Just ripped off a new best:
Mods: 4.10's, K&N drop in, hoosier DR, o/r X, Mac mufflers, FRPP C springs, tokico blue shocks.

1.98 - 60 ft
9.0031 - 8th @ 78.37 MPH
13.9787 1/4 @ 98.40

Used the drag time calculate for DA and it corrected that pass to:
13.706 @ 100.399 MPH
 
Corrections are fun to play with, but really don't count IMO. Correct my best pass of 14.01 and I ran a 13.67 @ 101.6 mph. Not a chance this NPI would run that kind of time with just a PI intake, H-pipe and a K&N. :lol:

Anyway, it must feel good to run a 13.xx. Comparing my timeslips, I got a similar low 2.0 60' time, but was down a good 3-tenths at the 1/8th. Clearly, your gears are making up some nice time between the 60' and the 1/8th compared to my 3.27 geared car.

I don't use it to brag, I use it to see where I'm at compared to others. Someone at a sea level track with perfect weather is going to run much faster that you. That's the numbers you see in magazines.

Breaking 13's in a basically stock SN95 is nice, but I'd love to make the 100 MPH club.
 
so can someone edit the first page i think im 2nd i wana say lol
I have to work on a format that makes sense. The way the data looks changes with individual settings. I've asked for a database separate from the forum but got zero traction from the powers that be. I'll work on cleaning it up and making sure everyone gets listed.
 
Finally ran in the 11's end of last season. Tried to go quicker that day and manged a 1.51 sixty after this pass but I'm out of fuel. Got what I wanted NA. Now finishing up motor that was to be supercharged but switching up and going with a turbo now.
