Chazzy. There you go, i said it 😂

Jeff, great video. Thank you.

Thank you for finally making a "What they don't want you to know" video that's actually technical and full of new information. This is the coolest consumer facing car analysis I've ever seen! It honestly doesn't even really make me upset with porsche -- the engine/transmission layout of the 911 vs the Cayman is a significant and legitimate separator, and as the 911 has no real competitor in the market it does seem reasonable for them to price for that market share and demand. I feel like we've known for a while that the cayman/boxster is probably not only a superior value to the 911 but a superior platform as well (you buy a 911 because it's a 911, not because it's the most logical way to design a car), and if they want to use the revenue from 911s to subsidize the production of 718s that's fine with me! . Incredible video, thank you again!

Does the manual 718 transmission have this same type of fluid cooling system/transmission oil cooler?

I.S.B. genius

What an amazing video. From a UK 🇬🇧 viewer.

Brilliant video❤

And this is a surprise?

aight guess its time to buy a GT4RS instead of a GT3RS

Hi Jeff, I have to commend you on your videos and the detail you provide. I was hoping you might be able to help me with my roof problem on my 2014 981 Boxster S. When the car is stationary, whether it is locked or not and the roof is shut it opens on it's own, sometimes after 1 hour or 1 day, it varies heaps. It has got to the point that I can't risk taking it out and leaving it unattended. Any ideas that you might have that could make troubleshooting the problem easier would be much appreciated. Regards, JR.

Thanks for the video! My 991 glovebox won't close. I noticed the two pins that hold the door closed are retracted into the glovebox door. Is the handle itself what causes the two pins at either side of the door to spring back out? Thanks!

Ive been fighting single cylinder misfires, no additional codes, fuel pressure is 105.000 hPa at idle. would that indicate a bad/going pump?

Hi,thanks for the informative video..do you have a part number for this kit?

Hey cheers for this Jeff. What a pleasure to watch. Thinking of getting my first boxster and inspired even more now to see the brilliance reflected in another area.

Great content and well explained 👌🏻

I was 981 exterior designer - we had to style the shared hood to suit both this and the 991. Some of the underbody and mechanical components are shared too. I fought to get specific door outer skins for it (whilst sharing the inner structure), as the 986/987 shared those with nthe 996/997along with the hood and initially the front fenders and headlamps. Having different outer doors allowed changing their section and getting the indentation leading to the side intakes. Also the more geometric front and rear fender sections. The financial trade-off (we worked to very strict budgets!) was losing the separate roof cover, which meant more of a hole around the roof well when open, but also allowed adoption of Audi TT components giving us a faster folding action and saving weight. 981 windscreens and A Pillars are different than the 991s too, being shorter. The whole idea was to get away from the "cheaper 911" image and give the mid engined cars their own proud identity - hence the "platteau" fender tops and vertical headlamps which reference the 906/7/8, etc. sports racers of the '60s. The height of the Boxster rear deck and luggage bay floor of the Cayman was increased by about 30mm during the program to accomodate an Audi TT in line 4 cylinder motor - of course the 4 cylinder eventually ended up being a boxer. Incidentally, the 981 exterior theme was chosen at end of 2007 and production versions signed off by early 2009. The 918 program started in September 2009 to preview the new fender themes on a halo car and as a limited production program was completed and appeared before the 981s were introduced. The GT4 was originally never meant to happen, but, after the events of 2009, Piech, now in control, departed from the previous dictum of not allowing the 911 to be rivalled in performance or dynamics and said "let them fight". That one got the GT3 cooling package and front end, hence the vent in front of the hood....

A 356 is even easier to work on.

Excellent illustrative lesson on the excellent PDK. Chalk it up to the Italians for creating the modern Electro/Hydraulic actuated gearbox. Although my old F355 F1 box does not use a twin clutch (single), nor is wet (dry). Fortunately (for it wears faster) it is relatively easy to replace the clutch as it’s at the end of the gearbox. Fortunately too, it is otherwise a robust unit. It’s also much slower to shift, although still faster than the equivalent manual. Throttle blipping by one’s own foot, makes it all the more smoother experience. Oh and the F1 unit does not use a parking pawl, nor does the DCT in my Alfa 4c. I would also submit that the American Engineered Tremic DCT that has been supplied to ford (GT500) and C8 Covette is every bit as good as this PDK unit. Extremely robust unit. And of course let’s not forget Ferrari within multi iterations remains a leader in this field.

