Yea I know.

I have a Jeep Wrangler that does get driven off road somewhat. Most of the driving is on road. To aid with slow speed cooling I was thinking about adding a set of hood louvers to allow hot air to exit the engine bay. I have a the option of putting louvers on the side of the hood also.

I know there is an eddy that sits in front of the windshield.

I was wondering how will "injecting" air into this eddy affect dthe flow around the windshield/roof area. Do you think it will increase or decrease drag?

Thanks
Don
