Cant believe its taken me this long to read this thread. For some reason i keep forgetting there is a 6.5 performance section. I picked up a WH1C (A predecessor to the HX-35, just held together with a band clamp instead of bolts), and a 1997 Dodge Ram Cummins intercooler. I just got done reading Turbine Docs thread on my lunch break about not needing one, my truck does tow sometimes, and when it does its a load. My A/C does not work and im prolly going to get rid of it all in order to install the intercooler infront of the radiator. I currently have a Kennedy high output fan clutch and D-max fan blade, plus i re-calibrated the clutch for even more cooling (i still kept reaching over 200 degrees F with the fan and clutch) I am slowly in the process of gathering parts to do this swap next spring. I also have 1 HO older Taurus fan, and an extra motor for it! So id only need one more. Do you think these two electronic fans will pull enough as to keep me cool with the plow on? Im worried that the I/C will be so tight infront of the radiator i might have to push it back a touch? Also on the 4'' D/P, i would love to do that on my truck, but i have ZERO welding skills, non-the-less a welder. How much difference you think that makes over the 3''? I cant wait to do this, id also have to fab up the wastegate with a spring.
