@Didumos69 you said.. But maybe for the contest I should...? I would because competition is tight and some models have all your features and then some !!!. Great job on your moc!!! good luck!!

@Go-Kart Thank you and good idea on the upper links, the lower part needs a major re-design.. I forget there is a trunk up front!!! This is my first supercar moc!! and its a mini!!! Well , I've done again!!! the best gets better!!! I've redone the rear suspension and Wow!! Floating differential ain't that bad!!! My design fixes most issues other users designers couldn't resolved .. this design have less parts count , a cradle over the diff so it doesn't separate under torque and 15 wide with the Corvette tires on!! it haves a 2 stud travel over bumps and it mimics a full independent suspension .. in a itsy bitsy space ....... (drum roll) ver 4.0 rear suspension !!! (applaud) Lego Technic floating differential by victormendoza_jr, on Flickr

Yes and thank you @Seasider and my parts came in so I hid some content.. :) Pi (3.142) was used in designing the Porsche and using the same concept , I was successfully able to re-create the classics look and a sneak preview of the body........

note: the 50/50 split is for rough weather driving while 20/80 is for high speed

When is it due?????? The deadline date is Monday, the 18th of May 2020 . @Seasider The original PSK design by Porsche features 13 clutch plates that substitutes the center differential and located near the front diff for weight distribution. The clutches provides the driver to program between 4 different torque distribution settings like 50/50 front/rear torque split , 40/60, 30/70? and 20/80.. the 20/80 front/rear torque split, the whole system is "unlocked" while 50/50 is considered locked diffs.. On my model, the 2 pairs of clutches , the first pair of two is connected to the rear diff and the second pair is connected to the front diff.. im re-designing the PSK on my model to a simple PSK after testing the dual clutches for the last few days the results were mixed but the clutches did act like a center diff .. the issue is that i needed a clutch lock so both sets of clutches are locked for a true 50/50 split.. more on that later when I introduced the simple PSK method.. thank you for that important question.. :)

Here are the required upper chassis picture without body for the contest requirements and it took me all week to designed the ultimate PSK under Studio 2.0 and the outcome is that it required the Powered Up system and programming the PU motors to engage/disengaged the locks from the built in sensors on the Powered Up. maybe the angle tilt sensor on the Powered Up can be used to optimized the clutches when you go in fast into a curve and the body rolls is compensated via the motors/clutch and software!!!!!! first concept of this idea needs to be done latter.. using a mini model is to small and the contest doesn't allow any electronics.. The following images is for size reference and may not be the final build. Note: the springs on the front axles act like a link !!!

and here is mine!! and the tires are just for mount and will not be included on final build Lego Technic Porsche 959 by victormendoza_jr, on Flickr

@letsbuild To be honest, I have a handful of broken black and blue pin but those don't count!!! :) LBG of all sorts had honorable mentions due to my Technic madness

Building style.. the way Technic is built ..... Almost the same suspension as in how its built??? maybe and the front suspension type that Lego haven't used in a set in a while..

and the programming!! Please!! like a quick look at your code blocks for verification!!!! :)

I don't know if this subject was ever brought up.. Is it me or paave's LEGO Art from YouTube video of his muscle car from a few years ago has a very similar style of build even though its on a smaller scale... of a muscle car.. its almost the same at some areas.. Great designer overall!!!....

If you asked me.... Black is Lego Technic gifted child... It is lighter in weight and its stronger then the rest.. have you ever broke a black color element?? impossible!!!! JUST SHARING my view points ....

Porsche 959 PSK Porsche-SteuerKupplung The command clutch, when I first started building my moc, I wanted to have features on my model that the real Porsche 959 posses. The AWD was the most challenging since it was using concepts with clutches that I don't think if Lego technics can reproduce .. The idea is that the output of the transmission can be split and be user control (4 different settings) between the front and rear axles. The center diff was replaced with clutch plates (13 total) and on my model , I have just added a 4 plate setup with 2 plates goes to the front diff and the second set of plates goes to the rear diff.. I I took one plate off from the front diff and moved it to the rear , then the output would be 25% front and 75 percent rear. so a 50/50 split is good since its one of the 4 PSK settings.. The only issue im having is it really necessary to add this feature in the moc since it adds friction to the drive train when you want to push it around!!!???? i worked on this for many days... and I even manage to squeeze a working 4 plate setup.. well I also done a front end concept and I even took a outdoor picture a night and took a picture of the Mars, Jupiter ,Saturn and Pluto conjunction with my model in the picture!!!

I believe you can do 3 colors in full with his current style. Full dark azure, white and orange!!!

That's the one only issue I don't like about the Lego Power Functions cables.. I Bought a brand new PF large Lego motor just recently and my first run across the back yard on.., the battery pack bounced off the chassis and yank a few motors off the chassis and my Large pf motor, the cable got entangled around the differential and I carefully pulled out the cable and where the 20 tooth gear and the 28 tooth on the diff left their bite marks across the cable. If your lucky , you can pinch it the PF cable as you have it plugged in and turned on.Start from one end of the pf cable and use your fingers and follow the cable and smooth it out on the table and you might get lucky and you'll find the damage on the cable..

