60ft
How does the 60ft affect the 1/4 as far as ET?
Right now I've only done a few passes in my car and don't have much experience.
With 4.10 gears and street tires, traction is limited.
So far my best is a 13.5@104.5 with a 2.0X 60ft(prob high 2.0)
How does bringing the 60ft bring down the ET? I definitely spin for more than 60 feet-all of first and chirp 2nd.
Ex: what would a tenth off the 60ft bring off the ET? Let's say I cut a 1.8 60. WHat could I expect the ET to be?
Thanks!

There is a generally accepted consensus that a tenth *.1* off of your 60' will result in about a two tenth *.2* drop on your ET.
However, a lot more goes into effecting the outcome than that.
Having said that though, your trap is quite healthy and you're therefor leaving most of your time at the start. If your trap was significantly lower I'd say you had tons of time on the table.
If you had some sticky tires *like a drag radial* or were able to just drive the hell out of your car to a 1.8 60' I'd say you've got bottom 13's and maybe high 12's in the car as it sits.
I went from 14.5 with a 2.2 60' to a 13.6 with a 1.8 60', but there was a lot more than my trap affecting my ET. I was new to the car, couldn't shift hard or at the correct rpms consistently.
Good luck. Even a 13.5 isn't bad for street tires.

Like Mach said it's generally accpeted that .1 off your 60' timeshould equal .2 off your ET. For example last year the best I could get out of my car on street tires was a 2.2 60' and I pulled consistant 14.2-14.3s, I borrowed a buddy's DRs and made 2 passes and I was cutting 2.0 60's, and on the one run I didn't completly **** up I pulled a 14.0, but that was with a soft launch and an early 2-3 shift.

and I'm more hoping for the high 12s ;-) .........others with my mods get it, and over 300wheel doesnt hurt either.
I guess practice, practice, practice-----though this may not be possible on street tires with the gears

I recently went from sumitomo htrz street tires to some nitto dr's. With the same mods on both occasions, i went from a 13.6 with a 2.1 60ft. to a 13.3 with a 1.9 60ft. on my n/a runs. It was my first time on dr's. With practice i know i could cut a 1.8, and pull very low 13's.

Just like everyone has been saying, .1 =.2
Find yourself a pair of 275/40/17 Mickey Thompson ET Street Radials. Do a small burnout (3-5 seconds) and let her rip.
As a side note:
I swear the dyno I go to reads stupid low. I have the "same" whp as the OP but trap nearly 5mph more, its weird.
This is my best pass on streets

Like they say, you don't like your dyno numbers just find another dyno.

So I'm guessing it's no go on nitto 555 street tires then??
Also how does the stock drivetrain hold up to launching on DR's??
If I go to the track every once and a while and launch it,how will it affect my driveshaft, posi, trans etc...?? Am I gonna break the DS in two?
Thanks!
