I'd like to add a head temp sensor to my 2 liter motor, i have the motor out of the car now, I like the idea of the spark plug gasket thermal couple, but it appears there is little room around the plug hole to get the wire out. Do you all grind away some of the metal on the head to install one, and if so which side is best to grind?
Also what are typical max. safe temperatures for the head? thanks d ave |

The plug is the only place for the thermocouple. Anywhere else will give a crappy reading that can be 100-200 deg low!
The wire can be carefully bent and brought out around the plug wire- no sweat.. 300-325 is optimum for a good comboed engine. Most stockers always run 350-365 and hit hills at 375-400. 400 is fine for short times... Start worrying at 410 or so at 425 you are in the area to have a dropped seat. Bigger engines run cooler if configured correctly- FYI |
