Vented Hoods

[AndyG]

My entire thought,since I'm a contractor, that engine is like an HVAC unit working in a hot attic . I just wondered if I was whacking up my little Tj by doing it .

Those cuts look extremely clean! Been thinking about have the shop do this because my hood has hail damage. I’m afraid my cuts wouldn’t look as good as yours and that would drive me nuts.

I like a turbo diesel . Because diesels are sluggish.

I've always been a 258 then 4.0 fan .

What gearing with 33" works best , that may be where I'm off .I'm 4:10 .

You can do it, all you need is a 1 inch hole saw and a 4.5 inch grinder with an abrasive blade. , and a little spray paint. Its easy.

Thank you sir. I try to do things the right way. A good file will clean up the burs off the edge nice. It may be like cheating , I have been a custom knifemaker for 24 years now and that helps to have the right tools on hand. I have been in meta fabrication for 35 years now.

My wife , the self proclaimed Jeep stylist of the family , is shooting down the hood mod , man those look good.

My hood had i think its heat damage.It had small cracks in the paint mostly in the middle of the hood where its covered now. So it was gonna need painting if i didnt cut it out.

I installed day star hood latches, my hood never once fluttered. They were a great piece. My louvres didn't change anything about it either. I need to swap the louvres over to my new chopped hood still...

I can tell by feeling mine that heat needs to get out ..belts , hoses , wires ..no good comes from that kind of heat build up.

Thats right , heat is ok, but too much can cause other problems. As Chris says , it is designed to run a certain temp, but too hot is not good for other items

If you do a lot of highway driving , 4.56 is probably the best gear set for your specific situation. If you don't do a lot of highway driving in the Jeep, I wouldn't be afraid to go as low as 4.88 or maybe even 5.13 if you really don't care about the highway. Gears will make a huge difference. I would worry about gearing before I worried about adding power to the 4.0L.

That's the one I was thinking of ,poison Spyder maybe?

Good looking Jeep.

Installed myself...Easy enough and I believe it does help take out some of the heat issues.

So if I go up and gearing it's going to make it pull better?

Like putting a larger sprocket on the back of a motorcycle?

Yes that's a good analogy. Exact same principle.
Speaking of louvres I stumbled across these on eBay a couple months ago..

These louvres are used, from a 98 Grand Cherokee. It was an impulse buy from eBay.
I bought them for looks primarily but also for heat relief during the brutal Texas summers

Yes. I put 4.56 gears in my TJ, with the 4.0 and 5 speed and 33s. What a difference! Like I had more power.

 

[AndyG]

Awesome , I'm checking into gearing now

Love those louvres

So here is what I did. I wanted something not so massive, the one that looks covered on the passenger side was covered with a sealant to provide a little protection for the battery. other than that these were purely cosmetic.
