    Anyone know what the max temperature and pressure is in the fuji blue engine exhaust?

    I am considering adding some temp monitoring on my next rebuild, thought it might help for tuning and help to prevent burn-downs.

    I am thinking as high as 1300F temp-wise. But not sure how to figure the pressure.

    Thanks!

    The 1300 degrees is just about ready to melt on an OMC outboard. What is the purpose of monatering the pressure?

    I am not monitoring the pressure, just want to make sure the temp measuring components can handle the pressure.

    The thermocouple wont be bothered by pressure. Only the tip is exposed to the hot gasses. I have seen thermocouples mounted thru head bolts with the tips right in (behind) the exaust port. Dave Bush then had Six pyrometers to monitor each cylinder independently and could ajust the mixture for each cylinder with his EFI set up.

    Well technically they DO have a pressure rating.
