Item specifics

Condition: UsedPart Brand: Aisin
Product type: Supercharger, Roots StyleManufacturer Part Number: AMR300
Displacement per revolution: 300ccWarranty: No
Questions?: Look me up on the net, just Google Duax Machine  

Here is an Aisin mini roots style supercharger.
 
Made in Japan, Aisin model AMR300

300cc/ revolution (18.3 cu.in.) with straight, 2 lobe rotors.
It can make good boost on a 4-stroke Bike or Kart engines.

New Aisin AMR300 blowers are no longer available.

These are an excellent alternitive to the crude Hansen superchargers.

Drive ratio/boost examples:

On a 250cc four stroke, with the blower being driven 1.0:1  times crank speed,
it would produce approximately 20 psi boost.
On a 305cc four stroke, with the blower being driven 1:1 with the crank,
it would produce approximately 14 psi boost.
On a GX390 Honda or Clone, being driven 1.16 times crank speed,
it would produce approximately 10 psi boost
On a 500cc four stroke, with the blower being driven 1.5:1  times crank speed,
it would produce approximately 12 psi boost.
On a 750cc four stroke, with the blower being driven 1.5:1  times crank speed,
it would produce approximately 3 psi boost.
On a 250cc two stroke, with the blower being driven 1.5:1  times crank speed,
it would produce approximately 12 psi boost.*
On a 125cc four stroke, with the blower being driven .5:1  times crank speed,
it would produce approximately 20 psi boost.

Over all length is 7.25"
Width is 5.375"
Height from inlet to outlet 4.3"
The 4 bolt inlet & outlet flanges makes it easy to fabricate custom mounts for manifolds, and carbs.

The drive pulley diameter is aprox. 2.2"
But could be changed out to a cog belt drive quite easily using normal kart belt drive parts.
 
Max continous blower rpm is 16,000.
They will take much more than that for short periods.
(these have been tested up past 18,000 rpm)
 
You should use forged internals to take higher boost numbers.
 
This is a used blower and has some minor scratches & scrapes on the rotors.
But because of the speed these turn, actual leakage past the rotors is minimal.

I 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.
I will help with figuring drive ratios, just e-mail
with your engine size,
type, Max RPM, and what type of boost pressure that you would like to produce.

Summit Racing has a good book on supercharger applications called Street Supercharging.
It sells for about $18, and is a good source of 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.
