mini superchargers
« on: September 26, 2018, 02:03:17 pm »
The other day, I stumbled across an ebay auction for a mini supercharger (Aisin AMR500). What really piqued my interest was that it only cost $225. Huh? No way! It had to be some cheap Chinese novelty part that would only last a few days, right? Turns out it was legit. These are low mileage (supposedly) used parts from a Suburu model that are only marketed in SE Asia. There is even a smaller version available (Aisin AMR300). Apparently these tiny superchargers have been around for about 8 years, but are just now making a big splash. The VW folks and other small displacement car guys are using them. Some folks (mainly Australians I think) are putting them on motorcycles now (mainly for racing). That's what started me drooling. Can you imagine a ZG1000 running at 5 or 6 psi boost? Holy crap! I bet traction would suddenly be a problem.

The following was quoted from a website called Supercharging Unlimited.

Quote
Unofficial Specs for Aisin Model AMR500 New Mini Roots Type Supercharger.

Application: to increase performance on motorcycles, snowmobiles, ATVs, VW engines, Mini Coopers, Subarus, Nissans, Toyotas or any engine under 3.0L.

500cc/ revolution (30.5 cu.in.) With straight, 2 lobe rotors. It could be over-driven, and make good boost on a 650cc-1000cc drag bikes or larger if RPM is kept low. Or it could be under-driven for smaller engines.
Examples:

On a 500cc two stroke, with the blower being driven 1.5:1 with the crank, it would produce approximately 7 psi boost.

On a 750cc four stroke, with the blower being driven 1:1 with the crank, it would produce approximately 5 psi boost.

On a 750cc four stroke, with the blower being driven 1.5:1 with the crank, it would produce approximately 15 psi boost.

On a 1000cc four stroke, with the blower being driven 1.5:1 with the crank, it would produce approximately 9.5 psi boost.

On a 1600cc VW engine, with the blower being driven 2.1:1 with the crank, it would produce approximately 5 psi, but the engine RPM must be limited to 8000 rpm.

Additional Info: Max blower continous speed is 16,000 RPM Before this, these were only available in Japan! This would be a great blower for any small engine up to 1200cc ( depending on RPM ).

Over all length is 6.75", Width is 8", Height from inlet to outlet 5.5" The 4 bolt inlet & outlet flanges makes it easy to fabricate custom mounts for manifolds, and carbs. The drive pulley diameter is aprox. 3" but could be changed out to a cog belt drive quite easily. We have no info on what modifications are needed to mount this unit on your engine. You will need to be capable of doing custom fabrication.

Summit Racing has a good book on supercharger applications called Street Supercharging. It sells for about $18, and is a good source of set-up information. It uses any OEM supercharger oil, such as Ford (a roots type supercharger was used on the Thunderbird), GM (the Bonneville SC uses a roots supercharger) and any of the aftermarket roots supercharger manufacturers such as B+M, Magnuson or Weiand.
