There were a few other changes other than adding the 4.10's that contributed. I took everything out of the trunk, the passenger's and rear seats out, which were there last time when I ran the 13.34. I also reset my pinion angle to make it less aggressive, and changed from the 135% to the 85% setting on my Megabite SR's which improved traction a lot. While the BFG's were aired down, I put the stock wheels on the front with a set of 215/50's on an 8" rim aired up to 50lbs.
I also took out my CAI, and was running no passenger's side headlight, so the air was blowing straight into the MAF sensor, no filter was there.

So, while the majority of the gain was swapping from 3.27's to 4.10's, I did everything I could to make sure I got that 12 second slip.

And your trap speed went up like 2.8mph which is sweet. I bet you could a 12.7/6. I think thats the first 2V ive seen hit 12's without cams/longtubes. Thats impressive man.

For around here, it's not really that impressive, I guess. A buddy of mine with a GT with basically the same mods as I have, except he has throttle body and plenum has run almost identical times as I have all the way down the list, since him and I bought our cars at around the same time, and have modded at the same rate, pretty much.

When I was running 13.60, he was running 13.64. When I went down to a 13.34, he ran a 13.40. Since then we've kind of went different ways, I went 4.10's, he went 3.73's, so it'll be interesting to see the difference. I also installed a panhard bar, he didn't, but I don't know if that makes any difference at the 1/4 mile.

I also expect that once the weather starts to warm up, and I lose my negative DA, I'll be a bit slower if I don't continue to mod. -1200ft DA makes for some nice runs.........

Still hitting 12.9 @ 105mph is still really good bro. Theres still a lot more in it. And you got a 1.74 60foot thats sick for drag radials. I definatley see you hitting 12.7 or 12.6. Nevermind with longtubes and cams. Youll be deep 11's for sure with some M.T's
