Well, a couple of incarnations of the hood later, I've found a combination of vents, and flappers that does the job of allowing the airflow to vent, and not flow back into the engine bay.
The result is a steady 200 degree temp at 70 MPH on the highway, with a few high speed runs showing no significant increase. I still plan on putting vent flaps in the radiator shroud, but it's not a critical mod at this time. I'm happy with the results. The looks...meh
I bet you can surprise some people.Yes, they were functional, & those things were pretty fast for a 4200 pound vehicle. I checked on those vents, and the damn things are about 400 bucks new, and there's none in the salvage yard. :-(
The 1998 Grand Cherokee 5.9 limited had a cool looking vent on the hood. Not sure if it was functional or not.
Great work.

Now THAT'S a bumper/winch combo! It also balances out the look of the "snorting nostrils". IT'S A BAD BUGGY!Yeah, I noticed the vents didn't seem to stand out as much! I'm pretty happy about that. Glad I'm not the only one that sees it. Thanks, Man!
Nice! Glad you got it "done" (haha). I wish I could get out west to go wheeling. Beautiful scenery! I'm on the east coast and try to stay in the rocks when possible. We're mostly dense wooded trails and of course the EVIL mud. In the GW National Forest (nearest legal place to me) any mud you find is mostly decayed oily shale that turns into a yellowish muck that stains everything. Super slippery too. I had to service my transfer case linkage yesterday as it would no longer get into 4-Lo. I need to get 4 new bumpers for the linkage where it bolts holder to the body. At least I'll be good for OBX this coming weekend. Here's some of mine recently...
Just thought I'd post back. I got the OEM grommet kit, cleaned everything up (wire brush and straighten) and kept it stock. Works great again, nice and smooth. Took it out last weekend for a club ride and everything worked perfectly.Good deal on the 8.8 axle. They are plenty stout. They do have some issues with the tubes twisting in the center section, and a lot of folks get them welded before installing them. I've never actually seen it happen. I'll probably get one for mine, if the CryCorp axle ever grenades. So far, it's not showing any signs of doing so, after 11K miles.
On a side note, I just picked up a polished Banks SS header to replace my cracked OEM cast exhaust manifold. Also, my Ford 8.8 4.56 rear axle is ready to go in, and I have all of the parts to swap the front gears out to 4.56. Now if I can just find the time.....
