Right now i have squeezed out a best of 13.39 with a 1.90 60ft on a soft launch. That was with a bad MAF(made it run way lean) and on nittos. Since then i have done 3.73's, got tuning done, and got some et streets. I have a converter, lt's, and cai. So, there isnt much left as far as bolt ons. i really want to hit 12's with just bolt ons. My question i guess is, if i do a aluminum driveshaft, and underdrive pullies will i see enough gains to get me there?? Or are these two mods going to help me at all?? Thanks

 

In my opinoin a aluminum driveshaft and pulleys MIGHT gain you 2-3 rwhp, in other words they wont help at all for the cash your going to drop. Maybe bolt on a NO2 bottle? Higher TC? A catback might help a little bit maybe a tenth. 1.6 roller rockers, if you consider that a bolt on. Suspension mods, LCA/Panhard Bar/ STB/SFC etc. You should be close...but your definately not going to make it with a Driveshaft and pulleys.

sorry i guess i should have been a little more clearer also. I have a cutout and i have lca relocation brackets, with lca's.

 

If you've got the gears, tuning and ET streets after the 13.39, I think you should be able to hit the 12's then.

 

Should be able to go 12s with those mods.
