The new ZO6 is absolutely nasty. I cannot recall a Supercar engine sounding this good since the Toyota LFA or Ferrari 458 which says a lot. I could only imagine how crazy the new C8 ZR1 is going to be. It’ll probably end up being an 800 plus Horse Power twin Turbo monster.
In the 90s GM would tell European automakers that pushrod technology had compact power. GM needed an engine that allowed a dropping hoodline, so drivers could see the road. Mid engine allows a dropping hoodline too, and also space for DOHC architecture.
@@KrustyKlown l agree, push rods and 2 valves per cylinder cause tremendous stress on valve train at high r.p.m use. Overhead cam 4 valve design is the way to go! 2022 Vette redlines around 9,500!
NHRA Top Fuel and Funny Car class. The quickest ICE cars in the world. Are all pushrod, 2 valve per cylinder. The architecture of the engine goes back to the 1950’s Chrysler Big Block V8.
@@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.
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!
This engine is based on C8.R race car, which race in ISMA racing series. Which race endurance races. The flat plane crank has proven to be reliable and powered the C8.R to back to back championships.
The photos of flat-plane and cross-plane crankshafts are wrong. The top photo is a flat-plane, not a cross-plane. The bottom photo appears to be a UDUD flat-plane crankshaft from a Ford Voodoo engine.
It’s already being done. The next version is supposed to be a all wheel drive with a electric motor in the front of the vehicle for the front wheels and I believe it’s called the eveo. Not sure how it is spelled. The next thing is going to be the Zoro all wheel drive and don’t know yet if it’s twin turbos or not but it’s rumored that it’s going to have around 1000 hp.

Great video! I love the 3D exploding animations of the various internals. Right at the 5 minute mark, you show an incorrect pic of the flat plane crank. You show the one for a Ford Voodoo engine. On the Corvette, and Ferraris, the two center pistons rise and fall together, not so on the Voodoo. (The cross plane crank illustration looks off too). The illustration just after that clearly shows the two center pistons rise and fall in unison. The voodoo engine sound with that different crank configuration, while high revving, is more like a traditional cross plane v8.
First time Chevy has raised my eyebrows in a while. Bout time they let one breathe !! Sweet !! Hand built/ production ?? Is it attainable. ?? We’ll see.
Great video accept for when explaining the flat plane crankshaft. You use a picture of the voodoo crankshaft that, while being a flat plane, is completely unique to itself and not a good representation of the typical rod journal placement of a flat plane crank.

The trans is by far my number one concern, not that I didn't already consider that when I bought my 17 GS manual C7 as the C8 was being introduced. That purchase gave me a chance to prepare for a future automatic, but with design flaws already determined in this 1st generation DCT I can only hope that a series II or III is underdevelopment and will show greater promise
Nice video. If I had the money, I'd buy one and put it in storage. This has to be the last ICE Corvette. Very nice FYI: Flat plane cranks definitely use counterweights
I can’t wait to see it work on a long track, I doubt one is in the books for us immediately but I can see how and why Gm did what they did, remember this engine it still in its infancy the potential is far beyond anything built today.
Great video! I learned a lot about this amazing engine. If it's everything GM states it'll be one amazing car! I am looking forward to it being put thru it's paces.
I forget what they call them but when they make the header tubes all exactly the same length and volume and how good it sounds on different Chevy V8's! Having something like that made for this engine would be mental I bet!!!
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.
Great video. Only thing I would add is about the dual valve springs. The real reason for using a dual spring is to prevent any potential valve float through harmonics.
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.
@@thedaredevil1907 there no known reliable FPC engines period. The fact tbey are using a proven to be unreliable valve train design says it all. Porsche used the same design years ago and had a lot of reliability problems that even cause them to lower the red line. Every high strung FPC engine is destined to die. McLarens shoot rods through the block... Vodoos are junk... Ferraris... Don't make me laugh.
One little detail - the flat plane crank showed is that of the GT350 and a very odd design because of their sound goals. Traditionally, and I'm the LT6, the flat plane v8 crank is just like that of an I4 with an up-down-down-up configuration.
"Gemini" also references its flat-plane crank - which, along with the two injection systems, means that it essentially amounts to two straight-fours on one crankshaft.
Well as of right now and LS7 is my dream engine, I love the Max RPM and the power output and just everything and sound about it. If I can go and buy an lt6 crate engine that my that my put my LS7 dream to rest, I've got a particular general motors car that I'm thinking of with a lt6 it's just a little Pontiac........
I think this is supposed to supersede the original 1990-1995 LT5 found in the original ZR-1. It was also a DOHC V8, however that was a regular cross plane crank. But they’re both marvels of their time.
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.
