I'll post up my current spec in a new thread with some photos.

McLaren did cut the price of the MSO Black Pack in half earlier this year, but it is still 18 bills... I would hope for that money the parts are at least lightweight carbon fiber and not just the same heavier standard palladium pieces painted in high gloss black. I know fro personal experience MSO CF diffuser is much lighter than the palladium one, same for the MSO CF wing compared to the painted wing. Same should apply for the front splitter, rear bumper, and hood. The smaller carbon bits i.e. air intakes probably don't make much difference.

I was wondering if someone can clarify what is actually carbon fibre on this car. The snapshot from page 39 of the product brief below indicates that the front bumper, splitter, rear bumper (?the painted bit or the palladium/CF part), diffuser, side skirts etc and the active wing are already made of CF (and painted where applicable) or do you think they are just referring the optional pieces although there is no option for CF front bumper.??????

Did some more reading...................
In the weight loss table below it refers to 14.3kgs being from new carbon panels (presumably standard) so I'm thinking the answer is yes!!

I think I've answered my own (and Kovalser's) question

That would also explain the black pack being cheaper but annoying that visual CF is still so expensive. Because they can.

@ksp Yes that is all correct... basically the MSO Black Pack is $18k for gloss black instead of palladium paint 🤪

After seeing those pics, I’m happy with my decision to avoid the scoop and spec the carbon rear wing.

Me too

This is the Novitec scoop on my 720S. It obviously does nothing productive. I just like the way it looks and it makes my car a bit different than the many other 720S here in town. It was relatively cheap ($2,500) and no significant labor to install, so I bought it. Same with the Vortsteiner side blades.

I expected the LT to have something similar, but functional. Basically an integrated air channel into the T-shaped roof which would enter the cabin at the top of the rear windshield then enter the engine compartment (for whatever purpose) at the back of the cabin via a single center duct or branched ducts running along the C-pillars.

According to McLaren, there was no benefit from using the scoop for additional intake air on the 765LT and instead repurposed it for passive cooling. Are the engine air intakes that much better on the 720S platform than in the Senna, P1, 600LT, and 675LT ? No doubt they are an engineering marvel.

I hate to say I feel the Roof Scoop execution on the 765LT is a miss. I wish the interior execution was more like the Senna, down and around the side instead of a straight down pipe ruining your jet fighter pilot view. I'm not convinced you'll get the same sounds as the previous LT's because it has a completely different function and supposedly non functional at all.

From what I read it is more than the $36K as you have to have the glazed engine window which is another ~$8K. So for almost $45k you get a halfway snorkel that may or may not keep your engine bay any cooler.

Perhaps Novitec will come up with something similar for the LT

The Novitec scoop for the 720S should work on the LT too no? I'm wondering if you couldn't find a good body shop to mold the Novitec scoop into the T roof section for a factory look. Assuming you could easily replace the roof should it get buggered up.

I've seen a few pictures of that Ceramic Grey car with the MSO scoop from the front and front quarter and from those angles it does look pretty awesome. Just the angles where you see how it's attached to the glass I'm not sure I can ever get used to that. It's a love hate scoop!

What do you guys think? Looks much smaller in real life vs rendering.

It looks like two-thirds of the surfboard broke off from the roof rack! Really not appealing.

 

[Dracarys]

Looks horrible like it was stuck on.

Exactly, and MSO probably wants an arm and a leg for it! The 600LT roof scoop actually looks good but im not really a fan of unnecessary super expensive options anyway.

 

[Bogan69]

A larger engine view cutout would be good. 720 has a prettier looking engine than the 570. Well, that nice machined logo in aluminium looks better than the Tupperware box on the intakes in the 570 at least.
Thats one of the things i love, seeing engine porn. Need more.

Need to see more pics, but I still have the roof scoop spec’ed on my car. Sure it’s F-all expensive, but as an engineer I like the idea of optimizing the car as much as possible. It gets well over 100F in my area, so any extra bit of cooling is worth it. I have a feeling there will be a reasonable way to wash out any bugs and debris off the manifold, if only just basting a pressure hose stream down the gullet of the scoop. It is also one of the few unique option you cannot get with a Spider, so it may generate a two-tier pricing scheme in the future second-hand market.

Looking at the route of the interior duct, it starts wide and gets narrow, which will accelerate air collected by the scoop to generate a faster-than-driving-speed airflow over the engine. The split design of the 600LT, Senna, etc works because they are the induction routes, so air will be sucked through the ducts irrespective of the exterior air speed. With a ram-air system for semi-passive cooling, I believe the split duct would actually result in slower airflow into the engine bay (longer path, more surface friction, more bends, etc) compared to this design.

Overall, it seems very McLaren. Not necessarily the prettiest, but likely extremely well engineered and beneficial to the package as a whole.

How much cooler will the engine bay be when it is is sucking hot air in? In cooler climates I get it but not when it is warm or hot out.

Basic thermodynamics. If you accelerate air over a hot surface, it cools down that surface by displacing the hot air immediately nearby (convection). Same reason a personal fan makes you feel cool when your room is hot, or why you blow over hot food before eating it. It’s the same way your intercoolers can keep engine temps normal when it’s really hot out. The surfaces of a car engine are >150F, and ambient temps are not usually more than ~100F. That’s a 50F differential, which will result in more effective cooling than if the engine bay does not have the additional airflow.

This is coupled with the fact that the scoop increases the local pressure in the engine bay by providing another forced air source into that engine bay. This in turn forces more hot air out of the engine bay, replacing it with cooler air from the local environment, thereby enhancing cooling.

 

[kovalser]

The 765LT engine bay seems well ventilated through all that new mesh. If the scoop design really helps cooling, McLaren should publish some actual figures showing difference in engine and charge air temperature with and without it, and also how it effects heat soak.

Agreed, though they did publish a 10 deg. reduction in engine temps in the tech brief (admittedly without real data presented). There is no doubt more inlet air will help cooling (see post above), but how much is a valid question. We are left to assume they did their homework.
