[does his best lynn hannover impression]



everything affects egt, timing mixture, outside air temp, oil and water temps.



most obvious thing, would be to richen it up, the extra fuel will help cool things down.



you might wanna look at timing, its prolly pretty optimum...



intake temps? oil temps? water temps?

Timing - 10 degrees leading and trailing. Should I advance or retard?

Outside air - 80 degrees

Oil and water temp - 200 degrees

Intake gets good outside air. My guess would be about 90 degrees

unless its a P-port, that tining looks a little retarded. more normal to see people in the 22-24BTDC L range. i would try 15btdc for a lap, and see where that gets ya

Mike is right, 10 is very retarded, the will cause the fuel to ignite longer in the exhaust.

Thanks guys. I relied on my memory for the timing instead of looking it up. It is set to 22 degrees. Sorry for the misinformation.

If I read that correctly, you are running zero split, leading and trailing firing at the same time. If so, that can raise the EGT's.

In a Formula Mazda the leading and trailing timing is the same. It never caused high egt before.

only way I've ever seen that high is timing as mentioned...

Thanks. I agree. BUT, I have been offered an explanation that hadn't occurred to me. If you run TOO rich, there is the possibility that you could have burning fuel, that didn't get burned in the motor, going through the exhaust port and creating an excessively high egt. It was suggested to me to consider that possibility when a/f to egt relationship doesn't make sense otherwise.



All I can do to test that theory is to wait for an opportunity to get on the track and lean this sucker down to see what happens. Racing Beat suggested using 240 fuel and 110 air. It seems to me that my current setup, 220 main and 160 air, should not be that much too rich.



I checked the timing an hour ago and it is correct.
