Making of: Porsche 911 (997) Turbo Cabriolet PDK

To celebrate the first anniversary of my Porsche 911, I show you the same as I did with the Veyron some months ago: a timeline of car development.

The design time for this car was specially long, because the car is very very complex and I needed some time to build others MOC as the Lizard 8x8 or huge Bridge-layer (not presented here) to keep mi head clear.

The design of this car started after finish the Veyron.
Initially the idea of ​​building a second car so fast it was only for one reason: use in it all the mechanisms developed for the Veyron but I couldn't use, however some time after it was much more than that ...

Also if you look closely you can see things never show before...



12/20/2009. First gearbox type, too many gears and fricction. FAIL


01/12/2010. Starting with the second gearbox, more simple and efficient


01/28/2010. Second gearbox almost finished. With 7+R speeds and a 5th driving ring to select between even and odd gearboxes. Also it had one friction clutch to connect the gearbox to the central differential.


02/2/2010. Starting with the rear axle, first version was double wishbone suspension.



02/20/2010. The front McPherson axle. It only received a little modifications up to the final version used



03/25/2010. The beginning of the chassis ...


05/17/2010. The chassis is growing with all elements. The yellow bricks simulating the two lithium batteries.


Compared with the Veyron, the Porsche is a little bit longer and high


07/28/2010. First powertrain finished, it used 4XL motors. This powertrain was discarded after for to be too big and heavy...


08/10/2010. Continue with the unibody chassis


08/13/2010. Starting with the thrid gearbox, much more efficient and reliable.


09/09/2010. Second powertrain finished. This is the final powertrain used, real dual-clutch gearbox.


10/04/2010. Installed the accelerator on the batteries.


10/10/2010. Chassis nearly finished and adapted to the new powertrain.


01/11/2011. Starting with the bodywork.


01/14/2011. Bodywork growing..


01/30/2011. The front of the car nearly finished


02/11/2011. In that moment I decided change the rear axle, to other more complex and realistic. It changed from double wishbone suspension to multi-link


02/16/2011. The new rear axle mounted on the chassis. The red driving ring of the right is the handbrake.



03/11/2011. Continue with the folding top.


03/20/2011. Interior finished.


04/05/2011. Rear bodywork nearly finished. There you can see the speed indicator and the folding top guides.


04/10/2011. The adjustable spoiler.


The next three weeks I was fixing some little details of the car

05/01/2011. CAR FINISHED and officially presented in MADbrick Event

Wow, it takes a long time to create a masterpiece like this!

tuur said...

nice but could you make instructions for a folding roof or a spoiler
because making a chassis and axle's aren't that hard but if i want to add something i can't

tuur
p.s. wath's about the crazy slope video pronounced a time ago

Hi sheepo,
Could you please explain how the brakes and the accelerator work?
Many thanks in advance,
Pau

Hi, can you share how the clutch change works? Very nice work indeed on the gearbox and the chassis!

Sheepo said...

I am sorry for this, but the gearbox internal mechanism is absolutely secret.

Anonymous said...

so its not ok if I share my reverse copycat gearbox?

Anonymous said...

I don't mean to touch your work or take credit in any way for it, but I think your gearbox photo's in combination with the video is to exposing (especially for the gear shift system). I would recommend to blur the photo's even more to be sure no one copy's / reverse engineers it!

Great work on all your moc's!

Sheepo said...

The gear shift mechanism is easy to copy, but only with that it can't work properlly. The key in this gearbox is the clutches shift mechanism, and it is impossible to copy with only the image and the video...

Same anonymous. Please for Lego technic's sake go work at TLG. Maybe some kind of free-lance Lego designer! Anonymous out.

exellent work!!!.Where did you find the RC motor???

Sheepo said...

I buy my parts in bricklink.com

John Daniels said...

I want to sort my lego collection and I was wondering what brand and where did you buy the bins and enclosures?

Sheepo said...

You can buy it in any supermarket... in tools section.

Hi sheepo, was there a reasom why you used 2 of the Old Motors Instead of 2 modern Ones?

After seeing your work I have just started with my first moc-car - you really do inspire me

Sheepo said...

The reason is very easy, the old RC motor, is the most powerful motor ever produced my Lego... but it has a big problem, you only can connect one RC motor per battery, for that, so this car uses 2 batteries.

John Daniels said...

Thankyou. I have to agree with you completely on your transmission selector keeping it a secret after a year of work I wouldn't tell anyone either. --John

Ive been watching ur photos of the gearbox for 5 hours and im building it for my own porsche. You mind if i use it?

Sheepo said...

I say it again... you are free to try copy the gearbox, but the gear itself mechanism is easy to copy, but only with that it can't work properlly. The key in this gearbox is the clutches shift mechanism, and it is impossible to copy with only the image and the video...

Anonymous said...

Yes but i know how it works now im building it :)

Anonymous said...

please

Anonymous said...

Anonymous said...

hi im trying to make a porsche myself could you give me some advices?thank

Anonymous said...

Did you already disassemble this? It seems much better than the Veyron and you put it on Cuusoo instead of this one. Both are like.. perfected nonetheless..

Henry Bolton said...

Woah! The starting process of producing it's machine to make it move is already complicated to work on. I do admire your passion for coming up with and creating various mini versions of automobile. I'm just in awe on how much patience you're putting in it just to make it exactly look like the original one. Will be expecting more from you then, in the future.

Dear Sheepo,

I am a huge fan of your LEGO Technic cars, especially the Porsche 911. I was wondering if you could give me some pointers, I have been have some trouble with the front suspension, I don't have any of those special ball joint connectors and I need to know of a good replace mend and design, and I need help with a good rear axle and gearbox, you see, I have only 1 1/2 u-joints and I don't have any of those gear pieces need for the gear box. I need to know a replacement for the 3 part gear piece.

Thanks for being my LEGO Technic HERO,
Dolan Stepniewski

Sheepo, podrías darme algo de información sobre el velocímetro? He visto algunos en Internet pero son muy grandes y poco integrables. Si hay algún link o algún sitio donde se explique me podrías pasar un enlace? Gracias por adelantado, y perdón si se explica en los comentarios no lo he visto por ninguna parte.

Sheepo said...

Este coche no tiene velocímetro...

Anonymous said...

Entonces, que es eso de indicador de velocidad? (speed indicator)

Sheepo said...

Indicador de velocidad engranada o indicador de marcha...

Vale ahora lo entiendo gracias fallo tonto por mi parte

what is the price of this car

John Li said...

Hey. so I've been searching for the wheels that you have used on your porsche. I was wondering where you got them from because I couldn't find them on bricklink. Would there happen to be any specific NAME for the wheel? I could not find any other 81.6 mm wheels except for the bike wheels which are too thin, or the balloon tires

Sheepo said...

The wheels are from 8448 Lego set.
