Too little advance moves the heat to the exhaust as the fuel is still burning in the manifold/turbo, that's where the higher egt #s come from with retarded timing, but too much advance makes the combustion hotter, which also raises egt's.
One of the reasons why you can't rely on egt alone to tune a motor. |
I was about to mention that too much retard will also run it too hot. This happened to a friend of mine and it ended up overheating the turbo and the seals got cooked....which made for a cool Spy Hunter-ish smoke screen on the interstate...but destroyed the turbo.

Curious what Corky/Tim say. With your build and intended use I'd say the EGT was a must. Very suprised you didn't have one. Problems suck and I know you were more than a little concerned about them. Goes to show being paranoid doesn't mean people aren't out to get you!

I can't count how many times people on this board have steered folks away from EGT gauges claiming it's not useful in the day and age of A/F gauges.
This post reaffirms the importance of knowing EGTs for me. Something was obviously getting too hot. |
well the stuff is on a UPS truck on its way to San Antonio. On a lighter note, I just ran 2-sessions at the indoor karting place in OKC in business attire and set the #5 lap time on my second session, lol. Not bad for a 190lb old man competing with a bunch of children. Its also notable that I did this in a pair of Salvatore Ferragamo's, lol. Unfortunately the record is still 2.5 seconds faster than me so its going to take a miaracle to get to the top of the board...or talent, and I have neither.

maybe this will inspire me to call kelly and order-up some water.

Ferragamo makes pumps in your size?
