Drivetrain M7's Direct Flow Intercooler 2 (DFIC2) System" - Technical and Detailed Opinions
Wouldn't normally I would think, but it was one of the reasons that Mark downgraded my membership here.
As far as nuts goes? Because that forum shows 'intent' to disrupt NAM, it's members and vendors. I don't know, ... your a member there, ... you don't see the connection?
Did I really need to answer this?
I saw that you posted it here, but then edited it to add my quote, ... so I gather you were directing the question to me.

Marwan, do you have anything in place to deal with all the sand clogging up the intake, radiator and IC (and everything else 
) ?
We lived in Jeddah for 4 years (man, I am jonesing big time for a schwarma ) and it seemed like everyone I knew lost at least one car to overheating or from sand gunking up the works.
You might want to consider an IC sprayer that feeds from the front and rear washer tanks. It's not like wipers get a lot of use over there
Good luck with whatever you decide!

You rock man! Let's ask Peter from M7. I hope he answers.
To get into town, we had to drive by the airport cement plant, which dumped another ton or so of dust into the intake 
Of course, it was NOTHING compared to living in Libya. A storm off the desert there would strip the paint from a car in seconds
Good luck with your mods! Any part that works there to keep temps down definitely qualifies as being stress tested
Ha...You'll see me on a pilgrimage to Mecca* before Peter responds with real actual hard data.
*Won't that give my Rabbi a surprise.

Well, let's see. Peter is following and reading this thread. I hope he answers as soon as possible. I somehow believe in Jan as my car mod project manager. But this does not mean I'm going to forget about M7. I'm considering the SC pully, Aerojel and the air deverter.
2 out of 3 are excellent products. The jury is still out on the Aerojel product over the header. It does reduce the temps on the coolant and power steering bottles but is it at the expense of higher temps elsewhere and improper under bonnet airflow. Is the air coming off the IC supposed to flow over the engine and out under the car? The Aerogel under the DFIC does seem to work in keeping heat off the bottom of the DFIC and M7 does sell an exit scoop for the DFIC that can be grafted into the bonnet. Should all these products be used together for best results? If so thats pretty hefty hit on the wallet. Some data showing all this is or is not required for gains would go a long way in clearing the air.
For the mods you have listed already: Pulley, open up the JCW intake by removing the flap, pulling the plug and adding a more free flowing air filter element (ITG, K&N, Amsoil or AFE), exhaust & RMW tune. If you want to go bigger then go with a header & improved head. The important thing is to plan the path you want to take in order to maximize the cash you're spending.
+1 for damm SC pulley
Dude if you have not at least gotten the SC pulley what are you waiting for, are still debating about your Intercooler? I think that one (IC) you can wait on. But please, please, please get SC pulley now M7, Alta, Helix, Craven, hell Paolo Uber I don't care just get one. And tell us what you thought. Buy a used one I think I seen one on the marketplace.

Peter is a friend but two words would stop all of this.....
"spec sheet"
I work in thre Pro audio/ AV / commercial sound markets and EVERY product has a data sheet......
Realize that acquiring data cost money that will be passed on to the consumer

Some Data
This is from the V1 DFIC, and shows the basic issue with that one, pressure drop.
While this is only half the issue, it also causes the Eaton to push against a higher pressure, which further degrades efficiency. Three things can reduce the pressure drop:

While this is only half the issue, it also causes the Eaton to push against a higher pressure, which further degrades efficiency. Three things can reduce the pressure drop:
- Increase the cross section of the internal flow paths.
- Decrease the internal turbulator (fin) density.
- Do something about the flat bar geometry so the air has an easier time getting into the flow channels.

but what it doesnt' show reguardless of pressure drop is the efficiency and or HP gain (or given back) by said efficiency....
and yes.. you can test intercoolers on a dyno... cuase if they work... they work....

That's why I said....
that it's only half the issue.
For what it's worth, with a G-Tech the DFIC made 7 hp over stock in 2nd gear at red-line. For a bit less than a grand, that's about $100 a hp, or a very steep price indeed.
a 15% pulley does about 15 HP at red-line, and at $400 installed is a much better bang for the buck. By a factor of 4.
That's why I say that ICs are far down the list of mods to add to cars. Personally, now I'd do the pulley and then save $ and just go with a good head.
