[jlgroovetek]

Greetings from down under; your S4 looks and sounds great; perhaps the sound is abit too much down low but awesome nonetheless.

I wonder why there's so much fuelling on the overrun though... can't be good for your cats (if you're running em)!

I'm love my Stage 3 too!

[SickAudi]

Thanks!! That means a lot coming from the motherland. :)

[alexknecht]

@AudiSportB5S4 I believe its the fatherland. At least if you talk to my grandparents it is.

[audis4ification]

@AudiSportB5S4 mmmm the motherland :D <3 Germany!

[amdisthebest]

@Sebastian3103 Not quite the best engine...and I own one of these. I5 FTW ;) 

[mtroy89]

hmmm whatcha sayyy

[bikerboomer]

damn, just picked up my s4 and im not far from vast... now i wanna go get some parts installed... how much power did this put down?

[AudiSportB5S4]

@bikerboomer

I haven't dynoed the car on this setup... I have dynoed back on an older fueling setup without the water/meth injection and the car put down 350/405 on a hot summer morning... I would estimate the car is ~400 WHP/425WTQ..

[bikerboomer]

@AudiSportB5S4 as far as the tune goes, what boost numbers are you seeing and tapering to at high rpm? and how much ignition timing did you add after meth? i can see you gaining more than just 50hp depending on how much you upped the boost and timing after meth. i know on 350whp wrx's that add meth they usually see between 80-100 whp gain with meth injection and increased timing. very sweet car for sure, great setup.

[AudiSportB5S4]

My tune varies a bit because my boost is controlled electronically via N75. The winter tune I'm on now calls for a ~22.5 spike and tapering to 20 by redline. In the summer I run a 23PSI spike and a 21 taper because of the less dense air. I'm running 25* of timing up top with the meth injection. I was running 30-35*, but it was too much and the car was running a bit slower. Thanks for the compliments!!

[jlgroovetek]

@AudiSportB5S4 How much timing do you think you can screw out of running meth? Because 25deg doesn't seem like alot at 20psi towards redline with meth; don't most K04 Stage 3's run about that without meth?

[alexknecht]

sounds delicious

[Rootmachine1]

oh yeah

[AlexZTuned]