My mind always goes to how could the competition counter this great move? Toyota could come out with a mid engine platform with the supercharged V-6 standard and the LFA’s v10 As a Z06 fighter. Other than that manufactures are going to have to delve hard into research and development
A factor to consider is that Toyota is conservative with their "performance" cars. They're more about reliability. Reliability most of the times doesn't equal performance which excites the buyer.
They wouldn't even go to the effort to build their own Supra. They wouldn't even use their own V6, which makes more power than their Supra when in Lotus trim.
Smaller, lighter sport cars like Miata and S2000 can still hold their own on narrow twisty roads or dicing in the suburbs, with plenty of fun for a lot less money when you can buy a whole set of premium tires for the cost of one Z06 tire plus it's a lotta miles from my garage to somewhere I can use over 500HP!
Toyota probably wont bother to try to compete with Z06. Toyota lost money on every Mk4 Supra they ever sold. GM might build the C8, but how well is it actually selling? Nobody can afford these things right now lol.
It's about time GM put a proper DOHC 32 valve v8 in the Corvette. Yes I know about the LT-5. I knew GM could do it because of the 3.6 that came in the Camaro. That engine was a 335 hp v6 Boss.
Lt1, lt4, lt5 lt6, ls6, ls7are all rpo codes, the other letters in the alphabet you mention are already in use for other vehicle options, just not as well known. So rpo codes get reused through the years for different things. Usually a rpo code is used in tandem with the model year. Z71, z28, z34, zo6, zr1, zl1... all rpo codes just better known. That's why they refuse them. Gu6 and g80 are differential codes, different codes for open, limited or locker, as well as different codes for ratios. Along with every other option on the car having a corresponding code that varies in Identification of options from one model to the next. That's why they reuse and redesignate codes and typically keep certain codes for engine id and other drivetrain id.
The LT 6 has a has thicker cylinder walls with more space between each cylinder! It also has an insanely short stroke. n/a built is more of a feasible route this time around for a lot of power gains vs just throwing a supercharger, which is more complicated now or a turbo system. ;)
Really good informative video. very technical going to have to rewind a few times 🙄 as it went a little fast for me 😁 as in comparison between engineering/ platform. Differences generational similarities,, and advancements in technology.. thank you for no music background..!
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.
One rectification: the Tremec eight-speed dct on the C8 Z06 have code: M1M and for C8 Stingray the Tremec eight-speed dct have code M1L , so there's any differences and the new LT6 engine have IVLC Technology ( Intake Valve Lift Control included first time in Chevy Impala) it's similar like i-VTEC Honda's system.
Maybe I’m just an old man at heart (but 23) but I wouldn’t want a corvette that sound and looks like a Ferrari, but then again I drive a 4x4 1977 International Scout with a 304 V8 (5.0L) and a 4 speed. Totally different worlds. And don’t get me wrong, I think they are amazing vehicles and while it’s what the Corvette was supposed to be, it’s no longer the Corvette we’ve come to know and love. What we love them for either. Think about it. But I am glad they are always improving and making them better
Now they have hyper cars that make no sound. Electric with 1000++ hp equivalent. Just some tire noise...I love the new LT6 sound. I just think it is very soon to be extinct.
This seems like a copy of the Ferrari 458 engine which is a fantastic engine. However, I don't see that as a bad thing as it's hard to improve on perfection. I'm glad GM is building this.
The image of the flat plane crankshaft you used is from the 5.2 Voodoo from Ford. That was the only car to use that flat plane crankshaft design. Ferraris and the LT6 use a different design.
This car's going to be like the 2008 GT-R; I may buy one after the first year to ensure no harmonic vibration or other mechanical issues. But we have to ask ourselves, is this really a Corvette?
It borrows from the past also Rocket designation was from Oldsmobile ( 1940’s) Between bank throttles valves are like the Yamaha V-Max V-Boost (1980’s) 2020’s Racing tech brought to the masses.
C8. R wrapping up consecutive championships today at Petite Lemans. It's going to be interesting going forward with the demise of the GTLM class. The new classification and competition is going to make IMSA sports car racing even more exciting. 🏁🇺🇲🏆 /=[=]=/ 🏆🇺🇲🏁

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.
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.
Great video. Only thing I would add is about the dual valve springs. The real reason for using a dual spring is to prevent any potential valve float through harmonics.
excellent coverage..the most in depth of all ive listenned 2...n/ive heard alot..thancs.
LT-1 was used in the 70s as well. It was a hot 350 small block. They also had a LT Type.
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.
Maybe the ability to "build pressure" via the velocity stacks helps.
@GT Content Porsche had velocity stacks in the 996 I believe it was. They were vacume adjustable.
