AA SC Kit w/ Rotrex Blower Level 2 (E46 M3) w/ Methanol Fuel System (AA Part No. AASC-E46M3L2-6Spd)


Race on Sunday, to sell on Monday. This old saying is indicative of the new BMW M3 supercharger system. This generation 7 Level 1 supercharger kit for the E46 M3 has been through countless hours of testing. It has often been quoted that the true test has always been a race environment. What better venue than Brock Yates One Lap of America Race, back in 2009. With a rigorous 7,000 miles to be covered within a week, and to compete against the likes of Porsches, Corvettes, and Nissan GTRs, this would be the testing grounds for the new Generation of Active Autowerke’s E46 BMW M3 supercharger system. The Active Autowerke new HKS GTS 8550 supercharger not only proved its worth by powering the highest ranked BMW within the field, but came 1st in its class.

The data and technology that made this winning combination is now being applied in the new Generation 7 of the Active Autowerke supercharged E46 M3 level 1. Reliability and power is needed if you want to be on the podium, and this new Generation 7 will deliver exactly that. Consistent, repeatable runs of over 420 WHP (510 engine horsepower) were also recorded on the Active Autowerke Mustang chassis dyno in hot 94 + degree Fahrenheit conditions with humidity in the 60% + range. These run conditions might be considered a deterrent and not really suited, but it is better knowing the horsepower numbers under such conditions, since higher horsepower numbers will only increase as the temperature falls and the air becomes more dense. Make sure to employ a proper BMW M3 Signature Exhaust for maximum power output!
