I am getting very high ECT Readings on my 06 AP2. Details on the car are below.

• 2006 Supercharged (14PSI) S2000
• Upgraded Schmuck Built Radiator with custom shrouding and (2) spal slim fans (dual core, twin pass)
• Honda TYP2 coolant, carefully bled and double checked.
• Heat Exchanger, large Oil cooler, AC Condenser then Radiator
• On my 2nd engine due to probably overheating while on the track
• Texas heat (90° Ambient)
• J's racing headers with no heat shield
• Vented Hood

My issue is that I cannot get my coolant temps down enough. Currently they are hovering about 195F on the freeway with no AC. with the AC on bringing in outside air they jump up to 210F and with AC On recirculate they skyrocket to 220F+!! I have checked that the lower hose is warm which usually means the coolant is flowing.

I know i have too much stuff in front of the radiator and the ambient is really hot but is there anything that could do to get things down? I am planning on wrapping the header in an effort to reduce heat soak, but i dont think that will make a huge difference in the ECTs.

Any suggestions?