Best video on RUclips! Beats even the biggest channels! This was super informative 🏁👍!!
Glad you enjoyed it!
GM absolutely nailed it with the C8. This new engine is incredible!
Most powerful N/A V8 period, not just flatplane!
the Z06 is one sweet ride, cant wait to see it
It is not one of the most powerful N/A V8's ever, it is THE MOST POWERFUL N/A V8 ever.
Sounds great race engine for the streets. I’m excited and want to get one but I think I’ll just get a C8
Not an ideal engine for street use.
@@Outtacontrol304 how do you know they arnt out?
@@Outtacontrol304 yes they are just not as built from factory buddy
@@thedaredevil1907 there no known reliable FPC engines period. The fact tbey are using a proven to be unreliable valve train design says it all. Porsche used the same design years ago and had a lot of reliability problems that even cause them to lower the red line. Every high strung FPC engine is destined to die. McLarens shoot rods through the block... Vodoos are junk... Ferraris... Don't make me laugh.
@@gailliardander yeahhh are you high? If fpc engines were ideal for steet use then everyone would use them in everything.
very amazing character-body design. sf90, c8 z06, nsx 2nd-gen 😱all of them
One little detail - the flat plane crank showed is that of the GT350 and a very odd design because of their sound goals. Traditionally, and I'm the LT6, the flat plane v8 crank is just like that of an I4 with an up-down-down-up configuration.
"Gemini" also references its flat-plane crank - which, along with the two injection systems, means that it essentially amounts to two straight-fours on one crankshaft.
Incredible engine!
Good to see you!!! New corvette Z06 is pretty nice
Excellent content very well thought out! Love it 👌
Well as of right now and LS7 is my dream engine, I love the Max RPM and the power output and just everything and sound about it.
If I can go and buy an lt6 crate engine that my that my put my LS7 dream to rest, I've got a particular general motors car that I'm thinking of with a lt6 it's just a little Pontiac........
This is an awesome video. Thank you. In the Z06 list. Fairly low so learning as we speak
I think this is supposed to supersede the original 1990-1995 LT5 found in the original ZR-1.
It was also a DOHC V8, however that was a regular cross plane crank. But they’re both marvels of their time.
CHEVY IS TRULY THE HEARTBEAT OF AMERICA!!!!!!!!!!!!!!!!!!
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.
yep was about to comment this
You have to love the engineering!
My mind always goes to how could the competition counter this great move? Toyota could come out with a mid engine platform with the supercharged V-6 standard and the LFA’s v10 As a Z06 fighter. Other than that manufactures are going to have to delve hard into research and development
A factor to consider is that Toyota is conservative with their "performance" cars. They're more about reliability. Reliability most of the times doesn't equal performance which excites the buyer.
They wouldn't even go to the effort to build their own Supra. They wouldn't even use their own V6, which makes more power than their Supra when in Lotus trim.
That would be like shitting into their own lunch bag because Lotus wouldn't want to use toyota engines anymore, if they became a competitor.
Smaller, lighter sport cars like Miata and S2000 can still hold their own on narrow twisty roads or dicing in the suburbs, with plenty of fun for a lot less money when you can buy a whole set of premium tires for the cost of one Z06 tire plus it's a lotta miles from my garage to somewhere I can use over 500HP!
Toyota probably wont bother to try to compete with Z06. Toyota lost money on every Mk4 Supra they ever sold. GM might build the C8, but how well is it actually selling? Nobody can afford these things right now lol.
It's about time GM put a proper DOHC 32 valve v8 in the Corvette. Yes I know about the LT-5. I knew GM could do it because of the 3.6 that came in the Camaro. That engine was a 335 hp v6 Boss.
Lt1, lt4, lt5 lt6, ls6, ls7are all rpo codes, the other letters in the alphabet you mention are already in use for other vehicle options, just not as well known. So rpo codes get reused through the years for different things. Usually a rpo code is used in tandem with the model year. Z71, z28, z34, zo6, zr1, zl1... all rpo codes just better known. That's why they refuse them. Gu6 and g80 are differential codes, different codes for open, limited or locker, as well as different codes for ratios. Along with every other option on the car having a corresponding code that varies in Identification of options from one model to the next. That's why they reuse and redesignate codes and typically keep certain codes for engine id and other drivetrain id.
The LT 6 has a has thicker cylinder walls with more space between each cylinder! It also has an insanely short stroke. n/a built is more of a feasible route this time around for a lot of power gains vs just throwing a supercharger, which is more complicated now or a turbo system. ;)
Really good informative video. very technical going to have to rewind a few times 🙄 as it went a little fast for me 😁 as in comparison between engineering/ platform. Differences generational similarities,, and advancements in technology.. thank you for no music background..!
