Intercooler top mount or frontmount

We've been out with the car all day and I've been monitoring my thermocouple gauge and this is what I found.
In normal driving conditions ACT's run 2-3deg above ambient which here today was 21c. In queing traffic at lights, stop start driving, town stuff, ACT's read at 33-35 but no higher with the engine running and come down reasonably quickly on the open road. Two stops for 5 minutes each with the engine switched off, temps climbed to 48c but appeared to settle there. Once the engine started and before moving, the temps dropped quite quickly to mid 30's.
A stop for 30 minutes, on return to the car, temps were reading at 65c. At that point I would say the top mount was well heat soaked because the heat would be in the core and it took some time to shift.

See this is where a cai helps but when your need for air overcomes the available sizing for a cai you have to resort to an induction kit which is sucking in hot engine bay temps. I will conduct a wee experiment with a piece of 4" piping to the outside of the engine bay and let one of the cars tick over for a while and report back with the findings.

From a WRX TMIC you would want to upgrade to a STI TMIC or an aftermarket TMIC.
My APS TMIC made 386bhp on a 400bhp turbo (on a Blob STi). Converting to FMIC cost me some spool and only won me 15 bhp, finally producing 401bhp.
For a WRX, grab a bigger TMIC and hang on to that until you want to shoot for a number beyond 350bhp.

I'm running a WRX Bug wagon with 380+ using a Grimmspeed TMIC and an SC38.
No real issues apparent but then we don't have traffic lights here in mid-Wales.
As well as the mods mentioned above you'll need a revised suspension setup to get that power down.
Assuming yours is a saloon, you'd probably be best off doing what The Trooper said and starting with an STi though.

I'm also running a bigger Process West TMIC on 380bhp with more to come with no issues at all....

Nobody is grasping the concept here a TMIC is reasonably efficient in the right context its when it is taken out of its ideal environment things start to get messy. When stuck in traffic etc etc it turns into an interheater due to heat soak. If the vehicle is then abused from a standstill problems arise with ACT which can and do cause dire consequences. A CAI can help the situation but doesn't cure it. A FMIC near enough eliminates the problem but still suffers to a degree due to pipework. As a safety precaution a FMIC is a winner all the time.

how many cars with top mounts have induction kit's in the engine bay? best advice has always been CAIK with a top mount, even the standard set up pulls air from the outside.
Front mount you get away with a cone under the bonnet with hopefully a cold feed up on to it.

But would the ecu chance settings if there is heatsoak.
I cant inmesion it would be harmful for the engine if there is a couple of seconds heatsoak I would think the ecu will adjust the power or somting.

The turbo produces a lot of heat at full boost and combined with an heat soaked intercooler could cause a problem.

Inner wing induction kit turbo blanket and wrapping up and down pipe the way to go with good TMIC ,,, no heat soak if any with Process west... I'd say the summers down under are a lot hotter than the UK but these intercoolers out sell hyperflow TMIC there....

I wouldn't rely upon it. If the intercooler had just got a bit warm from queing, slow moving traffic etc, I wouldn't have thought that a problem. If the car had been stood for 20-30 mins with engine up to full temp, then the top mount would be hot and to boot it from there, for me, would be asking for trouble.

Just finished experiment. Bonnet shut engine running for half an hour at tick over from cold and its windy ish 77c. Bonnet open tick over for another 20 mins dropped to 43c. Shut bonnet went for a drive on boost 23 ish. Off boost sucking in hot engine bay heat 32/34c. Went back to yard air filter off pipe fitted bonnet shut 4" pipe out through headlight hole 36c at tick over for about 10 mins.
