I think maybe if a performance thermostat let you block off the grille openings. You would want the minimum size opening to provide sufficient airflow to the intercooler and radiator. Anything else could be taped off to provide better aero.

It would be slighlty cooler, the above should raise the coolant temp slightly but it should be regulated by the thermostat overall. This "performance" would have a larger opening to let coolant flow through it with less resistance. The idea is to maximize the efficiency of the coolant system, in other words, let coolant absorb heat from the engine where it's needed and let coolant flow more efficiently where it's needed. Unforunately, I'm pretty sure that the engineers who made the block have already done this study with 1000x better results and knowledge that anyone short of an engineering house could achieve...so all you could do is clean up casting flaws or rough edges. Maybe a larger radiator could also help.

Kind of, the overall idea is to improve the aerodynamics of the car by blocking off most of the front grille. Adjusting the cooling system is just to keep the car at a reasonable temperature. The thermostat only controls the flow of coolant to the radiator and helps control the temp of the coolant.
