Excellent. So then logically one could assume that the higher the boost level in the manifold, the less restrictive the intercooler is. That would then explain that the M7 DFIC felt the most responsive - the peak boost level is consistently higher on each of the runs with the M7 intercooler.
I think it is safe to say that the M7 probably makes the most power due to the additional 1 PSI it ran over its competitors while still providing reasonable Delta-Ts.

Didn't the DFIC have significant pressure drop during Dr. O's testing?
Kudos and thanks to you guys for this research and sharing the results, especially for the clueless types like me who have to rely on other's ingenuity.

thanks so much for providing the mini community with these real life tests. the fact that you don't work for any of these companies adds a nice amount of credibility to the info (no smoke and mirrors).
it's great to see the numbers, but i want to know if there was any difference between these intercoolers for the drivers seat. it seems often that we spend lots of money on parts that aren't easily percieved from just sitting behind the wheel (ie intake) could you feel any differences between the different intercoolers and their designs

You know we did feel differences between most of them. When you have five different intercoolers on in one day you can feel differences between them. Here's my seat of the pants take on the IC's
-The M7 DFICV2 - always feels snappy and quick on the throttle to me, quick response and pulls hard. This is the main reason its on my car. I like the way it "feels" compared to the others. It does get sluggish when its hot but it cools down fast enough.
-The Stock and the GRS felt really similar. They both felt more smooth than "hard pullers" Little more soft in the response but still pleasantly responsive.
-Forge -this intercooler felt real sluggish under wot. It was the one that we felt the worst about when it came to seat of the pants feel. In fact, when I was listening to the recordings we made, I heard us both make the comment of how sluggish the car felt compared to the others.
-Alta - You know, this intercooler didn't feel that bad on the first run and I remember commenting on it. By the third and especially during the heatsoaked run we could tell a difference. The car didn't want to react to the throttle.

Makes sense and would be my thoughts on it as well. Makes you wonder at what point does the higher heat and boost level cancel each other out. Or does it at all?

Well you could use the ideal gas law to calculate mass if you want to and then determine which provides the largest mass of air. Of course that does not take into account the difference in detonation resistance as a result of lower temperature.
How does the DFIC vs. stock data compare with M7's R&D comparison data?
If they did the same tests I did (Freeway onramps, 3-4 gear blasts) I'm sure it would be real similar. I'm not sure they have done any cooling comparisons, any of the companies for that matter.
Seems like I see dyno data and power curves but not real world cooling capability.
The cool thing about the way we tested, is that it takes into account real world airflow, scoop design and different product features like being sold as a complete system. I'm referencing the GRS for example comes with diverters and custom hood liner designed as a system. Same with the M7, areo gel blanket, hoodscoop and diverter. Stock even comes with diverters and ways to channel the air.
I think this type of test will show things a little differently than blowing a fan on the intercoolers in a shop

The GRS intercooler cooled the best , better than stock by almost 20 degrees.
I think that there is a pressure drop with the GRS that we weren't able to accurately record.
Matt did pressure testing on the GRS and it showed LESS OF PRESSURE drop than stock. The Forge should test out similar.
Where was your boost gauge tapped ? What scale is your boost gauge?
As much work as it was, it was more fun than work. I would certainly do more testing if the opportunity came along
Let me know if you do. I have a modified Forge which I would love to see if the modifications enhance performance. I also have a DFIC ver1 you could play with.
Overall good job .
Testing like this - done by a NAMer w/ no agenda for NAM is the best. A refreshing thread from the dribble of late.

The only thing we had to measure boost was a scanguage II. The only accurate boost readings we could pull of it were max pressures. It was pulling them from the MAP sensor in the intake manifold.

Jan...check Longboard's post#63....he was able to quote Nitro before it was edited it showing what was originally intended to be posted. "Cause your are a vendor so that makes it a little biased" Oh and you can't forget the classic signature of the POPCORN x2. Do you still wonder why it was edited?? HeHeHe

I would love to test the GP, new version GRS and any other "updated" air to air versions out there.
I would also like to test the Laminova, Gintani, madness and GRS water to airs. Of course testing water to air set ups would be a major undertaking. If I remember correctly installation involves some bumper trimming to get the radiators to fit? Hell, who knows, might be worth the trimming, if I find they work waaaay better I would probably buy one!
