Wow, how bad is NAM when people are fighting over vocab.....

 

oooh....loaded question. melikey

 

I'm confused . . .are you talking a light-sourced or heat-sourced furnace?

OK, back on topic everyone.

Can current HDI owners get the RAF portion to update their intake?

 

follow up Q to that will be WMS HDI or DDM DHI?

 

i saw a pic of that gold foil stuff wrapped around the roll cage of a race car before. also solar blankets are very effective at reflecting heat back, somewhere like 80%.

 

"refractory" refers to the high heat property of materials (crucibles, things like that, metals like tungsten, tantalum, inconel, etc.)
"refraction" is the bending of light waves

Wikpedia ain't always the end-all.

that being said, stainless steel is not considered a refractory metal. It does have a low thermal conductivity for a metal, which is probably the feature Randy is espousing

 

I may have espoused incorrectly - I was referring to a term I was using way back at university doing thermal labs. Sorry if it caused confusion, but I think the point was clear. In terms that are as concise as I can say, I used stainless steel because it has a much better tendency of keeping things that are hot on one side from being hot on the other side.

As far as the thermal coatings, there are coatings out there I would use, but the cost is too prohibitive. We are going to offer a riveted thermal blanket barrier as an option.

The unit will work with the scoop for the DFIC, but it will not work (that I am aware of) with the DFIC itself unless used without the RAF - the SportBox will work with any intercooler the same as any of the other aftermarket CAIs.

As for compatibility with the original WMS HDI design, I have built this unit to supercede all CAIs on the market. With some fabrication it could work, but the SportBox has a removable block plate that is used for the RAF.

I would be happy to entertain ideas on a RAF specific logo! It sounds cool.

Keep the questions coming, and let me know if I missed any.

Thanks,
Randy

 

so, a notch out of the side of an HDI and that piece will fit? sweet!!

 

It may - the SportBox has a larger volume, but I believe at that point of the box, the height is the same. I haven't tried it, but I would think it could be done with a little fab - anything can be really .

Hope that helps!

Le Mans and other endurance cars use it.
The frame rails are coated in some instances which when tied to the interior roll cage lead to lower cab temps.
Very cool...

 

the hatch cover of a McLaren F1 is covered in it too

 

a guy at ktr performance swears by that stuff.

 

This is rather confusing.
You wouldn't really have a DFIC scoop without a DFIC.

If the RAF duct for the SportBox(quote from your post on the WMS forum) "utilizes the unused part of the IC scoop on the bonnet". How would this be possible when the DFIC scoop closes off that part of the scoop?

This guy is using a GRS intercooler and is Having good results with this scoop

 

That's cool.
I only said that because most people that have it, got it with the DFIC.

 

No worries, I would of thought the same thing but I know this guy

I really like this Air Box Randy it looks pretty "trick" I am in the market for a new intake. Thank you for keeping us up-dated -- Johan

 

Ah...no. The DFIC is much taller than the stock or other ICs, and the exit horn would interfere with the ram tube.
btw, I must have missed the post, but I don't ever recall seeing TE readings from pre-intake filter, pre-SC, and the usual pre- and post- IC? Do we have any evidence, other than anecdote that a significant lowering of post IC temperatures can be achieved by a (relatively) small lowering of the pre-filter temperature.
Just asking...
cheers,

 

I'm sure once a production ready unit is available, Randy will enlighten us as must as possible. I'm anxious to see numbers from him as well as independent testing. DFIC discussion aside, I'm sure anyone can see how having a horn utilizing direct ram air would be beneficial. This filter would see fresh air from below, the side, and from whatever it will pull from the cowl vent. I guess the bottom line for me is that I can't really imagine any better way to get more air into the box, save cutting a hole in the hood and installing a nice scoop there as well.

 

You are right - the unit would not work with that version of the M7 scoop - again I don't think that is all that bad... There must be more than one version of the "M7" scoop.

Thanks for posting the pic - it helps!

Randy

 

I belive the term we are searching for is

CAUSTICS adj. The enveloping surface formed by light rays reflecting or refracting from a curved surface, especially one with spherical aberration.

Caustics are formed by light that is reflected or transmitted by a number of specular surfaces before interacting with a diffuse surface, or when reflecting off non-Lambertain surfaces. In English, sometimes in the real world, materials can focus light and cast effects, like the highlights at the bottom of a swimming pool or the pattern caused by brushed metal

I deal with reflective/refractive properties alot in 3D doing simulations or just making pretty pictures... and well... almost anything reflective/refractive can cast caustics.... I dunno how this effects an intake.. but... there's a neat new word we can all use to further confuse overly technical conversations

nice intake Randy!

Refractivity referse specifically to an index of refraction, which is a property of waves transmitted through a material. Refraction is in fact a multi-use term, which does apply to metals, but refractivity does not. So educate yourself first, others second. At least try to use the right term.

 

 

You will see measurable and repeatable lowering of IC temps with a drop of 10ºF at the filter.
You will see differences with lesser changes but they will also arguably be within statistical noise levels. 10º is pretty solid.

I've recorded this with temp probes next to the filter and pre and post IC.

For sh**s and grins just turn a can of compressed air upside down(or use a can of circuit cooler) and freeze your filter
The propellent is CO2 so doing this while the car is running isn't a good idea.

 

is the back open on this unit to source air from the window vent?

 

The reflective material on the top of the boot on the Mclaren F1 is gold

 

At $30 per linear foot, I'd be swearing too!!
