Tuatara competition

0-460km/h and DEMOLISHED the previous record particularly in distanced needed. I'm busy on an Italian project so this is just a bookmark!
But it's quite easy to see the start was neither quick nor launched controlled. They'll take seconds off it! Already did 300-400km/h in 10 seconds or under!
Oh she's got a hell of alot more left in the tank! ;)
lafars 1d ago
300-400 wasn't far off the 10 second mark
i do have theory about the 1st run regarding the numbers:
the numbers that were seen were based on a formula for top speed based on Power, Drag and Gearing, however since the formula had not taken everything into account it ended up with deficit (4% was stated), this can be seen in his response on TG where he states 350mph/7th gear, that's why the numbers were off
this seems like a high estimate at first until you realize that Engineering Explained reached 345mph theoretical top speed with his calculations (same calculations as he did with Jesko/331mph)
later they've released an instagram story where they said the current calculated top speed is 339mph (probably taking everything into account as this is the most conservative)
i just hope we can get a run soon
ChironSS 1d ago @lafars
Well you know I Love the car man. Alot. But the first run was a complete mess. I can't go into too much detail, but I LOVE really going into detail. I saw some research put the run at around 290MPH just under, using acoustics etc. It was still probably just enough to get the record, but they couldn't prove it and more to the point had no data. At all.
I actually for a brief period interacted with them on something seperate and I really really rate Castriota and Caplin, it's really more because of them I'm onboard still. But whatever it doesn't matter.
They've got current productions record period. The last one wasn't official and they had engine problems too! One of the four fuel pumps was ****ed accordingly to the driver.
So the next run accordingly to those I exchange information with will or should exceed 300MPH two way average. The Grail is 500km/h two way average but that's going to be incredibly difficult at NASA. But we'll see.
I know it'll succeed based on a number of seperate factors.
The designer is ex Pininfarina? Compare the Tuatara to the others including even Bugatti? There is no comparison whatsoever, it's like a childs painting versus a masters. It's an incredibly delicate masterclass and masterpiece is sculpting. Look at his previous portfolio. For some that will be enough. That includes me, even it is subjective,
because objectively they've done masses already and I'm looking forwards to the adventures with them plus their competitors.
As Jerod Shelby stated once the dust settles they'll be the fastest. Difference is he wants it even more now!

Quote>"The engine was first revealed this past August and will displace 5.9 liters, down from a quoted 7.0 liters when the original Tuatara concept bowed in 2011."
Are you purposefully so docile and dense you can't tell the difference between SEVEN litres and 5.9 litres in terms of cubic capacity? They are COMPLETELY different engines in every possible way you from the original 2011 engine you ****ing moron?

So they failed to make an emission complaint engine and 5 years later they suddenly have a smaller engine that makes even more power, revs higher and meets much much stricter emission standards? Sure.

And finally SSC North America claims the dry weight of the Tuatara is 1247KG. Source Wikipedia.

I believe the SSC Tuatara is atleast capable of matching the Koenigsegg One:1 to 300km/h that's under 12 seconds. 300-400km/h with boost coming on much further down in the gear range it will totally destroy it as on reduced boost levels it did the metric in 10 seconds or under.
So the 0-400km/h might go 21-23 seconds. It might go under it might go over. But when the Nelson's Racing Engines V8 gets pumping at those higher ranges, until proven otherwise, I don't think there's much on the planet that will keep up.
Maybe John's car. I'm actually more interested in instrumented testing for the car vs top speeds really. And I'm sure she's a sweet steer too dynamically and they should go to Laguna Seca and COTA etc.
There would be no shame in coming behind the Czinger 21C. That cars a monster too!

lafars 4d ago @ChironSS
i was thinking of theoretical top speed and acceleration plotted on a graph
anyway, i experimented with the friction coefficient and at 1.3 the 0-200kph graph matches the holy trinity/chiron and reaches 300kph at 10,5s matching the One:1 and 400kph at 18,5 seconds (at 1.1 it reached it at 21 seconds and at 1.2 it was 20 seconds), i don't know the frictional coefficient of the Michelin Pilot Sport Cup tyres however, so it's all guesswork trying to align it with reality
last edit: i noticed on the standard 1.1 friction that it does 200kph in 7.9 seconds and 300kph in 12.5 seconds, so roughly 3.5 seconds from 200 to 300

So, I estimated the first curb weight figure using the initial corrected (or atmospheric equivalent) displacement figure of 1096.5 cubic inches, and it turned out to be 4,086 pounds or 1,853 kilograms using the "race car (prod. model)" setting.
Converting to just 91-octane fuel, the SSC Tuatara makes 1350 hp. The E85 option will allow it to make 1750 hp. E85 is 105 octane fuel, but it ONLY increases power if your car is supercharged or turbocharged. In other words, E85 sees identical or worse power outputs in atmospheric cars than regular or premium gas.
Maintaining that same VE boost rating of 84.99%, the car delivers 19.78 psi of boost, which is accurate considering the whole car was limited to just 19 psi during the alleged "300-mph" top speed run. Now the corrected displacement is 846 ci (13.863 L).
New curb weight estimate is 3595lbm/1631kg.

