I think if the scoop had been reversed and the underbonnet heat was to exit the rear towards the windscreen, the underbonnet air flow may be greater due to the negative pressure felt at the mouth of the scoop by venturi effect and maybe it would help to pull in more air through the multi layers of radiators where its needed most...just a thought...
@turtlezed and bad. Closer to the windshield the air pressure on surface steeply rises as the air gets condensed on edge of hood. So it would in fact press more air under hood, maybe even better the it actualy does with this position of scoop.
But you have to measure pressure over and under hood to see the pressure map and decide best way how to do it.
What is really wrong about this is increased lift force, as the air will obviously have to evacuate engine bay thru bottom. I won't be happy here
ok but you should have added a row of tape on the hood in front of the scoop. you would then see the string rise up off the hood and into the scoop or over the top
@xenomann442 if you want to get hot air out of the engine bay and drop under-bonnet temps, then yes, it is worth it! If you want to turn heads with your hyundai excel, then no...
I realize it's obvious. Some people thought air that came through the radiator would create positive in the engine bay and exit the hood scoop. This was to prove my point.
works for me!

Good idea Mike. I may try that when I have a chance.

is a hood scoop even worth it? does that extra air intake balance out the wind resistance? Cause i would think the aerodynamics are more important

@xenomann442 Anytime you have forced air, it is a Positive thing.

so if the scoop reflected the air comes out
