Just want to ask about airflow. Under the hood and above the new grill block is a small slit. Does that allow airflow through the radiator, or that blocked further back? Does the scoop allow airflow into the top of the engine compartment? On my 4Runner, the scoop is blocked inside, which doesn't allow airflow (for anything, let alone cooling). What about underneath the air dam? Does the radiator go down far enough to allow the air that does end up under the car to run through it? Do you have a belly pan to stop that flow?
I'm just wondering if there is any airflow anywhere in the system.
Very nice work!  |
Yes, i am running into airflow issues as the engine temps are now hovering around 195-205F...typically engine temps are 188F.
Yes the sti has FUNCTIONAL
hood scoop that feeds the top mounted intercooler
. The "slit" on the top doesnt lead to anywhere, its blocked from behind. I am thinking of making a small plug for that area too to increase laminar flow. Yes, there is a front FLAT belly pan from Subaru for smoother airflow down there.
However, the issue seems to stem from my larger lower grill block. Back when i was doing my "early" versions of upper and lower grill block, 100% upper grill and 80% lower grill did not effect engine temps at all. Therefore, i am going to trim my lower grill block some more to increase air flow to the radiator.
