Just read a few minutes ago on Midenginecorvetteforum that the Z06 will have 600 hp and go to 8500 rpms. Starting at $85K no options.

I don't care what they decide on...
based on my experience in my 19 zo6...
this car will eventually be a world beater...
and I'm gonna buy one...
and guessing tons and tons of mid engine folks and usa proud folks will too...
buckle up and congratulations to chevy for having the ***** to build it.

So one can "assume" that a decently optioned 2022 Z06 will MSRP at $110,000 ??????

I’m thinking that. Maybe more.

600 HP is a believable number. Im going to guess if thats the number we get then they have managed to take some weight off the car. No way it will only be 600hp and weigh 200 pounds more then the base car that just doesn't make any since. This car will be faster then the 650hp c7 z06 just wait and see.

the C7 Z06 is having trouble with the stock C8. I’m believing the C8 Z06 should handle all old stock Z06’s. We shall see

Engineering a lightweight platform hasn't happened since the days of Dave Hill - if the intent is a 600hp N/A motor, IMO the weight needs to come in at sub 3250, which I don't see happening, not even close.

Personally I think the FPC is something of a gimmick on the street at this point. Revs can be generated without it using DOHC's and generally the harmonics of FPC setups don't tend to help long term longevity of engines. Ferrari's rarely make 100,000 miles without and engine rebuild. Hell, I'd bet less than 10% of FPC engines see more than 60,000 miles during their lifespan. If you buying a car to race that spends a great deal of time on the trailer it doesn't really matter. Likewise a street car that seeing largely low rpm usage also likely sees less failures.

I'd say that Ford's recent experiences with failed FPC engines is worth considering. I actually did consider cashing in on my C8's value to move to a C8Z, but I'm happy with my car and honestly there's almost no instance where even the base car's full potential can be seen on the street so it's really a moot point for me.

It only needs to go FPC for the C8R's IMSA eligibility. 600 hp seems low when you can get that out of a heads/cam LT2, probably.

You do realize this has a throttle plate for each cylinder, and an exhaust header with pipes crossing from bank to bank.

Can you point to a single cam-in-block engine produced today that revs to 8,500 RPMs and delivers 600 HP meeting emissions and is naturally asperated ?]

Not even for that. DOHC, yes. FPC, no.

Pretty sure that's why he posted it.

what trouble is that? 0-60 mph? Or against a bad manual driver? That's about the only time a c8z51 beats a c7z. Remember the numbers:

c8 Z51: 3650 lbs, 500 hp
c7 Z06: 3550 lbs, 650 hp
​​​​With full tanks of gas.

On a race track there's quite a bit between the two.

I expect the c8 Z06 to have 680 hp and weight 3750 lbs.

One of the benefits of a FPC V8 is even exhaust pulses on each cylinder bank. This enables faster and more efficient turbo spool and twin scroll turbos. And with turbos the displacement can be kept low enough to minimize NVH.

I don't think the intake matters, but the C8's a mid engine car - so why would the header primaries crossing over be an issue?

For a custom, hand-built race car? No issue. From a manufacturing/assembly/maintenance perspective? Nope, uh uh, not happenin'!

Seems like a better solution than an engine that wears out after 30,000 miles.

Well, you and I are in agreement that a FPC isn't really desirable for a street application. Heck, I'm an old pushrod guy (still think it's a better package for the street than a OHC), but I'll accede to TPTB on that change. At least reliability should be on a par with a cam-in-block (hate the OHV label, like an OHC doesn't have overhead valves) configuration.

Have a good one,
Mike

Well, maybe the Z06 is going to be a limited production, full on factory race car, like the old C3 ZR1s.
