In this latest episode of Tyrrell’s Classic Workshop, Iain delves deep into the ongoing restoration of a Bentley S2, a project that has captivated our audience in previous Tyrrell’s Classic Workshop videos.

    This episode offers a fascinating exploration of how Rolls-Royce and Bentley, once operating as a single entity, ingeniously adapted the Bentley S2, originally designed for a straight-six configuration, to accommodate a massive V8 engine.

    With the engine out, Iain he reveals the robust chassis-frame of the Bentley S2, offering viewers a rare glimpse into the car’s construction and delves into the rich lineage it shares with the Rolls-Royce Silver Cloud series.

    Furthermore, Iain explores some of the intricacies of the steering mechanism, ingeniously designed to fit into the limited space of the Bentley S2 once the V8 engine had been added. He also provides insights into the car’s complex heating and ventilation system, which, despite its cumbersome nature, is an integral part of the vehicle’s unique character.

    This episode is a treasure trove of information for classic car enthusiasts and admirers of the Bentley S-series and Rolls-Royce Silver Cloud series. Iain’s expertise shines as he takes us through each step of the restoration, bringing us closer to the reinvigoration of this majestic vehicle.

    1. Crikey Iain ! I thougt l was going to write my usual praises (which l will of course !) But l actually and hopefully gave sound advise to derin 111 who seems to be a very lonely and frustrated gentleman …… Good evening lain . I diid wonder if we would ever see this classic in a more graphic setting …my goodness , you've really got a move on . Would fitting a modern and compact air conditioning system be food for thought ? Until you mentioned the emotional connection to this wonderful motor car l was going to suggest fitting the original single headlamp wings , so elegant on a Bentley . And you've instantly quashed those nay sayers who claim this V8 to be a copy cat of the Chevrolet engines of that period . They may have been an inspiration , but that is all . Back in 1973 when l was an apprentice panelbeater ( crash repair ) at South Devon Garages , the premier main dealer in Torbay. l had the choice of a 1970 Triumph 2.5 pi mk2 saloon or a Bentley S2 for the princely sum of £695 pounds …..l chose the Triumph ……..only because the Bentley was Mason's Black over a very garish bright yellow ! Hindsight ! Thankyou lain. P.S. Will we ever see that Jensen in more detail ? I had one in the late 1980's . What a car ! 💕

    2. Dr Ulrich Einhorn wrote a piece on this engine which was very interesting to read. As he was(is?) Bentley's board member for engineering he knows about these things. He wrote that exactly that early design made it very adaptable for turbocharging in later iterations. Version of this very engine was used in the Mulsanne until they dropped it. He claims that the final version with turbos, fuel injection and ecu, the newest version would have been able to idle on the stuff that came out of the exhaust of the S2. Talk about increase in engine efficiency.

    3. Love your video's especially on RR and Jaguar, I Have owned a Bentley S3 for 6 or 7 years now and drive it as often as possible but the complexity I find unnecessary and would love to modify it with rack & pinion steering and disc brakes but the car drives so well (like no other) that I leave well alone. If it breaks I might do the mods.

    4. I enjoyed your earlier video when you were driving the car and was a little shocked to see it all apart. I guess that I shouldn't be – something like this needs to be properly attended to. I like to fiddle with my vehicles but kind of stop when removing a fender is necessary! (or both for that matter). i'd lvoe to have a Bentley one day although I haven't seen any for sale that have had proper maintenance (cheap tires are a dead giveaway).

    5. 11:44 How my heart sank when I saw that the spark plugs are directly below the exhaust manifold… Wonder what special tool was called for there? Had a girlfriend with a Z28 Camaro…boy, the engine had to come off its mountings in order to change those spark plugs!

    6. 14:05 that transmission unit wasnt the first time they were embarassed by GM by the way, when they were updating the Corniece or the silver shadow, they ran and updated their testing in a windtunnel and with proper sound sensors to detect just how much vibration and road noise was coming into the cabin

      and they found that, a 1973 Chevy Caprice Custom, actually had better sound insulation and dampening than what they had

      and that came straight from one of the classic rolls royce mags in the UK when they were talking with some of the old school development team from back then

      and FYI the way it made it sound in the mag was that the TH350 and 400 series transmissions were smoother than the GM units in the rollers

      but after awhile they wore and just lost their smoothness, which sadly wouldnt be un GM like

      given their development philosophy's that came about in the late 60's, like the engines and transmissions from before then were actually top notch

      like if you ever get the chance to look at a 59 to 61 turboglide, its basically a Koneigsegg Regeria transmission in 1961 with three turbines running at the same time and its absolutely smooth'

      but it did have problems in 59 and 60 that they had to work on, but once it was honed, 40 years latter and my pops still talks about it, and honestly sadly just like the far better 263/283/327 series of engines

      vs that 350 they shoved into everything with sub par rods that werent anywhere near what that engine was capable of unless you paid extra to get what you should have had as standard

