Bloody hell you go deep but I have been a mechanic for over 30 years and I love it. Every day is a school day and I love learning things. I know its not for everyone as its not instant gratification that everyone wants now days but this is a proper great video. I would like to meet you one day and just talk cars for a couple of hours.
Very deep alright 👌
I'd like to see every little detail of the build, start to finish, with all the explanation and chat that goes with it. The explanation of cylinder cross hatching just blew my mind!
Best maths lesson I've ever had... Probably a damning indictment of our education system but still weirdly enjoyed it and might have paid more attention in school if it was like this.
😂😂
Being a geek and a scientist, please go as deep as you can. Bloody brilliant
Thank you!
I like the guy doing the vinyl work on the office window 😂😂😂
Ha ha yeah Jord doing his thing!
Your going deep into details now ......and i love it.....and i know nothing about engines!
Glad you enjoy it!
The reason I keep coming back it’s all in the detail top notch no pun intended 🙄
Thank you!
Loving these techy videos, really interesting to see what it takes to prep/build engines to a high standard. A engine rebuild on say your rb25det in the skyline from start to finish would be cool (If only because i'm wanting to do mine) and would be nice to see your take on those types of engines.
Where do you see the future of the business going? In terms of where you’d like it to go, the world of electric cars, the decline of R8s and how that makes you think business planning wise? Love the balls you have to go and do this stuff whilst planning for the future 👍👌🏼
you are clearly a very experianced man with engine building and the v10 engine and gearbox stuff,
i admire your passion for detail and your craft
,the sad fact is so many of these have a go heros and mechanical fools have 100.000 of subscribers
which saddens me but shows the inteligence level of the masses that watch you tube and put these amature mechanics at best, on there
pedastools and make them self proclamed experts in bullshit,
people seem to love the performace builds ,maybe more of this,
i work with a rotory specialist and like you we found a nich and just do what we do with several cover cars back in the day and fastest drag rx7 in uk and europe back in the day,
i feel bullshit gets views sadly but respect to your aproach and your brains are clear to see ,respect,
Yeah we battle “what we want to do” vs “what we think would be popular”
It’s a hard one, hopefully people just enjoy what we get up to!!
Lovin the torch action for the monitor.
Big bang theory is amazing. I have watched everyone at least 5 times. Another great one is Brookland 99
Yes Ricky !
Its this kind of video that makes me watch your channel, facinating detail. It's not for some i know, but don't stop doing them. The end to end engine build feature should be your Noble engine.
Thank you for watching. It’s really appreciated.
Ricky is an expert on reinforcement of bottom ends...
Pure gold Rick, more, more, more please! Cheers, Doug
Thank you
That was so interesting Ricky. Having to pull that explanation out of your Snap On Bobble Hat was mind bending! Seriously though although you are pretty humble in saying there are loads of others out there who are better at building engines with much higher levels of sophistication, other than formula one, I'd be very happy for you to build a race engine for me if I were in the position to commission one( I'm not I'm a 70 yo ex mobile mechanic lol) Your enthusiasm shines through in your videos and Davla brings out the best in you! Keep the vids coming, the format in these technical videos is just right. As for your other ones, sorry I get bored looking round your car park to see if whatsisname's motor has arrived or gone. But when you get in the workshop that's a different kettle of pistons!
Appreciate that, and thank you for watching
I use a drill with a paint stirrer with rag and sandpaper wrapped around it. Using my eye-ometer it looks mint every time.
😂😂
OMG, this is incredible - thank you :)
Glad you liked it. Thank you for watching.
Totally fascinating. Never seen anything like it.
Thank you for watching.
Keep up the good work.
Thank you
Just at the point you were saying your head was hurting, I was thinking how well you just explained such an exotic bit of engineering to a non engineer. Love your work 👍 0:30
Thank you
Now that was a video! My poor little brain was in geek-out mode, possibilities / how-to's on the hatching ...what a bunch of variables to play with. And it's only really possible with this sort of kit. When I was a lad (maintaining me 80s 2T crosser) and tolerances were not what they are in modern engines, we'd get a rebored and honed cylinder back from the 'machine shop' at say 10thou oversized. After the first ruin-in session down the local track we would be back in there to make sure the piston looked and "felt" smooth up and down the bore - if it needed fettlin' a flap wheel in my dad's old Bosch wasn't unheard of 😳
Different times...
Can’t beat drill hones 😂
Ricky love the total breakdown of crosshatch engineering and performance to your field of 4 stroke engines, does this apply to 2 stroke engines?
Great vlog bud...
Cracking vlog very interesting, having built a few of my own cars and motorbike engines never thought about the honed bores or why they were done like that 🙄
Great level of detail, must be really good for satisfying any customer service issues and for customer confidence.
That’s the whole point of our channel, so clients can see how we do things!
