2007 Civic Coupe Modifications - Page 2 - Fuel Economy, Hypermiling, EcoModding News and Forum

Ok, so the results of the first part of the test, driving the 300 miles at 65mph with cruise control and no hypermiling. The result was my best ever gas mileage 37.29 with no aero-mods. I plan to add my fog lamp covers, upper and lower grill blocks and then drive the 300 miles again next week (same direction for consistency).

I understand this test does have variables, such as wind, weather, other vehicles, construction. I believe over the course of 300 miles, traveling the same direction on any two weeks, pending a hurricane of course I figure the variables will more or less cancel out.

Any thoughts on the test?

I'd like to see you just find a semi to draft for 300 miles!

Mythbusters found that you get a 40% reduction in FC by staying 10 feet behind.

That might be tough to do for 5 hours!

Have you considered deleting the passenger side mirror?

Here is the fog lamp cover that looks decent, the other side isn't quite as good and might need to be re-done

Here is the whole front end.

Opinions? I have the lower block done but I need to figure out an attaching method and get it painted.

Those covers look great (unlike that foam ... which brought me back to my firefighter days.)

Fortunately, my 4-door comes with fog light cavity delete.

Planning on wheel skirts? That's what I'd like to do ... if I could find the right aluminum stock.

Actually, after I finish the front bumper and the parachute under the rear bumper is where wheel skirts come in. I'm thinking around 2 weeks till I get to it, I could have more accomplished at this point except I'm trying to do some kind of testing to see the improvements which is hard cause I want to just do the work and make the changes.

I thought about the 4 door but at the time I was single and I like the look of the 2dr a lot better. I think it's funny that none of the '06 '07 civics came with fogs standard, only the place to put the fogs. I'm glad you think they look alright, I finished the lower grill block today I just need to paint and attach (maybe tomorrow if I finish up work early). Still trying to find a way to do the upper.... ideas are welcome.

how did you get the Coroplast to stick on over the fog light spots?

Looks great. Here are the results of my lower block testing on an 05.

The coroplast isn't "sticking" :-) it took me a decent amount of work to find a mounting method that wouldn't put holes in the car. What I did was take zip ties and cut holes in ONE layer of the coroplast, slide the zip ties in one hole and out the other. I have two on the big side, one on the bottom and one on the pointy side, the two on the big side go through the bumper and attach together in the back, the bottom and one on the point are attached to an I bolt that is fastened through a hole in the center of the fog lamp spot. I used the I bolt to adjust how tight the cover fit.

I have since bought nylon string and will be using that for the LGB on the corners with zip ties being used for the center around the license plate. For the UGB I have no idea what i'm going to do yet, I will try to get pictures of my mounting setup next time I'm messing with it.

Nice mods on the civic. I unfortunately can't install grille blocks during the summer because the temps here are already at 104 degrees! I attached some cardboard with painters tape and monitored my temperature and it started to overwork the fan. Any savings in gas were nullified by the engine over working.

I'm definately going to put it up in the winter though.

Been there, done that - almost.

8 hour trip leg from Olympia, WA to Boise, ID (521 miles) on less than one tank. Drafting about 2-3 cars lengths behind tall semis whenever possible and safe. Otherwise driving the speed limit (70 in WA, 65 in OR). Could have probably gotten 43 mpg out of the car if it wasn't for the extra weight (wedding presents and luggage), 8 hours on the road and the boring drive wouldn't have driven me insane. Still, 41 mpg isn't bad, right?
