Modified NASCAR ZL1 racing 2023 24 hour of LeMans

[6.0GTO]

No NASCAR restrictions so this car is just going to be faster. Jensen Button and Jimmy Johnson to be drivers. Car will run in the experimental class. I wonder performance wise what the closest class will be. Looks like the French are not use to an American V8.

They need to put the dr. Gas x pipes back on the cars.

Boom tubes...sound glorious

That was a glorious 5:18 of thundering V8 sound!!!

Thanks for post! Audio is fantastic.

2023, this weekend June 10-11, is the 100th anniversary of LeMans. But this is the 91st race. French civil unrest and WWII caused the cancellations.

Jenson Button is a pretty cool cat.



I subscribe to the Motortrend+ stream. They list 10 different live feeds, but it's kinda confusing to follow.

Gonna run a live feed for the Cup Camaro on Motortrend+.

Those combined with an x pipe in my opinion are the best nascar exhaust setup. I think they are running h pipes now in front of the boom tubes.

They dont even run the "boom tubes" anymore

I was basing that off the last cars I saw which wasn’t this next gen car. I am not sure what the setup is now.

Years ago Sterling Marlin had a rral cool x pipe setup at dega iirc...sounded like no other car on track...it was a beautiful sound...car ran like MFr too

I lie...it wad daytona


Comparison

This is what RCR was running on there cars back in 2019. I miss the sound of the 90’s stock cars. The x-pipe made them scream.

This is so cool to have a NASCAR entry in this race. I wish I was present to hear that Chevy engine roar. Great stuff.

Thus far during practice sessions, it is smoking the GT class cars by multiple seconds per lap. Corning speeds are down relative to the "street car" classes, but the extra 200-250 hp helps a bit on a track that is ~85% WOT each lap. It's also 250# lighter than a nascar.

The big question is whether or not a nascar engine can last 3k miles.

 

[MinGrey02Stg2]

No matter how close or far it is from the Nascar version regulation wise, it's damn cool to see it amongst those LMP cars.

This guy has a good channel about Nascar and a great video about the different exhausts.

Chevrolet is ready to capitalize on the ZL1 24 Hours of LeMans Camaro with a special edition production Camaro ZL1. The ZL1 Garage 56 Edition is painted Riptide Blue and features a graphics package inspired by the race car's design, including a stylized American flag on the hood bulge and roof.

56 of the ZL1 Garage 56 Edition cars will be offered later this year at a yet to be announced price, but the recently unveiled Camaro ZL1 Collector's Edition, which commemorates the end of the model's production next January, starts at $88,690.

I see

I hope this car does great at the race. That caveman pushrod V8 will hurt some feelings if it can last.

That motor can handle it...

By the way nascar is the sanctioning body...not the car lol

I'm sure the motor is fine, my question is pit strategy over the others... a 4 second/lap gap can get pretty small if they have 25min brake swaps

I’m sure they can build an R07 and make it last. Super Lates often run an entire season on a single SB2, they setup just has to be spec’s with longevity in mind. I doubt there’s a more scienced-out race engine design than the American pushrod V8.

I met Mitchell and his girlfriend about a year ago. We tried to put a project together but our goals didn’t seem to line up with those of the project’s intended beneficiary. He and his girl are good people.

I’d be interested to know what kind of setup they are using.

After last week's race at Gateway, we saw something with the new car us NASCAR folk haven't really seen before: exploding brake rotors from repeated thermal cycling. The super powered brake ducting that previously cooled the old car's 12.72" rotors rapidly overcooled the Next Gen's 15" front and 14" rear rotors. The old small rotors just stayed hot. This could be an issue in a 24 hour race. The car seems to be faster than anyone expected though. The French like it now, but they won't like it if holds together and really competes. I think the Hendrick built R07 will outlast any component on the car now that they are roller cam. This car seems to be under the supervision of Chad Knaus, so she'll be long legged.
