Me think I 'm gonna go Dr Phil's way , no bonnet cutting for this wimp and I want these 20 ponies . Anyway it looks relatively easy to make and just as easy to delete if not happy. Thanks Dr Phil

 

PM sent...... I want one..... it looks very serious and nicely done.... thank God for the passionate souls..... or is that compulsively obsessed, I keep forgeting.....

 

OK, as you all know, I'm an economics professor...read dork. I can't make more than one of these, but I'm happy to provide drawings for those interested in fabricating their own, or working with someone to do it. I will do some drawings and put them on my website. There are a few things to consider:
1. You need to have a really big hole scoop, or make one. My custom scoop is significantly bigger than even the DFIC scoop to provide lots of air to the DFIC and a reasonable share of the opening (about 25%) to the fresh air intake diverter.
2. You only need to cut away some of the bonnet liner. If you have a sealed (with a metal top) airbox, you'll have to think of a way of mating the airbox diverter to the airbox top. I think it would be pretty easy, but my setup allows me to use the existing Alta gasket to seal against the airbox diverter.
3. The diverter, which attaches to the scoop, doesn't move, and uses the bonnet as the "4th" side. This is good, but it means it has to clear all moving parts, which I've found to the the DFIC itself and the clamps that hold the flexible boots to the IC horns. This is perhaps the hardest bit of fabrication, as it's trial and error. The rest can be done with simple tools (I used a nibbler to cut the Al sheet,) and a whole lot of patience.

I'll try to get the drawings done this week.
cheers,

 

Nice work Doc. I couldn't help but to laugh...you need some probes for your butt dyno?

I can get it made....... actually I have a CF fabricator here in town that loves custom jobs.....

Thank You Professor

 

While I am sure that it has improved things and I love your work - 20HP SOP gain? Like a shot of nitrous!

 

Bart--you got me! You're right, this is a little bit of hyperbole. But...I really feel as if it's a more perceptible improvement compared to my relative disappointment moving from my modified Alta IC/diverter/scoop to the DFIC. Of course, I now have a bigger scoop, a new IC diverter, better seals, the airbox diverter and some thermal insulation. Maybe it's just all coming together. And the ambient temperatures are 20deg lower than they were 2 months ago!
Just goes to show that the ScooperPooper dyno is a little subjective.
cheers,

 

Boy, I get caught by my own word play! Now that I reflect upon it... Actually, my reference to the ScooperPooper is a very indirect acknowledgement of a wonderful documentary I saw on SpeedTV about the TransAm Audi Quattros. They interview Hans Schtuck, and talks about driving with very little padding on his seat, so he can feel the car "through his popo." He says it so delicately, but it's like a reference to a childhood memory or something. Very quaint. Anyway, every time I see someone mention the butt dyno, I always think of Hans and his popo.
Maybe that was too much information.

Anyway, I want the probes for measuring IATs. There was once rumor that M7 was coming out with a kit like the VR kit. I hope so.

 

DrPhil,

A big thanks for all your work and ingenuity! I have a stock IC, hood scoop and Madness CAI but really want to give this a try. Will updating to the M7 RAM scoop be the only required purchase for this?

Glad you didn't take it wrong . I truely believe you have improved things - reason I am following the thread. Plus I love experimentation and you are deep into it! Every little thing helps and no doubt your items are adding up.I just didn't want to see this work lose credibility. I am surprised (and releaved) you haven't been humped by 100 posts.

Welcome back to planet earth - now get back to work

 

OK, my airbox diverter is for a DFIC, since there's about 30% of the scoop area not being used (directly) to flow air to the IC. My airbox diverter opens up the remaining part of the scoop and sends that air to the CAI.
If you have a stock IC you can still divert air to the airbox, but you'll have to use the method that is being developed by Randy Webb (see thread on RAF and WMS airbox). Randy's diverter, (I'm surmising here) takes air from the back of the stock diverter and diverts it via a duct to the side of the airbox (his airbox.) He uses a stock scoop also, I think, even though I'm sure it would work with all stock width scoops (all M7 and Uber).

You could take my idea and fabricate a diverter to work with a vertical flow IC and modified IC diverter (remember the diverter simply guides the scoop air to the IC and seals against the bonnet.) But you'd have to do the fabrication, sorry.

cheers,

 

Looking good Phil. The scoop is the key. It will work with almost any IC, VC or DFIC. Here, we have rain and a plug could be used for the air passage to the CAI ( like yesterday, heavy rain).