I owned a delightful 981 Boxster for years. I also owned a 992 Carrera for 3 months. It misses the mark in so many ways IMO; too big, cheap details, and frankly unexciting, unless your going ludicrous speeds.

Genius! Love your work sir. Have also loved your dissection threads on the M54 engine, so good! Greetings from New Zealand

Hi Do you know how to regulate the rope tension for the flap shown at the beginning?

It’s a shame we have to this for these cars, good back ground on explaining this with water based glue. I did my driver side about 4 years ago on my 991, I used liquid nails, now my other side is failing and I will look to get the3M product, impressive on your clamp 🗜️ detail. Good job mate.

Great insight.

Amazing

Your channel is something special. Not another obnoxious car guy cunt. You’re really passionate, your video are subtile, you can explain on a level that’s in depth but understandable. You can talk you don’t take thinks for granted but had to work for it. Keep it up, thanks for being an enrichment to car TH-cam.

Hi. Ive taken a dead battery out of my 2016 boxster 981. Was unable to maintain 12volts during the removal as all was dead. New battery on the way. What do i do to avoid issues with the electronics when installing the new battery ?

I absolutely love the models you created :D 100% creativity - 0% of stupid cost. Brilliant!

Great video and information ❤

Bloody cool.

You just pissed off thousands of 911 owners. Yikes!

Wow!!! Amazing tech explanation. Probably the best I ever saw. Thanks

😮unfortunate porshe not many buy it, somehow people just forget its name. PORSHE should do new sales strategy like toyota or mitsubishi

I always thought that it would be financially insane for Porsche to make the Cayman and Boxster, so I always figured that the vehicles were way more closely related to the 911 than we have been told. My friend's dad who worked for Porsche for decades used to always buy the newer 911 until he started "downsized" to the Caymans lol. I asked him why and he flat out told me that the 911 is a marketing thing these days, and not worth it unless you specifically want 911 things.

Damn, your videos are good, Jeff. Thanks for this.

What is the purpose of the vacuum pump? Is it for the brakes? Only for PDK? Do you wait for it to fail before replacing? Or should it be preventative like the AOS?

Porsche also does a great job keeping old parts available too. Audi should learn from this.

I commend you for your intelligence.

Nice structured and amazing video! Are things different for the 987 Cayman?

i have done this with bathroom scales

Great tip. A point about torque on a fastener that most people ignore is that the fastener has to be moving when the torque is reached, or it isn't accurate. What this also means, when using a torque wrench that clicks when the number is reached, is that multiple clicks (or multiple pulls if using a luggage scale) doesn't 'improve' or 'verify' the torque.

Thanks a lot for this great video. I have a 991.2 and a smell coming from my AC when I turn it on - the car was standing more than driving before I got my hands on it 1/2 year ago lol. I read a lot about this and I think the best solution is to directly spray on the Evaporator a disinfectant (must be at around 23:10 where you show it). 1) Do you think the evaporator is easily accessible with the tube from the disinfectant spray when the interior air filter is removed? At around 23:40 is the evaporator in the front, but there is another one (??) behind? Or is it something different?

The only difference that matters is engine layout. It is only natural that the Porsche model range has common parts, parts-sharing is the norm of 21st century and you can also find Mercedes E-Class parts in C-Class or Mercedes SUVs. No large-scale manufacturer will make bespoke components for high-volume cars.

Your a one man workshop manual……thanks you so much 👍

I have the very same scale;-) thank you for this great tip;-)

Hi Jeff, I've bought a damaged 981 Boxster GTS from a Sydney auction and am on the hunt for parts to repair a LH front suspension accident on the 2015 .... do you have any suggestions for parts - front bar, LH haedlight, suspension companents and airbag kit.

I thought of using the luggage scale before, but I did not thought of using the wood or pipe as extensions!

Brilliant

Outstanding

Jeff is the realest for this

Very interesting !
