[Land-speed] EGT

[Adin, David]

Dave D,
Stock Miata cams, timing as allowed by the ecu, a/f "low 12s" as I
remember.

I don't have a sophisticated data collection system (haha) and merely
read gauges after shutdown for the video tape.  Well, it works "sort of"
. . .   I remember the EGT being around 1800 and staying up there for a
while.

Not the best data point, but since the boost levels were close it seemed
worth mentioning.

Thanks for the input, I'm always looking to learn.

David in Durango
