From what im seeing my IAT'S2 are the same whether im by-passing the HE or not . From my killer chiller straight to the innercooler, then out to the coolant tanks and degas, or HE, then back to the killer chiller .
deliveryman said his coolant line going to his inner cooler was 53 degrees. i checked the coolant in my degas bottle and another little tank i have and the coolant temp was 59* in degas and 60 in another tank. This is coolant coming out of the inner cooler going in the tanks . my iat's were 122...
With the killer chiller installed on my 2018 roush charged f-150 im basically seeing about 30 degrees less iat'2 temps, than i did without the killer chiller. basically
