I think you have misunderstood me. Again you try and use a facade of diplomacy,,. throughout this thread you argue that sti newage TMIC's are efficient but in the thread you have linked me to you make a statement that at high speeds they are inefficient. why would they be inefficient at high speed? you conflict yourself

Depending on the model of the car they are fitted to, the air pressure in that area of the bonnet can make them ineffective at speed as the scoop entrance is in an area of low static pressure. Bug eye in particular is prone to this. The noddy scoop on the blob eye was designed to try and overcome this inefficiency. The whole hawkeye front end is better shaped to reduce this (hence the smaller scoop)
So..
The cooler doesnt become inefficient at speed but the shape of some models can make it see less airflow.

Bait away, no hard feelings. 
The article doesn't test a STi8 TMIC anyhow.
I don't think there was ever any doubt that if you are into dyno queening, then a FMIC is the correct choice.
However, if you're interested in having a quick, responsive, moderately tuned car on the other hand...
Never been interested in dyno figures myself, but would rather the car go quickly.
2.35ltr build underway which will be using one of our FMICs

Hmmmmmmm
So I am going to fit a charge temp sensor. Fit my 800cc and start praying on my STi TMIC!!!
Should be interesting how much the TMIC will take and at what point it becomes a liability.
Running 402bhp 360lbft on current spec.
D'oh!!

my guess is you'd be nearer 430 with a front mount and decent map at your current spec anyway, depending on the size of your current injectors of course. but you will be loosing power due to the top mount

Maybe the TMIC is holding me back mate but as you know you won't know until you try.D'oh!!
Hence (without going off topic to much) why I'll get JGM to map my cars time and time again. I've used two other well known mappers. JGM gave me feedback and advice where as the other two I felt as though It was a case of a quick buck once the job was done. I asked one of them for advice and he strugged and asked for the next car on the rollers!! Nice.
Sorry back to the topic.
Just tempted to see what the TMIC will take on my current spec. I could come on here in 6 months and say "good night engine" or "Still running sound as a pound" who knows.

Steve - I'm running 415bhp/380lb/ft on a TMIC fitted 03STI. Absolute instant throttle response and a real hoot to drive. I don't track the car BUT the engine's done over 50,000 miles on that spec and still runs as sweet as a nut. Providing the car is well maintained, mapped correctly and not caned mercilessly, you'll have nothing to worry about despite some of the scare stories on here. And from what I hear, JGM is a superb mapper. I'm going for a built 2.1 next year and plan to run over 2 bar keeping the 321H for amazing spool and midrange punch. We'll be looking at around 430bhp and similar number of torques - I fully intend keeping my TMIC
what spec dude? Purely Out of interest.

With the 800cc maybe I am being a little optomistic with a power in my head of around 440bhp and aronnd 390/400 lbft on V-Power and 100mls of NF? Who knows.
The point you made of looking after the car is so true. Fluids etcs always checked and so on.
From March my car will be used as an everyday car again (misses goes back to work) and I want a map safe enough with the spec etc. Now and then the car gets to make the most of her legs but it would be nice knowing you have it.

Maybe I'm mad maybe I'm just a fool.
If you want to sell me Hybrid GT2 FMIC for peanuts as a "test and see" let me know Harvey.

It's not just about the dyno figures Steve, so don't get sucked in by that.
The GT2 will not fit your model anyhow, although there is a Hybrid kit available for your model (just not as good as the GC8 kit).
Speak to Andy.F about running a MD321T, he chose to keep the STi TMIC
Turbo spec to be finalised. Likely a rotated GT30 variant for a target of 10 second 1/4mile times in a everyday car.

Although it is fair to say that 10bhp gain would mean more lag? If so 10bhp extra isn't the be all and end all. (depends on the map i guess)

Before Harvey gets to you; Not a chance of MORE LAG for 10-20 hp
50 hp maybe a tad more delay. But 321 series are generally not laggy turbos anyway, their strong point is spool and pick up.

I'm not talking about turbo size and when it spools up - talking about reduced throttle response when already on song

Don't understand this David. Surely the additional volume of air to be compressed remains the same when switching to a FMIC regardless of potential power gain? I'm not talking about turbo size and when it spools up - talking about reduced throttle response when already on song
I'm not talking about turbo size and when it spools up - talking about reduced throttle response when already on songthere is little to no change in responce. yes there is some, but you need sensor to detect its that small let alone feel any difference. any additional responce delay is normaly down to poor setup.

I've had the 400bhp for almost a year and my car is running like clock work engine wise so think sod it.
Up the game a little.
I didn't see prior to posting that the GT2 won't fit. But as you say will keep the TMIC anyway matey.
Cheers
Steve
