So fundamentally, it follows as I would suspect.
Centrif/Air to air can not possibly remove heat as quickly from the charge air because air is not a great heat transfer media. 109 is very respectable and only about 30 deg over ambient at the end of the pass. This indicates an adequately sized air to air intercooler. Iat2 starts at 77 and ends at 109.
PD/Water to air can extract more heat from the air charge but the water can heat up and limit the effectiveness. Iat2 might start out warmer due to warm water, but won’t increase much over the course of a pass (unless the unit is undersized). Iat2 might start at 100 due to warm water but only rise to 110 over a pass.
