i checked and the thermostat runs at 170 in the turbo legacy... its great for cold days. it warms up the engine quicker and when im running hard, or fast, it stays there too! which means when i start raising the boost and the air gets hotter, it will always cool it back down to 170.. if not ill put it on different lines, but untill i see any problems with the intake temps, or the water temps, its good the way it is...

Ouch... the objective is to get the intake charge below 100 degC... unless
you live in freezing conditions and the intake charge is condensing and
puddling down the sides of your intake manifold!

Never heard of a situation where an engine temperature is colder than
ambient.

Just by doing some quick testing a while back on my Legacy Turbo,
with no intercooler the intake temps at WOT in 4th gear reached
around 130 degrees at roughly 9.5-10psi, with the intercooler, the
temps dipped down into the low 90's, all measured right at the
throttle body on a 55f degree day.

It seems that at the moment you are actually heating the air more
then if you had no intercooler at all. Hot engine coolant is the
reason that many people, especially the Mitsubishi crowd, bypass the
coolant line that goes through the throttle body to help warm the air
on cold days, because it's doing just that, warming the air.

I know you mentioned that it's for when you start adding boost, but
even 170 degrees sounds hot, maybe not though?

woah, no no... hehe, i was talking about water temps in the coolant... i dont
know what eth intake temps are as i have no gauge there, but i would like to
really know, how would this be possable...

Yes mike, we know, but the temperature of the water will heat the
temperature of the air around it, that is how you have heat in your
car.

At the moment, I have whatever ambient temperature is cooling my
intake air temps, you have 170 degrees( maybe not exactly 170, but's
it's definately hotter then the ambient temp!) of heated air from the
coolant cooling( or in this case, heating) your intake air temp.

As for a temp guage, I just picked up a small electronic thermometer
with an outside sensor( sensor attached to a long wire ) at
Radioshack. Not very fast reacting, but it does what I want it to do.

170 degrees .......this train of thought has completly lost me.
eg. take a wrx with an air/air intercooler.
just imagine how it innefficient it would be if the outside ambiant air temp
was constantly 170 degrees. i do not know of anyone who wants their
intercooler to run hotter ???????????
