I was wondering what type of gauge/sensor should be used to measure the temperature of the incoming air in a Forced Induction system?
Would a ambient air temp one that works up to 225 degrees work?
Thanks,

I was just digging around for my supercharging book to look into that but I can't find it, you have me curious now.

You're talking about monitoring the air temp of the compressed charge going into the engine, right?

I suppose if you are in a warm climate and the supercharger is ingesting air at about 100 F ambient it could be a whole bunch hotter from the compressing and shearing action of the blower, but how much hotter I don't know.

If you were running tons of boost I suppose you could be getting up to/past 225 F, but at 10 lbs I don't know. The 'Street Supercharging' book has some graphs depicting typical charge temperature increase vs. boost for roots-type blowers.

 

Actually, it is a turbo application (even hotter) running though a IC. I'd just like to know what my air intake temp is, mostly curiousity. But yes, that is exactly what I was asking for... but unless I go with a rather expensive exhaust gas temperature one I can't seen to get over 225 degress, and I don't really need to go up to 1000 dgerees or whatever w the EGT...

 

I guess an auto transmission temperature gauge would read between 225 and 1000 F but likely very slow to react to temp changes getting on and off the boost.

There probably is an industrial remote-sensing pyrometer for the job but likely really pricey.

 

Yeah, I guess I will go w/ a 0 - 1000 or something EGT. Too bad they are like 100 bucks, but I guess that isn't bad.

 

A coolant temperature gauge that uses a factory type sensor would be about the right range for IAT sensing, and the sensors are readily available.

 

Sweet! That is the answer I was looking for! Thanks!!
