    Re: Mclaren 765LT

    Agree. Fantastic and very impressive car, but I can’t believe downforce at low speeds is anything other than miniscule.

    Re: Mclaren 765LT

    Don’t forget the first man powered airplane, the Gossamer Condor, flew between 10 to 11 mph so even at slow speeds aerodynamic forces are present.  Whilst McLaren hasn’t divulged much on the aerodynamics package, the location of the exhaust could work in cooperation with the rear wing much like the blown diffuser did on McLaren’s F1 cars.

    When I was in High School, I had a semester internship with the founder of that company, Paul McCready.  Was a good time Smiley

    I built some flying radio controlled glider prototypes with them.

    Re: Mclaren 765LT

    Wow!  What a tremendous learning opportunity. AeroVironment pioneered low speed aerodynamics.  I never had the chance to work with them; however, I worked with the chief aerodynamicist of Scaled Composites and the former president of Piper Aircraft.  Every once in awhile I get the urge to build a microfilm model to fly in the great room.  
     

    Returning to the subject, I do wish that McLaren would follow Ferrari’s lead and publish more information on its aerodynamics.

    How could aero help with traction off the line? 

    As the 765LT moves away from the line the rear spoiler rises into its air brake position to increase rear axle loading.  Aerodynamic forces are present with air flow of any velocity other than zero, albeit those forces increase with the square of the velocity.  Even a small amount of downforce helps provide increased traction over the 720.  As the car continues to accelerate, the rear spoiler retracts to mitigate the increase in drag associated with the increasing downforce. 

    But maybe I'm wrong - whatever they're doing, it seems to be f***ing fast Smiley

    Re: Mclaren 765LT

    Same dyno:

    720S 659 WHP

    765LT 769 WHP


    At 13% drivetrain loss it's about 885HP smiley


    Re: Mclaren 765LT

    These US dynos are pretty useless at measuring manufacturer engine power, a 6 or 7 second power run on a turbo car really does not cut it. The talk of 100+ more WHP than the 720 means nothing whatsoever in relation to manufacturer measured braked engine dyno hp.

    Wait until one of these is measured on a MAHA dyno, I think it will be more than 765PS but only by 20PS maximum

    They are saying 110hp more than the 720 on that dyno so I guess 720+110 = 830..... I am thinking it may have the same output as the Senna so it is ballpark right kiss

    3rd - 2020 Ford Mustang Shelby GT500

    Lap Time: 2:44.6

    The GT500 has an intimidating amount of muscle underhood—enough to make you check your shorts. (If you haven't heard, it's the most powerful production car ever to come out of Dearborn.) The Mustang tests your mettle on every stretch of pavement. If you're brave enough to keep your foot in it, though, this 760-hp pony car will give you the ride of your life.

    2nd - 2021 Porsche 911 Turbo S

    Lap Time: 2:42.5

    It isn't breaking news that 911 Turbos are fast, or that we love them. This 2021 Turbo S, packing a 640-hp twin-turbo 3.7-liter flat-six, delivers 60 more horses than the last generation's 3.8-liter. This latest Turbo S bursts out of Turn 1 at 82.2 mph, the fastest speed we've ever recorded. What caught our attention, though, is that it broke into the all-time top 10 with relatively ordinary summer tires. What might it do with track rubber?  

    1st - 2021 McLaren 765LT

    Lap Time: 2:38.4

    Best lap time of the year? Check. Third-fastest of our 14 Lightning Laps? Yep. Is 174.6 mph on the front straight any good? It is. In fact, that's the highest speed we've recorded at VIR. The 765LT's 2:38.4 time lands it just behind the McLaren Senna and the Porsche 911 GT2 RS Weissach. What's crazy is we probably left a few tenths on the track. Always read the manual, friends. You never know what you'll find in there.

    During some days of the year, the morning, noon, evening temperature could easily be at least 20 degree difference on any given day and 20 degree difference for turbo intake temp is a lot.

    Re: Mclaren 765LT

    Because of the excellent Porsche GT cars, people always overlook the turbo S.

    turbo Ss are always up there somewhere in comparisons, maybe not the best best, but it can hold it's own.

    They are the best all around sports car. Bar none. Nothing come close. Multi-role too, you want a canyon carver, it can be one, you want a highway eater, it is so too, even compliant enough for day to day city driving on bumpy roads.

    They have a huge breadth of ability for sure.  They do everything well, but only a couple things great (like crossing a continent at high speed in any weather). 

    And they can crush a race track (along with its tires), but your pulse will barely be above its resting state.

    I think a Boxster 4.0 with Manual is probably much more satisfying as a canyon carver, for instance.

    Re: Mclaren 765LT

    I get my kicks from the lateral Gs pulled on corners. The rest are just a build up to the next sets of corners. 

    But yes, it's nice to hear an engine sing to 9000rpm, but that's still secondary to lateral Gs. 

    If one car can do 9000 rpm but can only pull 0.5G while another is muffled by turbos or silenced but can pull 0.9+G all day long, I will take the later. 

    I am warming up to the capability of the silent Taycan

    Re: Mclaren 765LT

    For me, I get the most fun when playing with a car at the limit.  It’s not that important to me where that limit is (even fun at very low speeds on slippery surfaces at low lateral g’s) 

    It is important to me that the car is super responsive to my inputs with lots of feel and feedback - makes dancing near the limit much more satisfying.

    Playing at the limit in a Turbo S on public roads is usually pretty irresponsible or worse - I know I couldn’t do it safely in almost any conditions.

    1000% agree - and if they would take a wet lap time and average the times - it would shuffle the deck massively.

    fully agree.....has always been one of the most complete sportscars since all wheel drive was introduced to it.

    and its also one of the easiest to own and drive.....a perfect product in many ways.

    Actually I was talking about money... Smiley My last serious track experience left me with a 4000 EUR bill...I needed two new rims (this happens when you slide through gravel Smiley and it is so bad that it cannot be repaired). Not worth it.

    Also, most of the track experiences I would be interested in are way too expensive, they start at 5000 EUR and more, I really need the money for different stuff, not willing to pay that much anymore to make my ego happy. Smiley
