Aright, this is kind of a vent/need for advice. In late 2004, I ran a 13.15 and broke my 12 bolt in the process. So I got a 12 bolt and last year made some passes with the 12 bolt and a new Spohn torque arm. My best 60' with that setup on Nitto drags on the stock wheels was 1.93 and I ran a 13.08, but I was having some traction problems and had some wheel hop still. So this year, I got Spohn LCAs and a PHB. I finally got to the track on Saturday. I threw on the nittos again and had them at 16 psi. I was launching at between 4000 rpm and 4500 rpm. I was hooking up well mostly, and I was cutting 1.81 60's fairly consitently. I hit 1.79 once but could not do better. My best run was a 13.04 @104.56 mph with 2 runs at 13.06. I could not figure out what I could do to get better since I was hooking up and I felt I was driving pretty well.

My first question is, with my power and the 4.10s, is is possible I was launching too high because I don't have the torque to back up a 4500 rpm launch? Second, what else could it be. I know, just get some spray or a cam and it will fix it, but I decided to not get a cam til I can afford heads/cam package so I'm not going to be doing that anytime real soon.

Any ideas on what I can do to finally get into 12s, or am I stuck at 13.0 until I spend more. Its just frustrating that I spent $2600 in the past two years, and it has only made me gain 0.11 seconds in the 1/4. Any help would be much appreciated.

how are you launching it?? are you dumping the clutch?

Pretty much, Ive got a Spec stage 3, so there isn't much feathering you can do, but I don't totally just let it go...I just come off it real fast.

I have the spec 3 myself , you should be able to slip it some. It's not really even that aggressive of a clutch. At least mine doesn't seem to be.

Its not too bad, but I'm not just popping it...just saying there isnt much slip in it. No one else has any ideas??

Yes with your mods I think you should be faster. I thought 12 bolts where
nearly unbreakable. I noticed that your trap speed was a little low.
It could be just the weather. A new set of plugs couldn't hurt.

Just to clarify, i broke my 10 bolt, then i bought the 12-bolt. That isn't the rear end i broke. Thanks for the thoughts.
