Jaochin: Darn it--I sketched this mod when I got my DFIC last year--but the kudos always goes to he/she who brings it market first (no Alta-nertive for me!)
ANyway--better to be second cab off the rank than third, or fourth, so I got the airfoil sections from the hobby store this morning, and will put them on my DFIC when I remove it to install the thermal blanket.
Good one, my man!! Nice work--since I will be using different material, we can compare notes.
btw, my IC efficiency measurements are coming along really nicely. I've finally got 4 probes now, and really, it's the delta between the air in the airbox and the air in the intake manifold that really counts. Pretty constant +20 in traffic and +10 on the freeway. Airbox temps are never more than +2F of ambient thanks to the FAD!
cheers,

BTW, thanks for all the testing/measuring you're doing, i'm sure i'm not the only one who appreciates it.
FOR JOEL AND PHIL: The correct spelling of my name is: Joaquin
Thanks

Joaquin--sorry about the spelling (I actually do know it, but took it from Joel's post being lazy--sorry!)
The section is simple to describe: 1/4" short dimension, 3/4" long dimension, half round at front, tapered to small dia. round at rear. Exactly an airfoil section. I bought it from a RC plane hobby store in 3ft lengths for $6 each. I plan on cutting it lengthwise at the max short dimension to produce a hollow half round like yours for the entrance and a 1/2 long taper for the exit of the IC. I will JBweld like you and see how it flies
THanks to you, I'm all inspired again, even though it's been so darn cold here in the little Apple (cookie) that temperatures inside the engine are so darn cold... you could close everything off and it would still work.
cheers,

The airfoil sounds like it would work, just one thing though, if the sections you will be using are hollow it might be a little difficult to J-B weld them to the core unless they have some thickness to them.
Glad i'm able to inspire you again. I couldn't wait to get this done for two reasons:
1) I wanted to obviously accelerate the airflow through the DFIC
2) NAM has been kinda dead lately with stuff like this
BTW, no worries about the spelling, just messing with you and Joel.
Nice work, Joaquin!! Looks like it should do the trick!
For the rest, this would help on exit, but other's have answered correctly that a trailing edge like the rear of a wing would be the optimal shape. A wedge on the front end of an airflow would seem like a good idea, but it really isn't. Sharp edges like that tend to stir the airflow into vortices, which are not a happy condition when you want nice, laminar flow.

I'm still working on the outlets, I want nice, happy laminar flow.
Check with DrPhil, he found airfoils that should work.
But not as fun as your work, certainly!

Something fun? Hmmm... could be anything!
Good work guys. This is great reading--improving on an already great product. Grassroots creativity and inventiveness. (is that a word? If so, is it even spelled correctly?)
Anyway, keep this thread going!

Nice work Partsman ! Hd I known I would have packed my DIFC in my carry on when I came home for XMAS and had you work on mine. I wonder how well that would have gone over with the X-Ray security system ?

I should have brought you up to the shop where I do all my mods. The guy who owns it is a very good friend of mine(he even gave me a key to the place), I think he digs modding the MINI as much as me.

OK, Joaquin, here's my version. Airfoils dissected and (JB)welded on. Extremely light, and hollow for good thermal conductivity (!)

The exit foils:

and it's all siting on a M7 Aerogel blanket. New M7 boots to boot!

Measurements tomorrow...

Sorry, this public posting of photos is not my usual method. I've sent them to Partsman--I am sure he can get them up here shortly.
No time to drive today, but the install went well--Peter (M7) said those new boots were easy to install, and they are way better than my Altas. btw, my old boots looked pretty beaten--maybe they were leaking a little boost...
Ambient might be 30s tomorrow! Ouch.
The blankie is cool, too. Fits well, but there may be some problems with the big holes for mounting and the DFIC diverter--others will have to post experiences to see if there's a trend here.
Tomorrow, more.

Sorry it took me so long...
Very nice DrPhil! That looks like it should work...



The Aerogel looks pretty sweet too...

As a side note Phil, grind off the 1/4" dummy bungs on the front of both the inlet and outlet tanks, you're able to get a better seal that way. You can see what i'm talking about in my pics in the first post.

The boots were not an after thought, and as such engineered with a softer durometer silicone and less numbers of polyester ply's.
As for the gromet placement....It should fit perfectly as we tested them on 3 different cars, as seen in the first image.
