UNTHINKABLE: C8 ZR1 will have a SUPERCHARGED & TURBO Engine 

Twin charge would be wild

Very interesting speculation here! Would be awesome to see Chevy do something like this!! Great research!

Very well could be right. I also think an LT3 is coming, that's a dohc cpc V8.

Either way, great discussion!

I think you are correct…your theory is very well explained..So much more information than others 👏🏽👏🏽

You raise good points. It certainly would be "unthinkable" in many aspects

Well thought out, great research, seems probable to me!

I just ran the engine description through ChatGPT with this results: User LT7-ENGINE GAS, 8CYL, 5.5L, DI, VVT, AFM, SC TURBO, DOHC ChatGPT It seems like you're referring to a specific type of engine specification. Let me break down what each of these abbreviations typically stands for: LT7: This seems to be a designation for a particular engine model or series. ENGINE GAS: Indicates that it's a gasoline-powered engine. 8CYL: Indicates that it's an 8-cylinder engine. 5.5L: Refers to the engine displacement, which is 5.5 liters. This is the volume swept by all the pistons inside the cylinders. DI: Stands for Direct Injection, which means fuel is directly injected into the combustion chamber. VVT: Stands for Variable Valve Timing, a technology that adjusts the timing of the opening and closing of the engine's valves for better performance and efficiency. AFM: Stands for Active Fuel Management, also known as cylinder deactivation. This system allows the engine to deactivate some cylinders under light load conditions to improve fuel efficiency. SC TURBO: Indicates that it's both supercharged (SC) and turbocharged (TURBO). This is somewhat unusual, as supercharging and turbocharging achieve similar goals (increasing engine power) through different means. It's possible this is a theoretical or conceptual designation rather than a common engine configuration. DOHC: Stands for Dual Overhead Camshaft, indicating that the engine has two camshafts per cylinder bank, one to operate the intake valves and one for the exhaust valves. Combining all these features, you have a high-performance, gasoline-powered engine with a large displacement, direct injection, variable valve timing, cylinder deactivation for improved fuel efficiency, both supercharged and turbocharged, and featuring dual overhead camshafts for efficient valve operation.

Here is what is going to be, The Z06 engine but cross plane crank instead of flat plane crank and twin turbo. I bet you 1 taco.

Thank you for your time. I’d hate to think someone would criticize you for your opinion. Keep up the good work.

I think you’re onto something but I think this tech my be reserved for the Zora. It’ll already be a performance hybrid

Brother, great video, great investigative reporting! I think you may be on to something Clayton! 😊💪

I think GM spent to much time, effort and $$ on the flat plane crank to not use it in the ZR1? Maybe a new version DOHC non flat plane? But on the other hand I see the reasoning why they would not use this platform? Hopefully we find out soon. 4:44

I think you’re right!

I think it’s a very good possibility and a great concept for why to have both

this is a really interesting take, could be amazing if it comes

I think you are onto to something. I think you are spot on 5.5 with sc and turbo. The sound says so. It's also Tadge's legacy, it's going to be a wild machine. GM has the technology to do this. Other super cars will have old school tech!

Makes a whole Lotta sense, but I just don’t know - thanks for the info

Wow. Really interesting (and different) perspective and direction than what has been speculated by most. I do believe that something has to give with regard to how to manage the increase in horsepower, and your theory helps explain some of that. Like you, I am (hopefully) in a pretty good position for one from the dealer I got both my C8 Stingray and C8 Z06 from, but there are still many questions as to allocations and pricing. If this turns out to be anything like you described, we are all in for a wild ride…literally and figuratively. Great video and content, and now I am a subscriber. Thanks.

"The unthinkable coming..." I'm pretty skeptical of most projections but I like your thinking. Unthinkable would be something unusual, out of the ordinary. Both supercharged AND turbocharged would certainly fall into that category and your reasoning on it's aid to performance makes sense. DOHC crossplane is what I expect and would bet on it. 5.5L turboed flat plane is so unlikely...all the big boys seem to top out at 4L for turboed flat planes. I really don't see GM dropping cubic inches. I recall a comment from GM that the ZR1 would have substantial HP. That tells me maybe around 850 or more. A special induction system just might easily bring that.

great investigation. 1017

Interesting 🧐

Good thinking and research. What ever they use will be on another level. I just hope it is not $200k plus.

If you are right this will be absolutely crazy

I suppose anything is possible, with such crazy advancements, in current technology. But don't forget, even if it is the flat plane-crank, with a twin turbo setup; it will no longer sound like a flat planet crankshaft engine. Because, Turbo's muffle the exhaust sound.

Since they put a lot of money and R&D into the 5.5L I am sure they will use this for the ZR1 and Zora, they are in the super car realm..

