Installation - Charge
Water to air Intercooler
First mount the Renn27 intercooler core to the throttle body and charge pipe. The location of the intercooler should be tested and adjusted so as to clear everything around it.
Next mount the provided mounting bracket to the intercooler to ensure alignment to the Porsche engine bracket. The bracket needs to have a hole drilled in the as shown below.
The 90 degree black silicone elbow connecting the turbo to the charge pipe may need to be trimmed to fit properly.
Charge water reservoir
The aluminum reservoir for the WAIC is bolted to the chassis as shown in the photo gallery. Its position is dictated by the hoses that connect it to the intercooler core.
Once you have the intercooler fully mounted and lines connected, you will want to drill 2 holes and install rivnuts into the sheet metal of the car to mount the reservoir.
Charge water pump
The pump for the WAIC system is mounted to the lower bracket for the heat exchanger with a cushion clamp. Power is provided for the pump via one of the left over connectors for the Porsche rear o2 sensors near the rear lid hatch. They have switched power to them when the engine is running and a few minutes after the engine is shut off.
The heat exchanger's location is suitable for street use, if your vehicle will be used for extended hard driving on track, you may want to add an electric fan to provide more airflow to the heat exchanger.
It is also required to smoke test/pressure test the intake and charge pipes at some point before requesting Renn27 tuning as this is essential to proper air/fuel specifications.
