Default Which gauge to use for IC temp?

Does anyone know what type of gauge would be good to monitor the temperature of the intercooler? And what type of sensor would be needed?

Autometer make a intake temp gauge that comes with a temp probe. I am running the duel probe setup (before and after the ic), and they work really good.

Omori also makes one. J-Spec Tuning is one place that carries them.

Well, hopefully the temperature is lower after the intercooler otherwise the intercooler isn't doing anything...

According to the 5th page of this very nice document from Subaru, http://www.endwrench.com/current/sum...XTurboTech.pdf:
Quote:
The intercooler reduces the temperature of the intake air from 248-266 F (120-130 C) down to 158-176 F (70-80 C) under normal operating conditions.
Another interesting tidbit from that document can be found on the 3rd page:
Quote:
Rotational speeds of the turbine are in the range of 20,000 rev/min. at idle, to 150,000-200,000 rev/min. at full power. These very high operating speeds and temperatures make lubrication and cooling of the center shaft bearings of prime importance.

I am running a stg2.5 (tbe, uppipe, samco hoses, ported tb and intercooler, stock turbo), and at about 16-17psi the outlet of the turbo is 300 degrees, and the outlet temp of the intercooler is usually right around ambient temps. I did a couple of track days so I would be at extended boost runs, and my after ic temps never went over 110 or so. I am runnig a STI scoop and one of my scoop splitters. I have a thread awhile ago called "intake air temps" that had some pics and so good info. I was going to do some updates, but I got so blasted I figured screw it, everyone can get thier own info or contact me personally. I can tell ya this much, I will NEVER run a short ram in my car, fmic or not. I think my intake temps went up about 20 degree pre-ic and 5-10 post-ic just by putting on a short ram.

Russ, confusing answer to a simple question. What was the typical difference in the tempurature readings between the guage before the intercooler and the gauge after the intercooler?

e.g.
Gauge Before IC = 200
Gauge After IC = 100
Difference = 100

300-110=190

And Russ, your reply didn't seem confusing at all...but I understand about getting blasted when trying to help sure lowers the interest of trying to do so.

You're right. Sorry. I guess I was keying on 'before' and 'after' intercooler. Didn't quite associate 'outlet of the turbo' w/ before ic.

My bad.
