Heat soak really affects car when hammering on it... Daily driving just doesn't "generally cause an issue just cruising, unless you jump on it for some reason. Then the heat load can lead to detonation, which causes the knock retard sensors to start pulling timing, which reduces power.. but can save a motor...
I don't recall ever seeing anyone with forced induction pulling into a drag strip, teching a car and heading straight to the staging lanes... They go to a parking spot, pop the hood and let the furnace cool down for a while...
In racing conditions, this can occur quite quickly. Most say that forced induction motors are no good for road course type racing, and I agree for the most part... due to heat soak... the power can go away quite quickly...
Low to moderate boost cars can sustain the power longer, but naturally aspirated motors can be built to the same power levels without concern for heat soak power loss...and are much easier to tune to deliver consistent power throughout the course of a track day..
