Bolt-on M-8 Supercharger Adds 75% More Power

ProCharger (Accessible Technologies) has announced that its new bolt-on supercharger system for M-8 models is now shipping. Boosting stock power output by a claimed 70 to 75% hp, "bolting on 75% more horsepower has never been easier," says the Lenexa, Kansas based manufacturer.

"The wait is over for our all-new Milwaukee-8 supercharger. 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."
According to Sales Manager Walt Sipp: "ProCharger high-output intercooled systems are designed with durability in mind and provide 10 psi 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 once the engine guard is taken off."
A 100% stock 107" M-8 is said to get a boost to 140 rwhp and as much as 169 rwhp with a cam and a 2-1 exhaust. "No fluff, no hype, just the real world numbers you can expect to make. These are the kind of numbers you FEEL every single time you twist that throttle back."
ProCharger has made some drive changes to its latest supercharger systems for late-model H-D Touring bikes (Baggers) that use two dry belts (not running in oil within the bike's case) with the same "proven and reliable B-1 supercharger head unit and a large air-to-air intercooler." 

The high-output intercooled system is said to produce the coolest charge air temps and largest power gains with "smooth boost/power on-demand, for superior riding performance. The air-to-air intercooling provides consistent, reliable power, with no moving parts. The all-new dry belt design provides a long lasting belt life, even in extreme environments."
A high-output tuner kit is also available, which Sipp says "makes sense for someone wanting to perform custom tuning of the bike and push the envelope in performance. They would most likely be experimenting with alternative fuels and changing engine components like heads, headers, exhaust and cams for the engine." Optional upgrades for the supercharger include polished or black finish.
