How would you reach this 1/4 goal? Input appreciated :)
Goal: 140mph trap speeds on the 1/4 mile in full street trim (minus rear drag radials)
Car is a Z51 A6 daily driver /w lots of stop and go.
Current mods: A&A V3Si (9psi), TSP LT Headers, Alky Meth
Current state: 625rwhp ~130mph on the 1/4 mile
Things that I do not wish to pursue (at this time at least): weight reduction and nitrous.
What would be a good and cost effective way to reaching this goal?
Heads & Cam (mild to moderate)?
(BAMF) Cam only?
Larger S/C Head Unit + Forged Pistons (lower CR?)+ Increased Boost
Other?

The car would need more high RPM horsepower not more low RPM torque. So that could be a different cam as a first step.
But lower the car 1" with Penske or Bilstein coilovers and push less air.
Also, completely block the front air flow under the car with a front air dam. But that's very risky as it will produce a high speed aerodynamic oversteer
