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, 2009.
With a rigorous 7,000 miles to be covered within a week, and to compete against the likes of Porsches, Corvettes, Nissan GTRs, would be the testing grounds for the new Generation Active Autowerke supercharger system. The Active Autowerke new HKS GTS 8550 supercharger not only proved its worth by being 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 6 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 6 will deliver exactly that. Consistent, repeatable runs of over 420 WHP (510 engine horsepower) were also recorded on the Active Autowerke 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 are under such conditions, since higher horsepower numbers will only increase as the temperature falls and the air becomes more dense.
The stage 2 System boosts the S54's power output to over 600BHP and includes an upgraded fuel system (includes two fuel pumps, fuel filter, all new -6 lines, fuel pressure regulator, dead end fuel rail, upgraded injectors and all required fittings). This ugpraded fuel system is a must once reaching these increased boost levels due to the fact that the factory fuel system is simply inadequate at this level.
The stage 2 system also use a larger front mount air to air intercooler and our custom methanol injection system.
Power : 605 BHP @ 7000 rpm
Torque : 395 ft/lbs @ 5400 rpm
Boost Level : 11-12 psi
