upgrading 996 turbo?

[jjcc]

Hi Porsche peeps,

My dad has a 996 turbo standard, which I am fortunate enough to drive sometimes. What a car! Just wondering about the x50 upgrade and the price for it retro fitted or what other performance upgrades are there. 40 or 50 extra german horses would be lovely if only a little extra dosh.
Any advice on best route to go for more power x50 or alternatives?

cheers

I believe the X50 pack retro fitted is around £8k.
Another option is an ECU upgrade from a variety of 3rd party tuners.

DMS for example charge £2k for their ecu upgrade giving around 500bhp.

The advantage of the X50 of course is it retains the porsche warranty. While DMS (& lots others) say thier chip is invisible to Porsche diagnostic equipment, I would assume all that was needed was a drive from a Porsche mechanic to realise that the car was not standard. So any warranty would be void & any goodwill claim that might have been offered would be out the window too !

that seems truly unbelievable value! anyone got this upgrade would like some owner reviews, a genuine 500bhp from 420bhp has got to be more than 2K!

cheers for the links will do some research, owners opinions are what I am after though, reliability etc.

cheers,

Loads of options out there.

I chose Miltek/Amd because

1 they were good value:-)
2 I had used them before on other cars
3 they could prove their product

If your are Southeast based, Ill take you for a spin.

Being very understressed I believe that the Turbo can take up to 500bhp very easily with no reliability issues.
having said that, part of the X50 pack includes fitting larger turbo's so Porsche seem to think its necessary, or maybe a way of upping the cost !!

You get what you pay for in this game. Ruf conversions cost what they do for a good reason. A couple of grand and 500bhp, no thank you. Did you know the 996 Turbo has the weakest conrods out of all the porsche turbo's....

[clubsport]

I understood the X50 also had steel synchros to help the longivity of the gearbox subjected to the increase in power.
I totally agree with the notion of getting what you pay for in Porsche tuning.
If I were looking at a second hand car that I felt was tuned on a high bhp / low £ budget I would run a mile.

[jjcc]

Spoke to DMS who claim they send an engineer out to you for a couple of hours remap the ecu, reord the original map so that it can be easily restored anytime to standard and for £1900 +vat you get a genuine 502bhp just from the ecu remap. You then go out for a drive with the engineer and if you don't want it he changes it back for no extra cost.
Sounds to good to be true, will let you know if we get it done. Thanks for the advice,
J

jjcc,
is this remap applicable to the X50 or the std turbo?
Cheers

The remap is appicable to both

[RoShambo]

so...in theory....you could have the remap done...then if the engine blows get DMS out to put it all back to standard before getting it to an OPC to be fixed....under warranty !

Can't Porsche access the ECU's history? Check what speeds, power etc were produced?



If nothing else, the DMS cars seem incredible value for money and im yet to hear a negative review

If Porsche so desire they can find out the date & exact time the ECU was accessed & what areas were played with.

To back Iggy up a bit, I had also heard a less-than-positive comment re DMS, so it may be worth taking Rico's 'nothing negative' comment quite tentatively. The jury's still out in my opinion, but I hope they are proved true to their word - 1900 GBP is great value.

A couple of points tho': I believe the standard, ie non X50, turbos are overworked at a true 500bhp and this can affect their longevity. AmD's rechip for Rich had 490 or so, which isn't apparently a problem. I'm sure 500 would have been attainable if they felt like it and would have been better for marketing purposes.

It should also be noted that as far as I'm aware, the DMS remap isn't bespoke to your car; it is a general map.

Pays yer money...

[MOD500]

Just been thinking about this, the turbos on the standard 996 TT are KKK K16's I believe which are the same ones used on the 993TT.....most tuners recommend using hybrid K16/24 turbos (i.e. more puff with least lag possible) when wanting 500 romping shires on the 993, how come the same thinking doesn't apply to the 996?

[domster]

Dunno; if they are hybrids they are not the same turbos anyway, may be able to flow more or have special 360 degree bearings or something. I was told that standard 996tt turbos are overdriven at 500bhp in a standard 996tt.

I had a long drive in my car last night and still cant believe how well it drives. I still havnt seen any more boost than .9 bar, which reassures me the turbos are not getting a kicking. Does anyone here have remaps from others see a peak boost difference?


The exhaust is ing loud as well :-))))

[charlie360]

The peak boost pressure that you see is also related to the atmosphric conditions/air density. You will see higher boost pressures on colder damp days. The nromal peak boost that I've seen is 0.9-1.0, although I have seen up to 1.1 on the odd occasion very briefly in the afformentioned conditions. My car has a west chip and a miltek exhaust.
