455 whp (67 whp) above stock
C6 Z06 M6 would need around 600 whp (154 whp) above stock.
Now to hit 200 in a mile event...
C6 Z06 M6 would need around 703 whp or 257 whp above stock to achieve 200 within a mile.

Short of the VW testing facility in Germany there really isn't a safe place to hit 200 MPH +.

I bolded the part it doesn't meet. Animal or some sort of debris coming out onto the road on that stretch of road at speed and yeah....

Oh, and as it has been pointed out here - your vette ain't gonna be doing 200+ MPH anyway. Basically all of your "points" have been negated but something tells me you'll argue nonetheless...

My C6 Z06 had (Y) rated Goodyears and it's top speed, right out of the factory is 198 MPH and the ZR1 had (Y) rated Michelins and it's top speed, right out of the factory is 205 MPH.
All C7's have the same (Y) rated tires as did all C6's(including the base C6 with it's 190 MPH top speed right out of the factory).
There is a difference between Y rated tires and (Y) rated tires. You need to educate yourself.

So bench racing math says... (using c6 numbers cuz I have em handy). To achieve 200 top speed stock drivetrain, (not limited to 1 mile event)
C6 GS A6 would need around 455 whp (67 whp) above stock
C6 Z06 M6 would need around 600 whp (154 whp) above stock.
Now to hit 200 in a mile event...
C6 Z06 M6 would need around 703 whp or 257 whp above stock to achieve 200 within a mile.

If the C6 Z06 had the .82:1 5th gear, where it was delivering 82% of the engine's torque to the pinion gear(like the C7 Z06), then it would hit it's top speed of 198 at 7,000 RPM.
The C6 Z06 would have the same top speed, but it would accelerate quicker from 162 to 198, with the .82:1 5th gear ratio.

As for hitting 200MPH...I'm sure my boosted C6 will get there no issue.
