Update:
With a pretty simple setup with the HKS EVC 6 (Fun 5 mode RPM/throttle) i now boost up to 26,5 Psi and drop to 24 at 7000 RPM.
I guess the full exhaust system will greatly prevent from back pressure.

Mike .. question for you guys ..
When you fitted your IC 3.5" .. did the car lean out ??
I checked mine .. and it didn't .. infact .. it ran richer .. ???????
Which brings me to another point .. another forum guy lost 20hp switching to a bigger IC (no names) .. doesn't sound logical but it happened (operator claimed its the poor FMIC design)
Care to explain how that is possible ?? (basically extol the good designs on the ETS FMIC please
)

)Here is some discuission.
Because of the additional Airflow, the car will run richer based upon Airflow Map, which really richens the car up in the higher airflow areas. We observed that with the IC, the car made a max of 17hp over the stock unit, but there was a spot at 5700-6200 that the power dipped down to stock IC levels. This dip is when the car richens to 9.8 AFR. The reason that the car gets so rich is because of the increased airflow past the MAS. If it wasn't for a greater air density, the car would likely sputter out from being so rich. With the 4" cooler, this dip was less pronounced, and we feel the reason it is less pronounced is because of the greater air density ( more oxegen ). This brings us to how an inferior IC could cause a loss in power.
If an IC is really free flowing, but not efficient it will likely run very rich and possibly have spark issues. A good example would be an Ebay style core. These cores have internal fins that flow strait through. (You can actually see daylight through these units). If this kind of core was fitted to an Evo 10, there would be alot of airflow as observed by the Mass Airflow Sensor. When the computer sees this high airflow rate, it will inject more fuel and make the car run richer, just as we observed with our intercoolers. Now if the intercooler cannot cool the air well and increase the density, then the oxegen content of the charge air will be low. Because of the low oxegen content, and and the high airflow rate past the MAS, this make for a very rich situation in wich the car could make less power, have a sputtering issue, or most likly be on the verge of spark break-up and just have really choppy power. This is what our speculation would be if a high flowing, low efficincy cooler was fitted to an EVO 10.
Things that can contribute to a highflow / low efficiency unit are:
Low Density Fins
Small Size
Short Tubes
Low heat transfer area
Combinations of above
Hope this helps

I'm hoping tomorrow! The car should either show up today or tomorrow.
