Hi

I used to own an 900SET but now i have a black 9-5 Aero 2000'. A total different car! The only mod. is ECU so i am now at 260PS. I would like to increase the power at about 280PS.
Would an intercooler and an intake pipe make this diffrence or is it waste of money?

If I were you I would install the larger turbo inlet pipe which feeds air to the turbo and upgrade the downpipe/exhaust to start. These are the biggest "bottlenecks" to be faced. The intercooler is a good mod to do but Hirsch's 280hp kit retains the stock intercooler which tells us it can handle the power level you seek. I personally am a fan of the open intake but some worry about water intake which is a valid concern to have. You will want to use common sense in avoiding deep puddles and WOT acceleration during heavy rain if you go with the open intake. I ran the open intake on my Aero for several months with no problems. I am also in an area that does not see great amounts of rain. Stay away from Abbott's design however as this makes water intake much more likely. Check the post about installing a BOV in this forum for details on installation.

Hope this helps. Good Luck!

Thanks for the reply.

The problem is that i can't get a cat with TÜV approval. So i would like to keep the stock one and do only the intake modifications.
As for the Hirsch 280PS vesion ,it has the upgrated intercooler and intake pipe but without the catalyst.

Whoops...thought I remembered the IC not being included in the 280hp package. You should at least do a CAT back exhaust upgrade. Dr. Boost gave some great info regarding exhaust gas temps getting way too high with stock exhaust and an upgraded ECU.

A potential problem with the intake mods is that during full throttle, the ECU stops adapting and is running on a pre-programmed open loop. With the greatly increased amount of air reaching the engine with these intake mods, the potential to run lean exists. Just something to think about....

Hmm..

I wonder if this cat is TÜV approved...

Unfortunately i can't find a TÜV approved cat. Hirsch do this but it is available only with the 305PS or 280PS version.

I think i' ll get the inlet pipe from Abbott and the cat back system from Hirsch (TÜV approved). I hope there will be an increase of the HPs and Torque.
