2023 Aston Martin Vantage V12 776HP after dyno run
Discussion
2023 Aston Martin Vantage V12 Dyno Run
(PM me for the results)
Base Information:
All-Alloy Quad Overhead Cam, 48 valve, 5.2 litre twin-turbo V12 Water-to-Air charge cooling
Compression ratio 10.5:1 Final drive ratio 2.93:1
Dual Variable Camshaft Timing, Fully CNC machined combustion chambers
Maximum Power: 700PS at 6500rpm
Maximum torque: 753Nm at 1,800 – 6,000rpm
Redline: 7000rpm
Top Speed: 322 km/h
Lightweight package: Carbon Fibre brakes, racing seats, and lightweight wheels shaving 36kg off the overall weight.
Summary of Dyno Run:
Whilst the redline is 7000rpm I decided to use 6800 (which lowered the results a little bit).
Using Dynapack 5000 Hub Dyno by HiTech Motosport (45 years in business and a trusted and experienced tuner).
Wheel Torque: 734Nm at 3191rpm (using 10% loss equates to 816Nm at the Crank) – 5th gear
Wheel Horsepower: 642HP at 6,800 rpm (say 660HP at 7000 rpm using 10% loss equates to 733HP at the Crank) 5th gear
Quarter mile: 10.45 seconds at 212 km/h at 5884rpm
HiTech said Aston produced a racing engine in this car and the linear speeds are like that of an EV. The Aston Martin dealership was blown away by the results.
The CEO of Aston Tobias Moers (ex CEO of Mercedes-AMG) took the Vantage under his wing to create the fiercest, fasted Aston and judging by the results nailed it!

The V12V was pegged back by using the same ZF from the V8 rather than the higher rated version from the DBSS.
Whilst I don’t doubt the engine can produce these numbers with the right ECU, I doubt AM would let them roll out the factory gates with 80lbft more than the gearbox was rated to.
The dyno either sounds very generous, or the example in question has possibly had a remap.
I’ve not driven a 2C V12V but most reviews commented on a surprising lack of grunt given the engine and a notable shortfall of mid range torque vs the DBSS.

DMS do a stage 1 for my DBS rated at 800hp but i want to address rear traction first..
Edited by Lifesbloodygood on Tuesday 18th February 06:25
This is a theoretical speed and is based on the gearing from Aston Martin. I don't think it could do it, but the car definately has long legs!
The 1.6g is per the dyno graphs. I think the point here is the car is still pulling right through to 6800rpm and if the limiter was taken off would keep pulling.
The dyno used is one used by professional race drivers all over the world and has an excellent reputation.

My car is still breaking in, with not many Kms on it. All the reviews I have read on my car talk about its monstrous speed.
Check out this video on the Belgian F1 cleaning up a GT3RS.
Yes it did have an underrated transmission but appareanlty still within the safety limits as I checked wih ZF.
It is totally stock, thought about a tune but have been advised not to do it with the results it is producing.
Most manufacturers understate their performance figures for emission reasons.

AM Ricardo please send me those reviews as I thought I had read most of them and no one has ever accused the car of having a lack of speed.
I should know - my last two cars were a Ferrari F12 (740PS but lower torque) and a 2018 Bentley Supersports 710ps 1000Nm, both very quick cars but the Ason would beat them both especially on the track. I have had Porsches and Mercs too, but nothing as quick as the Aston even with 630HP.
Check out Youtube Getting Coffee in the NEW Aston Martin Vantage on the Belgian F1 track to know how seriously quick it is!!
Thanks.

A dyno run cannot measure (or even estimate) acceleration g-forces. It measures torque and extrapolates a power measurement. According to Google, an F1 car gets up to 2g on acceleration. There is no way that a road car, on road tyres, weighing double an F1 car and with about 100bhp less than an F1 car is going to pull anywhere near 1.6g at any point, other than perhaps for a brief moment at the initial launch.
The claim that’s it’s still pulling 1.6g at 350kmh is pure fantasy and if the dyno company told you this, then they are also delusional. In fact, I’ll wager that the g-force at 350km/h is zero, because I doubt the car will even reach that speed, let alone the theoretical 472km/h. Remember, a Bugatti Chiron needs 1,479bhp to go 11mph faster than your theoretical top speed.
I have no doubt that the car is epic and is very, very fast indeed. I’m very jealous and would love to know what it’s like to drive a Vantage with around double the power of my lowly 4.3 VH2 Vantage. However, ridiculous claims just make you look a bit silly, especially amongst people that can see through your ‘stats’

It can't have been pulling any g as it wasn't going anywhere.....
That is an extremely salient point - well I suspect for this universe at least :-)The g forces mentioned strongly appear to be theoretical calculations / extrapolations / exaggerations from the dyno data !
Unless of course the whole exercise was conducted near to a BH event horizon !
Sorry to add some more negative comments, but you cannot assume it makes more power at 7000 rpm than 6800rpm, most cars tail off at this point and few cars make peak power at the redline.
Also a 15% loss is too high for a hub dyno. Hub dynos are generally considered to lose about 9-10% loss, as they are more efficient than roller/tyre dynos, since they do not require tyre interaction with the rollers causing friction and tyre deformation etc.
Using the above would give a bhp figure around 725, which is still well above claimed, but not the 100 or so first noted.
That said 700+ hp is still pretty damn impressive.

