is there any company in the U.S making a supercharger for the b6 s4???

 

Do you have a B6 S4? if you do open the hood and look for a spot to put a supercharger. I know it could be done but you would have a supercharger stickin out of your hood.

 

I have heard a lot of speculation on various forums, but as far as I know nothing has been made available yet and I have not heard any definitive rumors of things to come. I suspect the answer may be what audi has planned for the new RS4, some say twin turbo V8, others say another twin turbo V6... I think its only a matter of time, but for now we will have to be satisfied with a new intake, exhaust, chip (that hardly does anything), and N/A. check out AMD's website stage 3 upgrades claim about 415hp but there is a lot of other stuff out there.

 

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 PS'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.
