While running the engine to check out the systems I noticed that my intake runners become real cold, actually they sweat from the condensation on the outside. I have an intercooler but there was no airflow through it since the prop is not installed yet. I reason that the air is compressed by the turbo -- heated up then had time to cool a bit before getting into the intake manifold where it would expand and cool rapidly and would cool the intake runners. The intake runners were very cold to the touch. The engine was running idle to about 2000 rpm at the time. Rino
