What everyone missed about the 2023 Corvette ZO6 LT6 reveal

The LT6 is the newest engine in GM's lineup. Even though it's called an LT6, it shares nothing with it's "LT" family. There's a lot to learn and feel free to pause the video to view any details that I left on frame because I don't want to bore to death with technical numbers and calculations. What a refreshing site to see at a time when everything is going electric or turbos. At this point in time, this is one is going in my all time best list.

It's the same as anyone they gave up low end tq for high end hp. Also they are using a expensive low production engine not based on other stuff they produce. But hey gm already said they lose money on each c8 that's why they are so limited in production. But they miss the mark for consumers. What would you rather have a 850hp 850tq engine that makes power all over or a high strung n/a motor that also vibrates much much more and sucks to drive anywhere besides a race track and still with all the drawbacks gets killed by a car that's available and cost 50% less. Boost is God and when people are making 1500hp and 950ft lbs out of 2.0 motors well we know that the c8 already had heat issues adding a turbo was probably not a option because with 5psi the stock base c8 would kill this 50k more expensive car

Very interesting and more about the engine than I had seen before. Interesting that they use a flat plain crank right after Ford drops theirs. Finger cam followers; I hope they work out better than they did in Chevy's 2003 Indy engine because I had heard that was the reason that went flop! (They started using an engine they bought from Cosworth mid season in 2003). It was also frustrating that very little of the accessory end of the engine was shown. It would have been nice to have seen how the cam drive and other accessory were arranged compared to the LT-2. Belt or chain, turning four cams takes much more than turning one and gets messy fast if not given proper attention!

[@jonathansmith4968]

@@frank.l181 yes, but with 2 valves, you can't breathe that high anyway, so you couldn't use a "high RPM" valvetrain anyway. Basically 2 designs approaches: 1) High RPM, lower torque (not as much stroke to keep piston velocities manageable) - over square - larger, heavier engine (DOHC takes up lot of space) 2) Lower RPM more torque under-square (more stroke) smaller overall foot print. Neither of these are a "perfect" solution, each has a trade off. Just like flat plane vs cross plane: Flat-plane - lighter, faster revving, more power (due to better exhaust savaging) - perfect 1st order balance, CANNOT be balanced on 2nd-order vibrations. Cross-plane - Heavier (counter weights), lower revving (can be used with longer stoke for more torque) - perfect 1st order AND 2nd-order balance. Everything is a trade off.

With those dual throttle bodies, it seems very suited to a twin turbo set up. Maybe they designed it with that in mind, perhaps thinking ahead for the zr1 🤔

I can see a big difference in that single to twin intake and what ever those 3 valve's in the middle still mean, I'm still working on that, I'm 63 yrs, and I can understand the older models of the carburetor center mounted intake, that's the old way of referring to the old self-induced aspirated intake, if I'm guessing this right, aspiration still means vacuum suction, and vacuuming the air flow of the heads of the valve's, and through this engineering numbers are boosting higher numbers of hp, plus the way the fuel injection systems are being sharpened up, so I'm getting at is the fuel injection is getting better, aspiration means natural vaccum circulation, no turbo or supercharged system of either kind, but you still need to figure out how much hp your going after,

I'm split here: I understand that DOHC engines have higher rpm speeds and can get up to speed quickly, BUT and this is a big one: the sound. If the LT-6 had a throatier snarl to it and not sound like a Ferrari knock off, I would be fine. The thing is that OHV small block has the traditional thunder associated with the Corvette, and as fast as this ZO6 is, it just lacks the thunder of a small block. I would have been happy if the powers that be GM made a revised LS7 that had more compression and solved the valve dropping issues, because, yes it wouldn't spin to 8600 rpm, but the howl of a 427 ci engine running to 7000 and pulling the same speed would be awesome.

Finally something new worth buying

[@ditoalfrido]

very amazing character-body design. sf90, c8 z06, nsx 2nd-gen 😱all of them

[@CRUSHFACTORPC]

Might recheck your numbers because 480 TQ @ 7400 RPM is 676 Horsepower I think you got the HP and TQ numbers transposed.

[@tont3305]

With a flat-plane crank you get very little torque because they're such a short stroke and there's no counterweights

[@CRUSHFACTORPC]

@@tont3305 That actually has nothing to do with the post I presented.

[@tont3305]

@@CRUSHFACTORPC yes it actually does. The math that you have bid based on is on a standard motor. This is not a standard motor but whatever makes you happy

[@CRUSHFACTORPC]

@@tont3305 I don't care what motor it is even if electric HP ALWAYS = Torque X RPM/ 5252 PERIOD I don't care if it has an airplane flat plane crank. AT 7400 RPM with 480 TQ it will ALWAYS = 676 Horsepower. AND the earth is a sphere.

[@Sir_Cactus]

Anyone else noticed that when he talked about the crankshafts, he showed a normal flat plane crank without counterweights as an example what crank it does NOT have, and showed a picture of a technicly flat plane crank with abnormal design, that does require counterweights as clearly seen as an example for what crankshaft design it has, even though it has the normal crankshaft design. He even said the crankshaft in the LT6 does not have counterweights. The flat plane crank that he said it has but does not is actually a flat plane crank from a V8 by Ford, in which performance was sacrificed for sound.

[@reeseferrell2731]

[@appleiphone69]

Surprised and concerned that they did not add port injection as well to deal with carbon buildup on intake valves.

[@GTContent]

I assume it's because the "pressure" from the velocity stacks might take care of it 🤞

[@alexthai4957]

I'm a vette fan but the disturbing answer to your question in the title is.... What everyone missed is that my wife's daily driver Tesla Plaid will leave the 2023 Z06 LT6 in the dust. All the rocket logos can't compete on the street with Tesla's 1000+ HP and instant torque in stock trim. Like you said, it's in a league of its own.

