some research was done by autospeed a while back on forward facing hood scoops and they actually found that at high speeds, airflow will reverse and flow out of the hoodscoop instead of into it.

basically i am saying that i highly doubt that the airflow into the engine bay will cause enough pressure to actually cause the front end to lift because there really isn't that much air hitting the firewall anyways.

even if there was a significant amount of airflow in there, the low pressure underneath and over the vehicle would cause the higher pressure air in the engine bay to flow down the backside of the engine, around the bellhousing, and out the bottom of the engine bay or out the hood scoop anyways.

in a nutshell, my opinion is that the decrease in downforce is going to be very trivial...at least at the speeds you will be going on the road or drag strip.
