So as most of us know the 3.0 A4 has a very narrow set of upgrades available in terms of power to the engine. I have been trying to increase my knowledge of these products as much as possible and came around to the supercharger designed for the A4, the G3. After having read lots of reviews hearing both good and bad i would like opinions from members on this site (preferably those who have used this product :P)

 

The early models of the PES supercharger had problems, and the 3.0L engine isn't designed to be pushed past 300 horsepower. The PES kit pushes it to around 320 at the crank which is pushing it.
In terms of speed you would be about as fast as a stock S4, but you won't be able to stop like one, or handle like one. In my opinion, the 3.0L has enough probelms as it is and should be left alone besides the basic exhaust upgrade. If you want that speed save up for the S4, trust me its worth the investment if you crave a vigorous driving experience.
