Author Topic:   Exhaust Gas Temperature Guage
posted February 04, 2004 03:12 PM
A few years ago a motorcycle racing friend of mine told me he used exhaust gas temperature guages to keep track of his motor to make sure he wasn't pushing too hard. It seemed like a good idea, but I didn't think about it anymore.

After burning a piston last year, I am thinking about it again. Would exhaust temp guages be good idea to keep track of spiraling combustion temps? If so, what range should a small block (11:1 compression) be in?

Turbo'd cars and deisels also use them to let a driver know his foot's gettin' a little heavy. I know too many guages might confuse me, but I'm willing to take that risk.

Get the style that has lights in it, becauce you can not read the needle on an analog gauge. They seem to work well.

Nobody knows what the temps should be or maybe where to place the probe?

probe needs to be 1" to 1 1/2" from the header flange on which ever cylinder you want to check..

methanol..shoot for 1200 degrees

Its gonna be hard to tailor though..cause you may have another cylinder that is quite a bit different, only true way to check would be have 8 probes....

Well they make dual probes for each cylinder bank, so I figured thats as specific as someone would need to get.

Thanks though,

Did you burn the piston because you ran too lean? You might be better off using an air/fuel gauge. That would keep you from having to install all those probes. Just a thought...
