DB11 - DBS

[Gene G]

The DB11 and the DBS both have a 5.2 Twin Turbo V12. The DB11 has 600hp and the DBS has 715. Is the difference just a tune or are the fiscal differences? If it is just a tune would it be possible to download the tune from a DBS and upload it to a DB11? Really like our new DB11 but an extra 115 hp would make it epic. It doesn’t need and I don’t need it, but it sure would be nice.

One major difference is the cooling.

I believe there are also other mechanical differences to account for the additional torque. I hear this would shred the gearbox of the DB11 in it's "off the shelf" form.

There's some hardware changes that would make it an expensive job to port over from the DBS (I thought it used different turbos, intercoolers and a different version of the ZF8 box).

The DB11 AMR tune is probably easier to source (albeit only ~30bhp more) - that was more akin to a 'turn up the wick' via some ECU tinkering, but it was the chassis and suspension tweaks that made the biggest difference.

You don’t want to over-tax the DB11 engine

Indeed. You'll PAYE the price...

Gene, what you would need to do is speak to some experienced tuners of the DB11. There should be a few in th UK I suspect. I have no tuning experience of the DB11 engine and am not sure to what extent it can be pushed. BUT I have tuned several engines; usually you should be able to get substantially more than factory for little outlay.

For example a tuned twinturbo BMW N54 engine can be tuned to output +70HP very simply and quickly (within 15 minutes) from a flash tune on stock cooling. There is often headroom. Reliability is not an issue at low levels of tune. It also depends on how you will use your vehicle. Do you plan to track it? What are the maximum ambient temperatures it will see? Usually a good tuner will take all these things into account and advise accordingly.

As someone mentioned the AMR already produces +30HP. Did AM uprate the cooling in that version? How about the transmission hardware/software, turbo hardware?

Have a look at what the AMG guys are getting out of the V8 TT...+120HP with just a tune + downpipes on the stock DCT trans. Anyway to be quite honest, I'd imagine the Aston Martin V12 TT to be quite capable of more than +115HP*.

• Just as I finished writing that I looked at VelocityAP's website. Note this isn't without its inherent risks & not for everyone but .....apparently AM have 'heavily sandbagged' the DB11's performance to allow for future versions. +106WHP is achievable with just a tune on stock DP's! That's equivalent to approx +130-140HP at the crank which already puts you ahead of the DBS Superleggera. Just what you need Gene - brilliant!

The DB11 AMR tune is being offered by AM. It's just the tune though, none of the other chassis tweaks.

[Gene G]

I’m sure that AM left a lot on the table for future model updates. I had an E63 AMG Estate that was tuned by RENNtech it made 701hp and 839 tq. A tune can really have great results on tt engine.

Fiscal jokes aside, on a factory tour a couple of years back, our guide mentioned that the DB11 engine could potentially be boosted to 800bhp (I think he was plucking a number out of the air but the broad point remains). So I would have thought a tuner could easily get more out of the basic DB11 and as long as you didn't push it too far I would bet the diff could take it.

Mike at Bamford Rose is probably the man to ask

[dbs2000]

We've seen the AMG V8 already dialed up to 600bhp so the V12 will have a fair bit in the tank

I'm sure I read somewhere the ZF gearbox in the 11 was changed to an uprated ZF, to cope with the torque. I might be wrong.

8HP75 in the ‘11 and 95 in the DBS, so max rated 750 N m and 950 N m, respectively.

After doing some research the part# for the DB11 engine and the DBS are the same. So it is just a tune for the engine. There is some additional cooling and the trans is different ( stronger)
I will be keeping mine stock for now. As it gets older then I will probably make some changes to it.
