Wow...barely trapping 90. I will have to cut a serious 60 ft to get into the 14's with that trap.
A trap speed is the the MPH your at when you cross the lights at the end of the 1/4 mile. 1/4 mile times are driver dependent while trap speeds are solely based on the power the car is making. You can cut a terrible 60ft and run a crap ET (quarter time) but still be within a MPH or so of your average trap. If you need anything explained further I am happy to help.
