Yes, the ZR1 is faster :)

It's truly refreshing to see good guys consistently share their talents for a better CF and doing so in style.
Thank you poor-sha!
So, good luck with the new toy and as you ready to tackle the track with all that hands on experience and comparative analysis (see videos) I wonder whether you sit down to do some track modeling math with telemetry data, curve exit speeds, and so on a priori to derive a feasible track time aim?
I just wonder whether Mero is doing the very same thing before he packs for Germany...
Cheers.

Wow! ZR1 is serious. I can’t even imagine how fast I would eat tires with 755 HP and downforce.

I want to address this comment that my post was designed to "stick my thumb in the eye of Z06 owners." I am a Z06 owner and have owned one since December 2014. In fact, I have been a staunch defender of the Z06 when the "Internet wisdom" was that it was a terrible track car because it was too heavy, was supercharged, couldn't be tracked in hot weather. I remember the gnashing of teeth about what a failure it was when it first came out because it lost a roll race to a Viper.
I spent much of the last 3+ years tracking the heck out of two Z06s and posting real data and my personal experiences to dispel the hysteria surrounding the Z06. I've run nearly 75 days and almost 150 hours on track in those two cars. In fact, I am a much better driver today than 3 years ago because I had something to prove about the capability of the C7 Z06.
Now here we are, the first couple ZR1 have hit the street and history is repeating itself. This forum is full of people complaining that it should've been faster in the 1/4 mile, or should've been faster in the mile. Neither of those are what this car was designed to do, this is designed to be the king of the hill on the road course and I wanted to post some very clear data of just how superior it is for the folks that don't think it's much of a difference. I have close to 4000 laps around VIR in a C7 Z06 and hitting 170 on the front straight is RIDICULOUS!
I am not saying that the folks hating on it are doing so because they wish they could buy a ZR1 but I'm also going to admit that I tried really hard to talk myself out of getting one as well (and the same was true of the Z06). In the end though, I wanted a chance to see what the ultimate front-engine Corvette, and possible the ultimate manual transmission Corvette can do.
I am truly blessed to have the means at this point in my life to take a $70K hit for that opportunity and I am going to take everyone along for that ride as best I can. I hope you all enjoy it.

going fast costs $ I'm just glad GM had the stones to up the ante on a very potent z06 Realistically this is just a bigger lion with more z06 goodness. The blower, cooling, downforce. continuation on a theme and although I'd like to have seen a dohc engine get the LT5 moniker, I'm OK with the hp and torq,
755 will get me from zero to jail quick enough

Reading through this thread, it's pretty obvious who actually has track experience and who sits in a lawn chair in front of their Corvette in a parking lot.
Thanks Poor-sha for posting those screen shots, it's pretty amazing the speed the ZR1 can carry in areas of VIR. I'll eagerly wait for your feedback once you get your hands on one.

The ZR1 lap was in an automatic right? By GM?
Does this mean that GM is advocating ZR1 automatics for the track or was this a hero lap?

The screenshots are misleading. 16mph 10mph etc at same points on the course don't tell the whole story.
if that were the case, would the ZR1 not be far quicker than the 2.5 seconds it actually is?
as your pics showed it was such a significant difference it forced me to go back and actually read what the difference was. And i was surprised at how little it was given the extra power and downforce. Hence my original post.

Yes, it's clearly an auto. I think they still recommend the manual for hard core track guys but the auto shouldn't have the same overheating issues, at least not the motor.

If you are keep up on your ironing duties at least weekly, the dust isn’t an issue.

My thoughts.. I think the auto transmission shifting faster than a manual is responsible for a large part of the difference in top speed. Look at the speed loss when the manual shifts from 4th to 5th. The shift time combined with the inefficient aero of the Z06 reduce speed dramatically during the shift. This doesn’t occur with the automatic ZR1, resulting in a higher top speed.
I am sure the aero was a big part of the improvement as well, not just is less drag but in being able to carry more speed on to the straight out of the last corner.

I think the auto helped but if you watch Jim in the manual Z06 he is no lift shifting so I don't think shift time is a factor. Of course, an auto also has more parasitic loss than a manual so there's that.

Yes, the aero is dramatically better. So is the power
Intake temps should stay down also. Just an amazing car overall!
Congratulations
