As the title states I'm seriously considering switching from my stock 3.05 Diff to the 3.29 diff.
I've got a few mods on N/A Series III that have pushed my peak torque up so high in the RPM range I'm dead in the water until I hit 3.5-4k. I can't even get spin when launching anymore.
I have ER Rockers which by themselves are advertised to move peak WHP from 5k to 5.7k, HV3 Insert, Wizaired CAI and both front and rear ZZP powerlogs. Before powerlogs I was at a 7.5-7.7 0-60. Now I'm looking at 8secs on a nice cool day and closer to 9 at 80-90 degress ambient temp.
I was wondering how much of an improvement in acceleration I could expect from stepping up from 3.05s to 3.29s.
I'm also going to get a mail order tune for the diff swap and the bolt ons. Probably another 20hp ontop of what I already have.
