And the Alta was a prototype, this is much closer to the released product.
Look in Alta's thread, and they too are going ahead with the unit.
Alta's prototype didn't have as good thermal efficiency as the stock, but had lower pressure drop, and did create more charge denesity and power.
The testing was done with a G-Tech accelerometer, not a dyno, but did get real-world air flow conditions.
Pressure drops were measured vs RPM with no load.
I'm not saying this as an edorsment or a slam to Alta's unit, just correcting some errors posted earlier in the thread.
With all that, the M7 unit looks nice, I saw it at AMVIV. When they have an extra unit and I have all my diagnostics back, I'll put it through the paces and let people know what I find.

So patents of the M7 unit seem ok with the Alta unit ?
I just called Randy to see how it was going with the DFIC, to my surprise he and Peter were actually in his car getting some numbers! He was reading them off as he was talking to me and the IC outlet temp just kept dropping!
Unreal, to say the least. Looking like I will scraping up some cash for this one!

I sure hope that they were driving through some cooler air
64 degrees out with 70 ambient (real jelous here, as it's mid 40s and raining outside) would be some serious mojo!

Sorry I had to edit post #53 and remove the numbers.
I misunderstood Randy when I asked if I could post the numbers he was telling me.

However, the numbers are consistant from what I've experienced with IAT data collecting...If the standard Ram Intake can bring the IAT of Alta IC to within 15F of ambient (regardless whether it's 10F or 80F ambient), then it's not a stretch to conceive that a DFIC with much less air flow restriction (as the air flow is not taking two 90 degree turns before exiting) and higher velocity combined with an asymetric Ram Intake that incorporates roughtly double the apature area could drop the temperater another 10F...right about what they were reading

I just got the real numbers and you wouldn't believe me if I told you
It appears too low to be physically posible but numbers don't lie. However we have some theories as to what is happening...Dream come true is all I can say for now

I do have a theory or two to test!
So when will we see some figures and numbers for this new intercooler?! I'm extremely anxious now...Should we go ahead and spend $900 on this, or wait another year and hope someone designs an efficient front mount?

Thank you all for being patient......
The R&D core has been tested many times since it's inception, but the scoop and diverter was questionable at best. As we did add two test ports on our
patented intercooler design, numbers where only a test instrument away
and honestly the numbers where very, very promissing indeed.
As the hood scoop was received last Tuesday and the new diverter Thursday
morning, no time for testing was available last week (AMVIV Thurs-Sunday).
Fast forward to this afternoon and all I can say is......I'm stunned and
very, very excited. I will give one set of numbers and I hope you understand
why I will hold back some of the readings as Will is doing some CFD Sim's
to figure out what happened.

. Peter, ol' buddy ol' pal, you may just need to throw a release party at the Dragon for this . You know that Team M7 will be out, in full force!
