FPC is about making more power from NA. Higher RPM's equals more power. Exhaust scavenging on cross-plane runs into a wall at higher RPM. DOHC and FPC fix that. Additionally full VVT on intake and exhaust plus VARIABLE LIFT is like having a BIG CAM when you need it and driveability at low RPM. Net result is very nice experience, a snappy throttle broad torque curve in the RPMS of interest.
Additionally, I suspect that all the Mid-engine, DOHC, VVT, FPC, and DCT will combine make it faster. 911 GT3 previous gen and current gen are faster than Z06 and have lower power to weight. I am not worried.
Lastly, the C7Z was fast for 1 -2 laps. NA will be faster, longer. Have faith that GM's plan isn't to suck more.

Man, it looks like my dream is actually going to come true!!!!!

1: That it makes sense for the C8Z to be NA.
2: And if NA, @ 600-625hp will be more than enough, and will be "faster" than a C7Z.
3: The C8Z "should" be the track car of the C8 lineup. And the ZR1 "should" be the street monster/track car (something the C7Z was but couldn't do track duty efficiently).
4: C8Z will start at 95k (although not proven yet, i still think this is the case).
And lastly, it's starting to come to reality my hopes for NA goodness. I know nothing is confirmed yet but i have confidence this is going to actually happen.
I'll save my true celebration for later

The ZLE doesn’t over heat because it has plenty of frontal area for cooling and I consider it a middle weight these days, it still consumes more fuel/brakes/tires than a lighter car of similar power to weight. If two cars have the same power to weight and all else being equal the lighter car will be faster through the corners just like the ZLE is compared to the heavyweight GT500 on similar tires. Just got done instructing/driving GT350 today on Cup2s, it’s so effortless to put down power with the low torque of the FPC. It’s geared taller than the SS1LE as well, they’re both in the same class for SCCA Time Trials and agree they’re equally matched along with my C6GS. The LT1 makes the best average power of the three, better than the Voodoo or my LS3 imho.
I'll add to your power to weight comment though that the heavier car with the same power to weight as the light car likely has a lot more power to fight drag at the end of the long straights. GT500 for example has some crazy speeds on those straights. Tires and brakes do wear fast though.
That's very helpful insight about those three cars.

My GT350R was ~3650lbs so 200lbs lighter and you can feel it. I put it on bring a trailer and it sold. I regretted it instantly. C8Z FPC would be a monster. I still want a GT350R, C8Z FPC, and a 992 GT3 to have all the flat-planes. One garage to rule them all.

That 350R has a cult following for a reason

Let's just hope my predictions are really true. So far it's looking that way!!!

The zle, ctsv v3, and the zr1 all have no limp mode issues on the track. The z06 had some issues on certain tracks in extreme heat with the auto mostly due the frontal area not bringing in enough air. That’s why they redesigned it for the zr1. I get it it had some issues for some people but not everyone. The guys at spring mountain had a fleet running for years in the 100 + degree desert heat. So there’s that.

My 2015 A8 when stock, first time with it at VIR it overheated in about 3 laps and went into limp mode, leaving it in auto / 6500rpm shifts. It was a May day, high 70s low 80s temp. Switched to manual and limited it to 5000rpm, got a few more laps but not many, plus a huge power reduction when it wasn't limping . I know how the engineering team must feel about this, no matter what they may have said publicly or improved in later models, it's still a black eye, and this is why I believe the C8Z will be targeted to go above and beyond to have no issues in this area.

All good. The one I drove was a 16 M7, then drove a 17 same day and did not overheat. I don’t remember the numbers but I may have it on PDR. My 17 M7 did not overheat. The A8’s were more prone, the 15-16 in general was more prone than 17+. I’m not sure how the 19’s do with their upgrades.
