anyone ever use the onboard temp sensors?? I am thinking of getting one, but not sure it they r worth it, or if I should just stick with the temp guns. If anyone has one installed on their vehicle, could you please post a pic. I want some ideas on where to mount it. Thanks in advance.

I have one, the Venom one actually. My buddy at work, who helped me fine tune my engine, has one, temp gun that is, and the temperatures were only a few degrees off from each other. I don't think its needed if you have the temp gun already...

BTW, how's wildwood these days. I'm from Pennsylvania orginally and we used to go down there every summer. Do they still have that Galaga machine and Mr Doo at Uries still ? Did Zabers burn down any more times?

I like mine. It also has the feature of letting you check what your maximum temps were while driving. A temp gun cant do that.

Here is a picture. Its the little green thing on the back.

yeah, I noticed that they had that option. I dont have a gun yet, I use one from work when I break in an engine and tune it. These onboard gauges seem so convenient. Just was'nt too sure if they actually worked. How far down on the engine do you have the sensor cable or whatever it is called???

how much are they?

I have had a PC/rc Products onboard temp gauge for the last 8 years in my old RC10GT, and it has worked great. you HAVE to drill a mall hole in the head (easy on the side of a os .12CV), and screw in the sensor. Gives temps in Celsius or Farenheit, and constant temp or max temp settings. Cost was about $35 bucks 8 years ago...

I don't know if they are still in the market, though. Good, tough unit. I wash it with a toothbrush and soap, the tap water @ the sink to rinse it, and that's it. Just make sure you dry it out before powering up.

Hope this helps.

Mine was $13 on "E"-bay brand new. My sensor is 1 groove from the bottom on the heatsink. You are supposed to mount it even with your glowplug. I have a Venom mini-temp.

i've got the MIP one but I think I'm going with a temp gun now. Mine is just too much trouble cos I run my truck in the wet sometimes and I can't seem to waterproof it properly. It keeps getting wet and shoritng out on me. Then I'm stuck for the rest of the day not knowing my temps. Also, I just don't like having one more thing I have to mount on the truck. I'd rather have the option of just carrying the gun around with me and checking the temp when I want. Also, I tested mine by putting the probe in boiling water and the water started to boil when the gauge read 202 degrees. Needless to say, the gauge reads low by about 10 degrees. Even when the water was boiling hard, it only read 205...

There is a reason why it still reads 205... you should go look through a chem book or a physics book

*laughs* didnt you goto your sience classes? or did you skip to goto your gf's house?

Well CEO is she was hot then it would be acceptable.................but if she was ugly i think we need to whip a lil a can of banning on him......................so post pics![&o]

dude, boiling point of water is 212 degrees

On the Fahrenheit scale (°F), the melting point of water = 32°F while the boiling point = 212°F.

Therefore the degree size is different on the Fahrenheit scale with 180 Fahrenheit degrees = 100 centigrade degrees. Conversion between centigrade and Fahrenheit is achieved using the following relationship:

temperature (°C) = [temperature (°F) -32] * 5/9
