V8 Vantage engine

[Patrick Bateman]

Aston Martin V8 Vantage: 4.3L V8=380BHP

Ferrari 430: 4.3L V8=490BHP

How much do you think it would cost to get a tuning shop to tune the Vantages engine to the same power as the Ferraris?

If it didn't cost to much then you would have an almost perfect 2 seater sports car.

aaa, you see, aston decided that v8 vantage's gonna be the samllest so it has the samllest amount of power, vanquish S = 520, db9 = 460, v8 vantage = 380.
380 is very little, so the car is wrongly named as "Vantage", it shouldn't be named like that

[Xeon SX]

u want to say that the only better thing in 430 is the engine?

[AML]

430 can't be compared to the v8, the closest aston is the vanquish s

[GraemeH]

It's hardly as simple as saying it's the same displacement and arrangement so it'll take the same power.

The ferrari engine is built for the power it has and the aston is built for the power it has.

It should be named Disadvantage.

No it isnt.

Jeremy has said a few times that the Vantages engine is delibrately less powerful than it could be to insure it doesn't jump up and down all over the DB9. So the engine is capable of being perhaps a lot more powerful.

[AML]

thats because aston is making too big gap between powers of engines, 520 > 460 > 380.
i think it should be 520HP (vanquish s) > 470HP (db9) > 430HP (v8 vantage)
solution like that would be simply better

the engine itself is based on Jag's V8, you could supercharge for bit more power. but it still wont be as good as the 430 though

[AML]

but again aston seems to avoid superchargers these days

back to twin-supercharging!!!

The point im trying to make isn't whether the Vantage is a better car than the 430 i was using the 430s engine as an example because it has the same displacement and arrangment as the Vantage but produces a lot more power. Since we know the Vantage isnt doing all it can engine wise I was just speculating how powerful it could be. Also there would be no supercharging or turbocharging aloud since that changes the engine from the ferrari one. Only reworking the management system etc would be allowed.

[BerserkerCatSplat]

V8 Vantage: 3460 lbs, 380 HP 9.11lbs/HP

F430: 3197 lbs, 490 HP 6.5lbs/HP

Now, the stock Jaguar supercharger adds 33% more power to the standard Jag V8, so if we apply that figure, assuming the Eaton supercharger weighs 40 lbs:

V8 Vantage II: 3500lbs, 506 HP 6.9lbs/HP

So, even with the supercharged engine, the V8 Vantage still has a poorer power-to-weight ratio than the Ferrari.

Aston Martin, however, had a 600HP twin-supercharged V8 in the last V8 Vantage. The technology's there, they just won't use it.


Edit: A "tuning shop" wouldn't be able to make Ferrari power, no matter how much money you threw at them. You'd need a revised intake, different cylinder heads, headers, all that sort of stuff. Redoing the engine management would do little to approach the Ferrari's performance numbers. The easiest way would be to supercharge.

I hope you are only considering power, because they are in completely different classes

[AML]

they are all completely different class
430 can be compared to ford gt, carrera gt, slr, koenigsegg and other supercars

Wouldn't say that I agree with that. I agree that the Vantage and 430 are different classes, for starters the 430 costs about twice what the Vantage costs, but would put the 430 and Ford GT together, the SLR and Carrera GT together in a higher class and the Koenigsegg in a high class again.

That was a 5,3 Litre V8.


Allthough, Callaway managed to get 740hp out of it for the AMR1 Group C racecar, without forced induction.


Of course the Jaguar unit in the V8 Vantage needs some serious workover to get above the F430, but it's not impossible...

there you have it

if it were a sprint car, they even would've made more

you can't compare a race engine to an engine they sell to the public

[Hollis]

Anyone heard of Cosworth engineering? They did the workover on the V8 in the vantage, and Aston Martin does have a works service for a reason. They specifically state that if you want your car tailored exactly to your specifications they'll do it (I.E. give you a 450hp V8 Vantage), and you can even tell them how you want it done. Knowing cosworth and AM Works, you could definitely get a reliable 450hp out of that V8 as a minimum.

I don't think the engine is the problem with the vantage's performance, It's just a heavier car than most performance cars. Blame it on the chassis or the luxury but it's several hundred lbs heavier than the f430, and even a corvette.
