QUOTE(TOJ 123 @ May 4 2008, 10:05 PM) Have you changed downpipe/exhaust etc.? Downpipe of 76mm without the pre-catalyzator. The rest till the and of 70mm. Air filter HSK super hybrid one (http://gruppe-s.com/Evo/evoeng/hks_sfilter.htm)Bigger Intercooler is what the Greek improvers claimed also during a discussion.

QUOTE(TOJ 123 @ May 18 2008, 10:48 PM) Evolander, have you tuned yr car already or waiting? Tomas not yet, but I drove Botzos car on saturday!!! I already bought a second hand intercooler of an evo 9 and I'm about to have a second hand of full set of evo brakes (brembo the front ones). I didn't make a final decision yet as of the remap. Reverting.

Hello Botzos!
Today we had really warm in Sweden and of course car is running really ok but a dramatic change to let´s say when we have 15 degrees and even better of course when we have cold temp.
So it can be one difference to performance as we both have been into. I know for sure that my car drops easily lets say 12-18% when really hot.
If I compare to turbo Audi A4 1,8 T+2,0T and S+RS versions, Volvo S60 R, SAAB Turbos, Porsche Turbos, VW Passat Turbo petrol+diesel, Subarus, EVO:s Mitsus etc etc which I either have had or tested they DON`T react as much as this car on warm weather. All tubo cars and others reacts on warm days where oxygen mol. is less/dm 3 but this cars reacts heavily on this warm weather.
From my point it goes so far that I even don´t want to race or push the throttle because of disapoinment of the cars performance....a warm day.
Trust me, I don´t want someone to challange me these days since I know that cars that I for sure would beat at under +20 I will loose against at +28 degrees.
I have asked those who really knows Turbo engines, PRO:s, and they always answer that : " all turbo cars runs worse in hot weather".
Though I do NOT agree since all Turbo cars I have had have MUCH bigger Intercooler than our cars AND do NOT react as much as our Outlander on warm air. For sure it has to do with to small IC. With great interest I will follow if someone has positive report about great working bigger IC without lower response.

I believe the Front Mount InterCooler (FMIC) can be of the same volume as the original TMIC and the performance will be better with not increasing the turbo lag. One thing is size of the intercooler but its position and cooling-air flow-rate are important as well. First: See the "sectional surface size" of the air inlet (hole) in our bonnets. It is equal to approx 10cm x 20cm = 2 square dm, am I right? So regardless from the FMIC size the available air flow rate is limited by the hole size. Second: Let's have IC of the same inner volume (cca 4 liters), one with lets say 40x15cm = 6 square dm surface. Yes, the original FMIC is about the same surface size. But if this second 40x15cm IC is mounted in the front bumper's air-dam exactly perpendicular to the air comming through the IC, then those 6 square dms are cooled better with much greater (at least 3x greater) mass of air. And this FMIC does not suffer by heat comming from engine bay when the car waits for green light... Third: The mass of air flowing to the FMIC is allmost not affected by the aerodynamics of the moving vehicle. I would bet that the airflow comming into the bonnet inlet for the original TMIC is seriously damaged and diverted by the aerodynamic effects at the front of the car. You know for sure what I am talking about. And if you don't, read this article. So the mass of air comming into the 2 square dm big hole is even smaller, means even lower air flow rate and even lower TMIC efficiency. I plan to change the TMIC for not big FMIC and to use the original inlet for TMIC as an inlet of cool air for the engine. The air will be under some small pressure right since entering the inlet system, means some extra boost even when turbo is not spinned-up = a bit less turbo lag. But first I have to solve the problem with air filter placement and separating water from the air sucked in...
