To duct or not to duct...FMIC pix

[phunny]

Here's my setup so far and with the height of the FMIC I'm thinking maybe ducting might hurt airflow to my radiator. Opinions?

Ducting should never hurt airflow to your radiator. It's supposed to add a boundary between the heat exchangers and the large negative pressure zone under your car.

 

[Andy-gst/gsx]

Do a quick mock-up and put some miles on it and try...Id scrap the heavy bumper support thats for sure. Give me a call if you need some help...I got batteries all charged up in my sawzall with nothing to cut!!

 

[BoostedBeaver]

I thought the same thing as I bought the plastic to do some shrounding on my 1g with the VRSF. I added ducting anyway and it seemed to help. Then I started overheating. I checked the system to find a leak at the thermostat housing, soooo I will have to repair that tonight and let you know how my ducting helps/hurts.

The idea is that all the air going through the FMIC will never make it to the radiator without the shrouding. This is due to the low pressure under the car and all the lesser paths of resistance the air has to go. Although you see all of that space now, how much is recieving airflow with the bumper on? I noticed that only a very small portion of the top half was recieving a little airflow from the grill between the lights. Most of mine was block by the bumber, lights, and other misc things on the front end.

When I fix my problems and get all the air out of my system, I will let you know how it works for me.

By the way if you need the material, I used some plastic made by allstar part number 22400. Mine was black and .070 thick. It comes in a 10ft roll and is very sturdy while at the same time plyable so that you can make it fit your application. You will need a pair of tin snipes to cut this stuff. 99GSTracer brought light to this product in a ducting thread started by himself. Hope this helps.


Edit: On a side note that angle iron seems to be covering a few rows of the intercooler as well. Maybe trimming that so all rows are exposed (trimming the middle part of the angle iron) would also help to some small extent.

Is that condenser really dirty? It looks like it in the pic. If so, I would soak it down with a can of Gunk.

Duct it. I'll give a couple preview pics from last night before my new journal entry.
95% gorilla tape, 7% plastic shroud on bottom, 3% duct tape (ran out of gorilla tape)

Ouch on your finger man.

 

[Guilty1s]

thats a 105%

Here is my ducting .No more overheating on the highway after this.

I stabbedmy finger with a curved pick cleaning epoxy off of a bolt. So far I haven't raised over the first hash mark in the middle of the gauge. Fans are on 100% so yes, duct it

Yeah you're right, it's always easy to just remove if it does more harm that good. I have a sawsall on the garage floor with a full charge Also, I got the headers wrapped and waiting for the reinstall

With the fans I bought I was worried they would be working too hard to try and get the air through. together they are rated for 3000cfm

No dirt on her at all, just that color, I actually thought the same thing at first.

Nice and clean, good job man

LiQUiDx, I was wondering what type of tape to use and the gorilla seems like a great choice, thx

 

[LiquidX]

Charlie, when I pulled all of the old tape off last night I saw that there was only 1 area where the tape came off at from driving. I dealer the bottom of the FMIC tothe bumper and it must not have been enough contact and came off there. Everywhere else it was holding up strong.

Press firmly with it and get at least 1 of the large rolls. Don't forget to seal the radiator to the support using some foam pipe insulation. Looks like a pool noodle.

Guilt1, I just realized what you said haha. It's an above-and-beyond dcuct system infused wiu blood

It may be because i've had 4 hours of sleep and am about to go to class, but what exactly is "ducting"? I thought it was something completely different.

 

[LiquidX]

Ducting is just making a sealed pathway for air flow. Just like HVAC ducting, you are making air travel to a specified destination. In this case it's all about making the air go through the FMIC and have a majority exit through the radiator and not out through some hole before the radiator.

Ducting alone won't solve over heating on most setups unless you have a duct scoop after the FMIC. Having high flowing fans are what will keep the temperatures in check as well as having a good radiator. Not all radiators are made the same.

There is a lot of good info on the site and a lot of different setups for how people made their ducting. My first 2 versions used the stock duct work and my latest uses pretty much just tape.

 

[phunny]

I am curious as to what the resistance is going to be since I am very close to the 30 amp capacity.

 

[canada4g63]

Just get some high flowing cfm fans i have a 14" and 12".

I have 2 coming that should give me around 3000cfm. Here is the thread I started on the new fan setup

[DaRKSiDeGSX]

IF you don't have A/C would you be able to wire the A/C fan to the other fan, and raise the fuse maybe 5-10 amps? This would give you an additional fan for free...

 

[LiquidX]

Yup, you can wire it directly to the other fan. I've done it multiple times already without extra fuses or relays. I did it with my Mishimoto fan and shroud kit (crap CFM flow) and now with my 2 SPAL fans.

 

[DaRKSiDeGSX]

I'm glad I read this I'm going to do a little duct work, link that spare fan, and seal the fans to the radiator so they are forcing air only through the radiator instead of the radiator and the gaps all around the fan shrouds.

So then would ducting be what that white 2g gsx, can't remember his name, did for road race when he sealed it off with sheet metal and then had it coming out a opening in his hood?

I love that setup but I have no room for that. I have a little over 2" clearance on the drivers side

 

[TSi Kid]

Yupp that's the one I read haha
Such a clean setup.

Get creative and do your own. Never say never

Ive been looking at doing something similar to that. Did you leave the top part of the duct open like that?
