Driving a 750hp Twin Turbo Diablo... FAIL!

[@darnell1320]

Sounds like it has a manifold leak. With some updated turbo technology and engine management system. Car would probably be a beast.

[@ammarkhan3160]

Exactly my thought. Sounds like a blown manifold gasket or potentially a leak. Would start with that, and actively search for boost leaks. With modern turbo tech this thing would be a monster

[@HashMaster1776]

Can hear the boost actively leak as he’s on the throttle haha wouldn’t be a bad idea to tear the motor down anyways, maybe change the rings and touch up those cylinder walls. Just to make the block somewhat “fresh”. Small and cheap

[@TheS1PikesPeak]

Jep, also my thought. Gasket blown or manifold is broken

[@maraudingmerc9381]

One of the most amazing parts of the adventure with these cars is getting to understand what actually went into them and getting to fully document what's going into them now. I can't wait to see more on this VTTT.

[@breakupgoogle]

Freaking LOVE it! I didn't think these were even real. just something from a videogame. Props to the owner for building it up right. it deserves to be a killer.

[@rjnation5042]

Curated has become one of my favourite channels on U tube, just a stunning collection of amazing cars, every week, looking forward to seeing what you take to Monterey, Rj in Oz

For sure....never miss an episode every week!

John - As always, thank you for showing us the best of the best. I enjoy your content so much. These examples you show us are just incredible and we’re quite privileged to be shown it.

[@chrissmith4713]

The 90's supercars are the best....and in Miami?!... killing it John! great content and stories

[@ericswires8534]

No kidding. Talk about living every guys dream.

[@Sir.VicsMasher]

Stoked on the VTTT content. I'd love to spec a build like this.

[@CoastalAutoReactionCAR]

Eleventy Million Horse Power! Great drive guys! Take that Jetta to school! 🤣🤣

[@bmarsack23]

I was able to stop by Curated yesterday and it was a pleasure to be able to walk around and see so many incredible cars!

[@hennricc-5238]

Thanks for the flashback. From the title I thought it was the Nelson Racing 1000hp TT VT. Just looked up that video, 9 years since they dropped that!

[@jasdhillon9299]

There were only FIVE VTTTs commissioned through Vik K. and his Lamborghini dealerships. This car is not an official/original VTTT; it was commissioned separately through the owner and Greg Armstrong.

[@WeAreCurated]

Wow! So interesting to learn. Thank you. Greg produced all of the VTTT for Vik K from our research. Will continue to dig!!

[@jasdhillon9299]

Greg Armstrong is very hard to reach these days. He can confirm. I have No. 4 and have a tethered history on them. Mark C. owned it for a decade, and he was able to learn a lot more from Greg. No. 1 was red and belonged to Mike Tyson. The SVTT was NOT one of the original FIVE. No. 5 was a red, fair-weather car originally sold to the SA Foreign Minister of Finance.

[@DB-fn3fz]

@@jasdhillon9299 Jas, you've got excellent taste in cars from what I saw on your ig. I had no idea you had a VTTT. How does it compare to the F40? Formally requesting that you upload a video and share some of your knowledge about it with us. -Dave B

[@Thatguy55595]

@@jasdhillon9299 Can you confirm that your original VTTT makes 750hp?

[@GaIvatr0n]

@@jasdhillon9299 Great insight. I'm a big Tyson fan. I wonder if this was prior to his yellow Diablo. * Edit saw your comment below Jas denomonating which No's were which colours.

[@juniormeghji2551]

You can hear the ignition break up. The plugs and wires have to be shot. Plus back in the day turbo lag was accepted so I'm sure the hot side was paired correctly with the motor. I would rebuild the turbos with the original housings but change the internals. Possibly contact Borg Warner and see what they have. Their internally gated turbos are fantastic now. Internally gated turbos have come a long way now. 5 years ago I wouldn't even consider one. But that's an art piece. Congrats on the new Diablo. I used to have the red VT TT as a poster.

[@Lext87]

Yes thought I could hear it misfire too especially later on in the video. Came to the comments to see if I was the only one.

[@catsaretasty]

Looks like a nissan 300zx twin turbo sticker on the back

[@fixyourautomobile]

Looking forward to the build. Spent two years in Miami. Had a good time while I was there!

