DMS ECU UPGRADE AND EXHAUST

[Colin Booth]

I have a 996 TT "S" and was thinking about getting the DMS Automotive ECU upgrade and exhaust too. I think that lot takes it to 550 bhp. As anyone had this done, what do you think, does the exhaust make too much noise ??

COLIN.

EVO Magazine tested a similarly equiped car a little while back and reckoned it to be the best thing since sliced bread.

I will have a look and see if I still have the article.

I haven't ot the DMS upgrade, but very similar - I can concurr the effect though, stunning

Thing that concerns me is the reliability issues. I cannot quite come to terms with the fact Porsche charge £9k for the factory X50 pack, taking the std TT from 420 - 450 bhp, and quoting such things as revised & strengthed Turbos, gearbox & linkages etc. So if a mere 30 bhp increase requires them to do so much work, how reliable does a 550 bhp conversion make the car? . Do DMS change the turbo's, play with the gearbox etc or is it purely the ECU or whatever thats remapped?

 

[lee fulford]

This has been my concern also..........Manthey do power upgrades and they're not cheap either.

Gaxor.....Have you lowered your car? I want to lower mine but not sure which route to take. My wheels have more (or less?) offset and I'm not sure if the arches would have to be rolles as well.

Feel I need to come in here. At DMS we have upgraded over 300 996 Turbo variants in the last three years without incident.

Porsche do create a superb car but their upgrades do defy some logic. The standard 996 Turbo runs KKK K16 turbo's. The X50 pack car runs the larger KKK K24 turbo's, larger intercoolers from the GT2 and the heavier GT2 clutch.

If you compare the replacement cost of comparable items from the 420 and X50 pack cars the cost are almost identical. Now Porsche do not put in the waste bin the parts that are upgraded on an X50 as they are never fitted in the first instance. I think if you accurately cost replacement parts out through an OPC then there is about £300 difference between 2 X K16's against 2 x K24's, 420 intercoolers againsy GT2 intercoolers and GT2 clutch assembly against standard 420 BHP car. The rest is down to the men in suits in the marketing department. Mr Porsche at the factory loved the X50 pack orders. He merely put another £8000 in the tin marked profit.

Our own 996 X50 pack car has run with hybrid turbo's, manifolds, exhaust etc over 640 bhp for the last 12 months and 10,000 miles incident free.Including many manic days at Bruntingthorpe.

Mike,
Appreciate the reply & I understand what you say about the profit tin!. I dont understand though why Porsche deem it necassary to change the turbos, intercoolers & clutch for a mere 30bhp. I presume if these bits are upto GT2 standards then there would certainly be no problems with fairly easily taking an X50 upto 490bhp as in a GT2 then.
I am not suspicious or critical in anyway of what you do, as I am sure it is not in you interest to have relaibility issues on upgrades, I really am just trying to understand how it all works. So do you upgrade various 'bits' of the car then as opposed to just remapping engine management etc?

Sorry for the delay in replying. With the X50/TurboS/GT2 cars they will run easily and very safely in the mid 500's without any problem whatsoever. We have standard 420 BHP cars running 530 BHP with ECU remap, exhaust and manifolds, On the X50 pack cars we run around 0.2 bar of additional boost and this certainly will pose no problem whatever with the standard K24's.

A typical example which shows what we do in context is with the Cayenne Turbo and Cayenne Turbo S.

From the start of production we had been upgrading the Cayenne Turbo by +70 bhp and +75 lb/ft.

The new Turbo S with the exception engine wise of bigger intercoolers is now producing approximately the same figures as our upgrade and the main thing Porsche have done is to merely run the car on different software.

Very often we are led to believe by the men in suits that there is a lot more besides but in reality there isn't.

Our own 996 has over the last month undergone some major upgrades which are producing very close to 700 bhp. It is only at this level of power have we upgraded to the likes of titanium con rods etc.

Hope this explains a little more clearly of the potential of these fantastic engines.

Cheers Mike....I may well be in touch before too long. Just picking up my X50 TT tommorrow actually, so you can bet given a few months of ownership I may well be up for a few more ponies & a bit of tinkering!!
