not at all.....barely on the first mark....180, right with the thermostat. I verified temp a while back with an infra red heat gun. I do like the chocolate colored electrode. 99% interstate running 65-70 MPH @ 2300-2500 RPM with a few blasts to 100 mph just to check acceleration and vibration. Smooth as a babys butt.
If it got hot anytime, I would already be making it richer.
Comments are more than welcome.
