996 TT ever heard of one going pop due to tunning ??
Discussion
As tittle suggests really, just wondered if anyone has heard of any engines letting go, due
to tunning upgrades etc ??
Poss considering going down this route at sometime, and although i may be able to swallow
the invalid warranty issue, it would be easier with the knowledge that such things are very rare ??
Thinking of a Revo type thing, as i like the facility to switch back to normal for OPC servicing etc, and when the missus
drives it

Hi
Never seen 1 go pop with either techart or DMS power upgrade..
very good upgrades both DMS is a little less agressive than the techart one but not as expensive either.
TT engines are very solid lumps.
only seen 1 engine failure and it was the end of a camshaft broke off...weather it was fatigue or not dont know.
all sorted by an OPC FOC!!

Cheers,
Forgot to ask whether any probs with the turbos either ???

Hi
never had problems with turbos either, a couple problems with 993 turbos cracking and leaking oil into the turbo through the spindle shaft.
Have fitted oil valves to the tops of the turbo oil intake but these are standard on 996tt anyways so all in all no problems ive come across.

Mine went pop without any mods., at 28k 4 years old, I had already sold the car to an OPC, it had oil work done a month before, so could have been down to this, was covered by warranty for the new owner.....BUT if it had been modified & not covered the £££££££ would have been a nightmare!
Much as extra grunt appeals remember every force has an equal & opposite force, if you increase the power output of your engine, it will wear quicker, is more likely to fail, will affect your re-sale value! Ok it may take many miles to show any variance over standard, but some future owner will pay for a max boosted car!

Tests have been done and if the power upgrade doesn't destroy the engine by itself (i.e. a proper Porsche tuner kit) there's a direct link between the wear and burnt fuel, two exact same engines, one will suffer increased wear if under a higher load therefore burning more fuel. This will be true for a tuned engine which will increase its fuel comsumption by say 5%, theoretically it won't do 250 000 kms (like Pierre's - a fellow 996 Turbo owner) but it will do 237 500kms instead.
Now the tuning package itself... I apologise for all the others who already read my previous posts saying this but I really have to.
Please do your homework and research on forums like Rennlist, Rennteam and here on who are the right companies to tune your P&J, FYI there's only a handfull of persons in the world (2 or 3 in the US and 3 or 4 in Europe) who can properly tune a 996 Turbo which means playing with dozens of the 2700 maps available in the stock ECU which you need to have access first and test this on an engine bench not just playing with fuelling, timing and boost in a road rolling dyno (sometimes even without rolling road, just tinkering with the figures on their computer screen). So don't go cheap, don't be lazy (handing over the car to the nearest "XXXXX" dealer). Please respect people like RUF, Techart, FVD, Manthey, RS Tuning which spend hundreds of R&D to develop a complete package not just a "re-map" Play n' Go sold for £999.99 with 10% discount if you bring a friend to tune is Mondeo as well.

Surely it depends on how much power you are going for? For a little more boost I reckon people like Revo etc are perfectly adequate. Its when you start pushing further you need Ruf/RS tuning etc i.e. engine is being opened up for strengthening.
I wouldn't personally bother with a remap on an NA either, which again means you are back to your Manthey's/RS tunings etc, but NA power is much harder to liberate.
Glen I wouldn't even worry about the turbos, you can get reconditioned ones for a few hundred quid in the unlikely event one fails. I suspect the 997 turbos might be rather more though!
Only question I'm not convinced on is whether the factory can detect the reflashes on the ECU. I have never been totally convinced on this one...

Dan,
Even for "a little more" boost I wouldn't go to anyone but a proper Porsche tuner (and I didn't). The 996 Turbo internals are good up to 600bhp (so they say) and theres a lot to be done in between without opening the engine just like the incredible difference "a little more boost" software from a proper Porsche tuner has from a generalistic remap company.

