For the guys who mentioned the fan/shroud placement issue, can you feel more suction in front of the radiator with the correct placement? One guy mentioned -20 degree difference, did the other poster have a similar result? I have a homemade shroud on mine, and the fans all the way inside it. Looks like taking the spacer off should put it about 1/2" inside the shroud (the fan is 1 1/2" wide).
