Welcome back everyone! Video was removed for a couple of weeks after someone being super petty copyright struck it for using 25sec of their video as an explanation of the content of this video. RUclips have (quite rightly) agreed it was able to use it as it’s considered ‘Fair Use’ so we’re back!
i know its basically a piece of motor racing history, but it would be a waste not to use it. Don't keep it good for the sake of it, build an engine for the turbo and enjoy it! really cool video!
Yeah and Idk too much about turbos but I feel like a turbo of that caliber is rebuildable. I know my dad took a couple messed up centrifugal blowers and re machines them and bad them work again. So as long as a turbine doesn’t grenade and toast the housing I’m sure it could be kept in working order for a long time
Ahead of their time. Turbos/superchargers already had this profile in ww2. Centrifugal turbine engines have had it well before the 80's. What is mass produced is just the cheapest to produce, not what is available.
What could be better than owning this turbo? Listening to it doing work strapped to that 20vt. Like those TAG F1 powered porsche 930's but on a regular person budget.
@@andybrooks7908 Worse, drivers of that time had to endure up to 2 seconds of turbo lag. They had to anticipate the corner exit and go full throttle well _before_ the apex, so they had full boost by the time they exited the corner. Also: an engine in qualifying trim would only last a few laps. The radiators were simply not able to dissipate the heat output of 1400-1500 hp. They didn't do budget caps back then.
in an article in I think CCC magazine in the renault museum they had a F1 turbo engine that maxed out a 1400 bhp dyno and it still had 2k revs to go ,at the time reading that blew my young mind totally as my mums new 1.6 pinto mk4 cortina made 75
That could bea RUclips thumbnail of me spending my last two cents on a very expensive mod for my shitbox when i should have bought a present for my gf's birthday.
Your knowlege on this subject is incredible, mad respect mate. Sure does look like you've snagged yourself a piece of history. Be a shame not to use it though
Thanks! Seems like it to me too. Would be an incredible coincidence to be anything else as it’s such an odd spec and would be little/no point for anyone else to build one like this.
hey definitely an unusual turbo! have seen a few unusual turbos tested in truck engines as well. However, I have never seen that compressor. as you say quite unusual design for the Holset until modern times anyway. mvh jens gustavsson
There is a company in germany that make custom turbos worth about 20k a pop. Billet compressor wheels, carbon fibre compressor housing and titanium turbine housing. They are incredibly light.
@@StavTech who knows. Plenty of projects in the world, not everyone wants to take photos and share. A lot of stupid people and negativity on the net, especially youtube. That is why I don't share my helicopter build.
@@StavTech I'm sure I read in CCC back in the day when they started talking above turbo vs na that the focus for making power shifted from the induction side of the engine to the exhaust side. As soon as you started talking about how smooth castings were internally, a little alarm bell started ringing in my head, because it can't have been a simple process to get that level of surface finish. Complicated processes suggest big money, and you don't pay big money if you're not getting results. As for the internal surface finish on the compressor side, as I said, the compressor side is less critical, as the volume of gas you are shifting is less. Dunno, just some ramblings from a grumpy old bugger to confirm that what you've got is more than a bit special ... thanks for the show and tell
Very interesting video mate new to your channel🙂🖐 I like my car stuff I know you can pick up Turbos for a couple of £100 just curious how much you paid for an F1 turbo I do understand if you don't want to say I'm just curious🤔❓️💯👍
all these boost lag comments, they had pre turbo throttle bodies, rocket anti-lag, and tons of other ways to manipulate boost. Over boost, the list goes on and on... check out 24:54. You can see the rocket anti lag system in plain view..
Twin scroll turbo's from that long ago would surely be from motorsports, the tech they develop then trickled down into road cars a few years later in the late 80's early 90's.
@@StavTech They were at the early 2000 copying old f1 tech into turbos as sweden dragracers wanted 'cheap' and reliable turbos. Holsets were very popular. as they can take a lot of abuse.
@@StavTech that is pretty much the story with these 😂, I’ve had to install forged pistons and steel con rods to give it a chance at a measly 300 odd hp
From the pictures you showed the housings look the same but the center cartridge is different. not sure if they used longer wheel shafts back in the 80s but i heard somewhere that f1 turbo cars used a longer shaft to keep the heat away from the comp side.
It showed HX50s which is same core but smaller compressor housing, and some bigger ones which was different core but same compressor housing. This is some mix of both
it does look to me like its a raceing turbo but i think they used a cummins turbo it looks a lot like them but with the air inlet shaved down and the cummins turbo has far more casting marks. HX35 Turbo For Cummins 6BT 5.9L Replaces Holset 3539654H. but i do think it came off of what u said i just think that they posibly need to figure out what to use thease for cause f1 isnt using them no more so i think they desided to start useing them for cummins engines. they have the same oil spots the casting on them is the same sized but not as polished the cold side air inlitet and hot side air inlet just a lot longer. but undunder the serface all the same the blades the same. now i dont know when cummins started with the engines but i do know they look a lot similar.
Holset turbos have been on tens of thousands of engines since the 1950s, including all Cummins since the late 70s. This isn’t a production one, before or after.
Every part on every F1 car needs to be traceable and individually identifiable. They are ALL identified by being hand engraved with a unique number. IF it is an F1 turbo it would have this. The 'SK' engraving would seem to be this number and WOULD be traceable to when it was used and by what driver. Not sure who would have the records for it now. Most if not all race teams use this system.
A turbo from 40 years ago, from a engine supplier that no longer exists, for a team that no longer exists. Considering the how unoriginal most historic race cars from that era currently are, I’d be amazed if anyone has them records
Can you measure inducer and exducer for the turbine and compressor for us? I wouldnt use it on a car. You dont know how well it was rebuilt internally, if it was balanced correctly or not, etc and a huge risk of ruining it. Very tempting but not worth it. Would love to know the dimensions of the wheels, though... Thanks for the video!
@@nesmio7378 well as you say, eBay, Facebook marketplace, anywhere where things are for sale, stuff randomly appears sometimes. There’s nowhere special. I mean there’s places like Racecarsdirect but then the people usually know the value so they are not cheap
At a guess its all port matched and polished throughout? I mean i wrap cars... not build race engines... but when comes to f1 they would go to extremes, were there any grp b rally cars running these turbos as would be a simmilar time too?

Yeah exactly. Seen hundreds of Holsets from that era and beyond and that’s. It normal wheels.

@@StavTech do it
I so very much agree with the statement above
Pretty sure it's time for some forged pistons, and 3.5bar of boost in the MR2
this
Congrats. You were the perfect person for this to end up with. Thanks for sharing.
Amazing the horsepower these things pushed back in the '80's.
Yea i think they was pushing close to 1500bhp and I'm sure they was only 1.5litres
Right. And then think of the utterly _MASSIVE_ turbo lag that these weapons had!
@@Hydrazine1000 bet they was a right handful when they come on boost mid corner
@@andybrooks7908 Worse, drivers of that time had to endure up to 2 seconds of turbo lag. They had to anticipate the corner exit and go full throttle well _before_ the apex, so they had full boost by the time they exited the corner.

@@Hydrazine1000 it must of cost them a fortune in rebuilds back then
Fascinating stuff. Also funny that for a while now, just about any Holset internet search links back to one of your pages or videos.... 😅
Yes Stav time is o stick it on the mr2
You really have a Turbo hording problem... and i love it
Great find, great knowledge and great explanation
in an article in I think CCC magazine in the renault museum they had a F1 turbo engine that maxed out a 1400 bhp dyno and it still had 2k revs to go ,at the time reading that blew my young mind totally as my mums new 1.6 pinto mk4 cortina made 75
Looks like it had very light use, then was rebuilt probably as a spare, with resurfacing etc? So maybe used on a qualifying or similar run.
That could bea RUclips thumbnail of me spending my last two cents on a very expensive mod for my shitbox when i should have bought a present for my gf's birthday.
Now this one, i've got to watch multiple times.. Thanks again for providing stuff interesting as
This would be rad to see putting in work ... radical find my brotha ... peace and love bro keep it rad stay safe and build on.. l8z famz

That`s fecking awsome Stav mate what a find you lucky sod get it bolted on ASAP would make a fantastic video
hey definitely an unusual turbo! have seen a few unusual turbos tested in truck engines as well. However, I have never seen that compressor. as you say quite unusual design for the Holset until modern times anyway. mvh jens gustavsson
Glad you agree too, was very surprised!
First thing i thiught when seing that turbo was senna mashung the pedal like crazy to spool it up and twist the car mid corner....
It's race car stuff, so use it for race car stuff because race car!
Please accidentally install this on something in the future!
would be cool on some period correct 80s car :D
Wow you’re a lucky man 😮 please please bring this back to life
The second to last image in this video is amazing. Would love a hi-res version.
That is a sweet turbo 😮
There is a company in germany that make custom turbos worth about 20k a pop. Billet compressor wheels, carbon fibre compressor housing and titanium turbine housing. They are incredibly light.
If it’s the one I’m thinking of, you ever seen one actually used on a vehicle? As I haven’t
@@StavTech not seen personally. They are intended for race applications. Not sure about titanium turbine housing durability long term.
@@StavTech turbozentrum
@@chippyjohn1 yeah, nobody actually uses them. If they were any good people would
@@StavTech who knows. Plenty of projects in the world, not everyone wants to take photos and share. A lot of stupid people and negativity on the net, especially youtube. That is why I don't share my helicopter build.
The exhaust housing could be extrude honed. Wonder if it had more to do with avoiding cracking than flow, hence the compressor isn't as smooth.
Yeah, good shout, didn’t think of that, and makes a lot of sense. Good thinking! 👏

