I'm all for lowering underhood temps, but I'm not sure tha's going to work as planned. I would expect it to have some positive effect when stopped, just not at speed.
Right now the next items I've got to do for heat management is venting the fender liners, putting in a slightly lower temp thermostat, and going to a different mix of antifreeze and water. A vented hood may happen down the line, but I'm not sold on that on a daily driver.

Well you might get a good report here soon...if something happens for me.
On the hood seals, it would depend on the air pressure under the hood. Like the GT500 this is true, that is why they vent from the front because air pressure is pushed forward to that point and is released from there. The Z might push air backwards possibly or down even while driving which means the best venting is the vented hoods and under the car.
Need someone to run some pressure tests on a stock hood and determine airflow during idle, slow driving, WOT, etc.
