2001 SS. 425 HP goal...help. Hello, everyone. I am hoping I can have some help from members who have a similar goal as me, or accomplished what I am trying to do. First off, here is what I have...
2001 SS A4 343 rwhp, 353 tq
-SLP underdrive pulley
-160 degree thermostat
-373 gears
-K and N cold air intake
-Ported throttle body
-American Racing Long Tube Headers, high flow cats w/ Magnaflow cat backs.
My goal is to achieve 425 rwhp with more down low and midrange than up top. I eventually will take my car to the track and will probably a couple times a year eventually. The focus is set up for weekend driving and streetability. I dont want the car sounding like a tractor pull vehicle with a wild cam, but I am certainly not opposed to some minor lope. If anything, I wouldn't mind a cam that is on the quiet side for sleeper effect if that's even possible. I really am interested in the 215cc cnc'd trick flow heads, and probably a custom cam that matches the heads for the goal I have. I know a stall will be needed, so wondering what range you all thought?
If anyone has an a4 ss or z28 and has a similar modded car that I would like to build please let me know what you have and if you like your build. I want to stay naturally aspirated, and am not interested in NOS, superchargers, or turbos. I know a good tune will be in order , but I dont think 425 is too out of the question with what I would like to achieve. Hope to hear your thoughts.

ya a full bolt on ls6 car is around 400 with an m6 and 380ish with an auto. 425 whp would not be a problem with trick flows honestly you could do afr 210's or trickflows and then add a small cam (high 220's duration) and you would meet if not exceed your goal. If you wanted to keep it on the cheap side a set of 243's and a decent sized cam would meet your goals

I think the TFS 215s, TFS 220 as cast or Ported 243's and a mild cam will get where you want to be.
Maybe Futral F-11 or F-13
Texas Speed 228/228 Cam
EPS 226/230 or 226/234 or 230/234
However, please do not forget to get a new higher stall torque converter. Heads and cam w/out new converter is all for nothing. So save cash back for that too.

Seems like people get too caught up on dyno numbers...why? Bragging rights?
Run the car at the track, go grab your 13 second timeslip then install a 3500-4000 stall converter and run low 12s, you'll be happy. Forget the dyno numbers, only way without a mid sized cam is nitrous or forced induction.

425 is a lot to put down, especially through an AUTO (with your given restrictions above).
Why that number? Why not a track time goal?
Here is how I see it, lets say car 1 and car 2 race with the following mods:
Car 2: 425 RWHP through a cam/heads/bolt ons setup
Car 1: Drag slicks/radials, some suspension work, and a nice 3800 stall.
From a stoplight, I would take car 1 every day of the week, it would annihilate the bolt on/cammed car without tires or a stall.
Now yes, Car 2 would probably win from a 60 roll, but you said yourself, you want low/mid range power. That would mean a stall, gears, suspension, and nice sticky tires.
Just my opinion.
You can contact any vendors on here and let them know you want 425RWHP and they can throw a nice setup together for you, but unless you are doing 60, 80, 100MPH roll races I would get the fun mods first. besides, 100MPH+ roll racing is better suited for a turbo setup (which is the opposite of what you want) as the turbo spools and makes HUGE mid-top end power.
