Maptun crack 400hp for T8 tuning

Here’s one for the hi-po buffs.

Maptun have broken the 400hp barrier on a T8 tuned Saab 9-3 2.0T. The car is actually a 2005 Saab 9-3 but it’s been updated with 2010 panels and lights for the front and rear.

I love the carbonfibre detail work on the front there, too.

Enough about how it looks, though.

From the Maptun website…..

MapTun Performance is proud to claim the performance crown in T8 tuning – The magical 400 hp limit has now been broken.

The test car, a 2005 9-3 Aero equipped with our Quaife gearbox, reached an impressive 415 bhp and 450 nm of torque in our Rototest facility. A lot of time and effort has been spent fine tuning the software to limit the torque to a level that is suitable for the setup.

The car will be driven to England to participate in a trackday on the redesigned Snetterton Cirquit the first weekend of March. There it will face strong competition from Porsches, Ferraris and other supercars. In other words, a great opportunity to put much more expensive cars to shame. You will be able to follow the whole endeavour on the upcoming Maptun Blog.

It’s good to see Maptun planning for a blog to keep people up to date on the their latest products and achievements. But that aside…..

Performance like this doesn’t come easy. The list of engine changes is considerable….

  • Maptun Individual software
  • GT2871R
  • Tubular exhaust manifold
  • 630cc injectors
  • Maptun IC
  • Maptun inlet pipe
  • Ferrita downpipe
  • JT 3″ catback twinpipe
  • Wössner pistons
  • Maptun 450 Nm clutch
  • Quiafe 6-speed gearkit

And that’s before you get to the cosmetic/aero changes. There are still more changes to come, with upgraded brakes and interior being added to the car soon.

Keep an eye out for that track day video. I think it’s going to be a cracker!

Is such a setup unreliable in the long run, undrivable or why is it not directed right into the Saab product portfolio as a M3/AMG/RS contender? 😉

Amazing! And that front end looks great, the cf isn’t too flashy, nicely done.

I can only imagine that much torque in a front wheel drive car. I’m surprised they didn’t put this tune in a car with XWD. I wonder how much torque the XWD system can handle?

It’s been done before… I think… I believe it was a forerunner to the current Haldex system that was in Per Eklund’s 2000′ 9-3 Viggen (750 hp) when he won Pikes Peak.

A bit off-topic maybe, but if they put 2010 rear lights on a 2005 9-3, is it possible to retrograde a 2010 9-3 with 2005 rear lights ? Or do you have to replace body panels also ?

Yes, the ’08-current clear and ’03-07 lights are inter tangible. Both are the same size and it is just a simple job of unbolting the old ones and bolting the new ones in. Here are a couple links to Saab forums on this matter.

However, if you do that you loose the rear reflectors. In some countries it is illegal not to have those.

Love maptun’s work. How subtle is this car????? Congrats guys, a true wolf in sheeps clothing.

Very nice car Fredrik.

I love the carbon fiber stuff. Still thining of adding some of it to my car, but first the hirsch spoiler.
The brakes look sweet too! I have stage one in my 09 xwd and it has made such a difference. The torque difference is insane, especially in the snow!

400hp is alot, especially on a FWD. I can´t imagine how to dispose all that power without a limited slip differential. The engine itself, if put in perspective to the Maptun 325hp version, the main difference seems to be injectors, tubular exhaust manifold, custom inlet, turbo and of course software. Surely there are some more tweaks to it not mentioned in the list 🙂 BTW, anyone got a great deal on a lsd, let me know.

I do not like it. i just can’t understand limitation of torque on manual, especially on Quaife gearbox,

Fredrik2@MapTun
Guest
The torque is limited because of the clutch that’s currently fitted to the car. It’s not specified for more than 450 nm. The rest of the setup can easily produce another 50 nm without skipping a beat. We’ll keep it at 450 nm for the time being. We don’t want the clutch to slip during the trackday. The dyno charts show wheel horsepower – divide by 0.9 to show crank horsepower. Just in case anyone was wondering. Another clarification – the gearbox is of course fitted with a Quiafe LSD. If anyone feels that there are questions that are unanswered… Read more »

Fredrik, when will we see Maptun tuning for the new 9-5?

Slightly off topic: Any experiences with the Quaife LSD? Will it help improve pulling horse trailers on muddy fields? Will it help on snow-slippery roads? Any match to a real AWD? Are there drawbacks?

Thx for any input 🙂

Fredrik2@MapTun

The LSD definitely helps when the conditions are slippery. It will essentially prevent the car from becoming “one wheel drive”. With a regular open differential it’s easy to get stuck with one wheel spinning and one wheel stationary. A locking differential, the kind you find on true terrain vehicles locks the wheels together completely. If one wheel does one revolution the second wheel does one as well. A LSD, or limited slip differential, locks the wheels together but allows for some slip between the two, hence the name. You need to be able to have the wheels rotating at different… Read more »

Somebody said once here, that after he mounted the LSD on his OG9-5 the TCS was less active on slippery conditions.
Is it true, that a LSD takes, in some amount, over the job of the TCS?

So, why do almost no car manufacturers offers those LSDs, even if only as an option? There must be drawbacks, I would guess?! Or do they just not want to be confused with LSD dealers (and stranger things have happend) 😉

Great job, but it should stay on tracks.
Supertuned cars are could face issues passing the annual mandatory checks. And in case of an accident I am confident that that if the power printed on the cars ID paper differs 100% from actual power the driver could be in a situation that is unfavourable for the owner.
With Hirsch “modest” tuning You get new paperwork from the government. So the car is 100% legal.

Other “modest” tunings are also legal, I can’t see the difference…

Mr Insurance Man obviously has some words to say, but that applies to Hirsch also.

“Modest” tuning is not allowed in Sweden.

Mr Insurance will notice that the car have undergone a new registration and that it is completely legal. Therefor Mr Insurance will continue to stay happy.

Kudos to Maptun for this, T8 cars really can handle more torque and bhp than you think! 🙂

Hi Fredrik,
Really Nice Work! Congratulations!

Long list of changes but from the description it appears that you have not changed any of the internals besides the pistons. Is that true? If yes, then this means that the engine internals and the block can withstand 400-450hp.
What about the engine cooling system? Did you have to upgrade it or the stock one is sufficient?
Is the intercooler an FMIC one?
BTW, do you happen to have available any performance figures for this car? i.e. 0-100km/h, 80-120km/h, top speed, etc

Fredrik2@MapTun
Guest
Thank you, Chris! You are correct, only the pistons have been changed. Nothing else inside the engine has been touched. Nothing has been done to the cooling system. We haven’t had any problems in the Rototest (where it’s usually 35-40 degrees C). We’ll see what happens when we push the car on the track but we don’t foresee any problems at this time. The intercooler was changed during the last tuning session to the new Maptun IC. Inlet temperatures dropped by 25 degrees (to ambient temp), power jumped by 30 hp with 0.2 bar less boost. It’s a really good… Read more »

Not even an extra oil cooler?
Hmm, what is the size of the Maptun IC, Fredrik? What is it’s width?

very good looking 9-3ss, do the new wings etc just bolt on or is major fabrication required?
