FMIC air flow, cowel, scoop, traps,funnel effect or forced vortex induction IC

[ShadowWorks]

I was having a chat with my boss and telling him about my FMIC project, he told me unless i have real air flow pass through the IC then it wont be super affective at removing heat.

"I said its at the front of the car"

he said

" behind a bumper boy, that will not direct air flow through it, the IC will get lower pressure eddy currents not big glups of forced air running through it"

So he tells me to design a scoop for the FMIC, a ground scoop that will direct air flow into the fins, so its like a satellite dish for the signal or one of those dogs that has those funny cones around their necks!

He said an IC would be more affective if it has forced cold airflow going through it over a larger one with poorer airflow going thorugh it.

The funnel effect or forced vortex induction or something like that, sounds mad i know but i think there is something to it? i will give it a test and see what happens.

Has anybody made a funnel, valance, cowel or scoop for there IC?

Your boss is right mate, but still a FMIC helps ALOT, so go for it!


But you can get a better air flow, by cutting a hole where the plate is supose to be.

The Saab 900 Airflow Kit has/had a air dam that did just this Kass, but i will be buggered if u find one, from what i here it was the most flimsy part of the kit.

The black plastic thing in the middle:

At some point i'll be increasing the size of the bottom lip to force more air up through my FMIC, but i have'nt suffered from lower boost because of saturation yet so although a better ait flow will probably improve thing's even more it's not completely nessesary.

Kaas who is that guy that had done all that cutting of his bumper and he has 2 hood scoops

A man after my own heart, the only problem is where would i put my license plate? the cops would bust me right away

I would love to do this kind of mod as i have the front of my car off apart from the head lights.

But am not brave enought to do this to be honest, i dont have a spare bumper should it go badly wrong, and i just cut off my tow hooks and the bumper guides, not the bumper bolts and this had made me worry if it does not go right.

Si the funnel is something to do with lowering the IC temperature, apparently ever 1 degree less in temperature means more horse power! so a 4 degree drop means much more power, even if you dont have heat soak or noticed boost drop off, the air will be denser and cooler so much more affective.

The air kit does look kind of flimsy but i would love it all the same, i have tried to buy the bumpers twice on ebay and both times i got fruadsters!

I've cut a hole in my front bumper too. Fortunately, we don't need to run front plates in Alberta. But how about you get a North American shaped plate made up and then mount it off to the side somewhere, Lancer Evo VI style? That's what I would do.

[ShadowWorks]

Hi Vince can you post a picture or a link to a picture?

Would be nice to see what you have done.

I dont know if i can get a side plate for the 900, getting it is not the problem, checking if its legal is.

Just an interesting side note but i just drove 3 miles to delivery a parcel and seeing how i have no bumper on my car which is illegal but i took all the back streets and the radiator is totally exposed and there is a nice gap for the standard IC i decided to boost really hard and no heat soak after 3 boost, and i could not get the water coolant temperature above 55 and that was at idle at a set of traffic lights.

While driving the temperature dropped to 50 again, thats not normal, the car normally sits at 60 to 65 degrees.

50 degrees C is where my after market gauge starts to read so it was sitting on butt really.

Seeing how winter is coming and the air temperature will drop to sub zero, maybe a super chilled radiator is not needed so i could cover part of it up, but i cant complain about a super chilled IC.

I'm going to do this once I can get another bumper to play with, its a easy mod..

but I already get plenty of "air" into the FMIC....




if you remove to centre bar & slats from the grille it helps too

Paul i think you would see better results if you removed the plate and chopped up your bumper.

The main body of your IC core is behind the bumper so imagine the benefit.

I have cut away the bottom part of my bumper just as you have in yours, but its a bit flimsy now , I am thinking about making my own lower air dam for the bumper, am not much of a sheet bender but anything to get the drag down and make it look like a Locamotive i just love snow plows

The guy is from Sweden and calls him self popeye http://popeye.rty.nu.
I know the page in Swedish, but its still good!

SHA: Cant you just mount the plate on the lip in the buttom?

