Airflow coming into to the air mixture bowl on CIS K jetronic has always seemed limited in its amount of flow and temp of air its passing in. Abandoning my attempt at just moving the filter and ducting to the the right side of the engine compartment which would not be of much significance anyway. While the two NACA ducts in the rear quarter windows are already feeding the water inter-cooler the next logical spot seemed to be the passenger window area. Location of the intake and filter can be easily moved so I can experiment with other locations. Took the car out around the block and terrorized the neighbors. Outside temps were in the 60's before this cold front and snow came in this weekend. Some interesting differences and sounds as well. Intake really resonates airflow feeding in when on boost, loud but this car is loud any way. Boost spooled up quicker. I have driven this car in cool temps before and I know the difference in performance that makes but this was not the same it was better more responsive.
On a side note added sensors to log intake and charge air to see how this water inter-cooler performs compared to an air/air inter-cooler. R&D fun...........
Tight fit under rear shelf area..mainly transiton from 4" to 3" hose
Intake components: Silicone 5" to 4" 90deg elbow, 4" to 3" reducer to fit 3" hose, Spectre $20 brake duct and K&N Xstream filter. 4" hose would obviously be more air flow but it will require modifying back shelf area some, not ready for that yet.
