OK, so for example 7200 RPM, 4.30 gear, 32" tire theoretically is 160 - 163 mph so 7% slippage would give you about 152 mph @ 7200 RPM.

My converter is slipping a little too much but my mph is way down from where it should be based on hp/weight. My combination is 2140 lb roadster / 680hp / 4.56 gear / 32" tire and I'm barely running 139 mph at the stripe @ 7100 RPM. Too low a gear maybe?

Thanks for the input.
