Jimmy,

My equation is reasonably accurate at around 300 watts.
Here's some sample tests from 6/8/99.

watts    toroid      predicted length    actual spark length
280     3" x 10"          29"                        27"
280     4" x 13"          29"                        27"

I didn't need to test a lot of different coils because my
equation is not for the average coil, but only for efficient
coils.
