I have an 2002sti (7). I'm running the standard top mount, with other mods and is in excess of 350bhp.
I do have a charge temp gauge at the throttle body and also measure at maf. Under normal cruise i see ambient temp or 1 or 2 degrees above. When i give it some which is quite often the temp does indeed rise, but to no where near the temps quoted on here,
Under extreme road driving i have never seen more than 10/12 degrees above ambient.
The temps will climb to 50 or 60 if sitting in traffic,But as soon as i move off there down again.
The only time I've seen higher than sixty is after a good hard blat and then parking up for 20mins or so. Directly after a restart there high at throttle body and at maf. Normally there the same. As soon as its started the temps quickly go down to ambient.
If anyones interested I also find when stationary that throttle body temps do indeed climb a little quicker than maf temps. Although they ultimatly reach the same max.
When moving off though throttle body temp go back to ambient at least twice(if not three times) as quick as the maf temp does. I found this on the o/e setup and my current aps cak.

That sounds about right Mel 
standing at idle is a killer for TMIC's but as soon as you get underway, the temps come down quickly.
There is a thread here that gives some interesting detail on tmic temp rise/fall
22B Bulletin Board: thermal dispersant messing around
Just in case anyone considers I have been remiss in not monitoring the effects of high charge temperatures, how about this set up from my race car early last year .......
Temp at throttle body 196 deg C
Designed to use Methanol as a fuel but run on Optimax at 2 bar boost during testing.
Effects on combustion ? Lets just say I no longer worry about using a charge temp gauge
ps, I don't recommend this approach as it did melt the tips off the fuel injectors

Mr F, i added a FMIC and was given advice by coulty, he also said closed deck block(2.3cc) and 20 G turbo with sti v5/6 heads and one of your re maps, this is all for my00 2000 turbo. I'm looking for around same power as him (420 BHP) Anything else i should do??. sorry to hijac thread.

Once our car finally retires from any use what so ever, I want to do something similar.
How much weight does it save to remove all the crap?
Lifting the engine out must be a real doddle now as well...

I have the exact same one Harvey has linked to on the first page. I also got mine from r&b motorsport.
I see you thread on 22b, The 18g is a wicked turbo and no different really in response to the vf i was running. Goes alot better though.

Hi Mel long time no hear, thanks for the reply & do you have a link for R&B motorsport, with ref to the 18g are them power figures correct on your view my scooby as they seem a bit low for that turbo
Edited to add just found the link for R&B motorsport

The third one down is what you want.
Lol. No i havent updated it.
Around 360bhp/340 torque although havent had it on any rollers. The difference is night and day though

The Scoobyclinic/Jap performance article isnt fair anyway by the very right that they swap to a CAI kit when going FMIC.
Why didnt they run the CAI kit with the other 2 coolers? There was nothing to stop them doing so.
A nice doctored article IMO that isnt worth the paper its written on.

Although mine is pretty much like this one harvey posted. Only difference being this one is above the i/c outlet mines next to it

Yes exactly there mate. The one in the pic of harveys also has a take of for boost gauge. Which i dont have as it was already plumed in some where else. When you order you will probably get asked do you want the sensor with a boost gauge take off.

Ian : On a top mount you can put a rag in to catch the swarf and mount it as I have done in the photo which is on the Blue STi 3 Wagon. The sender is threaded and plastic so if you get the hole diameter right it forms a tight fit. I then used Araldyte for additional security.
It would also be possible to mount it in the pipe, TMIC to throttlebody if you sleeved the rubber pipe with an aluminium or stainless steel pipe insert/joiner.
On the WRX Wagon with a Hybrid FMIC I have mounted the sender in the aluminium pipe just before the T.B. Again additional security is provided courtesy of Araldyte.
On the STi 6 Wagon with an APS FMIC, I have put an aluminium joiner inside the silicone pipe just before the TB. I then drilled through the silicone pipe and the joiner to locate the sender and used Araldyte again.
I have probably fitted a dozen or so to other cars and the technique is always a variation of one of these above with extre security from Araldyte.
The only problem is that if I now want to remove the TMIC from the STi 3 Wagon, the sender will have to stay with the TMIC.

You will perhaps observe the current power output of 470bhp which is safely achieved on the std Sti TMIC.
The next stage of 500+bhp upgrades will include a top quality FMIC set up

Yea araldyte for security. I also dont know how Harvey has mounted them on the later sti coolers in the same position as the one shown.(maybe he could advise) As you know from the pic of yours
http://img.photobucket.com/albums/v1...pValveOld1.jpg
The later coolers have the oil breathers running across them. Hence mine is fitted where youve arrowed.

Why did they also not compare theirs against an APS FMIC or Hyperflow FMIC, think i know the reason

Must you use the sti8 scoop with the sti8 intercooler? Only say this as i don't like the big scoops on classics. I have a facelift my99.

Can i use my original scoop with the sti8 i/c or do i need the sti 7/8 one to get the maximum benefit? Do the sti 7/8 undertrays fit the classic scoops and i/c? Or can they be modded?
So many questions!!
Hope someone has the answer(s)

Tony : I don't know what conclusions the WRC team came to regards charge temperatures but like you I know the car performs best on a cold crisp winter's day, noticably so.
Maybe Mike Wood will come along and give us the benefit of his vast knowledge.
I also know that if the temperature measured just before the throttlebody is 20C, by the time the charge gets to the inlet valve or cylinder, it is far higher than 20 deg C.
Retaining the STi 3 TMIC I experimented with STi 3, STi 7 and STi 8 scoops.
The improvement from the STi 7 scoop was disappointing but the improvement from the STi 8 was very noticable. Not enough to solve the problem unfortunately but an improvement. I bought my scoop from David Reed at DRMotorsport and he supplies them to your colour code.
To get the best out of an STi 8 TMIC on another vehicle (Classic?) you need the under tray and scoop. However, whatever the improvement it will not be as stable as the charge temperatures from a capable FMIC.

On my Sti5 I used a DRM V7 scoop, it is just a slightly higher version of the original and not as obvious as the Sti8 scoop. It fits 97-00 cars
Pic here - STi 7 Bonnet Scoop
On the Sti7 I still use the OE scoop at 470bhp without issue. I could probably reach the turbos maximum output of 480bhp with the additional cooling from a FMIC but would pay the price with gearshift lag and compressor surge, probably resulting in a slower car overall.
