This passed week I swapped a stock converter for a YANK SS4000. I also installed a SPOHN adjustable torque arm and rear control arms. As you can see from my sig... what my bolt-ons are and my current 1/4mi. performance. My question is... what would be a ball park figure of performance (60ft.) that this upgrade (should) give me? Thanks.

 

You should be able to pull consistant 1.6 60's and maybe 1.5s

I will say 12.2s all day, the mph might go down a tad though

 

I think you should be able to pull 1.5xs all day.
