This kit will give you the ultimate performance from your B7 RS4 with a stock engine with long term proven reliability.
This kit upgrades our stage 1 supercharger kit to a air to water intercooled setup with MUCH colder air and 1 to 3 lbs more boost. We have been running this kit since 2012 on stock engines and have found this is far as you want to go with stock ring end gaps on the stock engine. Customers of ours and the JHM team have ran low 11 second quarter miles in the 123 to 126mph range.
Unfortunately with stock piston ring end gaps even with our low EGT software you cannot make more power without colliding the rings in a short period of time. For those with a built engine with larger ring end gaps at a minimum and ideally better rods and pistons (limit of stock engine) we have smaller pulley combos that we have gone as fast as 10.7 in the quarter mile at over 130mph. Inquire for details if you have a built motor and want more than this kit can offer or if you already have this kit and are ready for the next step.
