I'm guessing that a good way to tell when your intercooler is reaching it's limits would be an IAT sensor, because typically the stock setup is still good for near-stock applications. Because you basically want the smallest cooler for your power levels to reduce lag.

The only issue I have with this, is if you're running water too fast then it doesn't pick up heat as effectively because it's not spending enough time in the cooler.

High volume fixes all problems, I'm going BIG for my heat exchanger and adding a reservoir, Audi had run an evaporator in their water reservoir off of their ac compressor in rally. I've been toying with the idea, being an HVAC/refrigeration mechanic.

that is a problem of the fluid being used. not the speed of it moving. we are not talking any kind of serious flow here. just constant and consistant. you think the 25 year old toyota pump is up to that?

I just did gauges on mine and I added a temp gauge to the output side of the intercooler to be able to monitor the temp of the coolant. Never liked not be able to tell how hot that really was or able to see if upgrades , constant run , fan , etc made a difference at all ....

I've had the ARC & now have the ST205 WTA ... honestly there is no comparison between the 2 units.

The ARC is an improvement over the stock A2A TMIC, but if you live in a climate where ambient temps get above 90F then it's just as useless as the stock interheater.

I put in some Water Wetter into the ST205 core & it works like a champ. Of course it gets hot too as it sits right over the motor, but I don't notice the heatsoak as badly as the ARC.

So from my experience, I'd put the ARC/Bay Area under the stock 185 A2A, then the ST185 CS WTA.

This is a good reference thread though for those new to the car & looking for OEM I/C mods.

Well just spent a few hours installing this guy.....

It's heavy seem to be very well built, did I waste my time?

A look at the fun density inside the core might add some insight. I have a feeling you will need a fan to help with heatsoak and consider a way to seal it tightly with the air scoop. Running air intake temps will be the best way to know for sure.

Would there be enough space between the TMIC + fan and the hood?

Not much room left, I will be able to use some foam and get a good seal.

Hopefully it's better than stock.
