With constant 95-100f and high humidity I am lately seeing consists. 216f with AC off and 235f with AC on.

I am concerned since I feel like oversized heat exchanger for 10psi SC application really limited the flow to my radiator that much more.

Should I be concerned? Even at 80mph at 70-80f outside temp I hardly see 190f and more like 205f consistently.

 

216 is high but not too bad although 235 is something to be concerned about. Where are you getting these readings? Maybe it is time for an upgraded radiator and fan assembly.

 

, I am using ScanGauge II to track my AIT and WaterTemps.

 

What are you using for engine management?

 

Emanage ultimate

 

Are your fans operating properly?

 

had same problem same setup. does it go down at speed or stay the same? I ask because after I put the large after cooler in and fullblown radiator and a spoon thermostat the car ran cooler but if I got stuck in traffic the thing would heat soak and just stay there bought a vis mg vented hood used and I went from 218 in traffic to 205 and after 3-4 minutes rolling it would go down to 185 with the ac on and more power and down force even put a 170 thermostat back in as the car ran cool in the fall and winter. only other thing is to trim the bumper to let some air around the after cooler or tilt it my iat went from 160 heat soaked to 145 and I run meth that made a huge difference in the temps also I put an oil cooler on it that helped on several fronts coolant temp and oil consumption I believe these motors run too hot on oil temp and it gets cooked of like oil on the stove I left the stock cooler in place and put a sandwich on top hope this helps an I was running emu. running aem on there now but nothing wrong with emu good luck

 

I had the same heat issue last weekend in the desert. I ordered a new Mishimoto kit with 2 @ 12", fan shroud and temp gauge to kick on fans 15˚ sooner.
All on order and due end of this month. Next issue is the OE hoses. With SOS kit you have to re-route the upper hose NOW any silicone hose kit will not fit.
Emailed SOS but NO reply. "Venair" make a S2000 for OE but not sos kit applicable. sent SOS the link to that kit. maybe it could be made??

This very thing has stopped me from installing the SOS upgraded heat exchanger . 235 is HOT . I would be very concerned . You can try and angle the radiator back slightly to see if it helps . I would much rather have higher iat's than high ect's .

 

Everything functioning properly, today was 70-80f humid day and I was at 205 pretty much. At 206 fans kick in and we are down to 200. From there on at 75mph cruise I was a steady steady 201f.

Hmmm
