Well, After doing the installl and coolant piping. I managed to get the truck to an AC shop. A few glitches, but we ironed them out. (make sure they use the correct O rings!!) Anyways, Got a chance to test out the unit. 1 word Awsome. At 80 mph cruise, I go WOT and IAT2's are 102 deg, IAT1's were 128. keep in mind that is spinning a STOCk eaton with a 10# lower. In traffic is slightly higher, but so are the iat 1's. I currently dont have a real CAI, just a temporary K7N filter sitting out in the open under the hood. Nice thing is, there's no feeling of power drop off on a WOT burst from, low to high speed. went from 40 to 120 and the power was smooth and constant. The heat wash to the radiator was about 10 deg, but i am running a electric ewater pumop, so im not sure how accurate that would be on a mechanical pump truck. I unhooked the tranny line from the radiator and am running it back to a B & M race cooler with its own 9.5" fan, so nexty time out ill do some more reading. BTW, i got these temps with the aeroforce OBD2 gauge.:beer:
