Mounting Coroplast for a Grill Block
Now, I'm going to pull my bumper today so I can respray the black portion of it to make it look spiffy, and I picking I'll grill it up as well. What do people usually use to mount the block on there? Is there anything that perhaps will not require mutilating my bumper?
|
No mutilation, eh? Dan used screws on the Del Camino. Looks like basjoos siliconed his on :)
I ended up making a kind of bra for mine to avoid that same vexing issue. |
I've never seen pictures of your bra, but I'm prollygoing to hot glue or something. I imagine it'll peel off...
|
I just made it recently. It's not totally finished. When it is, I'll post some.
It's just a rectangle of black vinyl-ish material with a couple of square holes to let the air through where I want it. Works for me since my car's black. Keeps the bugs & stones off the paint too, I guess. |
I made a piece of angled sheet metal and attached that to the bumper skin from the underside. I then screwed the coroplast to the angle pieces. For the bottom I used mastic tape. Mastic tape is a roofing product its sticky and stays malible, kind of like silly putty but stickier. Its also sold under the brand "tacky tape".
By doing it this way when I remove the block no screw holes will be visible. |
I've figured out how I'll do it. Was about halfway through when I punctured my knee with the knife and went to the doctor's. I'll finish up tonight when I can walk around and stuff, :)

Nah, that's okee. If you want to enjoy some good pain you can stab yourself.

I attached my plastic grill block on with zip ties, and black pollyurithane roofing calk, the little bits are 100% held on with roofing calk, and the larger one is zip ties with roofing calk to make it look seamless, I caught a co-worker looking at it one day, baffled at how good it looked.

I still have to do the aero mods on my civic.:(
It will take hours to make a belly pan and the grill block.:mad: |
Leg
SVOBoy,
I knew a guy that was putting a shift kit in his C4 tranny and drilled a hole in his leg while drilling out a hole in the valve body separator plate :eek: He was in to big a hurry to go in his shed and use his work bench. Are you two related? |
I used the technique as outlined is this post.
https://www.gassavers.org/showthread.php?t=701 I had to drill small holes in the grill slats but the drywall screws seem to be secure. See the following link for pics. https://servercage.com/wordpress/?cat=7 I cut the hole in front of the radiator ~3.5" x 4". I recently went through some hilly terain in VT and experienced some level of overheating. I had to put the heater on going up the longer hills. I might open it up a bt more but the temps are getting cooler around here. Sean |

Awful.

Maybe I should have called it the "bro"... or what's the name they used in that Sienfeld episode? |
Manzier.
|
Looks good.
|
Thankee. I repainted a tiny part of my trim for practice and it looks lovely. Car will look brand new when I'm done, :p
|
Excellent. How did you attach the foam and Coroplast?
|
Looking good! Are you going to make a section that you plug the hole in the winter time?
|
The foam was just to mock up more easily, but as you can see in the 5th photograph I put little wedges down in the two holes and glued those to the sides, then the coroplast to the top.
For the center part it just kinda rested and I glued from the back. |

I like...
Sweet! I am looking to do the same to my del Sol. I can't wait to see your mileage delta from this mod.
Very nice work! |
I'm not even sure if I'll be driving the car, :p, though I'd love to see a change!
Have you seen dan's grill block on the old del sol? |
www.crxmpg.com/grillblock.html for the full write up. Won't post it in the diy section here since it's been covered enough, unless someone wants me too. (Besides, we already have this thread.)
|
Bumper is in my garage. Pick up my coroplast (corigated plastic as per the sign shop) tomorrow for $11.22 for the 4 x 8 sheet. Hope to have mine on this weekend. I am thinking of putting in no holes. Has anyone gone no holes?
|
Your coroplast is cheaper than my coroplast
Just picked up another sheet for my undertray for $18 + tax. :( And I'm going to have lots left over. I could have bought a bunch of little scraps and knitted them together into a patchwork, but decided to just do it big. |
Here is mine.
Just got 'er done. Got my foglights installed at the same time however I didnt yet wire those to the switch due to some problems getting the wire into the cabin.

Doing a Grillbock
I plan to do this as soon as I can find some coroplast.
I have an 88 CRX and the front end looks nearly the same as Ben's over on his writeup : https://crxmpg.com/grillblock.html You can see from the pictures of his front bumber that Ben's intake space is divided into 3 horizontal sections. He covered his by leaving a square opening in the middle. Mine is divided into two spaces : https://xs106.xs.to/xs106/06366/DSC01187.JPG.xs.jpg The red outlined portion is the area that I would like to block off rather than leave a square opening in the middle. I think it will look a bit cleaner. My radiator spans the whole width of the intake area and I would effectively be blocking off roughly half of the area. I live in Maine and it's been average about 65 or so during the day and dropping to the forties at night. I have a 21 mile commute but never get up over 3k RPMs and usually cruise at 55 MPH @ 2.5k RPMs (I have an automatic). The temp gauge on my dash always reads at 1/3 of the way up. Do you guys think that it woudl be OK to do this? Any comments or suggestions will be appreciated. |

I have everything blocked except for a 4x2" area for the summer. I run completely blocked in the fall, winter and spring. You should have no problems.

Danger Will Robinson!
I had my 3.0 L overheat in winter messing around with blocking the front. Has an air dam and a rad that is slanted forward at about 45*. I covered the opening thru the dam where the air is forced in by the car's movement...but it was still open below it. Problem is...this area is actually under a partial vacuum caused by the air dam. No damage, but it was close. If you don't see a lot of steam and bubbling it should mean that you didn't get it hot enough to create pockets of vapor...which is where the damage is done. Vapor doesn't remove heat. |
I'm just wondering if there isn't a problem with your cooling system. I have some long steep hills that I regularly drive with no problem.
