New Ideas for The Eco-Wall
Okay, so normally I would ask for some suggestions on how to help improve my aero, but I've decided to do it differently. I'm gonna ask you what YOU'D do to it and I'll collect my ideas from there on.
So you have my vehicle, A 1995 Jeep Grand Cherokee (ZJ) with a stock Cd of .44, and you want to do some DIY stuff that you can easily take off and make the vehicle back to stock whenever you want to. It's 2wd, and, has some weight in the back that you cannot remove (my audio equipment). Not much done, just removed roof racks, inflated tires up to max(actually a lil over), and a few more things (everything listed in EM Garage). What would you do? |
I was real close to buying a red Jeep GC like yours 1.5 years ago instead of the Geo, so I can totally relate with you mean when you say you want to keep your Jeep and get good FE too.
If I bought that Jeep instead of the Geo and found this website somehow I'd: - add a grille block from inside the engine bay - somehow lower the Jeep a few inches (since lowering a vehicle has a significant improvement in Cd.) And yeah, that's about it since you already got rid of the roof rack and upped the psi. *Jealous of Jeep* When are you going to start your gaslog?? |
You got some great ideas in your garage. I agree with Peakster. Grill block, and a front belly pan right away and work on the rest of the undertray later. If you can drive without it a mirror delete or at least on the passenger side and some kind of rear wheel skirts. Might also consider a higer temp t-stat. Did you get the vacuum gage? If not I would put one in.

I think we need to see some gas logs so we can gauge any improvements on the mods that you make.

A few thoughts:
1) I'm with popimp: recording your fuel consumption has to be the very first step. 2) next most important step: install efficiency instrumentation of some kind to hone your driving technique. 3) I'd also consider a block heater or 120v interior space heater, so you can stop idling the Jeep to warm it up. 4) Look at the latest crop of GM SUV's: they all have significant air dams below the front bumpers. You could make a removable one so you can still have your approach angle for playing in the mud. |
Oh and ...
5) A muzzle for your brother so he can't bug you about your efficient driving techniques. :p |
The whole removable part is so tricky :p
On the far extreme side of things.... Get a new tailgate and install a boat tail to that (on top of air dam and such). When you want to switch back - change back to the stock (unmodified) tailgate :) |
Could also build a semi-boat tail on a strap-mounted bike rack. (Or just use the bike rack attachment method for ideas to make your own approach).

I've had a Flea-sized hatchback rack hanging on a hook in the garage for a couple of years. But I'm betting - by the pace my own mods get done - someone else is going to do it first :)

Soon I'll get a pic of what the grille block looks like, this I guess you could say is a "before" pic V http://a877.ac-images.myspacecdn.com...b1d00d45f4.jpg Quote:

Tomorrow I'm changing the oil because I'm a little over do and I've got the oil, It's Mobil 1 5w-30 Truck and SUV Full Syn motor oil. I also got a can of sea foam to try and help get out whatever gunk and sludge, water or whatev that has built up in the crank case and cylinders, and valves. I've used Sea foam before in my fuel and unlike everything else it seems to really work. swiped those injectors clean. Last oil I used was Mobil 1 High Mileage 10w-30 Full Syn motor oil and helped oil burn off quite good. Previous owners didn't know squat about maintaining a vehicle. I bought the thing with no oil on the dipstick, had 7500 miles since the last oil change, really low coolant, failing t-stat, really low refrigerant level, Spark plugs with almost no electrode with a gap double of what it's supposed to be. A fuel filter so clogged the fuel went in clear and came out black. a leaking differential, tranny fluid that hadn't been changed in centuries, and lots of other things I don't wanna bore you with. |

You can ask at a Jeep dealer. I wouldn't be surprised if they can get them. I'm pretty sure jcwhitney.com sells 'em, or buy from a real parts store. I wouldn't expect the "big box" parts stores to stock them but traditional parts stores, yes. In my area we have NAPA, CarQuest, BumperToBumper - those guys. The good block heaters are the ones that install into a freeze plug opening. Heater replaces the freeze plug. Reason is, that lets the heater warm up the main body of coolant in the block. The heat disperses well into the block to warm it throughout. I think that's the type that's most common up in northern US and Canada where lots of people have block heaters. Another type installs into the heater hose. It needs some circulation to carry the heat to the engine. Probably easier to install but a more complex design and concept. If there's no pump in the heater unit then it's relying on convection to carry the heat to the block - not the best way. Least successful are the ones that heat the oil. Some by a heater pad glued to the oil pan, some by a heater built into a substitute dipstick. Aside from problems when you drive away with a 120V cord in your dipstick, these don't really heat the block, just the oil, so they can't accomplish as much preheating as the ones that heat the engine coolant. |

