[QUOTE="tt335ci03cobra, post: 15785286, member: 68944"] Supercharged engine, regardless of coolers, are temperature slaves. A zl1 1le might stay cool in fall Germany for 2-3 Nurburgring laps, but up the ambient temp 50° and it’s gonna heat up very quickly. My turbo cobra has a hard time getting to temp in the fall and winter, high boost and all. 10+ pulls and I’ll still be seeing 50-80° iats. Mid summer, 10 pulls will put it into 120+°. No wizards work at play, and I have a fully jet hot coated hotside, exhaust (to and including the tail pipes) diff, oil, brake and (soon) trans coolers as well as a large inter cooler, and aluminum radiator, Lincoln mk8 fan (5000cfm), etc etc. I had cooler oil/water and iat temps after a spirited summer canyon cruise than a bolt on sti and a magnusen supercharged gen 5 Campari and and I found that very funny because they weren’t driving very hard and I was flat footing 800whp on most of the open straights. That said I still pushed 230° coolant temps and 130° iat’s at the hottest. My point is regardless of how well done, a boosted car won’t stay cool if driven hard in heat. My buddies gt350 tech car gets up to 240-250 coolant temp though so but he’s building it up with a supercharger for mainly straight line work. That goes to show that even na cars obviously benefit from real cooling system thought and setup. He built my cooling system for my turbo car and it surpasses his gt350’s stock setup in an na setup. The gm techs talking about 11 coolers are including the radiator etc, the compressed inter cooler between the blower/valley, etc. By their counting an 03 cobra had 3-4 coolers. Most cars have 2-3. Don’t buy too much into the hype, once the coolant is moving around and the fins get hot, physics are physics, the zl1 1le will fall victim to heat sink, just later on.
