not just the best....but the best in the MINI universe!!!

 

Im thinking that that might have been said in jest but if its what you want to beleive I am not going to stop you

Believe me I'm not saying it's a bad product. I believe it's very well done and innovative on the MINI platform.

I'll gladly wait for more numbers since I've made it a bit obvious that I'm not quite sure about 114% efficiency.
Shutting up now

 

the laws of physics don't change...our understanding of them does - BB 06

 

I'll believe it until its proven wrong. after all this is America..innocent until proven guilty.

 

Holy Quantum theory Batman!!!

 

Based on the numbers posted:

Stock IC - 54% reduction in temperature
GRS IC - 58% reduction
M7 IC (original, but in error) - 65% reduction
M7 IC (corrected) - 48% reduction

Now the new IC doesn't look so good. The efficiency number (114%) that was referenced for the M7 IC (corrected) is meaningless, because it is impossible, even in the Mini universe. "Obehave" expressed it quite well.

Obviously, testing conditions between the stock & GRS were different from the M7. Before anyone starts or continues to use extreme hyperbolic phrases in describing this new product, it would be prudent to see meaningful data, i.e., data obtained under appropriately controlled conditions. I believe that Matt will be doing this...

 

If you think 114% efficiency is impossible, then you don't understand the laws of physics, or perhaps you don't understand what's going on. Either way, that's a mighty bold statement from you. I believe if you think about it for a bit, you'll be able to come up with the answer that fits. Whether it's right or not, well, that's another question that can only be answered with more tests and more data.

So let's just accept at this point that so far, data shows that the intercooler works and works well. I believe in it, certainly. If you don't, well, don't buy one. But we aren't going to stop with a few tests and expect that everyone will jump at it. That's why Matt is going to test it, with the same methods as his previous tests, and you can go from there.

 

Thanks for the note, and you are correct that one can indeed get efficiencies greater than 100%. I shouldn't have used the word "impossible"; however, the basic content of my post still stands. We both agree that appropriate testing is indeed in order...

 

Poo all gone now

And thanks Will

 

That's NOT how you measure IC efficiency. Read my post on the previous page and learn the real way.

Do you follow the weather? Are you familiar with how temperature is reported- specifically, "temperature" and "wind chill factor?" You know how wind chill factor is cooler than "temperature?" The IC uses wind to cool. It operates by wind chill. In so doing, it can achieve more than "100%" efficiency.

If you don't believe me, think of it this way [to be completely transparent, this is an educated hypothesis]:
Air flows through the IC's fins at, say, 50 mph at 70 mph. Charge flows through the IC at, say, 100 mph. IF the volume of air passing through the fins [speed of air * cross-sectional area of aperture] is greater than the volume of air passing through the charge tubes, you can achieve greater than 100% efficiency, since each unit air passing the fins can extract "x" amount of energy [heat] before it achieves an equilibrium with the charge air. The IC's front section area is greater than that of the pre-IC boot, judging from the photos provided. Therefore, it is possible that that is what is happening here.

If anyone would like to have further detail regarding my "back of the envelope" calculations, pm me.

 

I honestly don't think that that comment was directed at you, man. I can see how you read that, but seriously- don't be offended. We are all entitled to our own opinions. In the end, the truth always prevails. You're right to be skeptical, and it is the onus of a vendor to earn your money. But, again, I think this is a misunderstanding. I've only ever had extremely positive experiences with M7 when personally dealing with them. If I were you, I'd take the opportunity to call them up and ask them your question in person. I know that they will be more than happy to explain whatever it is that they know. Either way, have a great one!

 

Well, but I wasn't talking to/about you at all...

see:

And I wasn't trying to pick a fight or start a pissing contest at all. I'll be happy to discuss with you how the efficiency can be over 100% over PM/email, but my main point was that there's not enough data to draw such thick lines yet, and more is on the way. That's it. I'm sorry that it came off like I was attacking you, I really wasn't.

 

oooooooook....open door wide....ahhhh....nice fresh breeeeeeeeeze

 

I'm exposed........ I stand by the fact that neither the Alta nor GRS allow for air to escape/flow......nice heat sink.

How does the car feel....Peter said that Randy says it feels punchier with more low end and that the recovery is very fast..(I assume while moving)

 

Group hug.........

 

awwwwwwww!

 

Feelings I am all about that We have a well known road in my area . I have been up it at least 300 times and pretty much know each stone, tree, branch and crack from top to bottom. Going up hill it is a constant climb with a variety of curves both with one almost 90% turn. Back in my stock mini days it was mostly a second gear climb with some touches of third. After about 2 years of development on the car and myself i was able to take most of it in high in third with a drop to second at the tight 90. With the new IC I made two runs in mid 4th with a drop down to 3rd for the tight one. Numbers ? I don't need no stinking numbers the damn thing works

That's all that really matters, when you think about it.

 

I won't say which mods I bought by "numbers" that have sucked (read disappointed)

I like my testing method.....which by the way has been painstakingly developed after spending lots of hours and $s on other less imperical methods............ pedal down.....uh,.... go fast.....pedal down with new mod....uh,,..... go faster..... mod GOOD.....

 

Definitely sounds like a good plan to me

 

^^My kind of logic... The butt Dyno is usually enough for me.

Can someone explain to me how the IC achieves outlet temps LOWER than ambient?? I know physics (I have a BS in it) but this is puzzling for an air-to-air IC. I'm not getting it at all

 

I think it is "general" rather than "special".

 

Either I'm REALLY tired, or my brain cells are dying off at an insanely quick rate. I have no idea what you're talking about. lol

Unless you're talking about just gen. phys vs. special phys(quantum theory etc), but that makes no sense...ARG! :impatient