 

Thanks for your input. I think this can still be done with the stock IC. Looks like I have a winter project!

 

Or, it would be quite simple to cover the opening that vents into the airbox. Of course, there'd still be water in the duct, but it's sealed and points down at the front as it follows the line of the bonnet. I don't think water will be a problem unless it's particularly heavy like you describe. And the natural drainage would really help.

cheers,

 

OK, a few photos for the curious. Warning: this is like seeing how they make sausage, not the faint hearted!



I know it's ugly, but when covered with thermal insulation it will look just fine!



and here's proof that it takes a lot to get around the IC and over the clamps:



Anyway, this version 2 of the airbox diverter looks a lot better from the front looking in the scoop. There's a nice smooth curve up and over the clamps and it's about as big in volume as I can get to fit under the bonnet.



I will post diagrams and measurements shortly (actually, when I've done them...)
cheers,

 

Just remember beauty is not necessarily a thing of looks, but a thing of function.

 

Well, Steve, it's just that in the photos it looks like something that fell -off- my MINI and got run over!! Trust me, though, in the end it works just fine, and when installed under the bonnet and covered with insulation, looks all tricky and techo.

 

This looks like a really good idea.. I have been wondering when someone would come up with a good ram intake for the MINI. The only concern I have is rain.

 

That is funny! Actually, yes it does. Form follows function, especially when it's under the hood.
That's all that really matters, is that it works.

 

DrPhilGandini, shouldn't you extend the vertical seperator out the front of the scoop, so that the air path is divided earlier, and the intake won't rob from the IC when it is really sucking down the air?

Also, for the bonnet-butchers out there, wouldn't the logical end solution be to build an enclosure around a "HAI" stubbed right off the TB and put a scoop above it?

 

The splitter is still about 2" in front of the IC, so I'm not too concerned about the division of air twixt right and left. Also, remember that the opening in my scoop is significantly larger than any other scoop, so I'm already getting much more air to the DFIC than before. You can only ram so much air into the IC in any given time interval.

Isn't this what the AGS is, essentially, without the really large scoop?

 

Ram Intake? What's a Ram Intake? Why didn't anyone tell me that the Ram Intake was for sale? Well...all I gotta say is it's about time...I want a Ram Intake! Put me down for one!

Rain? What's rain?

 

Nice job and a lot of hard work . My only questions is about the " unused " air you refer to. In looking at the original DIFC scoop it looks like it is forcing more air thru the intercooler. It appears that the scoop is deisgned to take a larger opening and reduce it in size to increase the velocity and amount of air thru the DFIC ? Perhaps some ofthose involved with the design could chime in on this .Are you robbing some of this air to go to the intake and if so will that lesson the productivity of the intercooler? All and all nice work and keep thinking outside the box as it were.

 

Good question.
I've avoided it for days fearing the "stink eye".

 

Agreed, a good question. A few related thoughts. According to Randy Webb, on his thread about his new airbox and fresh air duct for vertical flow ICs (here on NAM somewhere), there is excess air entering a stock scoop already! I don't know about that...as I haven't seen his ductwork actually installed on a car to see how he gets it to the airbox.
The other point, which you may have missed, is that I have enlarged the size of the opening on my scoop, so that there is quite a lot more air getting to the DFIC that it would appear from simply "taking air away on the RHS." Increasing the speed of the air passing through the DFIC is clearly a good thing to improve TE, but at 60mph, there's a whole lot of air passing through the IC already, ram or no.
I also had a DF scoop before this, as well as my own diverter which took the entire (larger) opening and forced it into the DFIC (see the definitive scoop thread). All I can say is that the current setup -seems- to be producing lower IATs, measured by responsiveness of the engine and general pickup and performance. Unfortunately I dont have thermocouples on my DFIC as I am waiting on M7s "promise" of something for those of us who want a package to measure such things, perhaps.
I have been approached by FlowSource, a vendor here on NAM, to try out a new aFe air filter in my system. I wish I -did- have measuring equipment, as I'd like to see, as they contend, if all filters are actually not made equal. I anticipate way more dirt and dust in my airfilter as a result of my ductwork, so a nice reusable filter that keeps fine dust out is going to be essential.
NO stink eyes around here...
cheers,