No no no. The Zora is still coming, Zora. That part can be used for the supercgarged ZR1 or turbochaeged ZORA

AWESOME video! This is the first video I've seen from you, and you earned my sub even if you're wrong. There is a very strong case for your speculation, and I never put that together before now. When I saw the video pop up in my feed, I got a rush of excitement at the prospect of this being a possibility. I won't lie. At first, I thought it was just a bs clickbait video like so many others. However, after hearing your argument paired with the evidence you showed, I'm with you. I think this may actually be the real deal. I congratulate you on being the first one to bring this to light. When I watched the ZR1 teaser, I was stumped at the word "unthinkable" as well. I thought to myself, "What could THAT mean?". This would explain it! I couldn't be more excited for this car... GM is always surprising everyone with Corvette. Great work! 🔥🔥🔥

5.5 Cross plane with SC and TT = 900hp and no turbo lag

It would be amazing to see an actual SC on a twin turbo engine. Someone did it to a hellcat a few years ago for a giveaway .

An interesting take on the unthinkable. Some might be concerned if it is true, would the “high maintenance” be worth it to the typical customer? Ya, it would be worth it! 😂😂😂

Supercharged at low RPM and big turbocharged at 4000 RPM.

Supercharged E-Ray & Paragon are there with some cool Cars :)

I would think the engine would be 5.5 cross-plane crank with twins. I would think GM might use some sort of electric motor to spin turbos earlier and disengage once turbos are at full boost on their own. Would save a lot weight. The patton is definitely a 4 banger engine. Compound boost is cool, but expensive to implement and maintain. It would be wild though.

Makes sense to do an eAWD.. especially with an electric supercharger.

imagine that

I am personally hoping for a CPC engine to boost reliability over a FPC regardless of what type(s) of induction system Corvette engineering decides to use!!! The exhaust sounds of the supposed ZR1's at the Nurburgring Nordschleife testing & the ZR1 teaser video suggest a non FPC type design. Thanks for your sharp eyes and investigative mind!!!! "COME ON ZR1"

I just asked ChatGPT : best guess as to the LT7 being a FPC or CPC & here bis its response: Based on current trends in automotive engineering and considering the potential performance goals of the LT7 engine, it's reasonable to speculate that it could be a CPC (Conventional Pushrod Cam-in-Block) engine rather than an FPC (Flat-Plane Crankshaft) engine. CPC engines, with their traditional overhead valve design and pushrod architecture, are often favored in applications where high torque and low-end grunt are priorities, which are characteristics often desired in high-performance American V8 engines like those found in the Corvette lineup. Additionally, the CPC design typically results in a more compact engine package, which can be advantageous for packaging within the Corvette's tight engine bay. While FPC engines are known for their high-revving capabilities and potential for higher peak power output, they often sacrifice low-end torque, which might not align with the performance goals of a high-performance Corvette model like the ZR1. However, this is still speculative, and the actual configuration of the LT7 engine will depend on various factors including GM's design goals, engineering decisions, and performance targets for the ZR1. Only official announcements from General Motors can confirm the engine's configuration definitively.

TT Crossplane 5.5L.

I mentioned that i would spend money on a twin charged zr1 . But i also added that it should be hybrid as well. 1290 hp would be nice.

Very interesting except we have all seen Nurburgring testing videos that simply dont have the supercharger whine. The other problem is GM has so many engine patents FOR MILITARY APPLICATION, and thats what it sounds like. More than likely you only have to look back at Cadillacs original BLACKWING engine which has between cam turbos like AMG GTR setup. All that GM would have to do is configure that engine in larger displacement and oversquare. GM has so many options that whatever it is will be one of the best engines the world has ever seen Guaranteed.

I like the way you think. But if they did "twin charged" what does that leave for the Zora model, Quadro-twin- double charged? 😂

Legit video. I think you could be on to something here... Using a power source "similar" to the E-Ray driving a supercharger at low rpm's handing off to turbos?? Or something different😂

The C8 Z06 has a level of supercharging in its intake system. Small but, it does .

Turbos muffle the engines a lot. Even a flat crank v8 would be a lot quieter. Would be a crazy set up if they do both . Would be nice to get the e-ray awd system with the lt7 been a TT engine .

I clicked on this video expecting to hear BS but hoping it actually delivered some hope and now after watching it I’m damn near convinced you’re right about it being twin charged

Oh man with tons of respect you are not quite right on the ZR1. Today 4/29/2004 I was on the phone with Walt Masko who does a lot of 90+% of the test driving for the Corvette and Black Wing Cars. Basically, I could tell you a whole bunch, but let’s stick to what the ZR1 will be. The ZR1 will be a flat plane crank with twin turbos. HOWEVER, you were not entirely wrong. GM had 3 engines that they put through some massive testing and them trying to figure out the best engine is the going to be a flat plane crank with a twin turbos. I am betting you were hearing the base model corvette engine punched out with an added 15 pounds of boost. This was a very close engine that almost made it into the car as the flat plane crank engine was actually starving for oil when and if you ran it wide open for a period of ten plus miles. Today, though the talk was the ZORA. We were talking about how to get the car from 4,000 to 3,600lbs. That is a big issue with GM as in COVID GM decided to cancel their order for the materials that make up their carbon fiber. So, like the Z06 that I have, one of 13 allocations given out. The ZORA will be a very rare car that will be made. GM is not going to make a car that the customer can cheap out when it comes to the ZORA and its power. For example, all ZORS cars that will be made will come with all the aerodynamics and the customer will pay for it. That goes for most of the car inside too. Carbon fiber and if you cannot afford it then, it is what it is. GM/Corvette is already saying 0-60 in 1.9 seconds, after today’s talk, look for that number to be 1.75 seconds, 0-60.

