yup,this one helps
remove the rubber strip in between the hood and windshield so the heat can exit better as well.
According to scientific testing in the hood cowl rubber stripping thread removing the seal will decrease airflow and the GNX Style Oliver’s do little.
. im talking about letting the heat escape,put a temp gun on it and its easy to see.i havent used the airflow meter on it to check flow but i cant see how trapping it would help,lots of guys run with no hood up here and i know thats worth alot in temps.as fatr as the gnx vents i havent played around with them.
When the car isn"t moving hot air will escape from the cowl opening without the weatherstrip in place but when you start going 30 or more the air is actually sucked into the cowl opening thereby decreasing the air coming in from the front of the car. You can prove this by taping some yarn onto the back of the hood and see what happens at speed. That is why cowl induction intakes do in fact work. I used to remove the weatherstrip in the summer thinking it would lower under hood temperatures but in fact was flowing less air thru the radiator and running higher engine temperatures.
i did not record higher engine temps in the past with the weatherstripping removed, i will put a temp gun on it later today at higher speeds and get back,if i see a real drop maybe i will put the airspeed meters on for a more accurate test.
Let us know what you find. Do tape 3 pieces of yarn onto the hood at the center & split the difference between the center & ends by the windshield and see where the yarn goes at 30 to 60 MPH.
