Active Autowerkes BMW E46 M3 Supercharger Level I- 440 HP description
Active Autowerke has considerable time researching how we could improve on the E46 M3 by way of forced induction and at the same time meet the following criteria:
Maintain the stock engine configuration without opening the engine.
Make it a true bolt on system that is available in "kit" form, whereby most all parts are "plug and play".
Add 100 more HP at the flywheel without any "excessive damaging" stress on the engine.
Do all this at an even lower engine speed to further increase reliability of the engine and the supercharger, which will decrease heat and friction on all moving parts as well.
Be able to run pump fuel with as low a fuel as 91 octane.
Do all this with the lowest boost level as possible.
Be gentle on the driveline.
Maintain the same "M Style" powerband, and at the same time enhance it.
Keep it affordably priced.
Keep it affordably priced.Be able to fit all versions around the world. (except CSL at this time)
We achieved these goals by using the Rotrex C38 supercharger, which gives the motor a gentle 5.5psi air-to-air intercooled push. The result is an astonishing 32-35% increase in power at a lower RPM limit of 7600 RPM vs 8000 RPM from the stock configuration. This just goes to show how well a heavy breathing motor like the M3's responds so wonderfully to a gentle bit of forced induction.
Rear Wheel HP @ 5.5psi Boost 345.7 @ 7600rpm More than a 80hp increase over stock M3
Rear Wheel Torque @ 5.5psi Boost 265.1 Ft/Lbs More than a 35 Ft/Lbs or Torque increase over stock M3
This Supercharger Kit Includes:
Larger C38 supercharger
5.5 PSI boost with over 440+ BHP at the crank
Front mounted intercooler to keep the power high
Front mounted oil cooler. The supercharger has its own separate oil system with reservoir
