Jeep Wrangler aerodynamics - yea I know

[44Dan]

Air flow ribbons tied to the vents showed positive air flow out from engine bay at various speeds including highway speeds. My fault not mentioning that earlier. We were not worried or thought about negative pressure build up but rather wanted to see how well the air flowed (one guy did anyway) so we tied small ribbon strips to the vent openings and the engine bay pressure was extreme from where we put our vents which were more central located on the hood. Wish I could find an old photo but I can't find one. We see a lot of Jeeps with this less than $5 mod in Arizona, especially the hotter areas.

Hope This Helps
