DS3 155 I like to change to about 270hp

[Ulrix]

I have mounted a Forge intercooler and put in a Chip from Promotech but it did not give more than 192hp. I have bought a DS3R turbo and uppgraded it with bigger compressor turbine but still it is bolt on. I will also put on Cobra Sport Race cat + de cat system.
I am qurius about Albish projet with new pistons from Wossner and Mahle Conrods. I can find that many talks about Jamie at JS but my car is in Sweden and I have problem to find any that can Remap my car. I wonder also if any one have idea about cluch.

Som pictures when I mounted the Forge items.

Hello and Welcome again Ulrix,

This seems like and ambitious project, I would love to see how it goes And heres my two cents on it:

Speaking from my experience with the Racing I had a Chip Tune which was tunable to 270hp but it could never reach it, set at the maximum tune it could only reach 258hp@6300rpm which is pretty much useless, so I did drive it with the chip's 80% tune, at 247hp@6000rpm. So, 270hp with a chip won't be possible you will need a remap for that (supposing you have all the hardware).

Even after the rebuild, the tuner how is doing the remap said that 260-ish bhp would be more acceptable and 'safe' to run. And that made us think into modifying the turbine compressor wheels (billet, which does not give more boost, it's just more reliable at higher boost levels) about 1.4-1.5Bar on stock turbo, and custom exhaust manifold both will be made at a garage who manufactures drag parts, but more on that later...

I'm aiming for ~240hp@4800rpm so close to 300hp@6000rpm on 100RON fuel...

P.S What kind of 'bigger compressor turbine' did you use? do you have any pics?

Cheers

Seems very ambitious to me also...that is one hell of a power hike just by essentially changing the compressor wheel and relying on a 'chip' for the tune!

In my experience (with my Subaru WR1), there are three fundamental variables...AIR, FUEL and SPARK. So nothing too complicated. However for that increase in power you are going to be pushing the standard parts to the limits, and probably beyond. Even the R1, R3 and R5 rally car kits have upgraded engine internals so I would have a look to see what parts they change and follow suit.

With a bigger blower, comes more air, with more air you need more fuel. So more fuel means better fuel pump and higher flow injectors. With a better bang, you now need to control all those forces with new forged pistons, rods and bearings...maybe even new head studs too.

You also need to control the temperatures, so larger FMIC and a better exhaust system.

The last, and super important aspect is a definate need for a custom map. Do not rely on an off the shelf chip...it is your own parts, your own car, your own build. An off the shelf chip will simply not know anything of that and you run a high degree of risk to damaging something.

A rolling road, or a road mapping session is critical for getting the fuel map correct and dialling out any engine killer - KNOCK..or detonation. If you can't get a mapper for your car - then go to a proper ECU...there are lots of rally people up in Sweden like here in Finland. So finding people who know how to map GEMS, or MOTEC for example would be pretty easy I would think. Not even sure what the real rally cars use, but my bet is on the Motec.

I wish you all the best though and I hope you get what you are looking for.

270bhp, not really feasible for a private owner

Something will certainly break in the engine unless you change pretty much everything in and on the engine

Just buy a 270bhp car?

Bit easier, and less costly in the long run

However: Good Luck :-)

Caveman and Chris are both right, and the figures I wrote below are strictly for race use (hill climb and drag) so the car will not be operating on those conditions for more then 5-10 minutes (and under the help of WMI & Race Fuel) I will be running my car at ~250hp daily!

About the power tho, we did 'study' the Vone Racing approach on DS3 engines, and they seem to get pretty big numbers on their cars. So, according to their results 270 is possible, they did a 320hp DS3 THP 156 which I've been following the work on, the car ran 50 000 km on 280hp and after that got the bigger turbo (K04 Stage 1) and went to 320hp!
Here's the mods from their website (they're in french but understandable)

168 cv @ 320 cv
- 278 N.m @ 410 N.m
Config moteur :
- Kit d'admission FORGE / ITG
- Tubulures renforcées FORGE Motorsport
- Échangeur gros volume FORGE Motorsport
- Dump valve à piston FORGE Motorsport
- Turbo Hybride Créa-Racing
- Arbres à came spécifiques Leny-Competition
- Ligne complète Milltek 63,5 mm
- Dé-catalyseur Milltek
- Bougie NGK iridium Rcz-R
- Traitement Tri-Dan ( injection / moteur / boite )
- Huile Tri-Dan spécifique THP
Tarif pièces et MO : 5499€ ( Même tarif que le stage 4 )
Config boite :
- Embrayage Renforcé DS3R*
- Volant moteur renforcé DS3R*
- Pont court 16/59
- Différentiel glissement limité FAM ( avec tarage piste )
Tarif pièces et MO: 2399€
* hors VM et embrayage renforcé qui sont de série depuis juillet 2011
Châssis / Freinage :
- Combiné Blistein B14
- Elargisseurs de voie 16mm Av/Ar
- Étriers Brembo 4 pistons DS3R / Disques 323 mm
Tarif pièces et MO : 2499€
Total prépa : 10397€
Without the suspension and the parts that Racing already has the price would be around 6400 Eur (look at their Stage 4 offer for DS3 Racing)

as Caveman and I said before any of this will not be possible without a proper remap, a chip will just not know the setup of the car and would be no help...

And Chris, ofc I can get a 270bhp car but i really love my racing, and also the part of modifying it has its own pleasure, but then again in my case this is a car i will NOT sell so I consider everything a good investment


Cheers

Why is everyone just looking at the Turbo, exhaust, (dump valve) aftermarket intercooler and then a re-map ?

There is 60 + HP on the table, with a little knowledge, hard work and naturally hard earned cash, is nobody seeing where HP in an engine is produced ?

[Ulrix]

Thanks for taking part of my Projekt. I have now got the exhaust from COBRA and new TURBO. Turbo that is a OE TH03 for a DS3 Racing that are optimized. Check pictures. Longing for have som time to mount the items.

Not my field of expertise but I'm all ears (or eyes with this being the tinterweb)

HP is lost or gained in the cylinder head and its components, as I've already mentioned, there is 60+ HP to be gained from reworking the cylinder head and its components, yes it can be a little costly, and needs a good degree of understanding, that said, when I see what is spent on bolt on goodies, a couple of HP here maybe as much as 10 there, the costing' of the bolt on goodies can dependant on aftermarket brand, cost more than a reworked cylinder head with complimenting valve train components.

HP is lost or gained in the cylinder head and its components.

So are you saying purely efficiency improvements like (and my experience comes from playing Gran Turismo ) internal polishing or things like increasing the bore size or lighter pistons etc (again I'm dragging back memories of the above mentioned legendary game).

I'm starting to wonder if Czar is actually an expert on these engines or if his forté is in cryptography

I'm digging out GT when I'm home, i'l be an expert in no time ha ha ha

[cyclone]

jeez come on. stuff like port matching, porting the head, camshaft, bigger valves, multi angle valve jobs, stronger valve springs to keep the valves closed in high rpm high boost. The normal high performance head stuff.

But not everybody who joins a specific car forum knows that, in fact very very few would.
I drop my car a Jamies, he does some magic, I get it back with a significant boost in power for not a lot of (relative) cash, that's what most people are happy with.
