2025 Corvette ZR1 LT7 Engine Walk Around

[@Tharley87]

GM gives them this level of access because I think they see kindred spirits with the guys behind SG. This is the best car content on KZbin.

[@lukewalker1051]

Kindred spirits...lol. More like, free marketing. It is very hard to sell a $200K vehicle in a bad economy.

[@Tharley87]

@ with all due respect, GM could select much larger KZbin channels for this, channels that would provide much more “free advertising”. They gave SG this level of early access on the Z06 as well because I think they appreciate someone that wants to get this far into the engineering aspect of the car. They have now done the same with ZR1. They gave Jay the first drive on Stingray and I believe Z as well. Jay got them the most free advertising.

[@INFINITYLI97]

More importantly, most of the corvette engineers watches SG 😂

I think the Lucid and GM engineers really like this channel, its nice to have people appreciate the work put into these cars. Im not really a fan of the styling but the engines on these Corvettes are just so cool.

Out of any Automotive Journalists out there I'm so glad they let you guys take a look at this car before production. Because of this, I've actually learned about the car, and as an extremely nice bonus the whole thing is presented beautifully. (Talking about both videos)

[@Zath88]

Still cant believe there are people out there (mostly lead poisoned boomers) that still think this isn’t a “real corvette”. The level of craftsmanship and engineering that went into not only this ZR1 but this whole C8 generation is just next level. Hats off to GM for making this THEE Corvette

[@spdcrzy]

This is a hundred MORE horsepower than what the hypercar Agera R, for reference, did on pump gas ten years ago. And it cost two million dollars. On E85, this engine is probably capable of well in excess of 1200 horsepower at MINIMUM.

[@2010ngojo]

Super low production, probably hand crafted and assembled car vs this? Yeah I'm not surprised production costs are vastly different. While the production number probably won't hit over 10k, maybe 15k max, the zr1 benefits from building off the C8 platform. And they sold relatively a lot of C8 corvettes.

[@kevinnickens]

The depth of this video is so good. SG knows exactly the kind of car enthusiast their audience are, and nowhere else on YT can we get this amazing content.

[@davevan9150]

[@99-Zulu]

Did they ever give a reason why they are running two mono scroll turbos instead of two twin scroll turbos? If they are wanting to reduce lag wouldn't the dual twin scroll turbos be able to further reduce turbo lag?

[@geerstyresoil3136]

I remember reading since they are running electric wastegates they can utilize programming anti-lag system is designed to reduce turbo lag by maintaining turbocharger spool during rapid throttle changes. This is achieved by keeping the turbine spinning even when the throttle is lifted, ensuring quick boost recovery. It adapts to driving style, optimizing power delivery in high-performance scenarios. While specifics for the ZR1 aren't fully detailed, typical anti-lag systems use strategies like ignition timing retardation or bypass air flow to keep the turbos active without creating significant stress on the engine.

[@99-Zulu]

@geerstyresoil3136 I see I knew there was an anti lag system installed. I just figured utilizing a dual twin scroll setup would be more beneficial than the dual mono scroll setup that they are using. Mostly knew to the turbocharged world. Been mostly driving na engines for most of my life so I just figured using the twin scroll would have been a better option.

[@phillyphil1513]

yes it does seem strange, but i think the problem with Twin Scroll is ultimately on the top end (since TS is an optimization for low end response on the street). at the top end (like when you're going for a rating of 1064hp) Twin Scroll acts a restriction, which is why you generally don't see it used in Motorsports and Racing (think Drift, Lemans, F1, etc) where the whole point is to spend as much time as possible at WOT. it's very similar then to the idea of fitting a Close Ratio Transmission where you optimize gears 3, 4, 5, 6 and ignore 1st and 2nd, because ideally 1st and 2nd are only used at the start of the race, and never engaged again until after the checkers.

[@chbrules]

I'm so glad you guys get this sort of access. I really appreciate your technical insight and interviews with these people more than any other channel. Other channels will gloss over these details reading a script with lists of specs. You guys talk about those details, and I love that so much more!

SWEET machine. I hope GM never goes away. the corvette is pure american beauty, every inch. sure, mclaren, ferrari & Lambo can make beautiful, fast, well handling track cars too... but GM does it at 1/4th the price and no $5000 oil changes or $20k fuel cell changes. what a sweet running car.

[@CarsandBikes]

WOW. CNC heads. Are the pistons partial skirt for reduced mass? Anyone know what the oil consumption is like for either engines?

[@JJVgaming]

In the transmission section of the video, Dustin mentions the transmission possesses the same gear ratios as the Z06.. I wonder if the overwhelming power advantage / low end torque of the Zr1 will negate the long 5th gear issue the Z06 had at the Nürburgring

[@GadgetyMV]

In the Chevrolet Pressrom it says the engine output is 1064hp/873 kW at 7000 rpm. Except, 1 kW is 1.34 hp, so that would mean 1170 hp. Conversely, 1064hp, where one hp equals 0.7457 kW, would mean 793.4 kW. Either way, one number stated is wrong. It could be a typo...

Turbo speed sensor? I wonder what the engine management program does with the information since turbos spin up with exhaust pressure. Compare first and second derivative, see that max turbo RPM is approaching and then what? Variable vanes? Close the throttle? Does it intervene a lot? Would like to know more.

[@customurlgoeshere]

[@phillyphil1513]

unfortunately no, many don't realize how HEAVY turbo assemblies can be (before you even add the weight of an integrated manifold) so i bet the reason they positioned them where they did was to additionally address WEIGHT OPTIMIZATION and keep a low CoG. "BRILLIANT...!!!" (2 old guys drinking Guinness voice) yeah that's how i'd do it, so GM Engineers "didn't miss a trick" with the LT7.

[@DisturbedBurger]

@phillyphil1513 with a hot-v I'd think weight would be saved? One of the advantages to a hot-v is less tubing and shorter distance from turbo to intercooler to intake valve 🤔

[@Tothefloor]

Zora will be the car to have for overall performance. Old school people will prefer the Zr1 though so that's cool. The ZR1's 1000hp and 2wd is just a recipe for ZERO traction. It won't even come close to competing to other 1000hp cars with AWD in a straight line and on the back roads as well. No AWD pull out of the corners. I bet the 60-130 times will be only mid 5's where a Plaid is mid 4's. Apples to Oranges though I know.
