I'm looking to make my A4 ls1 vt senator an 11 second car that can be also comfortably used as a daily.

Current mods are :
htv 1900 supercharger with 2 bar tune
twin 2.5in exhaust/extractors/cats
Strengthened engine internals and auto.

I'm currently pulling 311rwkw with stock stall converter/ 3.08 diff/ stock cam, and have never been down the 1/4 mile before (so have no idea where I'm currently at), but wondering what else I'd need to do to make mine an 11 second car.

My thinking is that a smallish cam, 3.7 diff, and some head work will get me to approx 370-400rwkw and somewhere between 11.0 and 12.0 seconds.

Having been down the (loose 4000rpm) stall converter road before, I'm hesitant to go down that route again.

Any thoughts?
