Is the FM Dual temp gauge worth the money?? I'd like to know the efficiency of my intercooler at a glance and its the only dual temp gauge I can really find for intake air..



Kinda looks like an old Stewart Warner aircraft gauge.. but can't seem to find anything else.

 

It works, but it is fugly! I think Autometer makes something similar but it is not cheap.

 

To me this seems like something you would use for a few measurements and then be done with it. I can't see how your IC efficiency will change significantly ever. I doubt you will find any use of running it full time. Maybe you can buy it, use it for 2 weeks, then sell it off after you've collected your data.

 

Wastach makes those gauges. You can pretty much make any combination you want with a phone call. Their sending units for some gauges are super expensive.

 

i agree with him its is ugly. but you are right not many people make dual gauges for air

 

That's the kind of thing that is useful to see when you're on the gas compared to RPM and boost pressure, which means I want MS to datalog it.
