Hood-Windshield Transition

any ideas on how i can improve air flow transition from the hood to the windshield on my Jeep? i'm looking for something relatively simple to do, and that doesn't look like a giant cowl induction hood scoop

...a clear "bug-deflector" that goes from the front of the hood right up to the top of the windshield?

...maybe not!

decreased hood to windshield angle is on the 65+ mods list. i have no intention of chopping the top of my Jeep, so i'm looking for something that could possibly give similar results without a ton of fabrication

By golly it is on there... I don't think it should be

The Geo example given... is a good example of frontal area reduction and also better aero on the rear of the vehicle. I don't see a shred of evidence that the hood/windshield angle did anything good.

Look up aerohead's posts (he could very well be our best resident aero authority), in about 1/4 of them he states and restates that it is the rear end of the vehicle that benefits the most from aeromods.

yeah i've looked through his stuff quite a bit (hence the statement of "doesn't look like a giant cowl induction hood scoop", like on his pickup (not knocking him, i have no doubt it works, just saying i need something simpler)) but not sure of what i could really do on the backside of my Jeep

But He has also stated if you don't clean up the front, the back will not do much good. It is a total package, and I have seen multiple people suggest starting at the front and working your way back to realize the most benefit.

I'm going on a roadtrip this summer to California which will require me to put a hitch basket on the back for carrying extra gear. maybe i can design it into a sort of hitch mounted semi-boat tail??
