But I want to create slightly lower pressure under my suburban. One of the problems with these trucks is cooling. On 2 wheel drives its worse, if you get at bumper level and look under there you have a cross member that catchs about 6 inchs of air and forces it up into the engine bay.
Air cant really go around the bottem of this cross member becaus its got a 1.5 inch lip around the bottem. like an "L" cross section that scoops up the air, so air has to go up into the engine bay.
I want to block the air flow over this massive low hanging cross member and pull more air through the radiator.
And also by cutting away some of the body that covers the radiator, I can gain about an additional 3 inch by 15 inch strip of radiator fins exposed to flowing air, I will have much better cooling.
And yes I know tons of unneeded air flow over the radiator is bad for Cd that is where the active grill shutters come in.