[Vince T]

Hmmm...the only pictures I have handy are these:

http://www.ultraviresmotorsports.com...front-long.jpg

If you brighten it up a bit, might be able to see it a bit better.

But basically what I did was cut out a section of the reinforcing bar and also the foam. Then I added the mesh plus some sections of black puckboard (the stuff used to line hockey rinks) to cover up the exposed foam and metal. There's also some puckboard underneath and to the sides of the FMIC to help channel air directly to the IC's core.

[ShadowWorks]

Popeye! does he have arms like popeye? i think not

I like his 900 mods, shame his stereo system is junk.

I wish i could have just mounted the IC below the bumper, that was the plan, but over here we have too many speed bumps on the roads and if i ever hit a speed bump even at a slow speed that would burst the IC and game over basically.

So i decided to mounted it behind the bumper but i had to cut away so much of the steel, Alan tells me its normal and nothing to worry about

The only other problem i have is its very cold now in Scotland and the massive vacuum hose i got does not bend well in the cold, they are rated for 100Psi and i should have gotten thinner ones, its too late to cry.

This better be worth it dame it

I took out the stock IC and removed one of my batteries and i have the space to start the work but its been raining like crazy for over a week! plus my street light is not working.

I had to plumb the Turbo pipe directy into the throttle intake and guess what,,, the turbo spools up so fast and the boost level is the same! knock comes in at the same level, i even blew a cuff off at 16Psi.

I am starting too think the stock IC is a joke?

Has anybody run a T16 with no Intercooler? my dump valve was much louder with no IC and i didnt feel any heat soak? but i only went up and down mt street.

Your car looks very nice Vince, wish i could drive without a front plate now, it looks clean and smart.

What are the side vents that popeye has on the hood of his car?

Hi mate,

as already said this mod is on my "things to do list"

just need another bumper to play with

I dont know what those side vents are for, but I think its just for looks


SHA: Then you scould see my stereo Its stock speakers and a cheap MP3 player I had a brake in for some years ago, in my old car, so I have not been thinking on getting a big stereo againmjust now, but I woulk like some stereo that gives better sound than stock, but I have to be installed, so it cant be seen from outside. But I dont know what it has to be!

[uberfast]

I don't have a fmic, but I agree with what is being said on this post... the bumper does restrict airflow. I removed the bumper from my car and I got incredibly lower engine temps as the radiator was getting more airlofw to it. And now there is a nice little opening which I can fit a fmic in like si did.

[ShadowWorks]

Kaas that why you need tinted windows at night its almost impossible to see in but its easy to see out, what you need is a stealth system, that means everything looks normal until you sit in the car, you cant see any speakers or anything fancy, and never play the music loud around your own area as thiefs notice these things.

I think the side vents on the hood or bonnet is to let the hot air out, because you can cool parts down but the air has to go some place right.

I have to take my last comments back, without the stock IC i did notice today that there is less power in the boost even though the boost level is the same.

The dump valve is louder but now the car feels softer because there is only hot hot air getting into the engine, so IC are better than direct hot air even if the spool up is less.

I also seen a cop drive by me and hit his breaks! i knew as soon as he did that he was going to come after me so i floored it down a side street and he had no chance to get me, boy did i feel stupid!

Right am off to do some work

[spg1]

What I would like to know is what kind of car did he get the side vents from, any Idias?

[saabchilten]

they look either aftermarket or custom to me.

[ShadowWorks]

Those side vents are aftermarket, they do not look to bad to me, gives a fish gills affect.

I have taken Kaas advice and tried to mount my IC just under my bumper, i was not happy about it being behind the bumper and no amount of work is going to make me happy back there, so i had to cut the aluminium beam inside the bumper i only removed 1 inch in height but its made a huge difference in the installation and height of the front moutn IC as it will be on the outside of the front bumper now and not behind, very Japanese

I had no idea the aluminium beam in the bumper would be 8mm thick! It took me 3 and half hours to remove a 1 inch by 30 inch section and 4 drill bits and 4 dead jig saw blades its 3.07am, my back hurts my hands are shaking and i have a ton of swarf i need to clean up.

It will look great when am done, God knows if it will be any good, fingers crossed