Homologation.
Funny how Robert Mitchell's name is used in one specific and individual area and not others? Hypocrisy is rife! Not surprising really there's alot of jealous triggered haters.
Anyway he goes into to depth about what constitutes a production car and SSC's reply regarding OBD compliancy and 50 state legality etc.
Also the previous generation car had full EPA/DOT clearances otherwise it wouldn't have received official Guiness World Records recognition or certification for the Ultimate Aero production top speed record.
So the SSC North America Tuatara is the World's fastest AND quickest top speeds production hypercar.
I checked actually the percentage differences between the current record holders and the previous records, at 300-400km/= it was 19.17% and 400-450km/h= it was 38.09%.
There's nothing else to say. Even I've not seen that level of destruction. Bugatti doesn't count because it was a one way run in a pre production prototype, but I absolutely know what the 300-400km/h time was vis a vis SSC. The same.
Atleast SSC ran a production car with the owner driving. Class act.

https://www.musclecarsandtrucks.com/ssc-tuatara-gets-methanol-fuel-capability/
Quote>"As the world continues to search for new, clean and renewable energy sources for combustion engines, methanol has raced back onto the scene. The opportunity to integrate expanded capabilities into our existing platform became obvious when we also realized the sweeping benefits of using a synthesized methanol-based fuel in our Tuatara, Striker and Aggressor powerplants”, said CEO Jerod Shelby. “As methanol is among the most promising alternatives for significantly shrinking our cars’ carbon footprint, we decided to offer it to our customers and incorporate it into our flex-fuel arsenal.”
Expanding alternative fuels? Very impressive. I wish Bugatti would do something like this. But they've got a, well according to rumour a NATURALLY aspirated engine with hybridity coming and I'm sure Mate Rimac understands this.
As for SSC North America still the top speed production record holders PLUS acceleration too above 300km/h. 300-400km/h in 10 seconds or under destroying the previous record and above 400km/h without full boost completely decimating every production car from the factory delivered to a customer no questions asked or needed.
And Bugatti will need to run the production specifications Chiron Supersport in an acceleration test to prove it's quicker. Unlike some "fans" I'm not a hypocrite.
Looking forwards to the track variants too. Both of them. As it stands unless John Hennessey does a run it's production hypercar of the year in terms of ultra high end speeds and acceleration and undoubtedly one of most beautiful. That's NEVER going to change.

Look what I found :D
So, apparently, during the 286mph run, the car lost power and THAT was the reason why it started decelerating at the end, not because driver lifted early as some might claim.
10 years of development and the final product can run on full power just for a few secconds. This thing is a joke.

Here's my own calculation using my own formulas or equations. The weather condition that I used was that of Titusville, Florida, just a few miles to the west of the runway, near sea level likewise. The date and time was when the run was done, according to them. All the relevant information are credited to these sites that I use in my calculation. The powertrain factor is of my own making which I will not divulge here. The top speed of both 312.4 and 305.4 are what I got solving my equations. As what happened, the speed only got to a maximum of about 286 mph because the car needed a longer road. Had it used up the whole length of the runway, it could have gone faster, but the car had to brake and stop eventually which it didn't have the luxury. Finally, one would notice that using different tire pressures amount to different speed. Well, the higher tire pressure results in less rolling resistance, and vice versa, if you follow the equation given by the engineering toolbox. Both tire pressure and speed of the vehicle affect the rolling resistance or coefficient of rolling resistance and eventually affect the speed or top speed of the vehicle. Using coefficient of like 0.015 is only valid at ordinary highway speeds like 50-70 mph. Going at high speed like 200-300 mph, the coefficient increases dramatically and slows the car down dramatically likewise. Had you use a much lower number like 0.015 or so, the top speed would reach 330-350 which is ridiculous!

So and I've been digging, the number that kept coming up over and over as a "semi" official 0-100km/h time. And that number is 2.7 seconds which I feel is a fair number. It'll be interesting to see it run a 0-400-0km/h attempt. In my estimates it's going to go under 30 seconds.
