If Jim Mero has truly done a 2:50 - 2:51 at VIR

I have respect for the guys who track cars on these road courses as they are likely far better drivers than I am. The track times being discussed here for late model Vettes as well as guestimates on the C7 seem to be in about a 5 second range for a lap that requires just under 3 minutes to complete. Are these differences significant? Will anyone will feel a difference on the street between a car that runs a 2:51 and another that turns a 2:55? I am not being facetious as I really don't know and am interested. I know that a car that runs 11 flat vs one that turns 12 flat on a dragstrip is a profoundly different experience when street driven in most cases.
A car that is 5 seconds faster on a 3 minute road course is notably faster. After a couple of laps, the trailing car wouldn't even be in your rear view mirror at all.
In daily driving I don't expect you would feel a huge difference though. In very spirited street driving (aka illegal driving
) you would IMO. Remember, track times are more than just pure HP/torque. You are more likely to "feel" increases in HP/torque on the street than you are to feel all of the components of the car working better together in a way that materially improves lap times on a road course... braking, suspension, chassis stiffness, power, etc...

It looks like our VIR lap time projections came true from a year ago. There were many on this thread that would not believe the Stingray would do a 2:53 at VIR.

Yes, that has shown to be good for ~2 sec on the Full course, which is the majority of the Grand Course. So to compare it to the previous times it would be closer to a 2:55. But the other factor is, did they really get their beat lap before the engine let go?

I was at Laguna Seca when Motor Trend and Randy Pobst had the Corvette C7, Ferrari F12, and Porsche 911S test. I saw Pobst drive the C7 within 2 tenths of a second of the F12.The Corvette engineers were there that day and they downloaded the latest suspension specs to the display car that they were testing. They ran the C7 again and matched the F12 time. I'm not sure if it was Pobst driving or the Corvette engineers driving it, but I heard somebody yell out the time that was hand timed. Somebody asked if they wanted to use the new time. One of the other editors said no as it didn't have the timing equipment hooked up. They were totally fair and accurate with their protocol. Regardless, how can the F12 be 3 seconds faster around VIR when the Laguna Seca results show a closer gap?? I think the Motor Trend test with a pro driver (Pobst) might be more accurate. The Motor Trend test will be out shortly as well. I believe they did the Best Drivers Car Test in early June at Laguna. Both the C7 and the Z28 will be in that test so we can compare then.

Now I know everything.
And just for the sake of arguing..what about a Z06 that doesn't have MPSC equipped?
