I think we should make the rich pay for everything...and in the end, we get nothing

 

damn, i hate you guys at M7! i was doing really good and now i have to save up $150 to sent you.

 

If this wasnt coming from m7 I would think its just one of those silly parts you found find from moss, but if its got that m7 logo on it, i'll drop the cash, keep up the good work

 

Is it just me or are these images confusing?




In the first image there is air flowing up over the top. In reality the radiator support seal closes this off doesn't it?
In the second image this is gone.

I've seen tons of flow models. Honestly though just as a side observation since that isn't what I do but I do work arounds dozens of wind tunnels and did systems support on them for a decade.

The first image indicates no flow through the radiator. That's odd. Would that only be true if pressure on one side were the same as it is on the other?

The flow mapping in the second image doesn't make sense. There are voids in the flow at the lower inlet that would be filled in a normal flow model and since I'm assuming( yea I know ) that red indicates a high pressure area why is there no high pressure indication at the bottom side of the APD where the flow meets an obstruction and makes a 90º turn?

Sorry about the questions. Looks like a nice idea just trying to get a handle on it.

 

alot of japanese cars have used these lips to promote more airflow through the rad.... so this isnt some super new idea.... i am interested to see any aerodynamics person can desciper the airflow though, as any air that can get through the rad is always good in our little cars

 

How do you the test the benefit of this mod? Oil temp? Discuss!!

 

I hear what you are saying about the images. They are a little confusing when you first look at them. As far as the radiator to hood seal, I don't know why it is shown in the first image that the air is flowing over it, and not the second.

Don't be sorry at all, this why we post this stuff, so that we can analyze and discuss it.

I think Will needs to chime in here, maybe he can answer some of your questions.

 

Let's see if I can give some answers. As for flowing up and over, it's not. It's actually flowing around the side, and it looks like it's going over, but the flow lines are in 3D and the image is a sides shot, so it is a little confusing. I'll try to selectively remove the ones that low around the side, or get another shot to make it more clear. I actually sealed that area as close as i could replicate, but i'll double check and make sure. Sorry about that.

The colors are actually velocity, and not pressure, which might help to clear up that bit of confusion. I limited the trace lines to a small section of the opening, a slice if you will. It was just too confusing otherwise.

 

SRTech will have it on his car for the whole MTTS event for everyone to look at. We are getting it from Peter Sunday after the Historics.
See you all on the road.

Yeah, it's all good. Problem is, I knew what it was doing, flowing around the side, and didn't look hard enough at the picture to catch how it would look to someone who hasn't seen the whole data set. I'll revise it tomorrow sp it's more clear.

 

so when will this be avialable again? damn you M7, there goes my lunch money again!

 

Thanks for clearing up some of the confusion.
I'll look forward to your revision.


cmbtmini, it will be available in about 2 to 3 weeks.

 

Material choice is always an issue, and kind of a damn if do/don't problem.
The reason for my choice of material is simple; it's what sells and most people Prefer.


We will not make it in metal or fiberglass, as the part is fairly complex to make and the construction is vacuum bag/autoclave for perfect surface finish
and exact tolerances.

I hear you, besides I love carbon fiber. Guess I'll need to order one soon.

 

Thanks Will.

 

Any actual numbers for this thing? How much more efficient does it make the radiator? The coolant temperature is how much lower at speed? I'm sure it's good for at least 5 hp.

 

Is this not basically just a "radiator cooling plate or shroud" I believe is what they say in the import industry..?? If so why not aluminum. Seems to be the material of choice for most. I have seen designs a lot more "complex" than the Mini's made using metal (Nissan Silvia for example).

Either way it looks nice Peter. I like these little "extras" you guys seem to keep popping out on a regular. Way to stay innovative!

 

You ain't seen nothin yet

 

M7,

Has this diverter actually been test fit on a MCSa? The reason I ask is that it appears from your photo that the horizontal surface of your diverter is in line with the horizontal surface of the front bumber cover. Inspection of my car (automatic) reveals that the transmission fluid cooling exchanger is higher (approx. 1/2 inch) than the horizontal surface of the bumper cover. So, unless your diverter has a concave underside, allowing the additional room needed for this unit, it will not fit. Is this a fair assumption?

Much thanks!

 

I honestly don't know, as we see very few automatics. I will check one out when we arrive in Monterey for the Historics...

Will or Peter,

What was the inlet flow rate on those plots? Have you modeled this at different rates?

Any thoughts on applying this design to your mesh upper grills with louvers attached in order to direct all incoming air to the radiator?

Thanks, paul

 

The "car" is "traveling" at 65 MPH. I've run it at other speeds, too, and the behavior is approximately the same.

That's an interesting idea about changing the grill. Let me stew on it for a bit. I'll have new pictures up tonight or tomorrow.

 

this is awesome and the price is greatg too!

I will place M7 product on my MINI before any other.

 

Sorry for the delay, guys, but I appreciate the patience. Last night I took the data set and adjusted the section of the trace lines. The lines that appeared to be going up and over the radiator actually were going around the outside of the hood. The 2D representation made it look like it was still inside the engine bay, and I am sorry for the confusion. So basically, I tightened up the tolerances for where the lines could be displayed, and it's much more clear, I think. Again, this is a velocity map.

 

Hi Will,

what are the practical benefits of this mod?
