      I am using a heat exchanger from frozenboost.com. This might be a mistake, but people see to use them and like them. It is this one:

      It will be mounted to the lower portion of my radiator. There is a port in it where I plan to install a temp sensor to monitor the heat exchanger water temperature. Bosch makes MAP sensors with integrated air temperature sensors. I plan to use one on the cold side of the intercooler core and also one in the hot side of the intercooler core. This way I can not only measure the efficiency of the core but also the pressure drop across the core.

      Tecomotive sells both a crimp it yourself connector kit as well as a pigtail. I got the crimp it yourself connector. There is no controller needed if a Dominator or other Holley EFI system (except Sniper) is used. Here is the relevant PWM information for the CWA150 pump:
