intake temp sensor? can i use a egt?
i am gathering parts for water injection and am down to the last few. so here is what i need to know.
What do i use to read the intake temps, can i mount a egt in the intake after the IC and before the TB? Thats where the water injection nozzle is going so id like to know what its doing.
Now how about a temp switch that turns on when the IC gets to a preset temp. I want to run a sprayer to it while im plumbing and pumping. I get water pumps from work so the expensive part is out of the way.
links or pics would be a big help.

water injection is cooling things in the combustion chamber isn't it? not in the intake. so seeing what it was doing would actually be seen with an egt sensor in the exhaut.

ok so how about the second part to my question...
where to get and where to mount a temp activated switch for a IC sprayer.
on, before, after, inside? what reading do i need it read..

Autospeed have done articles on two different intake temp displays.
The first uses a quick-response thermocouple and a back-lit LCD display. It required some knowlede of electronics to put together, but this is by far the best way to do it. You can measure both intake and exhaust temps. I've yet to find anything that looks like it could do a better job, including the stuff from big-dollar Japanese brandnames. Click here and follow the links though the four-part article.
The second is much cheaper to buy and requires no assembly, but it uses a slower-resonding thermistor and the LCD display is not back-lit. Click here to read the article. I've just bought one of these but haven't fitted it yet. It's going into the rubber intercooler-to-throttle body elbow so I can monitor some planned intake and intercooler mods...

Haven't we ALL heard this
I came across a nice intake temp gauge. It was ment for aircraft. However, it has two probes.
And the display could only display one temp at a time. However, it did have a neat thing. It would tell you the differential temp. So it would tell you the temp drop due to the intercooler.
It was about 170 bucks but I forgot who made it. I have the paperwork at home on it.

Intercooler inlet temps get into the two hundred degree range with regularity under hard boost. Just FYI.
And that's on a stock series four. You don't want to know what they are during the summer in Texas
And you'd be surprised how effective the stock intercooler is on a series four.
I measure with a Fluke 52II. One probe stuck in the rubber hose prior to the intercooler (in the air stream), and one after the intercooler. The fluke readings are instantaneous. No hanging out and waiting til it's too late.
I recommend AutoSpeed. They're always doing interesting things.
And as a side thought......I'm somewhat surprised there is hardly ever any mention at all of the temps prior to the intercooler or after the intercooler on this or the other site. Just talk about this or that big *** intercooler but never any talk about the temps they saw prior to the installlation vs the temps they saw after the installlation. Just talk, talk.
No, I take it back. I'm not surprised...at all. (slam fyi)
