I have a 97 Cobra, my mods are in Sig.

Below are my best track times so far, I've only taken the cobra to the track 1 time, and this was on my 4th run ever in it.

60' 1.87
330 5.44
1/8 8.49
mph 85.2
1000 10.92
1/4 13.10
mph 106.2 !!!

All I did this run was heat the Nittos pretty good. I came out of the hole raising the RPM's slowly from 4k, and side-stepped the clutch 4700ish. I powershifted [email protected], powershifted 2-3 about
6800, and powershifted [email protected]

These are my dyno #'s from 4800-6900RPM, my range with 4.10's
I shift @ 6500-6700 on my 1-2 shifts, about 6800 2-3, and 6700 to 6800 3-4, I take fourth to 7k ( only gets that fast on the highway/street ) it helps 5th gear keep going.

4800 257.8
5000 268.7
5500 268.2
6000 274.6
6500 263.5
6700 257.4
6900 252.3

I'm gonna get a dynotuned chip, BBK lt's, and imrc deletes. We'll just be cutting the Mac o/r h until I can afford a good o/r x pipe, and a good stainless catback, which I'll do a dyno comparison for an o/r x v.s o/r H.

I'll be posting my gains/losses, hopefully I'll make it to the track the same day and maybe see some 110mph trap speeds, and I'll defenitly finally see some 12's.

I would suggest spinning the motor a tad higher on the 1-2 shift. The T45 has such a big difference in gearing on the 1-2 that you need to shift higher. I would suggest redline and see if your time comes down some.

Lloyd,

Tried that, they came down when I started shifting as close to 6700 as I could guess. I make more power @ 4800 than I do @ 6800.. It makes sense :p somehow

I can't wait to see how it respons to LT's a imrc deletes and a dynoburnt chip :blob on the dyno and track. Than maybe I'll be shifting a little higher

Ths evry1

My #'s are a little on the strongside :D I think my times are from my abuse, obviously I was banging the gears the first time I go to the track, I come back, and 1 week later I need a new transmission:D
