I wish GM would have supercharged the LT1 for the ZO6 and saved the FPC motor for the ZR1 twin turbo ZR1 package . Just my opinion but think it would make the ZO6 a better street version, with the higher gearing because of the lower revving engine, much better MPG with more torque, just seems like it would have made sense. A person can supercharge the LT1 but cannot get the kind of warranty with it that you could have if it was a factory piece .

No thanks. There’s enough motorboats on the road. I’m glad they made the Z06 special and it’s the only reason I’m still interested in the C8 platform.

So basically you want exactly what the C7 Z06 was... If that is route you prefer it is easy to achieve and substantially cheaper to just buy a normal C8 and throw a supercharger on it.

We have known for quite some time now that the Z06 was going to be NA and prior to that announcement there are literally hundreds of threads in this section debating what the Z06 "should" be....then numerous threads after the release on how GM has absolutely no idea what they are doing...how the car won't preform..its too heavy...its too expensive...it cannot beat cars that are 3 and 4X the cost etc.. etc...

Prior to the launch I was hoping the Z06 was going to be TT motor as I could not see how they were going to get above the previous Z06 performance by going NA. Then GM built what is arguable the best NA motor of all time (or at least an instant classic) and shocked the world. Now I am happy they went this route as the Z06 will be something that is truly unique (engine wise) to me that compares to the 90-95 Zr1's

On thing I know for absolute certain. Regardless of what they released there will always be people who are going to say they should have done it differently. Always.

Nah. First off, they don't even use the LT1. That left with the C7. C8 runs the LT2.

Considering this car has the LT6 and starts at the price it does, its a fantastic package. GM went the right direction with the Z06 this time for sure, as its more true to its past formula like the C5 and C6 Z06 but follows the C7's formula for added body styles (coupe and vert).

C7 Z06, if anything, was just a more attainable (aka cheaper) C6 ZR1.

I would have happily taken an LT4 with an unlocked ecm in the C8Z (priced at $20k less and available 2 years agp), but as I get older my desire to mod has greatly diminished. I'm happy with the LT6, I just hope it can go 100k+ miles problem free

This car isn't the car for someone who wants a supercharged car. That's ok, everyone wants something different, but this car's mission is much better met NA.

Some quotes from the R&T interview with Tadge.We went to naturally aspirated; Z06s have been naturally aspirated historically. We couldn't meet our performance targets with natural aspiration in a small block.

We had to supercharge it last time. Supercharging brings with it a bunch of mass, a bunch of challenges around keeping it cool. A bunch of challenges on making the car robust on track. So the last lap of the session could be as fast as the first lap and we think that's where this car really shines. I don't know if you guys found this, but in our testing it quite often is true that the fastest laps are near the end of a session just because the car's lighter and that more than offsets the tires going away. So it feels like a car that you can hammer on lap after lap, no excuses, no big deal. It always feels very much the same as it did on the first lap.
...

....
It's a dream come true. And honestly, when we started we thought "Well we'd be down on power, we'll be lower than 650 but we'll make up for it in everything else." And the customers really loved the LS7. There were some pretty loud voices that we shouldn't have gotten away from natural aspiration, but we really didn't have a choice back then. There was no way to do it. Now with the new architecture, we had a choice and credit to GM leadership at the time.
...

We don't talk the numbers very much and you didn't even hear us say anything about lap times. Even though the car is wicked fast on the track, it's all about the driving experience, whether track or the street. We're trying to get to the most exhilarating driving experience you can buy at any price in today's market.

Great thread. Would read again.

They made one of the best track weapons in the world that sounds amazing and broke power records and everyone wants it, yet people still complain....

LT6 is a masterpiece. Period. The C8 Z06 is what is it because of the LT6.

RedZ4me

so is the LS7 and then……..too many ka-booms

If you want a supercharged LT2 with a warranty, Callaway is an option.
The LT6 is an engineering accomplishment. The Corvette Team gets it. We are fortunate that this car exists. They just need to build more of them, NOW, before they introduce future variants.

JerriVette

Interesting thread. Many of us originally wanted a twin turbo lt2 yet we didn’t know the lt6 was possible. Lt6 hopefully isn’t the delay for producing and delivering z06 s to consumers

Factoid

I believe the LT5 is a much better engine than the LT6 in every category - power, longevity, flexibility, etc. Perhaps the LT6 wins in exhaust note, at least until it grenades. I admire GM for attempting to innovate but the old saying remains, there is no replacement for displacement. Now the eray is a whole different animal.

JABCAT

With 4 LT6 failures reported (that we know of) in the first few hundred delivered, anyone calling this engine a masterpiece or the best engine ever made really slurped up Chevy's koolaid this time.

Nitro-C5

Except for RPM....

Factoid

Yep, P=MV is a constant my brother!

Just like all the issues with the LS7 and LT4 making generalized statements is not being very accurate. I never bought into the LS7 or LT4 having massive widespread issues as I like to take a more holistic approach to data though if you were here on this forum when the these engines were introduced you would think those engines were complete POS by the hysteria being propagated. Just as with those engine issue I think the LT6 will be just fine during long term tests and giving long term data. Of course I could be wrong, but only time will tell.

Putting the potential engine issue debate on hold for a minute since we don't have any long term data yet. That said, to not at least recognize the accomplishment of what GM did with the LT6 is being a bit disingenuous IMO.

I think people don't understand that the Z06 isn't, and was never planned to be, the "top dog". They learned from the performance degradation of the C7 Z06 on the track that positive displacement forced induction is fine for the street but doesn't work as well under sustained loads. Its also one of the reasons why they are switching to ccvvt now.

Shokosugi

How many failures have been reported and how many Z06s have been made? What’s the failure rate based on that limited sample size? Without that information you are just projecting more of your C8Z06 bitterness.

4? Documentation? I've seen 2 confirmed, and a 3rd rumored.Out of about 900.

In any case, without knowing the causes it's simply too small a sample to reach any conclusions. But if there were a fundamental flaw, it seems unlikely GM would keep building cars they know they're likely to have to replace the engines in.