[@Gchang54]

That's the only thing it has on it, just power, the z06 will be better everywhere else.

[@alexthai4957]

@@Gchang54 I agree completely, The Irony is that many people make the investment in LT6 to be king of the street. They want a powerful car. The Plaid happens to excel in that department and humiliates the vette in acceleration, the one thing sports car enthusiasts crave.

@@thedaredevil1907 there no known reliable FPC engines period. The fact tbey are using a proven to be unreliable valve train design says it all.

[@DavidNJ1]

Where would you use this car? It would be at the speed limit in seconds (attracting police as it got there) and is sufficiently wide that staying in your lane in country roads is a challenge, in contrast with apexing turns. Race track? Any car with this speed potential (my guess is it would hit 150+ on post tracks) would need a full cage, containment seat, and HANS device. That would render the car undrivable on the street/ Is it really more for show than go?

[@siamean1]

WOW!! The Pontiac Fiero finally reached its full potential, by disguising itself as a Chevy to sneak pass the bean counting execs at GM.

[@markdupre4854]

Very nice video, well research and presented, nice job, I feel smarter now!!

[@Flies2FLL]

The pictures at 5:04 are incorrect. I think the upper crankshaft is actually a typical flat plane crankshaft, whereas the bottom picture looks like the crank in the Ford "Voodoo" engine.

[@natez0690]

Yep, at 5:04. Two different versions of a flat plane crank. I know it’s a confusing concept and that’s why we aren’t all engineers.

[@antonioovalle7985]

[@pophamlarry]

Ford Pantera back in 1971 built a mid engined car with a Ford 427 cubic inch engine.... now that was a beast....😁

[@craigthescott5074]

That car had a 351 Cleveland engine I believe not a 427 and Pantera was not Ford they just used a Ford engine.

[@mbukukanyau]

It’s not one of the most.. it’s the most

[@kledomuc1713]

Thanks for the great HQ vid. I wonder how the fuel is mixed up efficiently at high rpm and high load hence there is no time. This is a known problem, that’s why some engines are built with combined injection systems to join advantages of both worlds. Cosworth still uses port injection in their V12 engines.

[@GTContent]

Maybe the ability to "build pressure" via the velocity stacks helps.

[@wernerdanler2742]

@GT Content Porsche had velocity stacks in the 996 I believe it was. They were vacume adjustable.

[@Stars-and-Stripes-]

I think the new ZR1 will possibly use this same engine, but augmented with an electric motor or 2 up front for AWD and say an extra 150-200+hp and have instant low end torque that this engine is lacking due to it's lovely high RPM nature.... Think about it, it would have 8-900+hp and tons of torque from idle on up to redline! They could just go with a supercharger which would be great, But why when you can get even more benefits from electric motor's.... To be honest I would be completely content with the standard 670hp Z06, as it has more than enough power, but for those that need the ultimate "budget" Hypercar , there would be the ZR1... Hopefully GM would price it below 150k and have a car that will run with the $300k and up exotics for a lot less $$$ They would really put it to the others if they sold it for say $125,000... I love that GM finally decided to go with a mid engine dual over head cam setup, Not only that ,but they managed to make it the highest HP per cubic inch production NA motor of all time! I think that GM has finally built a great Corvette , I think Zora Arkus-Duntov would be so proud of what they did with the C8 ZO6....I just wish that I could actually afford something even remotely close to this price range! I guess I just have to stick with things like my old home built V8 Mazda RX7 budget sports car....

[@Wesley3129]

I've heard rumors of a dual turbo setup but who knows.

[@TheDiamonddust1]

@@Wesley3129 What gets over looked is the natural aspirated horse power these engines are producing without any power adders bolted on them yet when you consider ford and dodge engines . We then can add a turbo or supercharger to these set ups and see something that will run with most anything on the street or travel faster then most care to or want to in most cases .

[@farangatang]

Z06: 5.5L NA ZR1: 5.5L TT ZORA: 5.5L TT + dual electric motors We've know this for over a year 😉

[@trobertson1825]

This is a track car and those are the people who should purchase it

[@elchido3517]

Possible the C8 ZR1 will be TT, it will keep the current intake like C8 Z06, this because if it be supercharged, they have to remove that new design intake manifold, and i don't this will be happening, but if the new ZR1 C8 is TT, possibly be around 835hp just guessing.

[@markball7028]

Root style superchargers are generally inefficient and create a lot of heat at high rpm’s. Because of the high rpm characteristics of this engine it will never see a supercharger like the previous generation pushrod engines. A centrifugal supercharger would work but packaging and belt slipping raise issues. Turbocharging will be the most effective and efficient way to boost this engine. But we may never see a boosted version of this engine at all. With EVs being pushed hard these days I see a hybrid version being the the new ZR1.

[@marcdargitz2949]

Regarding a ZR1 possible having AWD and 800HP; personally for ideal sports car handling characteristics, I'd consider the new C8 mid engine platform ideal for launchings..no AWD needed. When you start introducing more weight and complexity of AWD,, you compromise the goal of nimbleness(overall sports car feel)... regardless of power to weight, weight can't escape gravity! Also, adding a supercharger will certainly make it a powerhouse, but once again the NA offers plenty for daily driving, while not introducing added stress, weight, and complexity to the overall dynamics of the car.. something to consider, in my humble opinion.

[@PartStupid]

A chevy engineer said they gave the Z06 a shorter gear ratio in one of the videos I watched. It is gonna pull hard that is for sure. My father got a 2022 Z51 and that this already is nuts so I cannot imagine this new Z06.
