DS3 THP Sport Chic Blanc Banquise / Noir Onyx

[Fabian]

So, today was the big day.
Went out this morning at 8 AM to place the new intercooler.

First started to remove the "old" intercooler.
Needed to remove the front bumper, the headlights etc.

Old one removed:


Difference between Old and New:


New one on his place:




And now the new looks:




It was a long day, but am complete satisfied.
Think it gave some good extra power and torque, It still remains a very smooth power delivery, but he keeps pulling through. :cool:

[Fabian]

Herewith also two pictures from AutoCad with the difference between my intercooler and the forge one

Forge Intercooler (Dual Pass Intercooler):


My Intercooler (Single Pass Intercooler):

As you can see the air needs to make a longer route in the forge intercooler and is less cooler because it gets warmed up again by the incomming air.

[cyclone]

The Forge design is undoubtedly a compromise between efficiency and ease of installation for the average guy and would still be an improvement over the factory intercooler.

[Fabian]

Yes, offcourse it is and it is not bad at all, but I was searching for better solutions and especially a cheaper solution!

[Fabian]

Saturday the 18th I'll do a new rolling road run to see the "improvements" with the new intercooler!
Think there will be some good gains!

[chiefnerd]

Be interested to see what the intake temp difference is. Are you running a remap?

[Fabian]

The difference is around 30 degrees! Not running a remap yet.
Will post the differneces in power coming Saturday when I have a new rolling road test with the new intercooler

[chiefnerd]

I would have thought about a 6-10BHP gain and maybe 7 lb/ft torque. The big difference is when they remap it because the turbo can be cranked up much higher because of the lower intake temp. My guys reckon I should get 210-15 once I get the new custom intercooler fitted.

You'll have great fun on the dyno though- always nice seeing your own car up on the rolling road and being able to listen to it first hand

[Fabian]

So, bin to the tuner yesterday and results are as following:

Power at the wheels
157.5 hp @ 4688 tpm
289 nm @ 2727 tpm

Power at the crank
173.8 hp @ 4688 tpm
310nm @ 2727 tpm

This means no chnage in top end power and about 12nm extra.
Besides that, there is some more torque in the middle rpm range and more hp in higher rpm's!

Spoke to the tuner and he advices a couple of things.

First change the standard (plastic) blow off valve for the (alluminium) Forge one.
The forge one can be adjusted with different springs to match the boostlevel of the car.

Second thing, change the exhaust for a larger diameter.
Exhaust is now the most restrictive part and also obstructs the intercooler to give the full advantage!

Also do the PCV delete and place an oil catch tank for the second PCV outlet.

Have you decided which exhaust you are going for yet Fabian? (Your car looks great BTW)
Extremely tempted by the BASTUCK one myself (No mid silencer) - in talks with a supplier/fitter in Southampton UK at the moment.
Knowing me I will take a while for a think

[Fabian]

Thanks!!

Yes, for me it's still the Bastuck one!
Think it will be next year, and then also do the Downpipe.

First want to change the wheels and go for the Bilstein B14 PSS Coilovers!

[Fabian]

Last week I ordered the Forge Recirculation valve
Received a message that it was posted yesterday, so hopefully I'll have it by tomorrow.

Will post some pictures and thoughts when I've fitted it

[Fabian]

As promissed herewith some pictures from the Forge Recirculating Valve.
Fitting it was very easy and took me about half an hour.
Because I don't have the standard filterbox anymore I've fitted the "solenoid" on a different place then what the fitting instruction describes.
(you can see the solenoid on the 3rd picture on the right side!)







What I think about it:
The blow-off sound you now only hear when lifting throttle after hard acceleration.
Personally I like this, because the car gets more quiet when driving!

Also I think there's less Turbo Lag after shifting gears.
First there was a slight hessitation after shifting when accelerating hard, now that's gone!

Over all I think it's an good investment advantages above mentiioned and It's more reliable :cool:

[Fabian]

Small update for today!
Finally received my 3D LED rear lights :cool:

Fitting them took about 10 mins, so that was very easy!

So, 1 pictures says more then 1000 words.....

[marioiturri]

Fabian,

How did you get the little R from the DS3R logo?
And what did you use to get the lights on the car plate white? LEDs? if so which ones?

thanks !
