Spokane County Raceway

At Spokane Co. Raceway, the clocks are NHRA corrected for alt. most the time the corrected alt.is 5000' per Spokane airport data, it can get as high as 5500, which it was last week at the E.T. finals.
It was 3500 yeasterday, yet it was cool.It was also very humid. As of 9 PM tonight (sun), the temp is 66 degrees, but the desity alt.@ the Air Port is 3300'.
With that said, whatever the altitude is, if you run @ Seattle, your car will run as much as 4-4 1/2 teeths quicker.Maybe even quicker @ Bremerton.I run 11:20's here, I ran 10:80's @ SIR
That is why our track index is set for S/St @ 11:10 S/G @ 10:10 & S/C @ 9:10

But you are correct, the actual altitude is about 2000'.