I think it should ALSO have electric hybrid drive too!! To make it the COMPLETE monster!! All wheel drive like the eRay!!

It will be twin charge in the rear and electric in the front

Why not the Z06 FPC motor in Eray?

Twin turbo hybrid seems more likely. The hybrid system would eliminate the turbo lag.

It would be totally awesome but it should push about 1000hp plus I could be wrong but I don't think so

Finale? Combustion isnt going away. We already have seen the push for electric and the infrastructure isnt close to handling it. Even Elon has said this. Best would be hybrids. Supercharger for low end immediate grunt and turbo to kick in on the upper.

It’s all just guessing at this point. I think the “part listing” is bogus. I can’t believe they will have VVT and AFM with a SC and Turbos, can’t believe it. All the “leaks” are BS and designed to mislead, either by GM or others. If that is a real ZR1 sound, it’s not a flat plane crank. Does make sense that they’d SC OR TC a cross plane motor though, especially if they plan on bringing out a Zora; THAT may be a double boosted engine with electric motors or a boosted flat plane motor with turbos. Who knows? Guess we’ll find out. Keep up the guessing. Lol

Hope they can keep the temps down.

OK the C8 Z06 kicks almost "EVERYTHINGS" Ass to about 80 mph but runs out of umph the ZR1 with twin turbos and 180 more bhp / 390 more torque will never relinquish the lead that's a fact. And it will start with a even bigger lead then the Z06 given the ZR1 is supposed to run 0-60 in 2.1 seconds and the Z06 runs 2.6 give or take.

It should have more than 850 hp if that's the case???

Hate the lag on the Turbos......that's why I no longer have a Porsche......once you go supercharger it's a let down.

The Z06 sounds like a Ferrari the ZR1 sounds like a McLaren…

Its a vornado fan with twin turbos basically lol

"The unthinkable"....its a Coyote engine. Compound boost is inefficient, not unthinkable. (IMO) Edit- Ive ran turbos, blowers, and nitrous, as you speak on compression, the engine compression will be lower than N/A because of fuel availability. The customer base cant get 93 octane around the country, let alone E-85, my bet is itll be part electric. Sure, they patent some twin charged system, but they havent reinvented the wheel. They patented a design specific to their application of the item, to curb other manufacturers from taking the design and marketing from it. Who knows. Hopefully i remember this when its released and can find you again, im not into vettes, and have zero interest in them, I am curious. Thanks for making us think a bit.

Hell, why not just throw the e motor on the front too while we at!😅

Volvo s60 had that 10 years ago or so its been heard of already 😂

You might be on to something.

Sequential Compound turbo

So they are going the Volvo route 🤔 👀 😳 🙄

You compared a part naming convention to the engine naming convention lol youre reaching. I doubt twin charging because of the complexity of tuning that setup for a road car and reliability in all conditions. It would be cool though

SC STANDS FOR SPLIT COMPRESSION. IT'LL HAVE TWIN SCROLL/SPLIT COMPRESSION TURBOS. DUAL CHARGED WOULD BE WAAAY TOO MUCH HEAT AND COMPLEXITY ON AN ALREADY COMPLEX ENGINE. AND EVEN MORE WEIGHT ON AN ALREADY HEAVY CORVETTE. IT WILL HAVE TRACK OVERBOOST MODE THOUGH. LIKE 20 MINUTES WITH A FEW MORE LBS OF BOOST AND MORE COOLING SPRAYING THE INTERCOOLERS. AND ACTIVE AERO THROUGH THE FRONT DAM/HOOD, ESSENTIALLY A DOOR THAT OPENS AND CLOSES ACCORDINGLY

whatever they do please dont lock the ecus

Compound boost from manufacture…highly doubt it

I'm willing to bet large sums of money it is not twin charged

No way they do this with hybrid technology available . It will be a hybrid twin turbo 5.5 like the Ferrari SF90. A forced induction E RAY.

Grand National was an OLDS. With a TT v6 ..... Clue? ...... Reinforced version of the 5.5 block? For chrgd compression? That can be warranted? Exotic assassin?

5.5 tt

how about my really crazy idea..... 2 - 4 cyl Honda style engines ... 1 for front wheels and 1 for rear.. some of those crazy honda blocks w snails blow over 1000hp...don't reply and tell me how F'n crazy I am , I know already, I have a mirror & i live here.........lololol safe travels 2 all

Chevy is having to many issues with these c8’s I’m scared to buy one

Uh no it won't

Twin charging is nothing new (Lancia, Nissan, Volkswagen - Circa 1980.) On that basis "Unthinkable" becomes: thought, did, moved on.

HA, HA, HA... what a ridiculous Vid. I''ve had a CAD drawing of the ZR 1 Twin Turbo 5.5 V8 since 2019. This engine has been under development for longer than that.

I was thinking about what you said. I just did not want to be laughed at. Twin charged, with electric assistance and possibly diesel eng. could they put 2 small engines? Don’t laugh. 🫤
