I also believe there is some air trapped at a low point in the plumbing and is restricting proper flow. With proper coolant flow, I don't believe it is possible to generate 200+ degree IAT's during a few seconds run even at 90*+ AAT.

thats what i used to believe until i did all possible mods to control heat,, my next guess/mods,, hx tank,, 14 rib rear,, sc oil change,,

i live in saudi and its 90+ all over the year,,

With the 1 gal LPE coolant reservoir ( if available for the CTS-V) the air will migrate to the tank if you've got good enough flow, plus you can open the cap and watch for good flow. Trapped air that aerates the coolant is also less likely to get sucked right back in, since the reservoir gives it a chance to settle out and accumulate in the tank... being visible now.

another vendor sells an ss tank for v but its out of stock i guess,, i might fabricate one locally,,

Maybe also verify the inlet/outlet of the heat exchanger are not reversed.... which could allow air to be trapped easier?

i know this sounds unreasonable but i am coming to a conclusion that my issue is not related to sc cooling cycle,, i have tried more than 5 combinations of hx and pumps,, 3 hx and 2 pumps,, iat2 read the exact same numbers and behaviour with any possible combo,, i doubt the sensor this time,,

i even tried that in purpose,, nothing changed,,

I believe it is not reasonable or probable that 5 different combinations of 3 different heat exchangers and two different pumps could in reality produce the exact same numbers. There should be some differences, even if it's only 10 or 20 degrees. If you have a logger, with a completely cold engine, turn the key on without starting the engine and log the ECT and IAT temps. They should be very close to being the same.

i wish am wrong too,, i just got in from garage,, pulled the bumper and hx off,, twisted the hell of hx just to make sure no air in there,, tested the pump,, all work great,,

one new thing i did,, i bent a small steel plate was securing iat2 sensor from popping out,, i bent it away from sensor desperately wishing it was heat soaking,,

fluidyne lower hx,, w4m lower hx,, stock hx,, zl1 pump and stock pump,, all possible combinations,, i even tried running two hx in series,, same results,,

Good idea for checking the integrity of the sensors. Something's fishy.

If you're not running a catch can, possibly you're getting oil in the intake and the innercooler has gotten clogged a bit or coated with baked on grease. I've never seen it 1st hand... just pictures.

Verify the sensor accuracy 1st.

i run dual catch can mainly for this reason,,

for iat accuracy,, i will think loudly,,
iat sensor included with tvs2300 is meant to be sliced in maf/iat wires,, in my case it was sliced in factory secondary iat (iat2) which was used originally to measure post charge air temp,,

using hptuners editor,, i found that iat2 has a different resistance/temp map which is 36*f higher than iat in most cases,, i will try to remap iat2 sensor,, i wish this will make any sense,,
