I understand that I'm just saying a hole up front would help feed air from outside across the top of the engine and out the back side where the cowl is.

Re: Cowl hood the right way

Very nicely done!

FYI:
Though this one appears to be for show and to let some heat out...

The original purpose for cowl hoods was to take advantage of the high pressure area in front of the windshield to stuff air into the air intake.

Re: Cowl hood the right way

What happens at low speed, crawling, the cowl lets hot air out.
But at high speeds, 55mph, the base of the windshield is a high pressure area and outside air will actually be forced into the cowl and underhood. What you need up front is not a ram-scoop but a vent or a backwards scoop because at the front of the hood is a low pressure area and then the hot underhood air will come out there. This same up front vent at low speed will also let out hot underhood air.

That being said, I still want a cowl hood. OP did a great job. I wish I had half of his fab skills.

Re: Cowl hood the right way

You're both correct, sitting at idle you can feel heat being blown out of the cowl. I'm hoping it helps keep the jeep cooler as it gets warm when we start pushing some trails. It just does the opposite going down the highway, the high pressure created by the air ramming into the windshield actually pushes it into the cowl. The other day I was cruising into town and noticed a leaf stuck to the screen until I came to a stop and it blew off.

I'm new to jeeping so it hurts to put dents and scratches in the toy but we've already had it to 3 different ORV parks this year and it's got worked



Sorry I'm not interested in building any. Its pretty time conuming and would cost more than you'd want to pay but now you know how I did it!

Re: Cowl hood the right way

Very Very nice work. It's hard to see in the pictures but did you use metal dowels for the structural pieces? I'm assuming you removed them after you welded in the sides?

Hey Jim the "dowels" are actually 1/4" steel rod I used to form a frame to weld the cowl to. I left it all in there because the hood would be flimsy without the extra support.

Re: Cowl hood the right way

nice work,
what did you do too separate the sheet metal from the supporting structure? when I look at my hood it has a dark glue holding it together.

The glue was weak and released easily for me.
