I may still have the one I did at the shop, i'll take a look.

 

That sounds like a good idea! might just have to get a second hand cooler and try it. more on the bringing the under bonet temprature down, someone also suggested using the passanger side( in my case driver side) vent to vent some hot air out. would this not also contribute and in my case having a OE IC not mess up the flow thru the IC?

 

I know that carbonized fabricated a "hot air extractor" for the passenger side vent, here's the thread...
https://www.northamericanmotoring.co...extractor.html
...that guy does some incredible work.

 

This is one of the threads that I follow religiously because of an ongoing project of mine. My reasoning, after reading a lot of threads about it, was:
#1 : Heat soak is the ennemy.
#2 : The OEM IC is hard to beat, both in term of cooling and recovery.
#3 : Air flow through and around the IC is the key to the "holygrail".
I started with tilting the IC, now I just learn that Partsman has done it before (so mutch for original! ). I cut the IC's end tanks off right past the widest part of the "cone", fabricated some filler pieces and welded back.
Got an extra 9 degrees of tilt, still fit under the hood with room to spair. That should help with the 1st part of #3 along with an "optimised Bahamascoop" on top of the IC.
Now for the 2nd part of #3, I made a complete duct around the bottom of the IC. It is molded straight on the engine, sealed to the IC's sides and should keep engine bay's heat from getting to the IC, #1, and scavenge the hot air through louvers in the hood, #2 and #3. Made a new ramp/deverter in front of the IC that fits my modified M7 scoop, and, and, and.... it's endless . Lots of work still to be done, lots of projects getting in the way. Dr Phil and Partsman thanks for the kind words on my thread, be assured that I think the same of your work on this subjet.

 

Pics, we need pics,

 

+2+ !!

Being the molding whizkid, carbonized, I'm sure this is not only going to work, but it will look fantastic too!

I, too, have an OEM IC sitting down in my shop, and every time I pass it by it seems to whisper to me about inlet and outlet scoops...

 

Thanks for posting carbonized...great minds do think alike.

I agree with Jim and Phil...you definitely need to post pics of your molded duct-ramp-diverter. I would love to see it.

...and yes, it never ends.

 

I love this thread... it's crossed over from mere obsession to something else altogether...

I think I'll just stick with water/meth injection...

 

Thing is, the better we can get the IC to work, the less we would need to use the water/meth to work, saving money

 

Hey Partsman, did you ever find one of your modified IC's laying around?

 

I was up at the shop on Sunday cleaning my air filter and looked around for it. It was cut up/sacrificed for a IC project I was working on a while back...a direct flow intercooler per M7's design, but with the lightweight of the stock IC. I have since moved on from that to fabricating a FMIC using an R56 IC core and custom end tanks.

 

Ok, no prob. Thanks for checking .

 

Some pics, Remenber this is a work in progress,(slow progress) the first pic is dated december 07. And pretty rough.


That's 9 degrees more than original.




The bottom shield/ duct.



top "Bahama scoop", side view



Big mouth



The escape side



The whole IC will be ducted.


The duct is made of 7781 style fiber glass/ hight temp epoxy. scoop will be reenfoced with carbon as it is flimsy right now and it is on the cold side. I choosed fiber glass for it's better insulation properties.

 

All I can say is...WOW! Even in this unfinished state it looks amazing!

You are truly an amazing craftsman...excellent job! Thanks very much for posting.

 

I want one! Please tell me you are going to market this

 

I don't even know if it works and there is the hood with louvres, and the connection to a moving engine,and this and that... . All I know is that I could blow all kind of a storm at the intake manifold without bugging the IC air flow witch is the topic!

 

Really nice work. That thing should work really well. I assume the air will exit out some king of vent in the hood? From your other work I bet it will look awesome as well.

You really have some serious skills men .

Longboard

 

Thanks Longboard! Funny nobody noticed my welding skills!!

 

Oh I did but you got a pass because of the other work .

Longboard

 

Well, I'm a bit rusty with old Al, but it passed pressure test and it's smooth as silk on the inside!
Did I just say that?

 

Can't wait to see the finished product

 

Of course the proof will be in the field test but I see some possible issues. The tubes and fins create obstructions that contribute to high pressure in the chamber above the IC. At some point, a stable flow rate through the fins is reached, and air stacks above the IC, no matter the capture improvement, additional air mass won’t fit into the chamber. I’ve seen water spray reverse out of the OE scoop, which leads me to believe this is what is occurring. Low pressure below the IC encourages evacuation, but if offered no exit other than at hood level, it will encounter high-pressure laminar flow current. Drive through rain and you will see slow moving water clinging to the hood surface. This may create impedance to positive flow, or perhaps reverse flow, causing a non-productive vortex effect, or maybe a stifling equilibrium. The engine bay under a non-vented hood relies on the low-pressure area below the exhaust manifold to encourage thermal evacuation. I’ve looked at under hood temperatures and noticed a rapid drop towards ambient once in motion. From that data, I could not see a reason for hood vents, and it makes me wonder what effect they would have on the overall aero dynamics of the vehicle.

Just for whatever it’s worth, NAM member bomboasy created a tilted OE IC and integrated diverter almost five years ago, but not the level of sophistication as carbonized’s.

 

I agree about the field testing proving it out. Air moves through an IC due to differential pressure. We usually rely on high pressure in front of it pushing the air through. Even though the flow path looks better, if you by chance crate a more equal pressure on both sides of the IC, flow will decrease.
I'm not trying to rain on your parade as we all wish there were ways to make the IC more efficient, but some back to back tests will be very interesting.

 

I got an average 3C inlet temp drop on the move with this scoop but it held in the heat in traffic... your design is much much better so be interested to see the results. Nice work

 

Can you share your data on this and how you measured the drop in inlet temp?

Thanks
