I've only had this particular car to the drag strip a few times with club events, but as I understand trap speed should be pretty much relative to the power the car has on the particular pass and very consistent. As long as you're not running out of gear on the top end the rear gear ratio shouldn't make much difference for the trap speed. For the time it improves or worsens greatly as 60ft time changes. Harder launch and gear ratio to improve on the initial start would improve time. Every .1 second give or take for the 60ft = about .2 at the end.

I think the 275/60 15s Mickey Thompson ET street drag radials would hold quite a bit more power than I have. It just comes down to the track conditions for the day. On the street they're incredible.
