[QUOTE="MalcolmV8, post: 15388114, member: 8854"] Oh yes sorry I thought I explained in the first post. Let me give more details. Very hot day, 98F or so, humid. 2.9 Whipple creates a lot more heat than a stock eaton. After driving around a while and everything's heat soaked and fully heated I'm seeing IAT2 temps of mid 170s to 189 according to data logs. That's just cruising around too, maybe a little gas on the highway on ramps is about it but no WOT driving. Car is running around 205 to 215 or so. Varies with speeds, driving conditions etc. Turn Killer Chiller on and IAT2s came all the way down to mid 120s and saw highs around mid 140s. Of course all that heat gets dumped in front of the radiator so the coolant temps went up into the 230s and eventually cruising down the road with interior a/c on full blast, KC going of course, 244 F. That's when I called it quits, turned off the a/c and limped home and shut it down. Sitting at lights or stopped in traffic yielded the highest temps. Light to moderate cruising on back roads was the coolest, highway cruising was second highest temps. This overly hot day aside, I've noticed in general the cooling system is pretty taxed with the killer chiller running non stop hence decided on a fan upgrade. [/QUOTE]