Yea I agree that 7500 miles is really not that big a deal. In Europe they go lots farther then the marketing kings here at 3000 miles. No oil on the stick that not great.:eek:
On the front belly tray just attach it to the lower part of the front grill and go back to the end of the engine bay. There's lots of choices to use. I think cloroplast is the favorite. It's the stuff campaign signs are made of. A vacuum gauge can be bought at any auto parts store and probably at wal mart. Search the web you'll find all kinds of stuff. |

You guys probably don't know what conditions I drive in. But it's not pretty. I live in a place not even big enough to be called a town so it's actually a village. Only the in town stuff is paved and it's paved by laying down tar, rocks, tar, then rocks again. The rest of the roads are gravel/dirt/mud roads. Everything is dusty and full of chemicals from the power plant and whatever the farmers decide to use nowadays. My whole engine bay is light brown and muddy now. It's not regular conditions and it definitely files under the "change every 3000 miles or so" maintenance schedule. And looking at who maintained the Jeep before me.. really didn't maintain it at all. Fuel isn't supposed to be black when it comes OUT of the fuel filter, and spark plugs aren't supposed to look like they just went into a volcano and back. If I had the vehicle the whole time. I'd probably go with longer intervals, but the vehicle is a little rough right now and needs to be maintained at the best right now. Oil change went well tho, I was kinda surprised and not surprised of what came out of there. Runs easier now, especially since it's cold. Quote:
Cloroplast.. isn't that something in plants? :D That should be in hobby stores or something right? in any event I could get something temporary for the moment. |

If you have a sign shop around you could probably get the coroplast from them. |
I've found a vacuum gauge that isn't all that much cash, but I think I'll need a tubing kit. Sunpro makes a tubing kit, it should work with the tubing kit right? unless they design their stuff differently. Does anyone know if they will go together?
EDIT: WOW I'm blind, I looked back at a post about a vacuum gauge and Lazarus posted the exact link to what I was looking for above. I'm blind, :rolleyes: |
Don't the Jeep Grand Cherokees come with an instant fuel economy meter mounted on the interior roof, just above the rearview mirror? The ones I've test drove did and even the Quadra-Trac Laredo with the inline 4.0L I drove was reading 30 mpg(imp) at 55-mph.

No, That was an option. I didn't have one when I bought it, that was an overhead console option that apparently was not picked, along with 4wd (who buys a Jeep and DOESN'T get the 4wd? Only people who go and get groceries with it that's who.)
http://memimage.cardomain.net/member...78_19_full.jpg Here's a pic of the day, or the day after I first bought it. As you can see, there is no overhead console (or subwoofers). If only they had bought it with the instrumentation *sigh*. |
I've found some block heaters, but I can't quite find out what size I need. It's an AMC I6 engine, so if that helps any..
|
Your best bet would be to call a Jeep Dealer and get the part #. The use the part # to search online.
|
I'll do that :thumbup:

Ok, so I got pics of the grille block, removed roof racks, and I recently washed the Jeep! Well, here's some pics
Grille block after about a week, kinda weather worn, it's been through about a week and in the rain but it's still on there. http://a163.ac-images.myspacecdn.com...dc01e819c2.jpg Upper grill, slight block, and I tried to smooth the air by using duct tape on the license plate holder/cover on the brick wall bumper. http://a613.ac-images.myspacecdn.com...ddd57e752c.jpg Roof rack Delete http://a962.ac-images.myspacecdn.com...0311fdd379.jpg Another shot http://a25.ac-images.myspacecdn.com/...453c931608.jpg Before the wash, i rinsed off the caked stuff the week before http://a91.ac-images.myspacecdn.com/...dd0d2dd392.jpg After http://a244.ac-images.myspacecdn.com...91dacb6a8b.jpg Another http://a661.ac-images.myspacecdn.com...2429f4b36c.jpg For some reason the camera made the color of the Jeep more pink and bright than it is in person, Good thing with the duct tape grille block is in order to see it actually bent and weather worn you have to get under the Jeep like I did with the camera, up close it just looks like duct tape, and from everywhere else it looks like I used paint to 2 tone it. Won't last forever tho.. The license plate duct tape fell off from washing :( |
