Nice work!
|
...yes, very nice work!
|
Looks great! Going to have to figure out how to block mine out pretty soon while still staying incognito!

I'd say 21 days is well worth the wait. It looks like you put a lot of effort into this.
Just want to ask about airflow. Under the hood and above the new grill block is a small slit. Does that allow airflow through the radiator, or that blocked further back? Does the scoop allow airflow into the top of the engine compartment? On my 4Runner, the scoop is blocked inside, which doesn't allow airflow (for anything, let alone cooling). What about underneath the air dam? Does the radiator go down far enough to allow the air that does end up under the car to run through it? Do you have a belly pan to stop that flow? I'm just wondering if there is any airflow anywhere in the system. Very nice work! :thumbup: |

http://quirk-images.com/ebay01/subar...00U9-a.jpg.jpg here are my instructions on how i removed my upper grill (without having to remove the front bumper). the procedure might be similar for your car. http://ecomodder.com/forum/389371-post64.html |

Yes the sti has FUNCTIONAL ;) hood scoop that feeds the top mounted intercooler :D. The "slit" on the top doesnt lead to anywhere, its blocked from behind. I am thinking of making a small plug for that area too to increase laminar flow. Yes, there is a front FLAT belly pan from Subaru for smoother airflow down there. However, the issue seems to stem from my larger lower grill block. Back when i was doing my "early" versions of upper and lower grill block, 100% upper grill and 80% lower grill did not effect engine temps at all. Therefore, i am going to trim my lower grill block some more to increase air flow to the radiator. |
This looks very nice. I appreciate the effort you put into this.
Could put an STi sticker on it, and no one would know it wasn't stock. |

looks nice to me.

Nice work.
I was reading this thread thinking I wish I could use our 3D printer here at work and go into the grill block business. |
That looked quite nice on the pictures. However that is lots of work and takes skills to get smooth surface.
If you use 3mm thick ABS plastics that has etched surface you can make this kind block in a hour if you have praticed or about three hours if its your first time: https://fbcdn-sphotos-e-a.akamaihd.n...82983496_n.jpg Upper block from behind... https://fbcdn-sphotos-h-a.akamaihd.n...85033745_n.jpg Total looks of the car. Beginners guide: 1. To shape the block first cut right size paper/carboard block 2. transfer the lines to ABS plastic with pen marker. 3. draw the line with sharp knife plastic on the floor. Once is enough. 4. Bent the plastic and it will break along the line 5. fit to the car and fine tune cutting off small pieces with knife. 1mm is easy but up to 3mm if you have sharp knife and right technigue. 6. mark ziptie positions with pen marker 7. drill 5mm holes 8. Make about 50mm hole for outside temperature sensor 9. Install and enjoy I just measure and build without template and it looked like that with first try ;). |
Any updates to the mods and your averages?
|
so the original poster:
no issues with cool down? with the radiator? |
I monitor my water temp gauge via the torque app
Normal running temp: 186*F with grill block: it fluctuates between 188-205*F the cooling fan on the sti does not kick in until 215*F. No overheating issues thus far! |
I dont want to hijack the post but The ABS if reinforced may just be an answer for my rear wheel skirts. I want them to precision flush mount into the opening, but be easy to remove for tire failures. Cutting a few zipties is a better answer than ive been contemplating so far; and much cheaper than push pins.

Looks great! I did the same with mine last summer. I had issues when it came down to the final shaping. Luckily USC Icing does a great job of filling pinholes.

the perfectionist in me is still unsatisfied on how my upper grill block came out....its too bulky, heavy and "wrinkly."
http://i101.photobucket.com/albums/m...0_IMG_2509.jpg I'm getting better at fiberglassing now and learned that the better i prep in the beginning, the better the result. For version 3.??? i lined the outer edges of the upper grill opening with double sided tape and tightly wrapped a tshirt around the whole thing. This way i should hopefully have clean edges, no sagging, no need for expanding foam, and minimal sanding. I'm also putting on more layers of resin for strength so that it should not crack when i remove the grill block from the grill. http://i101.photobucket.com/albums/m...326_164618.jpg http://i101.photobucket.com/albums/m...327_090146.jpg http://i101.photobucket.com/albums/m...327_090311.jpg |
updates
Resin came out pretty smooth, I shouldn’t need to sand it that much
http://i101.photobucket.com/albums/m...i/IMAG2849.jpg I also bought myself a rotary/dremel too (my first power tool!) to let me get some really nice details around the Subaru emblem. http://i101.photobucket.com/albums/m...i/IMAG2854.jpg http://i101.photobucket.com/albums/m...i/IMAG2853.jpg |
Looks good. If you want to make it really smooth spray a guide coat (super thin layer of a different color) on it and sand it down to see your high/low spots. Fill in the low spots with some body filler.

Thanks Daox!
yes I got spray paint and bondo ready to go! Just finishing up the edges and final shape. I spent 3 weeks sanding down bondo on my previous grill block :(. This time, the base resin layer is already pretty smooth, so I shouldn't need as much bondo this time around. |
Finished!
Finished!
I got a small bonus at work so I splurged on a power rotary sander. Cut down sanding time by 90%. Now I can get the smoothness I've always wanted. http://i101.photobucket.com/albums/m...i/IMAG2992.jpg http://i101.photobucket.com/albums/m...i/IMAG2993.jpg http://i101.photobucket.com/albums/m...i/IMAG2994.jpg |
This looks very nice sir! Well done!
|
Looking forward to seeing it installed!
|
Pictures as promised!
The edges still don’t sit as flush as I’d like. Maybe the fiberglass/resin warps over time as I keep sanding? I tried putting a heat gun on the edges and clamping it down. Then as it cools, it sits more flush again. But for some reason, over time, the edges start flaring up again. That’s why I decided to move the mounting holes to even farther to the edges. However, im very pleased on how smooth the “face” came out. http://i101.photobucket.com/albums/m...i/IMAG3010.jpg http://i101.photobucket.com/albums/m...i/IMAG3011.jpg http://i101.photobucket.com/albums/m...i/IMAG3013.jpg I’m thinking of Plastidipping the Ecomodder logo in the middle http://i101.photobucket.com/albums/m...i/IMAG3014.jpg http://i101.photobucket.com/albums/m...i/IMAG3015.jpg |
It's looking REALLY good!!! I like the idea of putting the ecomodder logo on the Subaru logo! :)
Is that an air outlet on the fender right in front of the wheel? The reason why I'm asking is because you blocked off the lower corners of the bumper, which I would imagine is where air is allowed to go through into the air outlets on the other side. Maybe it's better to leave it open and use the block to guide the air into that outlet??? |
