Nitro temp gauge for motor?
 

My friend is letting me barrow his onboard motor thermometer from his T-Maxx. It has a wire that you loop around the header, and it gives you the current temp on the screen.

Could I use this on my 9L? Could i wrap the wire around the motor, and would the readings still be accurate?

Yes, you could use this temp gage. HotnCold used to have the same thing on one of his motors and it worked great.
