Whats goin on everyone, im will and i am in the process of purchasing an S4... i spend about 6hrs yesterday reading you guys post and finding out things (you guys really know your stuff)..but i still have a few questions...WHAT EXACTLY IS A DV? what does it do? does it make a sound? someone wrote that it makes a popping sound, i was just wondering.....

and also this may be askn for much, but is there a list of things i can do to achieve maximum hp BEFORE purchasing K04's? is there any order in which i should upgrade? thanks for helpin out

 

here is some good info on the car and what most peopledo to upgrade https://www.audiforums.com/m_406711/tm.htm
As for what is a DV is it does the same function as a BOV but a DV is in a closed loop system so you cant VENT TO ATMO, i know you can but you car is alrady takeing into acount it is getting that air back into the system and will run like ****. Hope this helps at all and good luck with your car finding.

 

thanks man i appreciate, however; does this diverter make a sounds? one guy said it makes a snapping sound...could this be what im hearing when i attend rally events? its doesnt sound like a back fire or a down shift....and also the link led me back to the home page :-))

 

The DV is REALLY quite, especially due to the stock airbox. No what you are hearing there is more of backfire... I think, but it's not the DV.

ok i got ya...do the are the KO3's spool up loudly, i heard the b5is a quitecar turbo wise...but this is comin from my friend who drives an s2k....what is the first performance upgrade u recommend other than tha darintake method?

 

get a chip, giac, apr, whatever. Because of the turbos a simple chip will turn s4's into beasts

 

awesome what kind of horse power gains would i see bro? and pricewise..$500? $600?

 

500-800 bones, and 50-80 hp, and 80-100 ft/lbs.

good luck, and keep utilizing that search feature!

 

70 more hp and like 90 lb ft. of torque increase is what I've been told. So that would put you around 320 hp with a chip intake, and exhaust mods.

The APR bi-pipe is a good part, not for adding power, but you never have to worry about blowing a hole in the throttle body boot and getting a boost leak.

Darrintake
Chip
"piggie pipes" which are downtubes from the turbo with the pre cats removed, helps spool faster and lower backpressure
high flow cats
a good catback exhaust system (borla, apr, awe, custom, etc..)
if a manual, get a short shifter, and later on a light weight flywheel (LFW)
if tiptronic, recode trans to 00032 for ability to hold 1st gear in tip mode (good for racing)
if you got deep pockets, get some APR intercoolers
RS4 cams

all of that stuff would put you at stage 2+

 

ok sounds nice, i will make a blueprint and go from there...now bodykits....i want that widebody look without having the full kit on..could fender flares work?
