Ah yes my friend
I just installed these goodies yesterday! Very very excited about them
The car pulls like a sonofa motherless goat!
It seems that my Invidia exhaust has a blown resonator and possibly mufflers. The car sounds like a raspy trombone playing 757 when I rev it. I called Jan and asked him "does this sound normal" then put the phone down and revved it. When I picked the phone back up all I heard was laughter on the other end! Seriously, the car is so loud right now I'm surprised you haven't heard a distant "trombone" tone when you go outside
I new it has gotten louder since I bought it, adding these better flowing parts has just made me very very aware that the exhaust is in need of some serious help

You learn to read the depth of the laughter.Have fun, don't get it trouble. Seems like I have a homing beacon on my car right now.
Jan - maybe I am reading the wrong thing but my temps read usually about 7-10 degrees above ambient whenever I'm driving around town. On the highway I may be as low as only 5 degrees different.
Scangauge gives me the readings.
I'm guessing that's not too bad.

Give him a break. No one else is donating their car/time /money for this testing. If you want to buy a W2A and give it to Intense for a few weeks during his next testing schedule I'm sure he'd be happy to test it.
I wish I saw temps like that... I'm running stock IC and 15%.... just cruising on the highway I typically see about 15 degrees above ambient (comparing the scangauge intake temp to the MINI thermometer) - when around town I commonly see 20 degrees above ambient. Would love to know why mine are significantly higher than yours... 

Blimey, don't think yours are higher I think Paul's are just reading lower.
The only M45 charged car to be that was 2.0L stroker with 15% pulley
the temps are so low because the max boost on it is around 10psi

Anyway, just to let everyone know what's up with me and the future possibility of more testing. I was laid off my job of 8 years a couple weeks ago. I have been scrambling trying to find work and exploring a few "work for myself" ideas. Its been a real trying time and it's far from over. Intercooler testing and most other things I do "for fun" have been put on hold for now.
I'm just hoping that I will be able to keep my things home, cars, assets. Its time like these when you realize how important family and friends are.
I'll tell you one person that has been a friend to me in a time of need. Mr. Jan Brueggaman, thanks for everything Jan. Thanks for your understanding, help and patients with me in a time of need. I really appreciate you and wanted to publicly thank you

BTW - I'm LOVING the cam, Jan...
wait til the header goes on and a reflash
thanks Intense.... it didn't need to be made public
but I do get a chuckle out of the raspy trombone

Anything less than 20F approach is good!
Here's a photo (made with my iPhone--aargh) just as I came off the freeway this morning, hence the low revs. I had to wait until I was on the off-ramp to get the snap. I was running 70+mph just before this.

The lower gauge reads airbox temp, above it the ScanGaugeII. A 10F approach is pretty common but I have done everything to lower it--probably to the exclusion of other objectives!

I also need to get a photo of what it looks like at 7000rpm. Maybe in a couple of weeks in Dallas...
The bottom line is top mount IC's are not your friend on the MINI. Unless you are above 100mph(adequate air flow) they are cookers. There are easier ways run near ambient IAT under load.
And by the way, the OBD IAT reading is not accurate, it can be off 30-40F or more at various times, even off 20F during transients at cruise.
P.S. Hang in there Intense, good luck, I'm sure you will land on your feet.

Given that the range of IATs falls within 20-280F (and I'm being very generous here), the errors you claim are very large. Are these instruments that poorly designed and calibrated? What is the accuracy? Does the manufacturer have a spec sheet?
Given my obsession with intake temperatures, I'm very interested in learning more about these issues. How would I independently measure IATs in the Mini?
Thanks for any information you can provide.
now that people are better informed............we have gobs of data to spring on the community for even more performance
Interesting. Any evidence to support this assertion? I believe it's your responsibility to provide it in this case, unless we are using political debating rules, then claims are taken are face value, regardless.

Big Howe is right, I have seen the logs and the equipment is top notch
I think people will be shocked when all of the data is presented
Doc Phil,
It has to do with the time-delay/averaging of the T-MAP. I have a type K tc(1/16" sheath, exposed junction) drilled right into the manifold next to the T-MAP, in addition to before and after the IC. After 30 seconds of cruising they will match, after that all bets are off.
I believe Dr.O has the model/specs of the T-MAP. If I remember right, he said something about 10-second averaging on the temp side, which is an eternity in this environment.
Once I finish this next round of tests, I will post data.

Hi Intense, very sorry to hear about your job loss! I can only sympathise with your situation and hope that you find a good means of generating income very soon.You did stunning work here with the IC testing and we would all like to see this continuing. All the best of luck!!
Next time you have a T-Map out...
take a look at it. The Tc junction is encapsulated in epoxy or something. This is why it's so slow. I did a bunch of research on automotive temp sensors, and thier specs are appalling. Now some of this can be corrected with good software, but the time constent in them is 10-20 sec depending on the manufacturer. There are several companies that make pretty much the same sensors.
One has to wonder what would happen if one were to dissolve off the encapsulation! Maybe it would be much faster but just not last as long? Any one with some acetone and some time on thier hands?
I think the design is for robustness, but the fact that the pressure side has ~20 millisecond time constant and the temp is about 1000x slower doesn't bode well for speed density systems. Maybe this is why the R56 has to have a MAF sensor to meet emissions....

So is there just one maker of water to air intercoolers? Does anyone make a front mount? How about a front mount W2A? And would the money for such a creature be justified or would it be better spent on the likes of a Rotrex? Seems like the improvements in airflow made by the head, cam, CAI, header, cat-back and so on really have the stock SC out of its map.