[@pedrorocha1425]

Such a dope piece of history. It deserves a propper fast 750hp setup

[@skydance2012]

Lots of big smiles on you guys! Nice to see you guys relaxing and real as always!

[@matthewelliott2213]

I still have the DuPont Registry with one of these beauties!

[@donjuan150]

That magazine was my bible!

[@mouse5178]

Yes, I’m from Scotland and when visiting the states in 93 for a two week holiday at 14 years old or so, I bought my first Du Pont Registry. I couldn’t believe the cars I was seeing, so amazing

[@godchi1dvonsteuben770]

Pretty sure the TT boost control is the fan speed control knob, in the upper left of the center stack. During the conversion they bypassed the fan speed switch, so it's always running at the same speed, when climate control is on. This leaves the fan speed control unused, then repurposed for boost control.... One more thing, DeMuro's review...

[@GaIvatr0n]

KEY info! Very Doug of you.

[@travertinepico751]

I remember seeing I believe the blue one for sale in a DuPont mag in the 90s - 455,000 is what I recall.

[@oviedosantiago]

You have the best takes with the perfect music in the perfect place.

[@Alps6408]

One of the best-looking cars of all time.

[@mouse5178]

I feel the same. I use to own a blue 96 VT and they are just incredible cars and very easy to drive too. Always ultimately wanted a 6.0 version though

[@investfourmore]

I remember a guy tried to twin supercharge a diablo. He was documenting it for a while and then nothing.

[@Thatguy55595]

Probably because it didn’t work right

[@techniqueswithtodd]

7 of these in the entire world. VTTT (Viscous traction twin turbo) A LEGEND. Hopefully you guys can make it live up to it's badge. It's a VTTT which is special and important. Especially these days.

[@scottwilson1251]

There are actually 10 total according to a few websites. A couple were called VTTT's but actually had twin superchargers instead of Turbos. I would think it would be easier to make a SV into one of these, that way you don't have to worry about breaking the 4 wheel drive Viscious traction system.

[@ricardolugo9102]

LOVE this channel. I would quit my job in sales to work for him and If I had the opportunity to speak with the Diablo client I guarantee I would be able to talk him into a fitting a sequential transmission and a underground racing Diablo twin turbo stage 2 (car# 01 Diablo tt package) and suspension over the phone I miss working in the automotive industry 😌

[@pkop2jz]

I love it even in its current health condition, thanks for sharing it with us! On a side note, did the Diablo steal the "Twin Turbo" badge from a Nissan 300zx TT too!?

[@davesalichuk5961]

Heffner Performance was the first shop to twin turbo a Gallardo and his kit whether it be Underground Racing, Dallas Performance or Sheepy Racing that is the kit they all copy. Heffner is the man, he is in Florida just south of Tampa amd that’s who you should get in touch with.

[@grad0n]

I hung out at Heffner’s house in New Carrollton, MD back in our skating days.

[@dougshaw2944]

I'm super excited for this VTTT Dude was spot on, I had the yellow one as a screen saver back in the day.

[@Thatguy55595]

Waited my whole life for you to make this video.. thank you. And btw was the boost not fully turned up? Maybe that’s why it felt slow

[@drewmurray2583]

Sounds like it's running on all 11 cylinders!

[@MichaelBlueMusic]

I’m with John on this, leave it how it is. Everyone knows about them and only 7 were made. But, now this one will be the famous “Curated/Underground VTTT” so that’s something too. Again, loving the candid footage, and you couldn’t have picked a better song for the end. On another note…Sometime you should do a long (30+ minute) “midnight drive” in a white Countach and put some synthwave to that. Instant viral. Heck, make them a series and do a bunch of your inventory that way. 👍

[@Rick-N-Something]

Speaking of subscribers.... this channel needs more.. great car and content as always JT •TT

[@finaltouchautodetailingllc]

What happened to the Diablo SV that was white and used for a Victoria's Secret ad that had the SV reversed and was VS?

[@slaytalera]

I’m sure Underground would be great but Nelson Racing Engines did a few built block TT engines, I’ve not seen one in car but I’ve seen them post pics of their long blocks on social media, maybe worth checking out given their reputation in racing

[@Wopadas]

Big no on Nelson. They've literally had that Diablo for 10+ years now and it still doesn't run.

[@gregfair1749]

I remember these VTTT Diablos from when I was a teenager in High School!!!

