AMD is the way to go. http://www.amdtechnikusa.com/s4.asp . I have an 04 S4 with AMD stage 1 chip and stratmosphere hyper flow, short shifter and I'm very pleased with the results. Theoretically I should have 395HP, although I have not put it on a dyno. I will be doing the AMD stage 3 this month, they are coming out with 2 3/4 piping. I also have IFORGED Swift 19x8.5 wheels on Michelin PS2's. I have replaced the springs with H&R stage II springs and replaced the sway bars for H-sport kit. RIDES CRAZY!! [:@]

To answer your question about the supercharger AMD is coming out with a supercharger kit that will fit the S4 nicely by taking out the intake manifold if I'm not mistaken. There are two stages, Low Blow and High Blow. the low blow is good for about 500hp (no intercooler) and the High Blow which requires an intercooler will be over 600HP and it arrives in US in December. I believe the cost will be about $10,000

I'm personally going with the Low blow kit first. I'll let you know guys know how it all turned out once I kick my bro's E55 to the ground.

Um if it replaces the intake manifold then its a roots or screw type supercharger. both those superchargers have intercooler built in under the rotors. they call them heat exchangers and instead of cooling them with air they are cooled with antifreeze. which does abetter job of cooling the air but you better make sure that you dont run dry.

OMT i didnt see anything about a supercharger on that website

Good lord I can't wait for that to come out!!!!

Please post more info when you get it, I wanna study that thing inside and out!!
