Hello, Im new to the Audi scene. Actually, never really been interested in them ever since I recently got my S4. To me, it's pretty slow. No, im not a troll or want to start a flame war, but I came down from a 611rwHP 03 Cobra which pulled at an speed like nobody's business. Now, I know that the new S4's probably arent capable of these same numbers, but is there any way to fit a turbo or supercharger under that crammed engine bay? How strong are the internals? Will I have to buy some forged rods and low-compression pistons? Will the rest of the drivetrain be able to handle this increased HP and TQ? Thanks for the replies.
