Just wanted to say - great forum here. Loads of good info which is what I like to see! I'm taking a different approach and I am looking into modifications before purchasing the vehicle; I want to hit the ground running so to speak and have all my research started / completed. In 2 weeks, I'll be looking to pick up a 2012 45th Anniversary edition A6 V8 w/ 19K miles on the clock. My plans for the vehicle are for it to be a daily driver (for now, due to change within a year) but make some runs at the strip. My goal is to reach about 425-500rwhp (if possible w/ the auto). I have NO interest in going FI. Keeping that in mind, I have composed the following list of modifications that I look to do to the vehicle:
1 7/8 Kooks Long tube headers w/ HF cats
SLP under-drive pulley
3600 Triple disk converter by Triple-D (need to know cam specs first)
Cold Air Intake (not disclosing, I have read how you all can get when disagreeing about these)
Ported Vmax TB for the L99
3.91 Gearing (this is what I have read as the "best" for the L99...please advise if I have misunderstood or it has changed)
ADM Transmission cooler
Cat Back Exhaust (undecided, whatever hooks up best with Kooks if that is known - please advise)
Ported Intake Mani (would do this later on and I have seen people go back and forth over it but figure if I did it after all performance mods it really couldnt hurt...right?)
Tune - down on the list but I understand the importance. I've read dyno tunes are the way to go hands down. If not, seems the Diablo Predator might be a good backup for receiving custom tunes? Please advise. I live in
Maryland so if anyone knows any tuners that are familiar with our emissions standards (PLAGUED me with my last car) in / around me and can deliver a good tune while allowing me to pass emissions I am all
ears. If not, who can I look to in order to have custom tunes sent to me; and if this is my only option could you provide recommendations and hand helds I should consider?
Where I really need help is in regards to the cam, oil pump, and suspension. I have seen information stretching across 6 years and a multitude of information. I need what is current and best suits my wants...
Cam: I've read both arguments that swapping heads is a must and that you should leave them alone and the L99 is more than capable. What would be my best course of action given what my end goals for the vehicle are?
: If a L99/LS3 conversion is needed - what all do I need to look into replacing? I have seen Vengeance (Night fury?) and TSP VVT delete with the 231/236 recommended.
: Those who have said a conversion is NOT needed have said the ADM Stage 2, TexasSpeed, or MastMotorSport with the 3600 Trans. cooler is all that is needed for an effective cam.
Oil Pump: What brand would you all recommend? Is there a ZL1 model that can be popped in? Whatever is best because I have limited info regarding this.
Suspension: I need a little guidance here. DD/drag what would be my best option? - Looking for what helps with better hook-up but allows the car to be handled for DD activities, not going through hairpins at 95 MPH...
: I've looked into strut towers as well as sway bars
:Strut towers: I've narrowed it down to the ZL1 or the BMR 4-point. Which would you all recommend keeping my goals in mind?
:Sway Bars: I've seen it mentioned that these aren't wanted if you are going to be dragging the vehicle since it messes with the hook-up...Need some opinions on this.
I apologize for the wall of text but I wanted to provide as much information as possible as well as what has been asked in past posts in regards to these questions in regards to cams. Appreciate any and all input!
