i checked the ET database and didnt see anything relating to the trap speed.
the local drag strip doesnt have the times up but they do have the track open...

i did 13.01 @ 108 (5 damn times GRR!) in about 90 degree weather this summer in southeast texas 
i should have ET'd lower for the mods that i have, but i could only cut a 2.0 60', even on my 315 nitto's and 4.11 gears.
my car only had long tubes, true duals w/ x-pipe, and lid when i ran these times. now its got an ls6 intake, ported throttle body. as of today its got an f14 futral camshaft w/ underdrive pulley on the way.
i've seen big turbo cars blow the tires off for 1/8 mile and pull a 12.50 at 120 lol, trap speed is also a big factor in ROLL racing
keep in mind that it is referred to as "trap" speed because there is actually a speed trap system setup in the last 60 feet of the 1/4 mile. it takes a measurement of the time you take travling the last 60 feet and the "trap" speed is actually your average mph for that span.

Most forced induction cars will trap higher than a n/a engine that runs the same time. Trap speed also deals with traction. You can get a real good 60' and have a low et but also a fairly low trap speed. If you spin a lot then you will have a high trap speed.
There is no real way of accurately answering your question. You could have a 3 second 60ft for all we know.

i ran 13.599 @ 107.x with a 2.1x 60' in an M6....i don't claim to be a good driver so i'd say with a decent driver if in an M6 you should be <= 13.6 with a 2.1x 60'...
