Hard top on doors off
 
Is there any kind of wind tunnel effect when you take the doors off but keep the hard top on with the back window. Didn't know if it would create some weird resistance.

I have the hard top and use half doors and take away the windows and also have a custom back window made out of plastic .when i close the windows the back window goes flying and making noise when i open the doors windows (take them off) it makes the back window stay in place and dont move. Give it a go without doors i will probably work have fun"

Should be fine...but why the half measures? Why tempt fate? Go all the way, man. Hard top? Please. Top off, doors off...otherwise, why buy a Wrangler?

Not by design. Garage is full of tons of stuff plus my wife's jeep. I can squeeze the doors in there but not the top.

Aero engineer weighing in here.

"Wind tunnel" is not the correct term but yes there will be problems if you take the doors off but leave the hardtop on.

You'll notice in other vehicles, with a sunroof, that they have a small spoiler that juts up when the top opens. It's because you need to force the air to become turbulent (e.g., stirred up) before it enters the open space in the vehicle. Sometimes, I'll pull the spoiler down just for kicks and all of a sudden in our SUV there is a pulsing to the wind inside, making a low thump, and the kids complain.

It happens because there is nowhere for the air to escape out the back if the air was not turbulent when it entered. So the air rushes in, overpressurizes the space, pushes out the opening, and then rushes in again. It cycles every second or so, and this will vary depending on the vehicle.

If there was a small open window at the back this would not happen.

It's the overpressurization that causes the rear window to fly open.

Not much you can do about it except poke a hole in the rear or remove the rear window.

Better yet, get the longer bikini top and enjoy fresh air from all sides except above.

I've been going doors off/top on lately as well for the same reason. Don't have any place to store the hard top. It's fine as long as it's not too windy. On windy days I get blasted in the face with wind that almost feels like it's going to rip my glasses off my face. That might just be a Missouri/Midwest thing though. The wind here ****ing sucks sometimes.

SELL the hard top! There is no need for a hard top in the south... :whistling:

Sucker Punch 06-22-2013 12:43 PM

Also the hard top is a pain in the rear to get off/store and that is why you always see people driving around with the hard top on perfectly nice days. I doubt some people ever take their hardtop off :rolleyes:. Hardtops are too inconvenient for me and I would only use it 2 to 3 months of the year where I live. If I lived in Gulf Shores I'm not sure if I would ever use any top period... But that is just me and my measly 2 cents. Not dogging ya, but I think a soft top would suit your needs better if you have no place to store a bulky hard top...

I hear ya. The wife has a soft top and part of the negotiating a second Jeep was to have a hard top. So that's what I have and it's fine. When we get a larger garage I'll install a hoist and this situation will be a thing of the past. Thanks for the replies to all.

You ain't getting off that easily.

1. Got an extra room? Cribs only take up so much space. And a hardtop could actually save a life. Think about it...

2. Dinner table too small? Damn. A hardtop, couple of sawhorses, you're golden. After the apocalyptic storm, Hannah would say, "Thank you daddy." No, princess, thank the sawhorses.

3. Have I mentioned Midwest storms...Oh. Hmmm.

4. Negotiating? Larger garage? Jesus, take control of your life, man. No doubt Your wife would allow you to spend profligate amounts of $$ for your Jeep, in order to make it the most badass road cruiser in the lower 48. Otherwise, you wouldn't have married her.

Right?

I rent and have no place to store my hard top either. I've been looking at how feasible to take the back window out. From what I can see every thing should come off really easy, and it's 4 screws into the hard top to remote the hinges. But the wether here has sucked for the last month and haven't had the doors off in weeks:'(

I run mine like that, it isnt too bad. Biggest issue is seat belt flap, the front belts flap and slap against u like crazy anywhere over about 40. Anybody have any ideas to stop this? Otherwise I like the doors off and hard top on, personally I think its looks awesome

Go to Walmart and grab the black wooly seat belt pads that will stop that flap and if you get the black you won't even see them

HunterTheBeagle 06-22-2013 07:57 PM

Ha, if I would have looked a few posts down I would have solved my problem. :facepalm: http://www.wranglerforum.com/f33/qui...er-251073.html

This is what I'm talking about, works for the rear belts too

I run it that way. No wind or pressure problems so far. I wouldn't sweat it.

Main reason I run it it that way is the effort required to take the top off. Eventually I'll get a hoist. I can take the doors off by myself in 5 mins. Also the hardtop keeps the sun off.

For flapping of the seatbelts - Amazon.com: Bell 22-1-33237-8 Grey Memory Foam Seat Belt Pad: Automotive for $10. Wrap them around the belt between seat and b pillar. Flapping stops.

Those Fuels are nice. Debated on those but went with the Octane's.

HunterTheBeagle 06-22-2013 09:33 PM

Thanks! I will have to grab some of those.

CaptnGus 06-22-2013 10:36 PM

I've had the doors and front roof panels off, leaving the back part of the roof in place. I had no problems. But, I wasn't driving at highway speeds.

Same here, drove it with no front doors and panels removed and didn't notice anything more than extra wind. Have to keep the back doors on for the kids but they didn't complain about noise or excessive wind.

Thanks! It was a tough decision. I bought a set of XD Addicts and hated the plastic lugs. Sent those back and got these. They're a bit "louder" than I wanted with the machined accents but they are growing on me and I get tons of comments on them. They have an aggressive look.

I started with just a hardtop. (Added a soft-top this spring and loving it) I ran with freedom panels off doors off several times last summer/fall. Never had any issues even at highway speeds except that the wind noise is louder and the wind itself seems to be a little crazier in the cabin. It's definitely better to run no top, but I preferred that arrangement to having to keep her all buttoned up, when getting the hardtop off wasn't an option.

FYI only time I have experienced an over pressure cabin was with doors on, windows up freedom panels off. But even just cracking the rear door windows would solve it. IMHO it'd be great to have an option of choosing a hardtop with a no rear wiper, removable rear window. Would make the freedom panels even better.
