C8 Z06 Power Train Toss Up: NA for Z06, Turbo for ZR1

I thought this article regarding power trains is VERY interesting. It states that Z06 is getting a 600 hp N/A power plant, where as the ZR1 is getting the Twin Turbo we keep hearing about. Do you all think that the C8 Z06 in this platform would then overtake the current Z06 in performance on the drag strip-1/2 mile? Current C7 Z06 mph seems to range from 127-131 depending on weather/tires/prep. I for one, don't overly care about type of power source (NA, Turbo, etc) I just want it to pull on a hellcat haha.

I'm debating ordering a C8 after the house is built this coming spring or waiting for this Z06...sucks waiting.

I will be shocked if the C8 ZO6 has less hp than the C7 ZO6. What I suspect is that the ZO6 will be twin turbo DOHC V8 but there will be another NA V8 version introduced below it. This 600hp NA V8 may either be a new base engine to be introduced once initial demand subsides, or it could be a tweener engine for a track-focused Grand Sport.

Tadge is on record saying his dream engine would be an oversquare extremely high revving NA V8, so I lean towards the Grand Sport engine theory. It's probably the NA version of the twin turbo DOHC V8.

Interesting inside info from Car and Driver, May 2018:

That engine bay will also eventually host even more compelling mills. The first to follow the LT1 will be a naturally aspirated 5.5-liter DOHC V-8 with a flat-plane crankshaft capable of a Ferrari 458–like maximum engine speed of 9000 rpm. Sympathy for the transaxle, though, means the engine speed will be limited to several hundred rpm below that. That engine should be good for at least 600 horsepower.

In the same article, they nailed the LT2 base engine, so they definitely have a source:

To contain costs, Chevy will launch the new car with an updated version of the pushrod LT1 engine that powers today’s C7 Corvettes. We expect the mid-engined Corvette, or C8, to be a bit heavier than the current car’s roughly 3500 pounds, but it will compensate for that with about 500 horsepower from the LT1.

And the same article predicts that the same NA DOHC engine will feature a brace of turbos for an even higher output version:

Then, because it is totally unnecessary, Chevy will bolt two turbochargers and two big air-to-water intercoolers to the 5.5-liter V-8. The turbo engine will make about 800 owner-maiming horsepower.

It's almost like the source for the Muscle Heads and Trucks article was an old issue of C&D!

Hmm, a 600HP small-block NA engine... Possible to achieve, of course, through displacement/heads/cam/FPC, but I do wonder how "streetable" that engine would be, and fuel economy would probably remind us of the 60's muscle cars.

I don't see it happening.

The supercharged LT5 is a better option for the C8 Z06, IMHO.

Leave the twin-turbo for the C8 ZR-1, and the twin-turbo with electric front wheel drive for the Zora.

Do not forget there is a reason for that boxed in frame spine in middle to store batteries
So who knows which model gets front driven electric and adds 400-500 more peak HP with the existing LT2

If they dropped in an LT5 would anyone complain? Other than FLAT PLANE DREAMERS?

It can’t meet the 2022 emissions so that’s why we’re going to see a smaller displacement turbo engine.

Where does one find that information?

I think you are probably right on your over all expectation. Lot of possibilities but this "post" is most supported and probable.
