The air from the turbo is going to be hotter than ambient no matter what, so there is no way it can "reduce heat soak", assuming you're defining heat soaked as 'the state in which the intercooler it hotter than the ambient air temperature'. Besides, the amount of air flowing through the IC from the hood scoop is *far* more than the amount of air flowing from the turbo, even at relatively low speeds.

If you want to fight heat soak, just drive the car > 10 mph, and spray down the I/C when it's stopped to get it near ambient.