      I think GM just discontinued it and went cheaper to save on costs thus resulting in the TH series we have now that's gone on for what feels like 80 years

      and also theirs shift kits for the magnets, as the shift points on those, atleast in the 70's were controled that way that should help with the RPMS but I would imagine rolls royce has their own set for that

      heck maybe the magnets just corroded now that I think of it, like maybe put some anti seize in it and some dialactic grease

      and see if it makes it run smoother, as you gotta figure, rolls royce, wet weather, its a GM part so you dont think it needs to be looked at, could be that somethings stuck or come loose

      or just flat out needs a clean

      although not the motor, your right about leaving that alone, as the parts all wear in in a system, its why on old cars one of the worst things you can do is just throw old parts at it that are worn completely differently from each other

      and then you wonder why it never runs right

    7. We had two of these as wedding cars in the early 80's in Sydney. I took my kids to the drive in movies in one of them and you should have seen the looks I got !!

    8. Wow my father would be so proud of the care, consideration and effort you and the team have put into her. She will undoubtedly bring so much pleasure and smiles for generations to come. I cannot believe nearly 50,000 view, you’ve an amazing group of followers. Do you thing we can see some stages of the body work? Single layer metallics created a lot of additional work when using modern paint materials. 😮Thanks again.

    9. I would put a modern American L6V8 with Air conditioner , Wildwood brakes and modern heating.
      Box up the original stuff.
      And have an awesome design with dependable internals.

    10. Marvellous to see a beautiful old lady being given the love and respect she deserves. Not that I have ever owned one, but I have always preferred the Bentley to the Rolls Royce, perhaps because of the racing heritage. Goodness only knows what the restoration costs are but thank God for these wonderful owners and the companies like this that keep our heritage running. Long may they reign,.
      Thanks Iain for another great video. Cheers, Bob

    11. Nice one Iain,In the 1967 film Robbery there,s a clip of Stanley Baker driving his S3 down the M4 towards Heathrow with the speedo needle at a steady 90mph.I recall that was the year the 70mph limit was made permanent!

    12. I’m just a fat American as Mr Clarkson puts it but I love every nerdy video you put out, I love to learn things about machines that I don’t know and you are an excellent teacher, thanks!

    13. Thank you. No surprise about the geared camshaft drive. Lottie the Tank Whisperer has released a series of Meteor engine rebuild videos in the last few weeks. That heater is massive.

    14. I really enjoyed a technical dive into the inner workings of a vehicle that I'm not particularly familiar with. It's always fun to see how companies from various countries and periods of time approached the many facets of building an automobile.

    15. The best, best car videos are from you! Really appreciate your great work. So different from mainstream car reviews that flooding the utube. Your channel is a #1 form me.

    16. I was having a strange feeling watching these old beautiful "ladies" you Sir showed here, thinking that the love men have for their cars is so strong that could possibly be taken over to future lives or incarnations. I really love cars from this era, maybe I had one in other previous voyage on this planet…

    17. Every time I hear the intro I get the same level of excitement as a child might get when they hear the voice of a beloved distance relative who’s arrived for the holidays! 😊. I am ALL about the high performance hoopla of screaming engine and burning tires, but Iain’s videos of these grand ol’ classics has inspired the exact same enthusiasm in me. Thank you, Iain for sharing your passion and knowledge in these videos for all of us to enjoy. Happy Christmas, sir!!

    18. I prefer his presentations, so informative and his delivery is better than some overpaid TV presenters.
      My initials are P & R. When signing with pen on paper, even from a young age, as was my love of automotive engineering, I interlock them similar to Rolce Royce. A piece of useless information for you.

    19. Heating system: this small, subtile piece of equipment here…..I just love this British humor and understatements. Thank you for another very informative and nicely presented video.