No, twin scroll has been around for ever.
@StavTech pretty sure the bmw turbo used a twin scroll housing from a truck.
So cool.
Most people wouldn’t get it, but for car/turbo geeks like me, it’s like Christmas when I realised what I got 😂
To me it looks like something 'svensk turbo service' could be responsible of.
And that makes it just ~20 years old.
What makes you think it’s anything to do with them?
@@StavTech They were at the early 2000 copying old f1 tech into turbos as sweden dragracers wanted 'cheap' and reliable turbos.
Holsets were very popular. as they can take a lot of abuse.
I have one of them in my shed
I believe you
They sandblasted the interior, and the wheel is forged metal. Blades are curved to increase velocity.
Reminds me of the guy who found a McLaren F1 V6 in his backyard on Reddit
I own a efr 7163 from an Indy car. Sadly it is too small for any of my projects.
With the Indy housings? I might be interested, the housings are a different spec than retail 7163's besides that they are the same as available 7163's
Only thing cooler than owning an F1 turbo is running it.
i hope to see this relic screaming on the 1.8t
Wow what an amazing find bud , if you have any advice/good bits for my corsa c Z20 setup I’m all ears ;)
My only Z20 experience was my Astra blowing up in no time with almost no mods, unfortunately 😂
@@StavTech that is pretty much the story with these 😂, I’ve had to install forged pistons and steel con rods to give it a chance at a measly 300 odd hp
Stick it in the MR2 and then link up with Overdrive to test it with F1 Wheels
I want it for my EK Civic build. Lol

Now just slip, fall, and accidentally install it on something light and high revving!
Already have one of them
Its time for internals
Looks like there's a couple chunks missing off of that compressor wheel
Welcome to the world of “that’s how compressor wheels are balanced”
It's off a 12valve Cummins
Not even slightly close in any way
@CaseyPutsch might be able to tell you more about it.
Really cool but of kit mate.
it does look to me like its a raceing turbo but i think they used a cummins turbo it looks a lot like them but with the air inlet shaved down and the cummins turbo has far more casting marks.

@@StavTechyeah so much secret R&D going on back then i doubt it too 😅
3d scan it and reproduce it. Use the fluck out of it.
Is that a decent size chip missing out of pump wheel or was it designed/balanced like that?
That’s how most compressor wheels are balanced
@@StavTech Good to know that was a safe assumption, cheers.
Could "PC" stand for "Prototype Casting"??
Possible, but honestly I think the comp housing is a production casting, not sure 🤔
Old school balanced did you knotice the chip/cut in the wheel exducer for balancing
That’s how most turbos are balanced to this day
Can you measure inducer and exducer for the turbine and compressor for us? I wouldnt use it on a car. You dont know how well it was rebuilt internally, if it was balanced correctly or not, etc and a huge risk of ruining it. Very tempting but not worth it.
Would love to know the dimensions of the wheels, though...
Thanks for the video!
70/102 comp, 76/84 turbine
@@StavTech thanks!
So are you gonna collect it or throw it on a Project is the Big ????
Won’t be straight away if I use it as I wanna use the car not just keep building it. But when the current engine blows up? Maybe…
Bullshit,it's a holset off an L10 cummins
Madness how people can be so wildly wrong but say things so confidently
Did they have twin scroll turbis in the 89s f1 cars??
Twin scroll has been around for ever. All the 4cyl F1 turbos engines of that era, Hart, BMW, and Zakspeed, were twin scroll
Cool score and find! Gratz.
Where do you find motorsport turbos like this one for sale? Ebay?
All over the place, just need to keep an eye out

put it on a formula ford or something like that
❤
Put it on an old 1l Micra 🤣
Sure it's not off a Cummins.....😉
Yes
Or maybe a Volvo D13... Actually they have the HX55
There's a chunk out if that comp wheel
Two very precise machined chunks, to balance it
Balancing marks. Like on every turbo ever made.
for balance properly
Ah ok, didn't realise they ground the weight out like that. Fair enough.
Thats not a f1 turbo 😅
Right. What makes you say that then…
Because it's a stock standard commercially available holeset
Points to exhaust wheel and calls it 'super shiny'... Willy nilly introducing meaningless words in sentences is normal for stav.
And is picking at things like that for no reason normal for you?
It is super shiny!
And I was talking about the turbine housing outlet, not the wheel. As it is unusually shiny… 😂