You may be right, but if the maps shit you can just take it back for a refund with most of these places. I'm just not sure mapping is as big a black art as you make out, and if it runs properly under partial loads as well as full throttle, and across all temp ranges its good enough imho. If there are flat spots or it won't start when warm then get your refund. With the german stuff you are paying quite a premium for the TUV testing they have to put it through. Thats obviously a good indication of quality but surely it doesn't mean everyone else is crap?
Look at the cost of the Manthey K400/410 upgrade on a GT3. Its over 10k euros IIRC and all you get is an exhaust, air filter and remap (possibly on a new ECU). Its good stuff, but boy is that a lot of money for those parts. Isn't the cargraphic RSC 3.9's engine RS tuning designed? The last review I read of that said the map had some flat spots and didn't feel so good at low revs. It won the tuner GP so is clearly quick and ok under WOT, but it sounds like the map could do with more work!

I hear what you guys are saying, but Porsche is well known for its engineering excellence, if the 996TT can run 520bhp without any issues they would launch the car with a higher output further distancing their competition, even the new 997TT has less than 500bhp..................why?
Now I understand that a manufacturer has to meet tough emissions & noise regulations, that a tuner doesn't, so a sports exhaust with racing cats can free up the breathing in a way the manufacturer can't, so this would add 25 horses. Beyond this turning up the boost pressure & raising the rev limit is going to increase strain & wear on the engine & chassis components. The GT2 is case in point, Porsche uprated the gearbox & clutch (etc) before releasing the car with bigger turbos & higher boost pressure (still a lot less than 500 horses though!!!!). How many aftermarket packages uprate anything other than boost & rev limit for 500 bhp conversions?
A 20% hike in engine output with no transmission/engine/clutch changes WILL (fact) wear & strain components more than a standard car, you as the first owner with 20-30k on the clock may not notice this, but future owners will, & this is one reason why I for one would not buy a modified car, beyond exhaust/cats/filter!

I think one of Porsche's reluctance to sell more power than they do is that they're concerned about what octane level of fuel is going to be put into their cars in different parts of the world. One (of many) things I've enjoyed since moving here 18 months ago was how easy it is to find 97 octane petrol. That stuff makes my 993TT very happy. It's *impossible* to find that anywhere in the US. You're lucky to find 92; in California premium means 91. Think about running that through a remapped motor. I emailed my old mechanic on arrival here (actually on the TT's arrival) and asked him if he thought the extra octane was necessary, given the price, and what the manual says regarding what's needed. He told me in no uncertain terms to buy the best (after all it was my money). I think Moosh's experience, on a different thread, was "bad" fuel in France made him think he'd lost a lot of power in a recent remapping. All his problems disappeared with the local stuff.
Personally I would leave it standard.
There seems to be more remapped 996TT's out there there standard ones, but I think the majority of used buyers will look for the safety standard cars as they get older, so remember the impact on the resale value. This will be particularly the case if a prospective buyer has never heard of the tuning company.
If you are going to do it at all, go mainstream !!
All IMHO of course.

because Porsche is a business like any other and engineers in obselescence so it can improve with each successive model. Also Porsche is run by accountant/marketing people more than engineers which is why the potential of Cayman/Boxster are clipped all the time. If the TT had 520bhp where would the GT2 go? Up that and it would be as quick as the £300k CGT etc. Would the 998TT be able to top this 520bhp 997 without a new engine block?
Agree with your general gist though, not sure I would chip a Porsche with Revo/DMS or suchlike who do not specialise in Porsche and I would not buy a secondhand that had been chipped by them
My tt was chipped by DMS a year ago and i can honestly say it runs better..not just quicker..than it did in standard form.With the standard ECU the car actually feels a bit restricted and lazy.With the upgrade there is less lag and it pulls a lot earlier and stronger,having said that you do have to treat the car with more respect as clutches/gearboxes etc are clearly having to work harder.Im sure if drag starts from cold were practiced regurlarly or the car thrashed up to the rev limiter all the time the upgrade would potentially cause damage compared to standard spec.The only downside with the upgrade is back tyres...nearly 500lb torque is not particularly rubber friendly.
