Love this type of content. Ricky never ceases to amaze with his knowledge. These are parts of the car the majority of us never get to see. Thanks guys. Really interesting.
Glad you like them! 👍🏼
Another great tutorial. Explained in simple engineering terms. Love the vids! I learn lots from them.
Thank you I’m glad you like them!
Brilliant Ricky, I used to build ship deck machinery for the navy and that explanation made perfect sense. Basically if i wanted to move my diff in 0.2mm i would take 0.1mm off the top shim and add 0.1mm to the bottom as long as it coincides with the squish settings. I used to work with worm shafts and gears and we always wanted a kidney shaped marking blue mark on the worm wheels. This gave the best results for oil feed in and exit.
Keep up the good work, I love the tech stuff.
Thank you! Glad you like them!
Loving this type of content. Everyone can unscrew some bolts.. (almost)
Sharing your knowledge and the amount of details you share on the board is much needed!
Thanks from Denmark 🇩🇰
I appreciate that! Thanks for watching.
Great Video Ricky ! Really feel like you’re in your element with this type of content it’s great to watch
Yeah I like the geeky stuff! Thank you!
I love these tech videos, a DL800 tear down video is what got me on this channel and as an apprentice tech who loves supercars this kinda video is awesome and inspiring. Keep it up!
You are my idea of a British Engineer you can see why we are or were the BEST Cheers Rik.
McLaren have always been open diff havent they untill the artura
That's my understanding too. They individually brake the wheels to simulate a limited slip diff. I wonder if the wavetrack is going to confuse the traction software
@@RedBatRacing possibly, although I'd imagine it has to be reactive to slip, so if it doesn't see enough slip thanks to the diff it shouldn't do it
@@RedBatRacing It will cause issues. I've seen people complain of nearly crashing after installing an LSD.
@@stefanroseEP3 it will also manage torque to each wheel, not just detect wheel slip. I'd imagine the software will be looking at steering angle, engine torque, speed and maybe even g forces to calculate the optimal torque split. The wave wavetrack does similar things because it's also a variable torque split. I'm just guessing, but I can imagine the two working together will tram line the car out of a corner when you don't want it to
We have already started logging cars at a canbus level to understand how the electronics work to control slip!
But yes we are aware changing the diff will create issues, but we are already looking at the stability programme parameters to tune the control just like we do on the engines and gearboxes.
Luckily we have people like @emf to bounce ideas off!! 👍🏼
Very well explained, your tech vids are very good.
Thank you!
In the 80's used to re build cortina mk 4 diffs all the time at ford dealerships...never had someone explain this on my youtube followers...takes me back ..cheers..👍
Interesting, professional and funny as always 👍👍
Thank you! 🤪
Love it. Makes total sense
Thank you!
Love the whiteboard work - even when it is inaccurate/wacky/insufficient it still adds value if the consumer *thinks* a little bit... I struggled with the initial description until I realised that there would be (a now obvious) overlap between the crown wheel and pinion... in my defence I do more stuff with bicycles that don't tend to have complex torque diverters...
Brilliant as always :)
Love it - and a free table too 👍
Hahahaha 👍🏼
Fascinating mate the technology and the thought that's put into these machines 👍
Yeah they are mega!
Love it ❤ I love watching your videos 🎉
Thank you so much. Glad you enjoy them
Great content Ricky 👍🏻
Thank you Phil!
Fantastic content - really enjoyed watching & with white board content 👍
Glad you enjoyed it! Thank you
If all schools had teachers like you !!!!!!!! 😎😎
Now we are talking, great video thanks Ricky.
Thank you!
Love these tutorials moments...had to brew up when I saw the whiteboard enter stage right 🤣🤣
Hahaha glad you enjoyed it!
Every day is a school day! 👏👏👏
If you can fix / upgrade McLaren gearboxes work will abound. At times they have even struggled to supply warranty replacements. Great to see the McLaren aftermarket come of age.
That’s the plan mate, same as what we do with the Huracan and R8 gearboxes!
@@REPerformanceUK Excellent. McLarens are good value at the moment. They need good aftermarket independent service to make them affordable and reliable for the long haul.
@@Gorbyrev yeah I agree!
Well explained fella 👍👍
Thank you!
Good explanation of the pinion adjustment though
Thank you!
The McLaren 570S has an open diff. They use braking of the inside rear wheel to help turn in.
That’s right mate!
Such a boring subject ..but you make it interesting ...great channel..
Thank you!
Love your knowledge. Every time you go to explain the science/engineering on the white board you should put on a white lab coat. 😂
That’s a great idea! Thank you!
What’s your thoughts on the Litchfield Motors LSD “Our solution is the development of a new mechanical LSD which is similar in design to those fitted to Mclaren GT3 race cars”.
I’ve not seen it to be honest mate, probably similar to our plans with an aftermarket diff like a Quaiffe etc.
The GT3 cars don’t use an Oerlikon box and they are manual so a completely different diff and transaxle setup.
Any recommendations on motorsport or mechanical engineering jobs or courses to learn these sort of things. Been out of an mechanic apprenticeship the last year and looking to move to motorsport.
Looks at Oxford Uni for motorsport engineering course and contact local race teams. Start by volunteering on race weekends, show your value, understand the conditions and requirements then move in to being a number 2 mechanic all the way up to engineer!
An engineer has to be a people person though…..you are the gateway between the car setup and drivers head/ego et
While I don't have any personal experience putting a LSD in these transmissions, I've heard of people nearly crashing because of the car rapidly changing direction after installing an LSD. The software in the car isn't expecting it to act differently and compensates to fix it, causing an unpredictable result.
Got to test it as I can’t see how reducing the differential across axle would cause more issues? But we will test it on track mate! We are already datalogging the stability programme parameters with our canbus sniffer.
@@REPerformanceUK There are a few videos of McLaren owners adding LSDs and almost crashing and dying. As EMF pointed out, the traction management software doesn't account for the presence of LSDs. All McLarens are open diff, and McLaren uses independent wheel braking (with varying force) to redirect torque to the wheel with traction. Torque typically travels to the path of least resistance, usually the wheel with less traction, thus creating the infamous 1-wheel burnouts on cars with open diffs. McLaren mitigates this problem by applying braking to the wheel with less traction to send that torque to the wheel with traction. When you introduce an LSD, the computer doesn't know how to behave and will apply the brakes to both wheels or the wheel with traction, which is not necessary, as they're both registering the same wheel speeds, thus creating very dangerous spins like in this video of a 765LT where an LSD was introduced. The 765LT was traveling on a straight road in this video. McLaren pioneered this technology in F1 to mitigate traction and help rotation with brake-steer. - th-cam.com/video/Xaq0Zc1TB0g/w-d-xo.html
@@REPerformanceUK if you want a mechanical diff for track, then your going to have to find a way to disable to the software diff, maybe you can get a race ECU? Otherwise the torque distribution across the rear axle is going to cause all sorts of understeer/oversteer issues.
@@RedBatRacing Yes that is out plan. We would need to optimise the stability programming to help get best use. The diff will just help lower slip across the axle on accel so we have been datalogging the stability programme to understand the parameters of when the "brake on spin" function activates. We do something similar on the bikes where we use the rear brake on accel to limit tyre slip.
@@DeeperImageAutomotive Yeah we know how the stability programme works for corner entry and how it uses the brakes to help slow the spinning wheel on exit (VWG have a similar concept on Gof GTI's etc) but we want to improve grip across the axle and remove the tendency for the inside wheel to spin off the apex. We have already started looking into the stability programming and have started data logging with our canbus sniff tool the parameters of the OEM system, the channels we can alter and under what conditions. Besides, it will save you money on discs and pads! lol Cheers for the detailed comment!
I thought you were going to flex you muscles and pick that box straight up!!!!!!!
What muscles? 😂😂
@@REPerformanceUK LOL
so, what was wrong with it ?
Is there any chance of seeing Rick do this stripdown and re-build on the bench ?
Yes we are planning to do more on the strip down Phil!
@@REPerformanceUK Thanks for the reply. Would be interesting to see the re-build if poss , all the pre -loads and backlash adjustments, shim measurements etc , (sorry being boring now).
You make me squirm when I see you putting trans parts on the ground, I think wave track and similar non mechanical LSDs are dangerous on alot of high power cars. The cause of sudden change of direction when change in tyre load occurs.
On the floor in a plastic bag? Why would that make you squirm? Everything has to be cleaned before it goes back together anyway!
RickyCAD
Thank you.
I love watching these videos until I get pissed off every time with not being able to hear what you are saying because of the windy gun going in the back ground! So I never get to see the whole video, it's just too annoying.
It’s a working workshop……clients cars come first! 👍🏼
Isn’t what he’s describing around getting “ gears ready “ McLarens pre cock not sure if that’s the right way of saying it lol 😑
What do you mean mate?
Y'all need some better production quality, steadier camera, multiple cameras, so the cam guy doesnt have to pan back and fourth between the trans and presenter, cant hear shit with that equipment running in the background.
That takes away the fun.
The point is it’s a working workshop and not a film studio.
Our engines our perfect not our filming! 😉😉👍🏼👍🏼
u boys need to stop all the mounting and laughing so dam much while ur mounting boxs
