[nubbzcummins]

I have a little dilema.....I drive a 2006 Dodge Ram 2500 with the cummins turbo diesel. My most current mod was that I blocked the grill approx 90%. What I have noticed by doing this is that the water temp now runs in the 190-200 degree range which is up approx 10 degrees and the intercooler is much hotter than before. Much hotter as in the outlet of the intercooler is almost too hot to touch after just cruising at 3-4psi vs before when you could barely feel the temp difference between ambient and outlet under the same conditions. My question is the much hotter air going in my motor hurting me more than my grill block off is helping? I am getting better mileage but I have been doing a lot of "N" coasting during my daily driving in the order of around 20% of the trip. Any help and/or tips appreciated.
