Well thats what I'm doing. Just for fun really... I picked up a Nordskog Temp gauge that reads as low as 60 degrees Farenheit. I'm gonna install one tomorrow in line with the coolant piping going into the Intercooler. Later I'm gonna have one monitoring the coolant coming out, too. That way I can get an Idea of how efficient the 165 intercooler is. Any comments? Anybody do this before?