This is so interesting and Ricky is great at explaining complex things in a simple way. The fundamental ideas in manageable way across all different engine disciplines. This is the kind of experience, understanding and level of detail that a customer at this level expects. 👍
I love the way Ricky starts explaining something and then realises he's into another level and either backtracks or 'breaks off' to explain the next level before he gets back to the main point, can soo relate, even two or three levels in😅
Glad you enjoyed it!
Interesting. Wish I could justify all these tools for my one build every 1-5 years!
😂😂
Fantastic as always rick could you do something on blue printing and benefits of it please
Hi Kate. I always wondered why about cross hatch now i know gg Ricky Fascinating
m/s, units for uppy-downy honing linear motion 😁.
Great video 👍
Full engine build please!
Ricky-Have you thought about a fixture that clamps against linersidesand in the middle is another clamp which swivelsthat holds the camera ? This would eliminate holding the camera my hand and rotate the camera to different areas.
This content is 👌
Thank you
Wow I never even imagined what goes into building an engine. Been a car guy im a bit embarrassed to say that lol.
Mad with all the technology around they can’t just make engine parts the exact same weight and size out the factory.
Bedankt
Thank you 🙏🏼
Thanks
Thank you.
@@REPerformanceUK I just watch your videos and the complexity of the engines, and think what are we going to lose, over over a period of years, if we adopt totally electric engines.
I had also never considered the angle of honing an engine board and how it would make a difference. You bring a new light to my world. LOL
Great video, the techie ones are the best! How much of the build process would you say is commercially sensitive? Your conpetitive advantage so to say?
Amazing footage. Really enjoyed it all. Would F1 engines use this technoligy? Noticed your subscribers have jumped up, well done, hopefully at a 100k soon.
Brilliant explanation, I'm no engine builder or even mechanic, but you explained that perfectly.
So what do you advise a home builder to do on honing? Say Zetec or pinto? 😂
Think it would be a great series to do 80’s hot hatch engine builds to see what modern technologies can get out of them. 😮
Yeah me and Dav are always chatting about what projects would go down well on the channel!
I’d love to see development work, playing with spec ect and what the results are on the dyno
So as you approach tdc or bdc when honing, the machine is capable of reducing hone pressure to provide a consistent groove depth. Can I just say Ricky, your explanations calm my ocd mind. 👍👊❤️🏴 Hi Kate. 👋x
just wow. i think i grasped it but i know i won't retain 😭
A start to finish engine build and map would be nice, inc how you set up the dyno, a proper idiots guide, the details to honing angles are a whole new detail I had never considered,
Would this be an example of a Quali engine in the old F1 days? all the power but wont last.
Professor Ricky made another great video! Ricky, I saw in the past someone in a workshop abroad that was rebuilding an engine and put only one cylinder liner and did not put liners to all the other cylinders - I believe that the right way is that if there is a decision made to put cylinder liners to an engine to fix any bore scoring that all the cylinders need to be fit with cylinder liners and not just 1 cylinder, is that right?
You can now link this information into runing the engine in , ie bedding the rings in to the cylinder bores ??
Great vid, do like the tech ones.
I do have a question, is there a common cause for ringland failures? The marque of car i have appears to suffer from these failures be it standard low mileage engines to tuned engines
Really enjoy these build vids and I never knew how much detail goes in to building an engine. With regards to the cross hatching in the liner, what would happen if it was more of a mirror polished finish? Wouldn't that give both good compression and oil run off with less friction?
That would mean there was no oil on the cylinder wall so you’d be getting metal-to-metal contact between the rings and bore which would result in a lot of wear. You need some oil but not too much which is why it’s a balancing act between compression and oil run off.
Is that VR46 at santa pod on the background of the computer screen? 😂
Ricky - surely the golf r engine for the noble is a good candidate for an in depth, full build video? I enjoy the higher end builds, but I assume the more attainable engines generate a lot more views and interest from a wider audience?
Yeah I think it will be too! Especially as we are putting a super trick head on it!
A very interesting video, having been a Mechanical Design Eng. now retired, also involved with racing Bikes, Cars and Supertrucks over decades.
During the Design and Manufacturing process, where surface finish of bores for Compressors was always a contentious issue, this level of Measuring Kit, Software and recording of data is outstanding. It gives the engine builder a font of knowledge as to the size and surface finish which then can be analysed to find the best requirements for performance and life of the components.
As an aside, are the Bores 'Plateau Honed' as aa process to minimise Honing swarf?
Keep up the good work, keeps me interested in the engineering side of motorsport.
Best regards
Thank you!
What about laser structuring as a finish to cylinder bore?
Just goes to show, honing is not boring🤔😂
Long gone are the days when you'd run a honing tool up and down the bores using a hand drill - run your fingernail up and down the bore and say "yep, that'll do", been guilty of that when rebuilding my golf 16v engine 20 years ago.
