Lynn,
The current question seems to be the hardness of the "Hurley" seals that failed
in Ed Anderson's 13B relative to "Tracy's" seals or even stock seals.....Also the
wear of his apex slot seems to be a factor........Correct me if I am wrong but I believe
your 12A engines use 3mm carbon racing seals........If this is so I would presume
they are much softer than stock seals.........How much racing at 8-9000 rpm do you
get out of them and where are the wear patterns located........seal surface,side etc ?
Thanks,

What HP range would you estimate your engines spend 90% of their time in?

We record and review each session on a video camera that watches a special
set of gages. I show the driver where he has dropped off of the power and he
complains about having to shift up here or down there and so on. We may then
change rear end ratios to get him out of a shift in a fast turn or such.
He is attempting to stay above 8,000 RPM. Max power is at 9,400 RPM and
shifts are at 9,600 RPM.
HP at 8,000 is 223 to 225. Max power is 244 to 245 HP at 9,400 RPM.