Very good information about the complex engine history.
I can't wait to see the C8 Zora, Twin turbo hybrid all wheel drive electric motors in the front and V-8 rear 1200+ HP.
Still a LOT of crazy improvements to come, should be exciting for years to come.
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.
Wow! One of the best illustrations I've seen, Chevy should hire you as their spokesman. :) Thank you for this Video.😊
Glad you liked it!
Wow! Thank you for talking about all these things! 🙂👍
You're welcome!
The flat plane crank they showed in this video was a Mustang GT350 flat plane I noticed and not the C8 ZO6's.
One rectification: the Tremec eight-speed dct on the C8 Z06 have code: M1M and for C8 Stingray the Tremec eight-speed dct have code M1L , so there's any differences and the new LT6 engine have IVLC Technology ( Intake Valve Lift Control included first time in Chevy Impala) it's similar like i-VTEC Honda's system.
Who knew Don Imus had his own race series? Bet it was sick!
Great video content. Thanks for putting it together.
I was kind of surprised there was not mention of the LT5 since its the only other DOHC engine ever used in the Vette.
yep
Lotus heads
WOW!! The Pontiac Fiero finally reached its full potential, by disguising itself as a Chevy to sneak pass the bean counting execs at GM.
8:00 gave me the feels
This thing is going to be bananas under boost.
I hope gm performance made twin turbo v8 for new ZR1
LT6 was an awesome 454 in the late 60's early 70's
Maybe I’m just an old man at heart (but 23) but I wouldn’t want a corvette that sound and looks like a Ferrari, but then again I drive a 4x4 1977 International Scout with a 304 V8 (5.0L) and a 4 speed. Totally different worlds. And don’t get me wrong, I think they are amazing vehicles and while it’s what the Corvette was supposed to be, it’s no longer the Corvette we’ve come to know and love. What we love them for either. Think about it.
But I am glad they are always improving and making them better
Now they have hyper cars that make no sound. Electric with 1000++ hp equivalent. Just some tire noise...I love the new LT6 sound. I just think it is very soon to be extinct.
@@polystictus sadly true.
Both of the crankshafts in the pictures are flatplane. It's just that the asymmetric one is from the GT350 mustang
Dude u are awesome. I like how u make all that complicated info come across only wish I understood all instead of some of it 🙃.
This seems like a copy of the Ferrari 458 engine which is a fantastic engine. However, I don't see that as a bad thing as it's hard to improve on perfection. I'm glad GM is building this.
GM bought a Ferrari 458 for test comparisons with the Zo6.
@@GTContent good choice. I have a 458 Spider and an 812 Superfast. I guess adding 4 cylinders is improving on perfection
I was going through the comments to find exactly this. I thought the same. Ferrari V8 on steroids
You could even say the whole car has Ferrari essence. 🤔
The image of the flat plane crankshaft you used is from the 5.2 Voodoo from Ford. That was the only car to use that flat plane crankshaft design. Ferraris and the LT6 use a different design.
At 5:02 picture of the cross plane vs flat plane crankshafts. They are both flat plane. One is from LT6 and another from Shelby GT350.
So, we haven't even gotten the C8 ZR1 model yet!!!!!!!!!!!.
The C7 ZR1 was insanely awesome!! 😳
I remember being completely blown away by the c6R, now I see the new c8R and just doesn’t feel so crazy compared to the competition
Perhaps one of the last pure sports cars before electric foggotry is forced upon all new cars.
I am surprised that they made such an engine while various regulations were being enforced. Great effort!
Amazing sound as good as the V-10 Porsche Carrera GT.
Which cost $450,000 in 2004!
This car's going to be like the 2008 GT-R; I may buy one after the first year to ensure no harmonic vibration or other mechanical issues. But we have to ask ourselves, is this really a Corvette?
You’ll be on a waitlist forever anyway so you won’t have to worry about first year problems
Zora designed a mid engine Corvette in 70s and DOHC on c4 ZR1. Corvette should have evolved to this after the C5… but money, packaging, and politics.
Zora actually wanted a mid engine Corvette in the 1960’s the C2 was supposed to be mid engine but Chevy wouldn’t do it.
It borrows from the past also
Rocket designation was from Oldsmobile ( 1940’s)
Between bank throttles valves are like the Yamaha V-Max V-Boost (1980’s)
2020’s Racing tech brought to the masses.
C8. R wrapping up consecutive championships today at Petite Lemans.
It's going to be interesting going forward with the demise of the GTLM class. The new classification and competition is going to make IMSA sports car racing even more exciting. 🏁🇺🇲🏆 /=[=]=/ 🏆🇺🇲🏁
That picture of the flat plane crank you shower clearly had counter weights
