Harley-Davidson Milwaukee-Eight Intercooled Supercharger Systems: Now Shipping!


Bolting on big horsepower has never been easier! That's right, the wait is over for the all-new Milwaukee Eight supercharger system from ProCharger. No matter if you are driving daily to work, bike night, or across the country, this system delivers big power and big reliability. Unlike other high-performance options, idle quality and riding range are unchanged for nothing but smooth, predictable, and repeatable power.

  High Output Intercooled System with B-1  10 psi 70- 75%+ HP  1BL512-XX
  High Output Intercooled Tuner Kit with B-1  specify  specify  1BL500-XX

Tuner Kit: Does not include injectors or tuning device, although injectors can be added at time of purchase.  Both systems and kits will need to be tuned on a dyno.


ProCharger High Output Intercooled Systems are designed with durability in mind and provide 10psi of engine-friendly boost from the B-1 supercharger, providing years of trouble-free use. While being incredibly easy to install with common hand tools (for those that love the DIY lifestyle.)


No fluff, no hype, just the real-world numbers you can expect to make when you take your M8 bike to the dyno for tuning or verifying power output.  These are the kind of numbers you FEEL every single time you twist that throttle back.  

107" M8 Touring 100% stock  = 140 rwhp (rear wheel dyno hp)
107" M8 Touring with Cams and 2/1 exhaust = 169 rwhp (rear wheel dyno hp)


ProCharger has made some drive changes to its latest supercharger systems for late-model H-D Touring bikes (“Baggers”) that uses two dry belts (not running in oil within the bike’s case) and the same proven and reliable B-1 supercharger head unit and a large air-to-air intercooler.