[@mateuszjanus9773]

The shoots at the end with Miami Vice vibe 👌🏻

[@cencio_1976]

Where's the video of Hoovie's Diablo you bought?

[@captaincoffeecake3595]

honestly with how old those turbos are that car would benefit greatly by just replacing them with new counterparts , no way those havent lost some chooch over the years, plus turbo tech has come a incredibly long way since those were designed.

[@aarongarner8452]

I love when people rev cars up when they're cold

[@christopherpereira8580]

I feel like it wouldn’t be right to be in Miami without a Lamborghini or Ferrari. The Miami vice shows and movie and movies that make u want to be in Miami is what also made it. Miami also wouldn’t be right without John and Curated! Keep up the great work

[@MrDubbindan]

I may be old school but I hear valve train noise when he’s on throttle . It’s like it’s in severe need of a valve adjustment .

[@kentbeitel9966]

That sounds so good! 🔥👌 never even knew these existed. I wouldn’t care if it didn’t make 750hp, just the looks and sound alone I think makes up for being “underpowered”

[@VF1Skullangel]

Id love to see you guys get a hold of some of the Albertoni cars and bring those back to their glory

[@exoticcarfactsofficialchan7050]

For what it is and the era that this car is from, it sounds magnificent 😎👏

[@giorgiodelpalatinato6718]

The necessary turbo technology is now available, make that car what it should have been from the beginning! Just give it to a turbo-refit expert and let it sort out. In this case it is better to have a not- original but working car, doing what it should do, since it's not original anyway, ie modifications wouldn't spoil it.

[@chadfent3987]

Knock @ 6:44, thought it was over-turning of the wheel but then you went further. Then it kept making that light knock no matter what the steering was doing. What is happening there? Does the rack need rebuilt?

[@rickhayes8009]

Nice to see this car is licensed in Canada. Even if the car is... complicated! 😎

[@GreekPower]

Judging by the video, it sounds and looks like the car is on 6psi and not 9psi of boost. hence the 600hp (probably around 520whp). I'd love to see it dynoed before removing the engine. Can't wait to see the content with the rebuild and engine building and hopefully modern tech on the turbos and tuning etc. I'd bet this diablo would hit 1000whp EASILY with a modern build

[@amacca2085]

A civic can hit 1000hp easy so I’d imagine it would and in you can hear 3psi on a KZbin video then you should be doing something else with your time

[@scottwilson1251]

​@amacca2085 Any car can hit any number if you throw enough money at it. A Civic can hit 1000hp easy? Lol right cuz they start with so much to begin with. A turbo Civic making 1000hp is probably running some ridiculous boost like 30lbs if not more.

[@tommyhughes6576]

That turbo sound though, amazing but wrong, yet so right!😍

[@harrybass617]

Thanks for the amazing content boys much love from a huge Armenian brother from Boston

[@srreventon]

What ever work you do to the engine... you MUST ceramic coat the exhaust manifolds to reduce the radiant heat in the engine compartment and i would also use redlines water wetter with the coolant.

[@briankearn6991]

Those engines were built with thicker head gaskets to lower the compression ratio so they will be less powerful than stock at low rpm until the turbos spool up. They’d be set at 6psi to be reliable and would make less than 550 crank horsepower at that setting. 8psi would make about 650. Add a hundred for marketing purposes and you have 750. 10 psi would make 750 and blow up quickly. Stock compression ratio with low boost, 8psi, modern turbo and engine management systems and E85 would get over 700hp (about 50% more than stock) reliability with extra torque everywhere. The cylinder heads will flow just fine too, no need for extra injectors just higher flow and modern engine management and experienced tuning.

[@raphschd]

That car is probably the last project Ferrucio Lamborghini saw before dying.

Was the A/C just not working or did they remove it to fit the turbos or something like race car builders like to do ?

[@johnm1008]

Adjusted for inflation these were just over $1,000,000. That's a lot for an unreliable Diablo that doesn't make the advertised horsepower. It sounds good though.

[@theneck5157]

Back in the late 70’s through the 80’s snd 90’s I was a Porsche fan boy the day I drove the turbo I was hooked plus Porsche as a manufacturer was always known for being reliable something Ferrari and Lamborghini never were !! The Italians made weapons of beauty but always and I mean always had problems and Porsche especially when the Turbo hit the market was just perfect in my eyes especially after the movie no man’s land with sheen hit the big screen ..
