Well my IC is currently off, and seeing as it has been so long since that happened I had a bright idea, why not clean it while its off ....

















So I start cleaning it and well for the last 15min she just been gushing oil (well maybe and exaggeration but I'd say there was probably close to a 1/4 of a quart in there) all clean good oil but my word how was there room for the air to pass through, can't stay long as I need to go and change the paper towels soon.

Also I took the time to get some 2 hours cold eninge bay temps with the IC off 150 dgree on the block, 115 just behind the radiator and 88 in front of it so there is definately room for improvement.

 

You guys are on the right track. By the end of next week I hope to have an aluminum working model.
If any of you remove the devirter from the scoop & you find that the under hood temp is better, please post. It has been cloudy & cool here all day & without that black thing.... seat of the butt feels good, real good....

 

Weren't the M7 guys working on something improve the airflow...
the curent IC has to force the air down verticaly through the IC -
The M7 design was going to arrange the IC core so that the air flow would be more horizontal and straight through ?
Anyone else heard of this ?

( this makes your pic look like a CAD drawing )

 

Yup, the M7 guys IMHO have a great solution.
I think most of the guys here want to improve the stock unit.
How do you post a picture here??

What I REALLY want is a DFIC.

But, until money grows on trees, (or my fiancee lets me) you are right... just trying to improve the stocker!

 

To boldly go where no backyard engineer has gone before.....

 

Ahh yes the grass is getting a bit tall, the MINI seems to keep taking priority

I think having an engineering team through NAM has provided a good flow of ideas and witht he CAI project has managed to make a tangible and measurable differance.

 

And there is something to be said for us backyard engineers...

MINI engineers came up with this stuff with degrees from MIT or the like, and a budget that would probably make my salary look like chump change...

Us backyard engineers have some duct tape, a scissors, and a multi-meter with less then $100 budget. Yet I think we're coming up with some pretty cool and useful ideas.

 

This is true, I'd like to think we are doing just as good a job at it too, assuming MINI were to desgin a car purely for the enthusiast. Guess the engineering courses are paying off

I'm hoping to have a cardboard mock up done by tomorrow afternoon, I want to do some reading up on the previuos run at a hood scoop (which I believe is now the CF M7 Ram Air). Mainly to refresh my memory, but it seems like I;ve got homework again, only this time its fun!

 

"And there is something to be said for us backyard engineers..."
Yup...Jim Hall comes to mind... Look what he did in a small garage

 

Well, in a nutshell I think my home breww solution was a partial if not total bust
Nothing ventured.....

In brief; went to an auto-x event today. On the way there I left the cooling kludge in place. 74º and almost all temps were highway cruising at 70 mph and some were at a 45-50 mph cruise.

Avg efficiency was 50.75%. Not stellar.


On the return trip it was 87º and all other conditions were as close to the same as I could posibly make them. The change was that I installed the hood seal back to it's place and only used the insulation as a barrier to fill the gap between the radiator support and the engine.

Avg. efficiency was 57.5%. Much better.

Next step, build a better barrier and then test with and without. Then steal ideas from the rest of you guys

 

Further than I got; ended up getting and going for a 6 hour drive with a hike in the middle to salvage the day.

Remember it took Edison 1k times to get the light bulb to work.

Now I've got something to whistle while I work.

 

Since I am lazy and don't feel like reading all 3 pages I thought I would quote this one section and bring up something that someone else may have already (if so I apologize).

I agree with what you say in that the air is coming in from multiple places, not just the scoop, for the stock IC.

This is why I went went with the m7 DFIC because it only gets its air from the scoop and it exits from the rear of the IC.

Page and a half, and we have self imposed backyard engineering bugets of $100 but an unlimited design team here on NAM. We all like the functionality of the DFIC, but are looking to get much better results (if we do it right even on par with the DFIC if we work hard enough) out of what we already have. Even some of the insulating topics discussed could help a DFIC with heat soak issues that any top mount IC suffers from.

 

Here's a summary of this thread for you.----------------------

Big budget and little thought = M7 DFIC.
(Edit: On the buyers part, not M7s... M7 was genius on the DFIC... don't want to get flamed by M7 and the boyz)

Big thought and little budget = This thread.

 

WEll I started drawing out my idea in PS and realized that even though I;m looking to improve the hood scoop to get the most cooling air, there is some nasty airflow off the bumper and the grill can go two ways into the engine bay then radiator and over the engine or it can be defelcted upward toward the hood scoop and into the IC one means we've got more air going into the scoop so the battle of air going downward through the IC is easier won, the other has more air into the radiator so the air on exit is cooler, not really sure which is better yet. The photos I'm including show wha t I magine air flow to be on the stock setup and what a hood scoop mod airflow would be (I'm hypothisizing on both) In the second photo I think a big deal is to capture the air that passes over the hood scoop and to take the air in there and get it into the IC asap. What the first photo doesn't show clearly is boundary layers and the fact that even though much air passes around the scoop on one layer gets in the rest get pushed over this means more drag and less cooling an outward and downward reaching scoop will harnes the air and capture multiple layers if we're lucky. Also I noticed that some smoothing of air off the bumper is in order, if we could get all the air pushing off the bumper to cool the radiator down low then block off some of the upper grille I think we may find a decent comprimise thinking in type, tell me what you think.

 

Will someone PLEASE explain how to post a pic....

The M7 Ram and Extreme products do the same thing. That's the easy part.

 

See #39: https://www.northamericanmotoring.co...=1#post1006082

With my BBR bonnet scoop and stock IC I record practically the same air inlet temp as the M7 DFIC!
