At around 30psi on a GT3040 I was getting 120-125degF temp drop but around 3psi of pressure drop, and 125degF intake temps (measured using type K thermocouples on a cool day with 85degF water temps).
I replaced the Frozenboost I/C with a custom A/W IC with a Bell core (6" x 5.3" x 12"), and on a 90 degree day in Memphis with about 25psi of boost and saw over 200 degF temperature drops and 140degF intake temps even with 126degF water temps. Unfortunately my pressure sensors have not been working so I haven't been able to log pressure drops yet.
Just some data points, but the larger Bell core cools SIGNIFICANTLY better than the Frozenboost cooler did.