Lacking speed would not be the right turn of phrase. This is a monstrous power unit let’s be clear.

However reviews at the time were all lukewarm this side of the pond with most disappointed that the V12V seemed to be compromised in its development. Pegged back due to the gearbox (higher rated unit could not be engineered into the package) and in fact the car ended up weighing more than the DBSS which got the full fat engine.
I believe the review in question was Sutcliffe’s video and written review in Evo. Catchpole and Metcalfe also made similar comments. Journo views are not everything but I was disappointed at the time of release that there was no rave reviews.
Where did the 472km/h come from? HiTech quoted ‘in excess of 400km’
Still fantasy though. I have an eMTB. It has a 34-tooth front chainring. It’ll do about 20mph on the flat. If I put a 136-tooth chainring on it, it has a theoretical top speed of 80mph. How credible do you think I’d look if I claimed I could get 80mph out of my bike?

I’d find it quite credible if you were free-falling out of an airplane on it from high altitude.Thank you all for your wonderful comments.
I was at AM factory in Gaydon seeing the wonderful Valkyrie being built. They told me I had a very special car tweaked to that of the DBS Superleggera and DBS 770 Ultimate (770hp) and also the AM Vanquish (834hp), as these cars had a 9.2 to 9.3:1 compression ratio and my one is 10.5:1 meaning it had the capacity higher for higher horsepower and torque numbers (which is what is achieved). Maybe taking the limiter off it goes right through to 8000rpm without damaging the engine (don't know).
The AM Valkyrie has a compression ratio of 13.5:1 and a final drive ratio of 2.91:1.
The 472kmh is at 6800rpm (theoretical speed per what the tuner gave me) whereas the 400kmh is at 6528rpm, which is what he published. Don't get hung up on this as I don't think it could achieve these numbers either.
I have driven the DSS Super and my Vantage feels faster than that, and when having a race with a new GT3RS out of the corner I blew him away (it was a bit embarrassing) and at lunch he said he had floored his car. That's all I can say. If you want to keep bagging the car up to you.
I also spoke to the tuner again and he said it is a very special car that produced wonderful results.
At the end of the day I am very happy with the car and that's all that matters. I can speak with authority as I have owned a number of high end supercars and she is very fast indeed. AM understated the numbers.
Thanks and enjoy your day.

Please think before you post figures…
If your car has a theoretical top speed of 472k at 6800rpm, it can’t also do 400 at 6,528rpm (unless of course it has a variable final drive ratio…
)
Your car has 641.7bhp at the hubs. With a hub dyno’s loss of c. 10%, that equates to a flywheel bhp of 713. Mighty impressive in any car, but certainly not 770bhp.
I’m not surprised you saw off a GT3RS - you have nearly 200bhp more
I’m not bagging the car (whatever that means) - I’m sure it’s absolutely epic to own and drive. I’m just questioning some of your ill-considered claims.
If you’d posted on here to say “my V12V has just been dyno’d at around 700bhp” we’d all be green with envy and glad that it’s making at least book figures (VH2 cars often didn’t make the claimed power)

Nigel has the right idea.
either it's a stock V12 vantage producing the hp it should, or maybe a bit over factory claimed output OR it has a tune etc, but the numbers still make no sense.
No on is complaining abotu the car. it is an Epic car, gorgeous, powerful, I can only imagine how it is to drive having driven a DBSS and a prior gen V12VS

Thanks Nigel all good. It is what it is.
I was using the roller drive train loss at 15% (which is fairly standard) if you say a hub is a 10% loss then I am fine with that.
I presented the numbers as they were presented to me. I thought I would get a bite on the top speed!!
There is one printout on the HiTech facebook page where you took the screenshot from.
Thanks Paul

Also and I checked with the tuner because of the higher compression ratio at 10.5:1 and referring to the graph HiTech posted online the horsepower and torque curve keep going up and does not taper off.
The tuner agrees hence I estimate at 7000rpm wheel horsepower is 660hp plus at a 10% drivetrain loss is 733hp at the crank plus and torque would be about 836Nm at 3000rpm.
I am interested why other Vantages did not get their required numbers.
I recently test drove the Ferrari SF90 (1000HP) and I can say the Vantage is very competitive, although the Ferrari wins especially being 4WD.
Check this out on the Belgian F1 track in the AM V12.

When I was at the AM factory in November they told me to hold onto the Vantage as V12 will be finishing in 2028. They also told me in writing my Vantage was one of 65 RHD in the world.
Thanks.