@Go-Kart One of the Technic challenges is to design and build the wheel!! where your wheel doesn't slide off the axle and/or the axle doesn't slide off the wheel. most Lego Technic wheels have two side like a coin, heads and tails or on a wheel... positive or negative rim offset. On my diagram (studio 2.0) the 3 yellow color wheels the center wheel is negative and the two outer are positive .and when it comes all the math and angles, just having the wheels on either or offset , the positive side of the wheel can save you 1 or 2 studs of length and the pros and cons varies when other factors like king pin inclination , tire scrub ,ect ect .. but for now its about the axles.. on my diagram .. which you can barely see the female end of the cv joint, the cv axle joint is a friction less which cause axles of all sorts to easily slide right off.. goes against rule two, axles can't slide out.. Axles with stops comes in very handy. a few example are shown. On this contest , i need to use the brown colored axle with stop with the 47mm ?? corvette tires in order to be 15 wide complaint . Ideally using the parts @I_Igor recommended provides the best anti slide designs but urges the desired length . Lego technic the more you know , the better you"ll be off by victormendoza_jr, on Flickr

Hummmm... Now I know how the 959 AWD system operates. The front differential, which distributes the power it receives to the wheels, has been modified in such a way as to make the classical third longitudinal differential unnecessary. The job of distributing the movement equally between the front andrear axles is in fact taken over by a brand new clutch called the "PSK", which stands for Porsche-SteuerKupplung, i.e. Porsche command clutch. It is a particularly interesting component, as its structure allows direct control of its working. It consists of 13 plates, seven outer and six inner, in an oil bath, with modifiable reciprocal slippage ... well, i guess I need to modified my drive train and chassis . I would like to add this to my model if possible!! and if you're interested.. a copy of the real Porsche 959 owners manual!!!! https://drive.google.com/file/d/1385IKExVUAxTp19HZyF1tTIGaYrm-AKb/view?usp=sharing

@keymaker.. because its 1:40 past midnight!!! and our eyes hurt during the daytime.. I'll start producing brighter pictures.. cause I just like the "dark theme"

I heard and listen fellow fans!! Version 3.0 Rear chassis!!! The best just gets better... I was able to integrate the new differential to the latest build and still got my independent suspension (swing axle) and wide tire compliant but just in case ill submit the corvette tires for the contest ... 2 speed Hi/Low transmission matted to a twin turbo flat 6 with real pistons,fan and valve rockers on the head just like a real petrol engine!!! Center diff that distributes 50/50 power to the rear and front new 5 geared differential .. more to come .. and like the real Porsche 959, this MOC has been ground breaking with so much tech per squared inch!!!

@jorgeopesi. Thank you.. "Push" is different then RC!!! I actually need to push more often.. and its an AWD with center and a locked diff is no different then my setup.. its called positraction.!! but I do plan for the model to be enjoyable .. Building new chassis..

@jorgeopesi... I understand on how you feel... I even posted help regarding the subject.. First of all, the scale is way off with a standard differential.. If i was building a super car at 1/8 the scale then your argument is valid but at this small scale, the standard diff is way to big.. like clown big feet bad!! I can fit the standard diff and still keep the transmission but now we are like the 42093 Corvette with small tires.. .. lose the suspension.. then i can use the bigger tires... if you look at the tech, and you haven't seen the body.. (it is gorgeous) ..the tech will blow you away.. if you look at the body.. its a plus.. what ???no diff!!!!.... .. i would think having a piston in a fake motor is important or otherwise you're teaching people that a rotor/Wankel motors is the mainstream?? I've built RC at this scale with diffs and not.. not much difference since now your working with a small scale.. can you please tell me how the new diff is better then the old diff when friction is higher on the new diff.. so even using a new diff at this scale is worse since it didn't react quick enough compared to the old diff... I'm just sharing my experience. can you share yours?? thank you and votes are not important if you were building this for the fans and lovers of technic.. my reward was a fan based mod that was inspired from my moc !!! that was shared to me and it looked great.. and I didn't even finished mine.. :) ..

and a quick video on how the transmission operates

Porsche 959 engine, transmission and rear suspension update. The Porsche 959 uses a 6 speed manual transmission and the first gear is actually Low 4wd gear and 2 to 6 is 4wd high gear. On my model , I implemented a low and high 4wd gear (2 speed) installed behind fake engine. From the transmission the power goes to a new style center differential marking this another first for Lego Technic brick kind. I'm just racking up many first designs and builds for this MOC!!! from the center diff, power is distributed between the front and rear simple diffs... Im using simple diffs, due to wanting to have bigger tires on my MOC!! please post any comments.