Absolutely fascinating.
Watching this, I was struck by the contrast between this level of technology against another TH-cam favourite of mine, Allen Millyard. Check him out, he builds amazing engines in his shed with very basic tools.
I reckon for you guys to visit Allen, and vice versa would make a really interesting video.
Yeah I know Allen’s work!! 🙌🏼
How does the angle effect the power and wear rate on piston rings.. Would you not want to have more circular grooves than vertical honing to increase power? Does the honing wear out and power go up?
At the risk of damage due to oil starvation in cylinder? So many questions
If you want a minimal cylinder engine build from start to finish…. do you fancy doing the speck miata build we talked about?
OK, sorry, big tech vid, lots of points to raise. The most relative vid is trouble shooting. We love riding/driving but when the machine goes wrong, that's where the biggest challenge is. How do we get back to good...reliable...fun.....build is a base point. Unfortunately, it's a way of maximising fun before fixing creeps in...so you, RE P, stay in a job we love you for x
Rick and Dav, How many hours go into a V10 engine build when you crack on? (no filming)
Wow, really impressed! Knew the different stuff but not to the extent! Why dnt u build your own bike engines? Is it because u can earn more money doing your jobs so let someone else do your engines? Really impressed by how meticulous you are 👍
Is the next step for Rick to get a close control AC system in the engine build room to keep the temp at a constant so all measurements are made at the same temperature?
It’s air conditioned anyway mate!
had to watch this twice to try and wrap my head around the explanation…. my head hurts more wrapping my head around it than you probably did explaining it… what happened to Suck, compress, explode, exhaust?
Where can I find ur hats
Would it be possible to bolt a torque plate to the cylinder head and take the honing machine up beyond the bore to reverse direction, to give a more uniform finish in the swept area?
Theres a guy has a channel on exactly this, theres material removed during boring that reduces the cylinder size so when machining bires they torque plate them and compensate for the micro amount of material removal that occurs during honing, i think the channel is called something something piston rings but theres a level up or four from this level of detail!
How much does the cross hatch angle change at T.D.C and B.D.C ? And does the hone machine compensate?
If the linear and rotational movement are synchronised (mechanically or otherwise) it shouldn't change.
Couldn't see hats on the website yet?? Are you planning on showing wearing one next video??
Yes hopefully next week
Getting a McLaren in the spring if the engine goes wrong I’ve decided not to do it myself..it will be down to you Ricky to fix👍🤣..
Not wanting to put you off but I'm on my 3rd McLaren. It will almost certainly go wrong. My current 600lt spider has developed a "feature" where if it rains or gets slightly wet, both windows drop fully down.
@@mcnelstv1880 got to admit I’m a bit nervous on the reliability..thought id buy through Thorney Motorsport.
@@oneeleven9832 John Thorney is a good guy. He made me an exhaust and did a couple of services for me, no complaints.
Nearly 40 minutes of two blocks in a quiet room talking about FUN WITH FLAGS 😲😲 and the long and short strokes and just for a little family viewing Man Gravy and for some extra stimulation A photograph of himself as the background on the computer @$$#_@ locally the algorithm missed me in relation to the 40 minutes of liner's..... From what can only be described as a garden gnome 😜
😂😂
i thought engine building rooms should be spotless? what if a bit of fluff from yer hat got into the engine? besides this school boy error i look forward to the next vid.could you please wear a lint free cap instead.
one of those school swimming hats like a big condom
Then you would need your buy a bunch of liners measure them all and use the ones closest to each other.
Stupid question , do piston rings affect the cross hatch .meaning the thickness of the rings. From manufacturer to manufacturer meaning piston A has a certain ring thickness and piston B has a different thickness ring
Or are all rings regardless the manufacturer all say 2.25mm thick
Or am I talking shite which I probably am 😂😂😂
People and mainly males love lego.. we/ they enjoy things going together, puzzles, jigsaws. this is why we enjoy the tech stuff and building/ stripping. pole dance for all.
Question:26 mins in, what is Jordan doing on the glass?
I’ve no idea, but I ‘had’ to go back and look.
Sometimes i use the window as a peel board to remove backing material from PPF 🤙
@@pro-detailuk6608 I was hoping you were sticking a rude insult on the window and seeing how long before Ricky noticed🤣
To let everyone know how smooth the finish is on the liners are. If you were to shrink the earth to the size of a pool ball. The earth would be smoother. Physicist Neil Degrasse explains it better than me.
If your paying a company to hone and cross hatch, wouldnt you expect them to supply the relevant data with each liner?
Not to this level no.
So ...
Got to say you know your shit about engine un real
But......not each cylinder has the same position in a block.........
Froome
Epic picture of self at a drag strip is very distracting while talking about scoring bores of 1700 strokes per min cylinders..........😊
