Re: Intercooler thermocouples?

Yea, I think I'll go with a open element GM IAT sensor - although I hear that some have vibration problems. But at least bungs in aluminum and steel are readily available.

Re: Intercooler thermocouples?

Thanks jharvey. And interesting link.

Intercooler thermocouples?

Does anyone know of a good supplier for a thermocouple that would work well, and mount up nicely to the in and out of an Intercooler? I'd like to be able to read incoming temps, outgoing temps, and calculate the difference. but I can't seem to find a nice pre-made automotive thermocouple? Any advice?

Re: Bench top power supply....

That is impressive. I have nothing against building a PS from scratch - but I just have too many unfinished projects as it is - last thing I need is to be banging my head against the wall with another one. I'm building some custom automotive gauges (volt, AFR, ect) so I want something with a real ni...
