Anyone run the Passon 4 speed overdrive at the drag strip?

I'm sure the 18 spline overdrive gear set is more than strong enough but how much RPM drop is there shifting through 1st, 2nd and 3rd gear when the car is really run hard?

Is it a major performance loss?

Any idea how much ET is lost with the Passon 4 speed overdrive setup compared to a regular Hemi 4 speed?
